Draft: Merge all amlogic U-Boot packages
TODO:
- Perhaps make use of upstream Trusted Firmware-A on supported SoCs
- Build BL21 and BL301 from source, where possible
- Test
Building BL21 and BL301 from source:
We would need the downstream u-boot tree of devices we support, as this is where the source is. Sadly, despite being under GPL, some manufacturers don't provide them (e.g. Videostrong) or only provide them privately (e.g. WeTek), possibly because of the amount of NDAs Amlogic makes them sign which may scare them into not sharing. It's also a whole mess even if we have all source trees, so perhaps also make some sort of tiny build system just for BL21/BL301?
Known downstream trees for devices:
- Amediatech X96 Mini: None
- JetHub J80 BL21/BL301/ACS is known to work: https://github.com/jethome-ru/amlogic-uboot/tree/jethome_v2015
- Beelink GT1 (Ultimate): None
- Might work with some other tree, but I don't own that box, so let's use prebuilts for now.
- Libre Computer AML-S905X-CC: https://github.com/libre-computer-project/libretech-amlogic-boot/
- Libre Computer AML-S805X-AC: https://github.com/libre-computer-project/libretech-amlogic-boot/
- Radxa Zero: https://gitlab.com/radxa_zero2/p-amlogic/uboot/-/tree/default?ref_type=heads ???
- Videostrong KII Pro: https://github.com/BayLibre/u-boot/tree/u-boot-amlogic ??? (TODO: Make something up)
Upstream Trusted Firmware-A:
Not all SoCs we support have a port upstream... Apart from that it should be doable easily for gxbb and gxl. Only g12a/b and sm1 will be challenging.
