README.efi has the details. The stub can be 32-bit or 64-bit (CONFIG_EFI_STUB_64BIT), allowing it to run from either variant of UEFI. U-Boot itself only supports 32-bit mode at present, so in either case the CPU will change to 32-bit mode in the stub. See x86-fit-boot.txt for how to use the standard FIT. I've just sent three patches which update the documentation a bit also, since some features are not mentioned. http://patchwork.ozlabs.org/patch/649221/ http://patchwork.ozlabs.org/patch/649222/ http://patchwork.ozlabs.org/patch/649223/ Regards, Simon _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
