From: Ron Madrid Date: Thu, 22 Jan 2009 23:05:24 +0000 (-0800) Subject: mpc83xx: New board support for SIMPC8313 X-Git-Tag: v2009.03-rc1~173^2^2 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=5bb907a4925397789c90d074f4f7e92ce6b39402;p=u-boot mpc83xx: New board support for SIMPC8313 This patch will create a new board, SIMPC8313, from Sheldon Instruments. This board boots from NAND devices and is configureable for either large or small page devices. The board supports non-soldered DDR2, one ethernet port, a Marvell 88E1118 PHY, and PCI host support. The board also has a FPGA connected to the eLBC providing glue logic to a TMS320C67xx DSP.
