[PATCH 00/22] Add initial Texas Instruments K3 support

[Sascha Hauer]

This series adds initial basic support for the TI K3 Architecture.
Currently only the AM62x is supported and within there the BeaglePlay
board (https://www.beagleboard.org/boards/beagleplay).

The current support is enough for bringing up barebox 2nd stage after
U-Boot has initialized the SoC. The SoC boots from a FAT partition on
SD/eMMC, the u-boot.img therein can be replaced with a barebox image.

The SoC has a core dedicated to handle clocks, power domains and other
stuff. Communication to this core is done with a mailbox interface and
this series contains patches to implement that interface based on that
a clk driver and a power domain driver.

So far only SD/eMMC is working, so there's plenty of room to add further
support for networking, USB, SPI and I2C. It's a start.
