Subject: [PATCH] fix for mtd partitions for erase_size != 2^X
Date: Fri, 23 Sep 2005 12:05:13 +0200 [thread overview]
Message-ID: <20050923100513.26965.qmail@mw-itcon.de> (raw)
[-- Attachment #1: Type: text/plain, Size: 147 bytes --]
Here a trivial patch,
which allows correct creation of mtd partitions, which have erase sizes
which are not a power of 2.
Best regards
Peter
