[U-Boot] [PATCH v9 2/9] x86: lib: fsp: Use EFI_GUID and efi_guid_t
Park, Aiden
aiden.park at intel.com
Sat Aug 3 08:30:20 UTC 2019
Use existing EFI_GUID and efi_guid_t instead of struct efi_guid.
This is pre-work before making a common HOB library.
- Change 'struct efi_guid' to efi_guit_t
- Remove 'struct efi_guid'
- Define GUIDs with EFI_GUID() macro
- Use guidcmp() instead of compare_guid()
- Remove compare_guid()

Changes in v8:
* Remove unnecessary parentheses reported from checkpatch
Changes in v7:
* Split HOB library into EFI_GUID pre-work and making a common lirary
