[Qemu-devel] [PATCH 5/5] mips_malta: Clean up definition of flash memory size somewhat
Posted by Philippe Mathieu-Daudé 6 years, 8 months ago
From: Markus Armbruster <armbru@redhat.com>

pflash_cfi01_register() takes a size in bytes, a block size in bytes
and a number of blocks.  mips_malta_init() passes BIOS_SIZE, 65536,
FLASH_SIZE >> 16.  Actually consistent only because BIOS_SIZE (defined
in include/hw/mips/bios.h as (4 * MiB)) matches FLASH_SIZE (defined
locally as 0x400000).  Confusing all the same.

Pass FLASH_SIZE instead of BIOS_SIZE.
