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.
