[PATCH v2] ARM: imx: add support for TQMa6UL SoM on MBa6ulxl
Rouven Czerwinski
r.czerwinski at pengutronix.de
Thu Jun 17 02:23:05 PDT 2021
Add support for a TQMA6UL2L SoM on top of a MBa6ulxl baseboard. The
imxcfg header is for the LGA variant, the downstream U-Boot has an ifdef
for another "standard" variant, however this is not included here since
I don't have hardware to test.
Signed-off-by: Rouven Czerwinski <r.czerwinski at pengutronix.de>
---
v1->v2:
- split up barebox and kernel dts
- fixed DEBUG_LL
- removed mmc0/1 alias switch
- add environment handling
- add MAC handling
- add default update handler
