[PATCH v1 00/16] Enable ARM Trusted Firmware for U-Boot

[Chee Hong Ang]

Repost of the following patchs:
https://lists.denx.de/pipermail/u-boot/2020-March/402705.html

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)

Now, U-Boot Proper is running in non-secure mode (EL2), it invokes
SMC/PSCI calls provided by ATF to perform COLD reset, System Manager
register accesses and mailbox communications with Secure Device Manager
(SDM).

Steps to build the U-Boot with ATF support:
1) Build U-Boot
2) Build ATF BL31
3) Copy ATF BL31 binary image into U-Boot's root folder
4) "make u-boot.itb" to generate u-boot.itb
