Subject: [PATCH] mtd: parsers: ofpart: make symbol 'bcm4908_partitions_quirks'
static
The sparse tool complains as follows:
drivers/mtd/parsers/ofpart_core.c:25:32: warning:
symbol 'bcm4908_partitions_quirks' was not declared. Should it be static?
This symbol is not used outside of ofpart_core.c, so this
commit marks it static.

+title: Linksys Northstar partitioning
+
+description: |
+ Linksys devices based on Broadcom Northstar architecture often use two
+ firmware partitions. One is used for regular booting, the other is treated as
+ fallback.
+
+ This binding allows defining all fixed partitions and marking those containing
+ firmware. System can use that information e.g. for booting or flashing
+ purposes.
