At present Linux kernel loaded from U-Boot as an EFI payload does not boot. This fills in kernel's boot params structure with the required critical EFI information like system table address and memory map stuff so that kernel can obtain essential data like runtime services and ACPI table to boot. With this patch, now U-Boot as an EFI payload becomes much more practical: it is another option of kernel bootloader, ie, can be a replacement for grub.
