Hi Tom,
Le 15/04/2011 00:09, Tom Warren a ?crit :
> This series of patches fixes a hang seen when loading U-Boot from SPI
> or NAND on Seaboard and Harmony due to a missing PLLX init. It also
> 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.
>
> With these changes, I can write U-Boot to SPI on Seaboard and boot with
> it to the U-Boot cmd prompt. This should also apply to loading from NAND
> on Seaboard and Harmony - testing to follow.

> Changes in V2:
> - Change 2nd patch's description to 'Add basic GPIO definitions'
> - Add more descriptive comment for CPCON use in init_pllx

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