This patch series adds PEI phase to NXP LS1043ARDB Platform.
V2 series can be referred here:
https://edk2.groups.io/g/devel/message/56009

I have taken care of the review comments received on v2 and have
removed/added these commits w.r.t V2:

Removed in V3 (present in V2):
  07/28 Silicon/NXP: Implement SerialUartClockLib
  08/28 Silicon/NXP/LS1043A: Use BaseSerialPortLib16550 as SerialPortLib
  09/28 Silicon/NXP: Drop DUartPortLib

  These commits have been dropped for now. the discussion in ongoing for
  using BaseSerialPortLib16550 @ https://edk2.groups.io/g/devel/message/54629
  Once that discussion is concluded, i can submit these patches.

  21/28 Slicon/NXP: Add PlatformPei Lib

  as per discussion on https://edk2.groups.io/g/devel/message/56015
  i am dropping this commit for now. when i submit the patches to print more
  info about SOC, i can submit this patch with those.

  23/28 NXP/LS1043aRdbPkg/ArmPlatformLib: Use Allocate pool

  discussion ongoing @ https://edk2.groups.io/g/devel/message/56019

From: Pankaj Bansal <pankaj.bansal@nxp.com>

I2c lib is going to be used in PrePeiCore sec module to get the
System clock information from devices connected to i2c (like fpga
or clock generator)

since we don't have support of DXE modules this early in boot stage,
move the i2c controller functionality in library.

This I2cLib is not bug fix over I2cDxe.
The I2cLib has been completely re-written and not code movement from
I2cDxe to I2cLib
This is because I2cDxe has been written assuming that the I2c transaction
would always be of minimum two operations.
But this may not be the case always. e.g. RTC write in PCF2129 is single
operation.
Also the I2cDxe driver doesn't generate repeat start if i2c transaction is
more than two operations, it generates stop. This violates PI I2C spec.

Now we have removed these assumptions as well as added repeat start
between successive operations, which comply with PI I2C spec.

From: Pankaj Bansal <pankaj.bansal@nxp.com>

With latest edk2 codebase, sometimes i2c timeout is observed when
Network devices are being probed.
This is happening when gRT->GetTime request is ongoing.
gRT->GetTime triggers a read request to Real Time Clock which is
connected to I2c bus.
In between read request, if an event occurs, which also triggers
gRT->GetTime (i.e. RTC read), the I2c bus goes into unrecovered state.

This state is not even recovered, when rebooting the board.
We need to power off the board completely to recover i2c bus.

To prevent this, TPL level of I2c read is being raised to high, so that
no other event can preempt this. with this solution no timeout has been
observed so far.

From: Pankaj Bansal <pankaj.bansal@nxp.com>

There was a bug in I2C DXE implementation, which caused the Ds1307 RTC
device to issue two operation for register write, while this is a single
operation task. refer page 12 (Slave Receiver Mode (Write Mode)) on

https://datasheets.maximintegrated.com/en/ds/DS1307.pdf

From: Pankaj Bansal <pankaj.bansal@nxp.com>

The Soc info being printed can be removed from SOC lib.
We are in the process of implementing PEI Phase.
After PEI phase implementation this info would be printed in
common PEIM based on the information retrieved from PPIs.
e.g. gArmMpCoreInfoPpiGuid can be used to print cluser and
core info.

From: Pankaj Bansal <pankaj.bansal@nxp.com>

The structures elements and functions that are not necessary for booting
for now are being deleted.
Once the directory structure has been changed (i.e. we have clear
distinction between chassis code and header files and SOC code and header
files), we will put back the code and
structure components back at their appropriate respective place.

Also right now all the elements are being defined in structures, which are
not being used right now. So to simplify the code restructuring, I have
removed those for now. When we need to use those elements, we can define
those one by one.

From: Pankaj Bansal <pankaj.bansal@nxp.com>

The memory map of an SOC is fixed in hardware. it doesn't change with
platform that uses SOC. So, there is no need to keep PCDs for these values
and we can use macros for these in SOC header file.

