From: Timur Tabi Date: Tue, 3 May 2011 18:35:11 +0000 (-0500) Subject: fman: insert the Fman firmware into the device tree X-Git-Tag: v2011.09-rc1~215 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=ffadc441bc993ed60ea473d248a115136f24932d;p=u-boot fman: insert the Fman firmware into the device tree The Fman device tree node binding allows for the entire Fman firmware binary data to be embedded in the device tree. This eliminates the need to have NOR flash mapped to Linux just so that the Fman driver can see the firmware. The location of the Fman firmware is taken from the 'fman_ucode' environment variable.
