> corrects a UARTD bit error in clk_rst.h, and adds rudimentary GPIO
> support so that the UART on Seaboard can be used by U-Boot (UARTD&
> SPIFLASH are muxed, and the default POR setting is for SPI access, so
> GPIO_PI3 has to be driven low to enable serial console I/O over UARTD).
> Harmony has no SPIFLASH, so the issue doesn't exist there.

Applied in u-boot-arm/master, thanks.
