This series adds DMA support to QEMU FW_CFG also on the read size,
allows a completely dma-less PIO mode and adds support for parsing
the QEMU options for: -kernel, -initrd, -uuid and -append.
Ahmad Fatoum (6):
firmware: qemu_fw_cfg: use wider PIO reads if applicable
param: support uuid/guid parameter type
lib: smbios: add support for setting product UUID
common: boards: qemu: process some standard fw_cfg keys
firmware: qemu_fw_cfg: add proper DMA and PIO bidirectional operating
modes
ARM: configs: multi: enable QEMU FW_CFG
