From 32151d40172870e7772b1a393935001979a01aea Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Tue, 12 Jun 2018 08:36:18 -0700 Subject: x86: Add generic EFI payload support It is possible to create a generic EFI payload for all x86 boards. The payload is configured to include as many generic drivers as possible. All stuff that touches low-level initialization are not allowed as such is the EFI BIOS's responsibility. Platform specific drivers (like gpio, spi, etc) are not included.
