Hi Tom,

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
Next time you post an updated patchset, please put patch history/changelog in the patches themselves.
I'll pull these in tomorrow morning unless someone requests changes in the meantime.
Amicalement,
