4 Socionext UniPhier Armv8-A SoCs use Trusted Firmware-A (TF-A) as the secure
8 image from a non-volatile storage to the on-chip SRAM, and jumps over to it.
9 TF-A provides a special mode, BL2-AT-EL3, which enables BL2 to execute at EL3.
10 It is useful for platforms with non-TF-A boot ROM, like UniPhier. Here, a
14 `UniPhier BL`_. This loader runs in the on-chip SRAM, initializes the DRAM,

31 ---------
35 This is hard-wired ROM, so never corrupted. It loads the UniPhier BL (with
36 compressed-BL2 appended) into the on-chip SRAM. If the SoC fuses are blown,
41 This runs in the on-chip SRAM. After the minimum SoC initialization and DRAM
49 they are all authenticated by the standard mechanism of TF-A.

63 For a non-secure boot loader (aka BL33), U-Boot is well supported for UniPhier
64 SoCs. The U-Boot image (``u-boot.bin``) must be built in advance. For the build
65 procedure of U-Boot, refer to the document in the `U-Boot`_ project.

80 - Trusted Board Boot
86 To enable TBB, add the following options to the build command::
88 TRUSTED_BOARD_BOOT=1 GENERATE_COT=1 MBEDTLS_DIR=<path-to-mbedtls>
90 - System Control Processor (SCP)
92 If desired, FIP can include an SCP BL2 image. If BL2 finds an SCP BL2 image
93 in FIP, BL2 loads it into DRAM and kicks the SCP. Most of UniPhier boards
94 still work without SCP, but SCP provides better power management support.
96 To include SCP BL2, add the following option to the build command::
98 SCP_BL2=<path-to-SCP>
100 - BL32 (Secure Payload)
102 To enable BL32, add the following options to the build command::
104 SPD=<spd> BL32=<path-to-BL32>
106 If you use TSP for BL32, ``BL32=<path-to-BL32>`` is not required. Just add the
