From: Kumar Gala Date: Sat, 30 Aug 2008 00:08:29 +0000 (-0500) Subject: Prevent crash if random/invalid ramdisks are passed to bootm X-Git-Tag: v2008.10-rc1~48 X-Git-Url: https://git.kernelconcepts.de/?a=commitdiff_plain;h=ea86b9e64b811753d9eabe0f560ee189fbe5d0c1;p=karo-tx-uboot.git Prevent crash if random/invalid ramdisks are passed to bootm Adds returning an error from the ramdisk detection code if its not a real ramdisk (invalid). There is no reason we can't just return back to the console if we detect an invalid ramdisk or CRC error.
