Subject: [U-Boot] [PATCH 1/1] efi_loader: efi_guid_t must be 64-bit aligned
Date: Sat, 15 Dec 2018 22:40:47 +0100 [thread overview]
Message-ID: <20181215214047.26455-1-xypron.glpk@gmx.de> (raw)
The UEFI Specification Version 2.7 Errata A defines:
"EFI_GUID
128-bit buffer containing a unique identifier value.
Unless otherwise specified, aligned on a 64-bit boundary."
Before this patch efi_guid_t was 8-bit aligned.
