From: Peter Barada Date: Mon, 19 Dec 2011 19:54:51 +0000 (+0000) Subject: ARMV7: Add support For Logic OMAP35x/DM37x modules X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=86887f8ea189a6c23a1563e940957281374c9405;p=u-boot.git ARMV7: Add support For Logic OMAP35x/DM37x modules This patch adds basic support for OMAP35x/DM37x SOM LV/Torpedo reference boards. It assumes U-boot is loaded to SDRAM with the help of another small bootloader (x-load) running from SRAM.
