[PATCH v2 0/1] fw_env: auto-detect NAND characteristics

[Anthony Loiseau]

From: Anthony Loiseau <anthony.loiseau at allcircuits.com>

Hello,

Here is a patch proposal which modifies fw_env so NAND chip erase size as well
as environment sector counts are guessed at runtime if they are both statically
configured as zero.
This actually extends a previous similar behavior which was NOR-specific,
useful when a same RootFS is executed with several flash chips,
see e282c422e0b.

Be aware that I did not test this exact patch for real. I extracted it from
my older u-boot-flsc 2016 tree on which it works well, and built it using
a sandbox configuration, without running it. I only checked my gcc was happy
with those lines (no warnings added). My feeling is that this patch is small
enough to feel confident it will work on master as it worked on my old tree.


Opened to any reviews or requests,
best rergards,
Anthony Loiseau
