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

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
0000000080000000-000000017ffffffe (prio 0, i/o): aspeed-ram-container
0000000080000000-00000000bfffffff (prio 0, ram): ram
00000000c0000000-ffffffffffffffff (prio 0, i/o): max_ram
Fix by using the correct value. We now have:
address-space: aspeed.fmc-ast2600-dma-dram
0000000080000000-000000017fffffff (prio 0, i/o): aspeed-ram-container
0000000080000000-00000000bfffffff (prio 0, ram): ram
00000000c0000000-ffffffffffffffff (prio 0, i/o): max_ram
