[U-Boot] [PATCH v6 0/8] x86: qemu: 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
