From c90b302d5f824a494905324a0abf6e69b7dc49f0 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Tue, 22 Sep 2020 12:45:25 -0600 Subject: [PATCH] x86: fsp: Update the FSP API with the end-firmware method This new method is intended to be called when UEFI shuts down the 'boot services', i.e. any lingering code in the boot loader that might be used by the OS. Add a definition for this new method and update the comments a little.
