[Qemu-devel] [PATCH v7 0/2] PC system flash support

[Jordan Justen]

Enable flash emulation in a PC system using pflash_cfi01.

v7:
* Do not add system firmware to qemu roms
* If kvm is enabled, copy pflash drive contents into a
  read-only ram region, since kvm cannot currently execute
  code from a pflash device.
* Rename pcflash.c to pc_sysfw.c

v6:
* Rebase for memory API
* pflash_cfi01: Set error in status register when a write or
  erase is attempted in read-only mode.
* Add system firmware to qemu roms

v5:
* Enable pflash read-only mode
* Enable -drive with if=pflash to define system firmware image

v4:
* Rebase

v3:
* Fix code style issues
* Add additional comments

v2:
* Convert debug printf to DPRINTF

  pflash: Support read-only mode
  pc: Support system flash memory with pflash
