According to DA850/OMAP-L138 schematics, GP2[6] line has to be driven high for RMII mode to work. In RMII mode, SPI flash becomes un-usable. But during testing it was found out that, driving GP2[6] low also enables RMII and in this configuration SPI flash is also accessible.

How about just removing all the code that is related to GP2[6]? There's a pull-down resistor on the board and the pin is high impedance by default.

Yes, this patch is not required I'll drop this patch.

Thx, --Prabhakar Lad

Regards, Christian
