> Subject: [U-Boot] [PATCH v2 0/8] x86: Add basic Slim Bootloader payload
> support
> 
> 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.
