mtd: remove the warning about read-only caused by size vs. block boundary mismatch
Since the kernel/rootfs split handling was modified 2 years ago by r37283 ( https://dev.openwrt.org/changeset/37283 ) and by the subsequent checkins, users have seen rather scary mtd errors in the log at every boot. The message ends "-- forcing read-only", which looks a bit error-like. That error has been mentioned in some forum threads, when users have noticed this message instead of some actual error. [ 2.940000] 0x000000070000-0x000000ff0000 : "firmware" [ 2.970000] 2 netgear-fw partitions found on MTD device firmware [ 2.970000] 0x000000070000-0x000000188440 : "kernel" [ 2.980000] mtd: partition "kernel" must either start or end on erase block boundary or be smaller than an erase block -- forcing read-only [ 2.990000] 0x000000188440-0x000000ff0000 : "rootfs" The patch removes the rather useless warning message. signed-off-by: Hannu Nyman <hannu.nyman@iki.fi> SVN-Revision: 45669
