[PATCH v4 0/6] hw/arm/aspeed_ast2700-fc: Fix null pointer dereference

[Steven Lee via <qemu-devel@nongnu.org>]

Clang's sanitizer reports a runtime error when booting with
'-net nic -net user', due to a null pointer being passed
to memory_region_find(), which subsequently triggers a crash in
flatview_lookup().

Root cause:
- Missing NIC configuration in the CA35 initialization.

Fix:
- Reduce ca35 ram size from 2GiB to 1GiB to align with ast2700a1-evb,
  where the ram-container is defined as 1GiB in its class.
- Add nic configuration in ast2700fc's ca35 init function.


v2:
- Split the CA35 memory mapping into a separate patch.
- Added a new patch to fix BMC memory mapping in the fby35 machine,
  which had a similar issue (unmapped system_memory).
- Removed Change-Id tag from commit messages

v3:
- Fixed issue with incorrectly inheriting TYPE_ASPEED_MACHINE.
- Rewrote the commit message for "Map BMC memory into system memory".
- Added more details to the commit message for "Fix unimplemented region
  overlap with VBootROM".

v4:
- Split the first patch "Fix null pointer dereference" into two patches.
- Remove the patch "hw/arm/aspeed_ast27x0: Fix unimplemented
  region overlap with vbootrom".
