From fcb28d2e9db7f1fc146a6e95200f166a86224066 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 13 Aug 2012 10:11:15 +0200 Subject: ARM: u300: retire ancient platforms This retires the B26/S26, B330/S330 and B365/S365 boards from the U300 platform. The only board really used anywhere today is the S335 so let's concentrate any efforts on that one board. Also the board variants are selected at compile-time, which is strictly a no-no these days, if multi-board support is to be brought back it need to happen using run-time and device tree. My work on ARM Linux started on the B26/S26 so it's a bit sad to see it go, but there is a time to move on with all things in life.
