Subject: [PATCH v1 1/8] mtd: spi-nor: spansion: s25fl256s0: remove SKIP_SFDP flag
Date: Fri, 3 Jul 2026 16:29:12 +0200 [thread overview]
Message-ID: <20260703143003.1809579-2-mwalle@kernel.org> (raw)
In-Reply-To: <20260703143003.1809579-1-mwalle@kernel.org>
That flag was added in [1] to not "issue any non supported commands".
But since we now have the generic SFDP driver, we'll issue the RDSFDP
command on most flashes anyway and there was no single complaint. Remove
the only user of this flag so we can rework the parameter initialization
in the core.