Any Platform using the SOC, can make use of the SOC header file.

Keep the names and location of files as mentioned in ArmPlatformPkg.
This helps in porting the common changes (if any in future) easily.

From: Pankaj Bansal <pankaj.bansal@nxp.com>

RAM retrieval using SMC commands is common to all Layerscape SOCs.
Therefore, move it to commom MemoryInit Pei Lib.

Signed-off-by: Pankaj Bansal <pankaj.bansal@nxp.com>

Notes:
    - sort headers alphabetically
    - Moved DRAM region retrieval and Total DRAM size retrieval to separate
      functions
    - Fixed MemoryPeim function description
    - Modified check on FoundSystemMem = TRUE to check the RAM region against
      MemoryPeim function input arguments UefiMemoryBase and UefiMemorySize
    - (!DramRegions[Index].Size) => (DramRegions[Index].Size == 0)
    - (FoundSystemMem) => (FoundSystemMem == TRUE)
    - Added explaination for starting for loop from the last DRAM region

From: Pankaj Bansal <pankaj.bansal@nxp.com>

The SOC takes primary clocking input from the external signal (a clock
generator on board). The input (frequency) is multiplied using multiple
phase locked loops (PLL) to create a variety of frequencies which can
then be passed to a variety of internal logic, including cores and
peripheral IP modules.

Therefore, move the clock retrieval APIs to Platform Lib.
The Input clock is retrieved from board components in Platform Lib, and
passed on to SOC Lib APIs to get the correct clock for an IP (after PLL
multiplication).

From: Pankaj Bansal <pankaj.bansal@nxp.com>

The SwapMmio** APIs are supposed to be called indirectly via
GetMmioOperations** APIs.
Therefore, remove the SwapMmio** APIs from IoAccessLib.h and make
these APIs STATIC to IoAccessLib.c, so that no accidental call can
be made to these.

From: Pankaj Bansal <pankaj.bansal@nxp.com>

A Chassis is a base framework used for building SoCs.
We can think of Chassis/Soc/Platform(a.k.a Borad) in Object model terms.
Chassis is base. Soc is based on some Chassis.
Platform is based on some Soc.

SOCs that are designed around same chassis, reuse most of the components.

Therefore, add the package for Chassis2. LS1043A and LS1046A SOCs belong
to Chassis2.

Notes:
    - in patch description Oops -> Object model
    - Sorted includes alphabetically
    - removed direct calls to SwapMmio** APIs and used GetMmioOperations**

Now the we have added Chassis Package, move the chassis specific common
code for all SOCs belonging to same chassis to ChassisLib.

Use ChassisLib APIs in SocLib.

From: Pankaj Bansal <pankaj.bansal@nxp.com>

The SocLib contains code specific to an Soc. it should be part of
SOC package.
Therefore, move the SocLib to Soc Package.
Since we are moving the files to Soc Package, no need to mention the
Soc name in file names. Their location is enough to indicate for which
Soc the files are.

MemoryInitPeiLib would be linked to MemoryInitPeim, when we implement
PEI phase. therefore, move the library to directory of same name.

From: Pankaj Bansal <pankaj.bansal@nxp.com>

Add PEI phase to LS1043aRdb. This is needed becuase we need to have
dynamic PCDs support to be able to reserve memory before reporting
memory to UEFI fimrware.
Using PEI phase we are now also dynamically setting the
PcdSystemMemoryBase and PcdSystemMemorySize depending upon the DRAM
regions detected.
This in turn would depend on the DDR DIMMs installed on board.

These are trivial and I can fix them up here for any patches that are
ready to push, but if there is a v4, can you check and update?
Verify by importing the patches to a clean branch using git am of the
patches you would send to the list.

(Note to self - we really should add a test for this to PatchCheck.py,
I've raised https://bugzilla.tianocore.org/show_bug.cgi?id=2685 to
covert this.)

