[U-Boot] [PATCH v2 03/17] efi_loader: pass GUIDs as const efi_guid_t *
Heinrich Schuchardt
xypron.glpk at gmx.de
Thu Oct 5 14:35:53 UTC 2017
We need to call some boottime services internally.
Our GUIDs are stored as const efi_guid_t *.
The boottime services never change GUIDs.
So we can define the parameters as const efi_guid_t *.
