The Forlinx OKA40i-C devboard makes use of UARTs 0,2,3,4,5 and 7 of the R40 SoC, of which UART 0 is connected to an RS232 converter, UART 5 routed to an RS485 converter, and the rest broken out directly via labeled headers. The board also contains a micro-SD slot connected to SDC3. This patch adds settings to R40's pinmux node for those UARTs that were not already mapped, which would allow us to make use of all available UARTs and the micro-SD slot on this board in a further patch.

Looks alright, compared against the R40 manual. Reviewed-by: Andre Przywara <andre.przywara@arm.com> Cheers, Andre
