[PATCH v2 0/3] multiboot: Use DMA instead port-based transfer

[Paolo Bonzini]

An updated version of the patch at
YWM6jboU9fUib6Iy@os.inf.tu-dresden.de/">https://patchew.org/QEMU/YWM6jboU9fUib6Iy@os.inf.tu-dresden.de/,
which includes the necessary glue for compatibility with older
machine types.  When fw_cfg DMA is disabled, the existing ROM
is used instead.

Marcus Hähnel (1):
  optionrom: add a DMA-enabled multiboot ROM

Paolo Bonzini (2):
  target/i386: move linuxboot_dma_enabled to X86MachineState
  target/i386: use DMA-enabled multiboot ROM for new-enough QEMU machine
    types
