[Qemu-devel] [PATCH v3] target/xtensa: xtfpga: provide default memory sizes

[Max Filippov <jcmvbkbc@gmail.com>]

Provide default RAM sizes for all XTFPGA boards, so that when started
without -m option they do the right thing.

Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com>
---
Changes v2->v3:
- add XTFPGA_MMU_RESERVED_MEMORY_SIZE definition and express Xilinx board
  memory sizes using it as suggested by Philippe;

Changes v1->v2:
- fix memory sizes for ml605 and kc705 with MMU
