[U-Boot] [PATCH v2 19/20] tegra: fdt: Add EMC data for Tegra2 Seaboard

Simon Glass sjg at chromium.org
Fri Jan 13 22:35:34 CET 2012


This adds timings for T20 and T25 Seaboards, using the bindings found here:

http://patchwork.ozlabs.org/patch/132928/

We supply both full speed options for normal running, and half speed options
for testing / development.