Regards,

Leif

3 lines above this, the commit message says it *is* being moved.

I'm not asking for a technical debate in the commit message.
Please throw away all text in this message and write a new one from
scratch describing what this patch *does*.

Then please submit a v4 of this patch only.
Please also address the blank lines at EOF pointed out below.

It is an improvement, but there is still nothing in here that makes it
obvious why this is being done twice. The referenced u-boot patch does
it only once.

Hmm, furthermore, I don't see this function called at all? Why is it
included? If you delete it (and its declaration in .h), I'm OK with
the result.

Breaking this up into helper functions has improved readability a lot,
but this one could do with some more clarification. Can we have a
#define with a descriptive name to explain better than
ArmSmcArgs.Arg0 != 0 why we should return 0?

Do we *need* to check for RemainingDramSize in the loop condition?
Would it not be better to process all regions and flag an error if
RemainingDramSize == 0 is not reached?

Hmm, right, so NumRegions is really just the size of our data
structure - but how about something like:

   for (Index = 0; Index < NumRegions; Index++) {
     ...

     if (RemainingDramSize == 0) {
       return EFI_SUCCESS;
     }
   }

   DEBUG ((DEBUG_ERROR, ...

   return EFI_BUFFER_TOO_SMALL;

This call implicitly discards the return code. I don't think that's
necessarily the wrong decision here, but it would be more clear (and
prevent compilers and code analysis tools from objecting) if
explicitly casting it away with (VOID).

This bit didn't jump out at me, but when I looked at 16/24 I nearly
choked on my coffee.

When the IoAccessLib was being reviewed, I requested that the
16/32/64-bit accessors be merged
(https://edk2.groups.io/g/devel/message/34403). They ended up not
being, and I didn't notice so pushed the result anyway.

I have sent out a patch for review/test to do this, but it will need
to go in before this patch - and it *will* require changes to this
one:
  MMIO_OPERATIONS_32 -> MMIO_OPERATIONS
  GetMmioOperations32 -> GetMmioOperations

If those changes are done, there is no need for me to re-review this
one.

Regards,

Leif

The intended usage model for IoAccessLib is to retrieve the function
pointer struct once and then always refer to it. Since this is a
library, we could have a CONSTRUCTOR function (specified in the .inf)
and do something like:

STATIC MMIO_OPERATIONS mDcfgOps;

/**
  Read Dcfg register

  @param  Address The MMIO register to read.

  @return The value read.
**/
UINT32
EFIAPI
DcfgRead32 (
  IN  UINTN     Address
  )
{
  return mDcfgOps->Read32 (Address);
}

/**
  Write Dcfg register

  @param  Address The MMIO register to write.
  @param  Value   The value to write to the MMIO register.

  @return Value.

**/
UINT32
EFIAPI
DcfgWrite32 (
  IN      UINTN                     Address,
  IN      UINT32                    Value
  )
{
  return mDcfgOps->Write32 (Address, Value);
}

...

/**
  The constructor function initializes the IoAccessLib
  function pointer structure.

  @retval RETURN_SUCCESS   The constructor always returns EFI_SUCCESS.

**/
EFI_STATUS
EFIAPI
ChassisLibConstructor (
  VOID
  )
{
  mDcfgOps = GetMmioOperations (FeaturePcdGet (PcdDcfgBigEndian));

  return EFI_SUCCESS;
}

I had thought of this, but decided against it because of this reason:
    The order of Library constructor call for a module cannot be guaranteed.
    https://edk2.groups.io/g/devel/message/57254  is an good example of this.
    BaseDebugLibSerialPortConstructor would need to depend on ChassisLibConstructor,
    to retrieve the UART clock frequency. If the constructor calls are not guaranteed, BaseDebugLibSerialPortConstructor
    would fail and it would cause ASSERT due to ASSERT_RETURN_ERROR (Status)

If this is a problem (and I recall Ard pointing out some shortcomings
in the dependency handling in the past), we can solve this with an
explicit initialisation call in the SoC or platform init code.

