Enable flash emulation in a PC system using pflash_cfi01.
v9:
* Add pc-1.1
* pc-1.0 uses previous rom firmware init code path
v8:
* Cleanup two chunks of debug code (printf messages)
* Fix comment in pc.h (pcflash.c => pc_sysfw.c)
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 to
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
Jordan Justen (3):
pc: Add pc-1.1 machine type
pflash: Support read-only mode
pc: Support system flash memory with pflash
