[Qemu-devel] [PATCH 0/6] Fix -kernel with SeaBIOS v2

[Alexander Graf <agraf@suse.de>]

SeaBIOS clears RAM between we write our -kernel image to RAM and the int19
handler gets triggered.

So in order to work around that, I sat down and implemented Avi's suggestion
of "downloading" all blobs in runtime from the fw_cfg interface

Thanks to glommer who talked me into doing it ;-).

v1 -> v2:

  - rename copy_rom -> rom_copy
  - introduce fw_cfg compat loader for loadvm

Alexander Graf (6):
  Make fw_cfg interface 32-bit aware
  Introduce rom_rom
  Convert multiboot to fw_cfg backed data storage
  Move common option rom code to header file
  Convert linux bootrom to external rom and fw_cfg
  Add linuxboot to BLOBS
