From 8593790d604c29a717d5914159ce78c7bb9899fb Mon Sep 17 00:00:00 2001 From: "Mark A. Greer" Date: Wed, 3 Jun 2009 18:41:53 -0700 Subject: davinci: da8xx: Add support for DA830/OMAP-L137 EVM board Add support for the DA830/OMAP-L137 Evaluation Module (EVM) from TI. The EVM has User Interface (UI) and Audio cards that can be connected which contain various devices. Support for those devices and ones on the EVM will be added in subsequent patches. Additional generalizations for future SoCs in da8xx family done by Sudhakar Rajashekhara and Sekhar Nori. Signed-off-by: Steve Chen Signed-off-by: Mark A.
