Subject: [PATCH] mtd cmdlinepart: allow zero offset value
X-Git-Tag: v2.6.17-rc1~136
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b175d03dd207283609b7f8bfdaa5dc93ac9b16dd;p=pandora-kernel.git

[PATCH] mtd cmdlinepart: allow zero offset value

Current cmdlinepart.c uses offset value 0 to specify a continuous
partition.  This prevents creating a second partition starting at 0.

For example, I can split 4MB device using "mtdparts=id:2M,2M", but I can
not do "mtdparts=id:2M@2M,2M@0" to swap mtd0 and mtd1.

This patch introduces special OFFSET_CONTINUOUS value for a continuous
partition and allows 0 for offset value.

Also this patch replaces 0xffffffff with UINT_MAX for SIZE_REMAINING.
