This patch is to enable u-boot as a payload which runs on top of Slim Bootloader(https://github.com/slimbootloader/slimbootloader) boot firmware for x86 platforms.
The Slim Bootloader is designed with multi-staqe architecture for the execution from reset vector to OS hand-off, and supports qemu, Apollolake, Whiskeylake and Coffeelake platforms consuming Intel FSP(https://github.com/IntelFsp/FSP) for silicon initialization including CAR and memory initialization. As multi-stage architecture, the Slim Bootloader adopts payload concept which is responsible for OS load from media devices and boot OS and it supports 32-bit PE32, EFI FV and ELF format payloads. The Slim Bootloader passes HOB(Hand Off Block) memory address, which has debug serial port info, memory map info, performance data info and etc., to a payload. U-boot configures serial port, dram, pci, tsc and others with the information from the HOB.
The compiled u-boot ELF supports usb, sata and sd/mmc boot which have been verified on qemu and other supported platforms.
