[PATCH v2 0/2] ARM: ls1046a: add support for Arkona AT300

[Steffen Trumtrar]

This series adds support for a variant of the TQ tqmls1046a SoM.
The Arkona AT300 is based on the TQ SoM, with mainly different RAM and QSPI setup.

To help generating the RCW IO-muxing values, add a header and tool to
generate these values.

Changes in v2:
- enable barebox deep-probe in devicetree
- only add alternate qspi on AT300 board
- split rcwtool to scripts/include/ls1046a-rcwtool.h header
