Subject: [PATCH v3 0/3] mtd: cfi_cmdset_0002: Use chip_ready() for write on S29GL064N
Date: Wed, 16 Mar 2022 01:56:04 +0900	[thread overview]
Message-ID: <> (raw)

As pointed out by this bug report [1], the buffered write is now broken on
S29GL064N. The reason is that changed the buffered write to use chip_good
instead of chip_ready. One way to solve the issue is to revert the change
partially to use chip_ready for S29GL064N since the way of least surprise.
