Subject: [PATCH][RFC] mtd: bcm47xxpart: lower minimal blocksize to 4Ki (from
|
|
64Ki)

Some devices like Netgear WNR1000v3 or WGR614v10 have partitions aligned
|
|
to 0x1000. Using bigger blocksize stopped us from detecting some parts.

Most of supported devices use flashes with erasesize 0x10000 (64Ki), so
|
|
this change shouldn't affect them (no regressions expected).
|
|
Any objections?
