From cf376037e232869fd86cf2658bdf297fbe004055 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 29 Dec 2021 11:57:48 -0700 Subject: [PATCH] efi: Mention that efi_info_get() is only used in the stub This provides access to EFI tables after U-Boot has exited boot services. It is not needed in the app since boot services remain alive and we can just call them whenever needed. Add a comment to explain this.
