[U-Boot] [PATCH v7 3/9] x86: Add a common HOB library
Park, Aiden
aiden.park at intel.com
Mon Jul 29 04:35:48 UTC 2019
FSP(CONFIG_HAVE_FSP) and Slim Bootloader(CONFIG_SYS_SLIMBOOTLOADER)
consume HOB(CONFIG_USE_HOB) data from the each HOB list pointer.
Add a common HOB library in lib/hob.c and include/asm/hob.h.
Signed-off-by: Aiden Park <aiden.park at intel.com>
---
Changes in v7:
* Split HOB library into EFI_GUID pre-work and making a common library
Changes in v6:
* Use CONFIG_USE_HOB
* Change struct efi_guid to efi_guid_t
* Use EFI_GUID to define GUIDs
Changes in v3:
* Create a common HOB libary from fsp_hob and fsp_support
