Re: [U-Boot] [PATCH 0/7] add fw_cfg interface support for qemu-x86 targets

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

[U-Boot] [PATCH 0/7] add fw_cfg interface support for qemu-x86 targets

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. - 0x510: select configuration items
