[U-Boot] [PATCH] da850/omap-l138: enable SPI flash in RMII mode

[Prabhakar Lad]

From: Rajashekhara, Sudhakar <sudhakar.raj at ti.com>

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.
