* Use ACPI 5.1 everywhere, since we are constrained to use v5.x for
MADT compatibility.
* Clean up whitespaces and reorganize header declaration.
* Prefix all RPi related constant with RPI_ to make them clearer to
differentiate from regular EDK2 ones.
* Reference IndustryStandard/Acpi.h always.
* Remove explicit references to RPI4 for sources that we may be
factorized for both the Pi 3 and Pi 4 platform.

Use a proper aslc source to build the table.
Note that we use ACPI 5.1 for this table to match the MADT
constraints.

Makes sense. I was a bit too blind in trying to match the output of
acpiview.

Not really. I just picked those values from the acpiview output in the
Shell with the assumption that these and the IaPcBootArch flags (such as
lack of CMOS RTC which I'm hoping Microsoft can pick through different
means on ARM) were static values that needed to be preserved especially
as the blobs we are replacing here came from Microsoft.
I'll validate that it works with zero/default as you suggest below and
submit a v2.

Use code derived from JunoPkg to generate our serial tables and
also use PCDs where possible.

Actually this is the other way around, the 8250 is at AUX + 0x40.
Can we clean that up or is it too late?

Yeah, re-reading this I admit the comment is not too clear.
Let me try to rephrase this better in v2.

Actually my comment is about the code... Do you think we can clean the
RPi3/RPi4 codebase by changing
gEfiMdeModulePkgTokenSpaceGuid.PcdSerialRegisterBase?
If you don't have time for this, maybe you can add a /* TODO FIXME */?

Well, I'm planning to go with FixedPcdGet64 (PcdBcm283xRegistersAddress)
+ BCM2836_MINI_UART_OFFSET below in v2. So unless I'm missing something,
I think this solves the point you raised and will also remove the need
for the comment.

The PL011 can be a better choice for the serial console on the RPi4,
given that its baud clock is not derived from the CPU clock (which
may change under our feet unless we keep it fixed at a low rate), and
given the fact that the SBSA/SBBR specs that describe ARM specific
architectural requirements for ACPI only permit PL011 based UARTs to
begin with.
Therefore we add a new PL011_ENABLE build switch to tell the firmware
to use PL011 for all console serial I/O, including for TF-A, SPCR and
DBG2, as well as toggle the BlueTooth module to use the mini UART.
For the time being, the option is disabled by default because it
requires an overlay to be enabled in config.txt that pinmuxes the
PL011 TX/RX lines to the UART pins on the connector block.

Can we use relative to gBcm283xTokenSpaceGuid.PcdBcm283xRegistersAddress
instead?
And instead of RPI_UART_BASE_ADDRESS():
#define BCM283X_UART_OFFSET 0x00201000
#define BCM283X_UART_BASE_ADDRESS (FixedPcdGet64
(PcdBcm283xRegistersAddress) \

That's not a bad suggestion but if we do that then I'd rather introduce
2 new BCM2836_MINI_UART_OFFSET and BCM2836_PL011_UART_OFFSET constants
in Silicon/Broadcom/Bcm283x/Include/IndustryStandard/Bcm2836.h and then
set BCM283X_UART_BASE_ADDRESS to PcdBcm283xRegistersAddress + one or the
other.
The whole point was to avoid adding offsets, which may or may not remain
constant over the evolution of the Bcm283x family and derivatives, into
individual sources, because then we way have to hunt these constants in
places we may not even remember they exist.
On the other hand, I wouldn't mind avoiding that confusing 0x40 offset
we need to substract when using the 8250 UART. So I think I'll go with
the BCM283X_UART_BASE_ADDRESS + offset route, after adding an extra
patch to the series that adds the UART offset constants to
Silicon/.../Bcm2836.h.
Regards,
/Pete

If the family evolves, we can handle the new case or copy/paste again.
I insist with this modularity because then with little work we can
support the RPi1, using:
gBcm283xTokenSpaceGuid.PcdBcm283xRegistersAddress|0x20000000

If you don't mind doing the work, I believe this is the best way.
Thanks!

From: Andrei Warkentin <andrey.warkentin@gmail.com>
Since the RPi4 PCIe host bridge is not ECAM compliant, we cannot
expose it as a host bridge to the OS via ACPI, so we add a dummy
MCFG table. However, given the hardwired nature of this platform,
we can expose the xHCI controller that is guaranteed to live at
the base of the MMIO32 BAR window as a platform device directly.
It should be noted that the xHCI table is not finalized at this
stage, as Windows xHCI support is still a major question mark.

I don't think the MCFG table is mandatory, so if the OS complains
about this, we should fix the OS, not add dummy tables to work around
it.

Could we make this slightly less ugly, by setting MIN and MAX to
PCIE_CPU_MMIO_WINDOW and LEN to 1, and only updating MAX and LEN below

I'll do that in v2, for both entries.
Adding Andrei in CC just in case he wants to comment on that request.

Add an ACPI_BASIC_MODE_ENABLE flag to produces builds intended to run in
ACPI mode without any additional requirements (memory limits, acpi=force,
etc).
This flag is disabled by default.
