[U-Boot] [PATCH 0/8] tegra2: Implement SPI flash and saved environment

[Simon Glass]

Enable SPI flash on the Tegra2 Seaboard along with a saved 8KB environment.
This involves a few pieces:

- Tegra2 SPI driver
- Seaboard config changes
- a SPI / UART switch to handle switching between SPI and console UART

This series applies cleanly on top of Stephen Warren's latest patch series

http://patchwork.ozlabs.org/patch/119325/

and also requires Stephen's GPIO fix.

Still to come are the NS16550 driver changes to cope with the pins
disappearing from under it. This patch series is under review.
