-Subject: [PATCH][RFC] mtd: bcm47xxpart: lower minimal blocksize to 4Ki (from
- 64Ki)
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Some devices like Netgear WNR1000v3 or WGR614v10 have partitions aligned
-to 0x1000. Using bigger blocksize stopped us from detecting some parts.
-
-Signed-off-by: Rafał Miłecki <zajec5@gmail.com>
----
-Most of supported devices use flashes with erasesize 0x10000 (64Ki), so
-this change shouldn't affect them (no regressions expected).
-Any objections?
