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.
