Subject: Re: Fixes to MTD flash driver on AMD Alchemy db1100 board
Date: Mon, 21 Feb 2005 23:25:42 -0800 [thread overview]
Message-ID: <421ADE76.5020905@embeddedalley.com> (raw)

Here is a 2.6 patch that gets rid of all the Au1x mapping files and
replaces them with a single file. The driver doesn't check for
different flash densities supported by the Db1x boards, but it
turns out AMD always shipped the boards with a single configuration
only. This file should work on all boards. And I think it should
work with 2.4 as well, as long as the entire tree is patched.
Though, I need to first update the 2.4 style Config.in in the mtd tree.
