Hi,

This is a second version of DRAM handling and other general improvements.
Two patches were significantly reworked and as a result we support
now not only overall size detection, but also remap parameters.
This way we are immune to future remap changes done in the early
firmware. All above with better readability.

The patches are available in the github:
https://github.com/MarvellEmbeddedProcessors/edk2-open-platform/commits/mem-upstream-r20171025

I'm looking forward to your comments or remarks.

Best regards,
Marcin

Changelog:
1/8
  - Add comment for calling Stall

4/8
  - s/VirtualMemoryTable/mVirtualMemoryTable/
  - restore ASSERT for table elements
  - correct commit log (s/ATF/ARM-TF/)
  - add dynamic remap enable/parameters detection
  - move config space base address to PCD
  - use macros

6/8
  - s/DramSizeGet/GetDramSize/
  - add 'IN OUT' to GetDramSize argument
  - s/AreaLengthMap/RegionCode/
  - use macros to hide arithmetics and increase readability
  - replace humongous switch/case with small if/else

2/8, 3/8, 5/8, 7/8, 8/8
  - Add RBs

From: Ard Biesheuvel <ard.biesheuvel@linaro.org>

Add an implementation of EFI_RNG_PROTOCOL so that the OS loader has
access to entropy for KASLR and other purposes (i.e., seeding the OS's
entropy pool very early on).

In order to prevent fragmentation of the UEFI memory map, increase the
sizes of the preallocated regions. Note that this does not increase the
memory footprint of UEFI, it just modifies it allocation policy to keep
similar region types together.

When switching to generic PSCI reset library, obsolete parts
of previous custom reset library (PCDs, documentation) remained.
Remove them.

The Armada 70x0/80x0 DRAM controller allows a single window of DRAM
to be remapped to another location in the physical address space. This
allows us to free up some memory in the 32-bit addressable region for
peripheral MMIO and PCI MMIO32 and CONFIG spaces.

This patch adjusts memory blocks to the configuration done in ARM-TF.
The remap parameters are otained directly from the registers. Moreover,
the configuration space base address is now configurable via PCD, so
that to satisfy a case, when remap is not enabled in the early firmware
and ensure, that PcdSystemMemorySize is not overlapping it.

From: Ard Biesheuvel <ard.biesheuvel@linaro.org>

The default MemoryInitPeiLib implementation insists on reserving the
region occupied by our own FV, while this is not necessary at all (the
compressed payload is uncompressed elsewhere, so the moment we enter
DXE core, we don't care about the FV contents in memory)

So clone MemoryInitPeiLib and modify it to suit our needs.

Instead of using hardcoded value in PcdSystemMemorySize PCD,
obtain DRAM size directly from SoC registers, which are filled
by firmware during early initialization stage.

It would be even nicer this one could be abstracted away in another
macro (now everything else is this clean, it does sort of stand out).

I guess we should also check for the reserved ones.
I'm also a fan of the "common case first" approach to if-statements.

So, could we squash these two together?:
if (DRAM_REGION_SIZE_EVEN (RegionCode)) {
  *MemSize += GET_DRAM_REGION_SIZE_EVEN (RegionCode);
} else if (DRAM_REGION_SIZE_ODD (RegionCode)) {
  *MemSize += GET_DRAM_REGION_SIZE_ODD (RegionCode);
} else {
  DEBUG ((DEBUG_ERROR,
    "%a: Invalid memory region code (0x%x) for CS#%d\n",
    __FUNCTION__,
    RegionCode,
    Cs));
    return EFI_INVALID_PARAMETER;
}

Where
#define DRAM_REGION_SIZE_ODD(x)  ((x) <= 4)
#define DRAM_REGION_SIZE_EVEN(x) (((x) >= 7) && ((x) <= 26))

(I use decimal numbers, because so does the documentation.)
