From db5432db81b1775f145945b21428490583ab3e2b Mon Sep 17 00:00:00 2001 From: Ladislav Michl Date: Mon, 23 Nov 2009 00:06:50 +0100 Subject: [PATCH] mtd: fix M29W800D dev_id and uaddr This one sits in my tree for more than two years... Using device code found on page 12 (http://www.btdesigner.com/pdfs/M29W800D.pdf) and unlock address from page 15 MTD subsytem happily detects ST M29W800DB in 16-bit mode. I do believe original author used only 8-bit mode and thus didn't hit this bug.
