From acb3655973de30cb74549986e5e118a374967702 Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Mon, 23 Mar 2009 02:04:17 +0100 Subject: [ARM] pxa: Refactor Colibri board support code - Move common function for all Colibri PXA3xx boards to the newly added colibri-pxa3xx.c - Drop some unnecessary defines from colibri.h - Make Kconfig reflect the fact that code for colibri 300 module does also work for the 310 model - Give up on the huge pin config table which was messed up with lots of #ifdefs and switch over to locally defined tables for configured functions Cc: Matthias Meier Signed-off-by: Daniel Mack Signed-off-by: Eric Miao --- arch/arm/mach-pxa/colibri-pxa300.c | 116 ++++++++++++------------------------- 1 file changed, 36 insertions(+), 80 deletions(-) (limited to 'arch/arm/mach-pxa/colibri-pxa300.c') diff --git a/arch/arm/mach-pxa/colibri-pxa300.c b/arch/arm/mach-pxa/colibri-pxa300.c index a5c1f72d88c9..14ef9bf094fa 100644 --- a/arch/arm/mach-pxa/colibri-pxa300.c +++ b/arch/arm/mach-pxa/colibri-pxa300.c @@ -1,8 +1,10 @@ /* * arch/arm/mach-pxa/colibri-pxa300.c * - * Support for Toradex PXA300 based Colibri module + * Support for Toradex PXA300/310 based Colibri module + * * Daniel Mack + * Matthias Meier * * This program is free software;
