Applied to my trivial-patches branch.

[PATCH v2 1/8] hw/arm/aspeed: Correct DRAM container region size

2020-06-01 Thread Philippe Mathieu-Daudé
memory_region_set_size() handle the 16 Exabytes limit by
special-casing the UINT64_MAX value. This is not a problem
for the 32-bit maximum, 4 GiB.
By using the UINT32_MAX value, the aspeed-ram-container
MemoryRegion ends up missing 1 byte:

 $ qemu-system-arm -M ast2600-evb -S -monitor stdio
 (qemu) info mtree

  address-space: aspeed.fmc-ast2600-dma-dram
8000-00017ffe (prio 0, i/o): aspeed-ram-container
  8000-bfff (prio 0, ram): ram
  c000- (prio 0, i/o): max_ram

Fix by using the correct value. We now have:

  address-space: aspeed.fmc-ast2600-dma-dram
8000-00017fff (prio 0, i/o): aspeed-ram-container
  8000-bfff (prio 0, ram): ram
  c000- (prio 0, i/o): max_ram