You mean put ChassisLibConstructor() call in SerialPortInitialize () ?

Or before the call to SerialPortInitialize in ChassisInit.

But SerialPortInitialize would be called from each module.
Each module that has SerialPort and ChassiLib linked to it would have a
local copy of mDcfgOps, which needs to be initialized.

Why would multiple modules need to initialize the serial port?

On the surface it makes more sense for the function that initializes
mmio accessors for chassis to be in the chassis initialization
function.

In the current tree I can only see one user of SerialPortLib and one
of ChassisLib - but you are suggesting there will be several per
platform? If so, A better splution may ne to consider wrapping
DcfgRead32/DcfgWrite32 in a protocol instead of depending on the
ChassisLib.

That's how the DebugLib has been designed.
DebugLib is used by all modules to print info on console.
BaseDebugLibSerialPortConstructor calls SerialPortInitialize.
So SerialPortInitialize is called by all the modules.

Which is the reason when I forked the BaseSerialPortLib16550,
I removed SerialPortInitalize functionality.

The protocol would not be available in SEC and PEI phase.

Sure, but the bit where ChassisLib returns the active clock
configuration does not need to happen for each initialization.
That value can be cached.

The only mechanism I know for passing a cached value between different modules
is either use PCDs or use HOBs.
We have already explored both in https://edk2.groups.io/g/devel/message/57254
and https://edk2.groups.io/g/devel/message/56530 

Moreover the compiler can optimize the PcdDcfgBigEndian evaluation.
So no overhead would be observed in evaluating PcdDcfgBigEndian in every call.

The intent is to remain as close as possible to reference platform, so that any future changes can be ported easily.

It's not necessary to call I2cEarlyInitialize for all I2c controllers.
This function has been written so that i2c bus can be initialized to read the system clock
from a clock generator or an FPFA.

To make a call to I2cInitialize, we need to know the I2cBusClock, which is a derivative of
System clock. I2cBusClock is calculated after PLL multiplication to system clock.
Therefore, we won't be able to call I2cInitialize without knowing System clock.

The idea is that for i2c controller to which clock generator or an FPFA is connected, we first
Call I2cEarlyInitialize. Then we read system clock and then we can call I2cInitialize for that
Controller as well as any other i2c controller(s) in the system.

So, for all i2c controllers (except one) I2cInitialize would be called and not I2cEarlyInitialize

OK. So, I am OK with that as en end result, but since the function is
not used at all in this patchset, can it be purged from here and
introduced just before it is needed with a subsequent set?
That will make its intended use *much* more clear.

That was discussing what to do with regards to the generic 16550
driver. If we go with Laszlo's suggestion[1] for a separate
SerialUartClockLib instead of adding a vendor GUID HOB *into the
generic driver*, that does not preclude your using a HOB to cache the
value in your platform code for later use in your own
SerialUartClockLib implementation.

I don't question that, but that was always going to be the case anyway
- especially with LTO. The point is reducing code duplication -
especially for weird and wacky hardware workarounds.

Caching using a HOB is a bit problematic, given that 
SerialPortInitialize() does not honour constructor ordering (it may be 
called before any of the constructors), and so whether we implement 
Laszlo's suggestion or not, using a HOB to cache anything that is 
required to set the correct baud rate is not going to work (given that 
HobLib may rely on its constructor to be able to access the HOB list)

Unfortunately, that leaves us with little else, given that we cannot use 
global variables either, since BASE libraries may be incorporated into 
PEIMs that run execute-in-place from ROM.

So the bottom line is that we don't have that many options that are 
actually feasible, and so converging on one of the non-optimal ones is 
all that we can really hope for at this point.

Have to agree here :-)

Argh, OK. I hadn't tweaked this - so thanks for pointing it out.

OK, given that:
Reviewed-by: Leif Lindholm <leif@nuviainc.com>
for this patch in its current state.

Just, please use a single call to set up the struct pointer for future
components where that is possible.
