ARM: meson: add support for Libre Computer aml-s905d3-cc
Add support for the Libre Computer aml-s905d3-cc "Solitude" board: https://libre.computer/products/aml-s905d3-cc/ The Solitude board has a Credit Card form factor, similar to the the previous "Le Potato" card, but with the Amlogic A311D SoC, MIPI DSI and CSI connectors. PoE header and a single USB2 Type-C connector replacing the microUSB one for power and USB 2.0. The board has an embedded SPI NOR flash, and EFI Capsule support is added. The GUID is dynamically generated for the board, to get it: => efidebug capsule esrt ======================================== ESRT: fw_resource_count=1 ESRT: fw_resource_count_max=1 ESRT: fw_resource_version=1 [entry 0]============================== ESRT: fw_class=4302C3CB-2502-5EFE-87E0-894A8A322893 ESRT: fw_type=unknown ESRT: fw_version=0 ESRT: lowest_supported_fw_version=0 ESRT: capsule_flags=0 ESRT: last_attempt_version=0 ESRT: last_attempt_status=success ======================================== On the host (with the aml_encrypt_g12a result binary): $ eficapsule --guid 4302C3CB-2502-5EFE-87E0-894A8A322893 -i 1 u-boot.bin u-boot.cap On the board (from USB disk containing u-boot.cap at root): => load usb 0:1 $kernel_addr_r u-boot.cap => efidebug capsule update $kernel_addr_r The binary will then be flashed on the SPI.

|
||||
- 2 or 4GB LPDDR4 SDRAM
|
||||
- Gigabit Ethernet
|
||||
- HDMI 2.1 display
|
||||
- 40-pin GPIO header
|
||||
- 4 x USB 3.0 Host, 1 x USB 2.0 Type-C
|
||||

||||
U-Boot Compilation
|
||||
------------------
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ export CROSS_COMPILE=aarch64-none-elf-
|
||||
$ make aml-s905d3-cc_defconfig
|
||||
$ make
|
||||
|
||||
U-Boot Signing with Pre-Built FIP repo
|
||||
--------------------------------------
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ git clone https://github.com/LibreELEC/amlogic-boot-fip --depth=1
|
||||
$ cd amlogic-boot-fip
|
||||
$ mkdir my-output-dir
|
||||
$ ./build-fip.sh aml-s905d3-cc /path/to/u-boot/u-boot.bin my-output-dir
|
||||
|
||||
Then write U-Boot to SD or eMMC with:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ DEV=/dev/boot_device
|
||||
$ dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1
|
||||
$ dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=1 count=440
