Our patches are similar in case of fw_cfg apis support it brings to
u-boot but our use case of using them are different.

Hi Miao,
Thanks for the patches.
I made an initial attempt to support the fw_cfg in U-boot for QEMU to
get acpi tables by fw_cfg for qemu-x86 targets.
The idea was if we find acpi tables in fw_cfg try loading them,
otherwise fallback to the builtin acpi tables.
The patch was dropped mainly beca
The fw_cfg interface provided by QEMU allow guests to retrieve various
information
about the system, e.g. cpu number, variaous firmware data, kernel setup, etc.
The
fw_cfg interface can be accessed through 3 IO ports (on x86), using x86 in/out
instructions.
