The AM62L is a new SoC from TI similar to the AM625, but still needs
some work to support it.
While the peripherals are quite similar to AM625, TI restructured the
startup process. Unlike the AM625 we no longer start on the Cortex-R5
core, but instead directly on the first Cortex A53 core. The SDRAM setup
is no longer part of barebox, but instead done in the TF-A. The initial
image is composed of a BL1 and several binary-only blobs. The second
stage is directly the BL31 image and our barebox image.
The dts(i) are not yet upstream, but currently posted for review, so we
need to import them into barebox for now. I hope this will be obsolete
soon.
The DMA driver needs some adjustments for the AM62L, patches for this
are taken from the TI downstrem U-Boot and the TI downstream Linux
repository.
The first board supported is the AM62L EVM board.
