[U-Boot] [PATCH] ids8313: Start DM/DT conversion
Mario Six
mario.six at gdsys.cc
Fri Jun 7 07:51:18 UTC 2019
This commit does the minimal possible conversion so that the ids8313
board still compiles with the recent SPI DM conversion:
* Add a device tree (for now a 1-to-1 copy of the mpc8313erdb board's DT
from the Linux kernel sources)
* Remove the legacy CS switching mechanism from the board file
* Enable enough config options to that the board compiles
