Subject: hw/block/pflash_cfi02: Set rom_mode to true in pflash_setup_mappings()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=326d02c34a92f6e30fa3231be83efda43bac36f8;p=qemu.git

hw/block/pflash_cfi02: Set rom_mode to true in pflash_setup_mappings()

There is only one call to pflash_setup_mappings(). Convert 'rom_mode'
to boolean and set it to true directly within pflash_setup_mappings().
