From: Kumar Gala Date: Fri, 15 Aug 2008 13:24:37 +0000 (-0500) Subject: bootm: refactor ramdisk locating code X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=c4f9419c6b54958e0eddbcbc9e5a4a7b7ec99865;p=u-boot.git bootm: refactor ramdisk locating code Move determing if we have a ramdisk and where its located into the common code. Keep track of the ramdisk start and end in the bootm_headers_t image struct.
