Subject: [U-Boot] Cache function change breaks zmx25
Date: Fri, 09 Dec 2011 15:24:56 +0100	[thread overview]
Message-ID: <4EE21A38.2070908@arcor.de> (raw)

Hi

commit 2f3427ccb915c6f6774f0bcebb67c648dc25dcfd
Author: Ilya Yanok <yanok@emcraft.com>
Date:   Mon Nov 28 06:37:32 2011 +0000

     arm926ejs: add noop implementation for dcache ops

breaks zmx25 booting with the following command:

tftpboot 0x82000000 foo.img; dcache on; bootm 0x82000000

It is stuck then in an endless loop after dcache is disabled before 
jumping to the OS.

------------------------------------------------
WARNING: cache operations are not implemented!
WARNING: disabling D-Cache now, you can re-enable itlater with 'dcache 
on' command
------------------------------------------------

Switching on dcache after the tftp worked without problems until this 
patch. I think this should be fixed before the release as it may have 
effects on other boards doing similar things.

Matthias
