@ -37,6 +37,17 @@ The TF-A image must be properly formatted with a STM32 header structure
for ROM code is able to load this image.
Tool stm32image can be used to prepend this header to the generated TF-A binary.
Boot with FIP
~~~~~~~~~~~~~
The use of FIP is now the recommended way to boot STM32MP1 platform.
Only BL2 (with STM32 header) is loaded by ROM code. The other binaries are
inside the FIP binary: BL32 (SP_min or OP-TEE), U-Boot and their respective
device tree blobs.
STM32IMAGE bootchain
~~~~~~~~~~~~~~~~~~~~
Although still supported, this way of booting is not recommended.
Pease use FIP instead.
At compilation step, BL2, BL32 and DTB file are linked together in a single
binary. The stm32image tool is also generated and the header is added to TF-A
binary. This binary file with header is named tf-a-stm32mp157c-ev1.stm32.

Boot with FIP
~~~~~~~~~~~~~
You need to build BL2, BL32 (SP_min or OP-TEE) and BL33 (U-Boot) before building FIP binary.

TF-A BL32 (SP_min)
__________________
If you choose not to use OP-TEE, you can use TF-A SP_min.
To build TF-A BL32, and its device tree file:
.. code:: bash
make CROSS_COMPILE=arm-none-eabi- PLAT=stm32mp1 ARCH=aarch32 ARM_ARCH_MAJOR=7 \
AARCH32_SP=sp_min DTB_FILE_NAME=stm32mp157c-ev1.dtb bl32 dtbs

________
To build TF-A BL2 with its STM32 header for SD-card boot:
.. code:: bash
make CROSS_COMPILE=arm-none-eabi- PLAT=stm32mp1 ARCH=aarch32 ARM_ARCH_MAJOR=7 \
DTB_FILE_NAME=stm32mp157c-ev1.dtb STM32MP_SDMMC=1
For other boot devices, you have to replace STM32MP_SDMMC in the previous command
with the desired device flag.
This BL2 is independent of the BL32 used (SP_min or OP-TEE)

----------------
The SD-card has to be formated with GPT.
Boot with FIP
~~~~~~~~~~~~~
The SD-card has to be formatted with GPT.
It should contain at least those partitions:
- fsbl: to copy the tf-a-stm32mp157c-ev1.stm32 binary (BL2)
- fip: which contains the FIP binary
Usually, two copies of fsbl are used (fsbl1 and fsbl2) instead of one partition fsbl.
