Subject: [RFC PATCH 0/2] env: sf: remove the static env_flash variable
Date: Wed, 24 Feb 2021 11:52:34 +0100	[thread overview]
Message-ID: <20210224105236.25663-1-patrick.delaunay@foss.st.com> (raw)

Proposal to cleanup the SPI device support in env/sf.c,
after the question of mail [1].

Release the SPI flash after each ENV request, so U-Boot can't have
conflict of other SPI user.

This serie can be applied on top on previous serie [2].

Drawback: possible performance issue as SPI device is probed/release
for each ENV access when several ENV opts are called.
