[v4 0/7] Add Vendor Authorized Boot (VAB) support

[Siew Chin Lim]

This is the 4th version of patchset to add Vendor Authorized Boot (VAB)
support for Intel Agilex SoC device.

Vendor Authorized Boot is a security feature for authenticating
the images such as U-Boot, ARM trusted Firmware, Linux kernel,
device tree blob and etc loaded from FIT. After those images are
loaded from FIT, the VAB certificate and signature block appended
at the end of each image are sent to Secure Device Manager (SDM)
for authentication. U-Boot will validate the SHA384 of the image
against the SHA384 hash stored in the VAB certificate before
sending the image to SDM for authentication.

Patch status:
Have changes: Patch 2, 7
Other patches unchanged.

Detail changelog can find in commit message.

v3->v4:
--------
Patch 2:
- Move function 'board_fit_image_post_process' and 'board_prep_linux' from
  secure_vab.c to board.c

Patch 7:
- Replace CONFIG_TARGET_SOCFPGA_STRATIX10/AGILEX with CONFIG_TARGET_SOCFPGA_SOC64.
- Add this patch into 'VAB' series because it is depending on
  CONFIG_TARGET_SOCFPGA_SOC64 patch.
