Subject: [PATCH 0/2] mtd: rawnand: vf610_nfc: fix the OOB of written pages and the command completion
Date: Fri, 28 Aug 2026 10:53:38 +0200	[thread overview]
Message-ID: <20260828085340.3916239-1-mehmet.fide@gmail.com> (raw)

From: Mehmet Fide <mehmet.fide@screeningeagle.com>

Two pre-existing issues found while checking the Sashiko report Miquel
pointed at on the large-OOB series [1]; they are independent of that
fix, so they come separately.

The first has been there since the ->exec_op() conversion: the ECC page
write transfers the spare area out of the controller SRAM but nothing
ever puts chip->oob_poi there, so every written page gets whatever the
previous transfer left behind as its OOB. The second is as old as the
driver: a command that timed out can still complete cmd_done from its
late interrupt, and the next command then returns before the hardware
is done.

Tested on a Colibri VF50 and a Colibri VF61 on top of the large-OOB v2
series: UBIFS write/read-back intact, clean ECC counters.
