From 567dfef2fe4affe28e8e65b54677f24995b98a5e Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Fri, 24 Sep 2021 18:30:21 -0600 Subject: x86: Show some EFI info with the bdinfo command It is useful to see some basic EFI info with the command as it forms part of the information about a board. Add a hook for this and show the table address as a start. While here, fix an invalid cast in setup_efi_info(). Note that this function is using a data structure defined by Linux so we cannot change it. Also note that ulong is used since this is the standard in U-Boot (>6k uses), despite there being quite a bit of the more verbose uintptr_t (930 uses).
