I think we have some room to improve things here, some right now and some as follow-up work.
[snip]
+Sources: +-------- +1. Trusted Firmware-A:
- Tree: https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/
- Branch: master
+2. OP-TEE:
- Tree: https://github.com/OP-TEE/optee_os.git
- Branch: master
+3. U-Boot:
- Tree: https://source.denx.de/u-boot/u-boot
- Branch: master
+4. TI Linux Firmware:
- Tree: git://git.ti.com/processor-firmware/ti-linux-firmware.git
- Branch: ti-linux-firmware
+Build procedure: +---------------- +1. Trusted Firmware-A:
+.. code-block:: bash
- $ make CROSS_COMPILE=aarch64-none-linux-gnu- ARCH=aarch64 PLAT=k3 \
TARGET_BOARD=lite SPD=opteed+2. OP-TEE:
+.. code-block:: bash
- $ make PLATFORM=k3 CFG_ARM64_core=y CROSS_COMPILE=arm-none-linux-gnueabihf- \
CROSS_COMPILE64=aarch64-none-linux-gnu-
So, we have some generic wording on how to build TF-A and OP-TEE up in doc/board/ti/k3.rst. It should be made clearer if needed that unless otherwise indicated, top of tree is expected to be used for TF-A/OP-TEE and ti-linux-firmware for the ti-linux-firmware repo. Then just state that TF-A should be which of {lite|generic|j784s4} as it is a $family device. And we then drop much of the duplication here.
+3. U-Boot:
+* 3.1 R5:
+.. code-block:: bash
- $ make ARCH=arm am62x_beagleplay_r5_defconfig
- $ make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabihf- \
BINMAN_INDIRS=<path/to/ti-linux-firmware>+* 3.2 A53:
+.. code-block:: bash
- $ make ARCH=arm am62x_beagleplay_a53_defconfig
- $ make ARCH=arm CROSS_COMPILE=aarch64-none-linux-gnu- \
BL31=<path/to/trusted-firmware-a/dir>/build/k3/lite/release/bl31.bin \TEE=<path/to/optee_os/dir>/out/arm-plat-k3/core/tee-raw.bin \BINMAN_INDIRS=<path/to/ti-linux-firmware>
And can drop this.
+Target Images +-------------- +Copy the below images to an SD card and boot:
+* tiboot3-am62x-gp-evm.bin from step 3.1 as tiboot3.bin +* tispl.bin_unsigned from step 3.2 as tispl.bin +* u-boot.img_unsigned from step 3.2 as uboot.img
Then reword this to be "from R5" or "from Axx" build.
+Image formats: +--------------
+The Image format follows the standard AM62X image format [1]_.
+A53 SPL DDR Memory Layout +-------------------------
This is unchanged for all AM62 platforms, yes? That should be in a generic am62 doc.
