[PATCH 0/8] hw: Fix some incomplete memory region size

[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, but
in some places we incorrectly use UINT32_MAX instead of
4 GiB, and end up missing 1 byte in the memory region.

This series fixes the cases I encountered.
Also included few patches while reviewing, I replaced some
magic values by the IEC binary prefix equivalent.

Regards,

Phil.

By using the UINT32_MAX value, the aspeed-ram-container
MemoryRegion ends up missing 1 byte:
