This adds the TPL support for the RK3368, including the u-boot-tpl.lds.
Signed-off-by: Philipp Tomsich philipp.tomsich@theobroma-systems.com
Changes in v2:
- copies the enum for the IOMUX config of the debug UART into the TPL support code, as the various constants are otherwise private to the pinctrl code (and we can't include pinctrl in the TPL stage due to size constraints/dependencies)

Can we not get this and other addresses from DT (or of-platdata)?
