[U-Boot] [PATCH 2/2] tegra: Whistler board support
Stephen Warren
swarren at wwwdotorg.org
Tue May 15 01:13:46 CEST 2012
From: Stephen Warren <swarren at nvidia.com>
Whistler is a highly configurable Tegra evaluation and development board.
This change adds support for the following specific configuration:
E1120 motherboard
E1108 CPU board
E1116 PMU board
The motherboard configuration switches are set as follows:
SW1=0 SW2=0 SW3=5
S1/S2/S3/S4 all on, except S3 7/8 are off.
Other combinations of daugher boards may work to varying degrees, but will
likely require some SW adjustment.
