[Qemu-devel] [PATCH 2/2] hw/mips/mips_malta: don't make bios region 'nomigrate'

[Peter Maydell <peter.maydell@linaro.org>]

Currently we use memory_region_init_rom_nomigrate() to create
the "bios.1fc" memory region, and we don't manually register
it with vmstate_register_ram(). This currently means that its
contents are migrated but as a ram block whose name is the empty
string; in future it may mean they are not migrated at all. Use
memory_region_init_ram() instead.

Note that this is a a cross-version migration compatibility break
for the "malta" machine.
