2012-05-12gpio/mxs: get rid of the use of cpu_is_xxxShawn Guo
It removes the use of cpu_is_xxx from gpio-mxs driver and instead use platform_device_id to identify the device. Accordingly, mxs platform code is changed to register gpio device with different names, and the registeration are done in soc specific initialization functions now, so postcore_initcall(mxs_add_mxs_gpio) gets removed.

2012-05-12ARM: mxs: do not add dma device by defaultDong Aisheng
This will cause conflict when dt is enabled. So let each platform add dma devices respectively.

We used to runtime patch the trap table for srmmu. With the removal of sun4c support this is no longer required. With the sun4c trap removed we can remove all the referenced trap handling which is sun4c specific. This also allows us to get rid of the nosun4c.c file that contained only dummy functions/data.

2012-05-11sparc32: drop sun4c supportSam Ravnborg
Machines with sun4c support are very rare these days, and noone is using them for any practical purposes. The sun4c support has been know broken for quite some time too. So rather than trying to keep it up-to-date, lets get rid of it. This allows us to do some very welcome cleanup of sparc32 support. Updated the former sun4c specifc nmi (which was also used for sun4m UP) to be a generic UP NMI. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
