Subject: [Qemu-devel] [PATCH v7 0/2] PC system flash support
Date: Wed, 2 Nov 2011 21:19:21 -0700 [thread overview]
Message-ID: <1320293963-14629-1-git-send-email-jordan.l.justen@intel.com> (raw)
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

pc: Support system flash memory with pflash
