From 069e1f02815874f9c825f110c9dad63848c55638 Mon Sep 17 00:00:00 2001

Subject: [PATCH v5 9/9] ARM: pxa/poodle: 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.
