Subject: [v2, 00/16] Enable ARM Trusted Firmware for U-Boot
Date: Thu,  1 Oct 2020 02:15:58 -0700	[thread overview]
Message-ID: <20201001091614.184612-1-elly.siew.chin.lim@intel.com> (raw)

This is the 2nd version of patchset to Enable ARM Trusted Firmware
for U-Boot.

New U-boot flow with ARM Trusted Firmware (ATF) support:
SPL (EL3) -> ATF-BL31 (EL3) -> U-Boot Proper (EL2) -> Linux (EL1)

SPL loads the u-boot.itb which consist of:
1) u-boot-nodtb.bin (U-Boot Proper image)
2) u-boot.dtb (U-Boot Proper DTB)
3) bl31.bin (ATF-BL31 image)

Supported Platform: Intel SoCFPGA 64bits (Stratix10 & Agilex)

Patch status:
Have changes: Patch 2, 8, 9, 10, 11, 16
Other patches unchanged.

Detail changelog can find in commit message.

v1->v2:
--------
Patch 2:
-  Move soc64 folder from board/altera to board/intel folder

Patch 8:
-  Updated comments

Patch 9:
- Code clean up without functionality change

Patch 10:
- Code clean up without functionality change

Patch 11:
- Print error message and return instead of hang in socfpga_bridges_reset()
  when SMC call is failing.

Patch 16:
- Add CONFIG_SPL_LOAD_FIT_ADDRESS=0x02000000
- Move board/altera/soc64/fit_spl_atf.sh to board/intel/soc64/fit_spl_atf.sh
