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, -- Albert.
