Subject: [U-Boot] [PATCH 0/3] Fix hang when loading U-Boot from SPI or NAND
Date: Wed, 13 Apr 2011 13:07:35 -0700 [thread overview]
Message-ID: <1302725258-28539-1-git-send-email-twarren@nvidia.com> (raw)
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.
