[U-Boot] Boot Linux using EFI environment from u-boot

[U-Boot] Boot Linux using EFI environment from u-boot

[Poonam Aggrwal]

Hello Alex

I am not sure, but it seems it is possible to boot Linux from u-boot using EFI environment.
So what I intend to do is that without using UEFI , if I can boot Linux and make EFI variables available for Linux.

Can you please help me on how I can use this configuration.

Many Thanks
Poonam

Linux will only have access to UEFI variables through the UEFI Runtime 
Services which again are only provided to the OS when it is booted 
through the "bootefi" command.

Keep in mind that UEFI variable services are currently work in progress 
and may or may not fit your needs just yet.

It seems I can run grub.efi on u-boot and that would boot Linux.
Let me try this...
