+Subject: [PATCH v5 6/9] ARM: pxa/corgi: Remove hardcoded partitioning, use
+ sharpslpart parser
+
+With the introduction of sharpslpart partition parser we can now read the
+offsets from NAND: we specify the list of the parsers as platform data, with
+cmdlinepart and ofpart parsers first allowing to override the part. table
+written in NAND. This is done here in the board file.
