Subject: [PATCH] mtd: sf: Set SF parameters as env variables
Date: Tue, 14 Sep 2021 05:28:49 +0200	[thread overview]
Message-ID: <20210914032849.273625-1-marex@denx.de> (raw)

Set the SF page size, erase block size and total size as an environment
variable after "sf probe". This lets us discern boards with multiple
distinct SPI flash options and also e.g. set mtdparts accordingly.
