m68knommu: enable qspi support when SPI_COLDFIRE_QSPI = m

2012-05-08T03:06:51+00:00

Enable Coldfire QSPI support when SPI_COLDFIRE_QSPI is built as a module. This version of the patch combines changes to the config files and device.c and uses IF_ENABLED (thanks to Sam Ravnborg for the suggestion). Signed-off-by: Steven King Signed-off-by: Greg Ungerer

m68knommu: fix id number for second eth device on 5275 ColdFire

2012-04-17T06:58:35+00:00

The second ColdFire FEC ethernet device should have an id number of 1, not 0. Otherwise it clashes with the first FEC ethernet device. On booting a kernel on a 5275 based board you will get messages out of the kernel like this: <4>------------[ cut here ]------------ <4>WARNING: at fs/sysfs/dir.c:508 0x0a8b50() <4>sysfs: cannot create duplicate filename 'fec.0' And likely you won't be able to completely boot up after this at all.

m68knommu: factor more common ColdFire cpu reset code

2012-03-05T00:42:28+00:00

Most of the more modern ColdFire cores use the same code to reset the CPU (but it is different to most of the earlier cores). Currently that is duplicated in each of the sub-arch files. Pull out this common code and out a single copy of it with the other common reset code. Signed-off-by: Greg Ungerer

m68knommu: factor some common ColdFire cpu reset code

2012-03-05T00:41:48+00:00

A number of the early ColdFire cores use the same code to reset the CPU. Currently that is duplicated in each of the sub-arch files. Pull out this common code and use a single copy of it for all CPU types that use it. Signed-off-by: Greg Ungerer

m68knommu: move old ColdFire timers init from CPU init to timers code

2012-03-04T23:43:10+00:00

The original ColdFire timer interrupt setup is used by most of the users of the original ColdFire timer code. But the code is currently duplicated in each of the ColdFire CPU specific init files. Move it to the timers code that it is really part of. It is strait forward to make it conditional on also having the original interrupt engine that it needs. Signed-off-by: Greg Ungerer

m68knommu: merge common ColdFire QSPI platform setup code

2012-03-04T23:43:09+00:00

The ColdFire QSPI is common to quite a few ColdFire CPUs. No need to duplicate its platform setup code for every CPU family member that has it. Merge all the setup code into a single shared file. This also results in few platforms no longer needing any local platform setup code. In those cases remove the empty devices array and initcall code as well. Signed-off-by: Greg Ungerer

m68knommu: merge common ColdFire UART IRQ setup

2012-03-04T23:43:08+00:00

Some ColdFire CPU UART hardware modules can configure the IRQ they use. Currently the same setup code is duplicated in the init code for each of these ColdFire CPUs. Merge all this code to a single instance. Signed-off-by: Greg Ungerer

m68knommu: modify timer init code to make it consistent with m68k code

2012-03-04T23:43:04+00:00

With a few small changes we can make the m68knommu timer init code the same as the m68k code. By using the mach_sched_init function pointer and reworking the current timer initializers to keep track of the common m68k timer_interrupt() handler we end up with almost identical code for m68knommu. This will allow us to more easily merge the mmu and non-mmu m68k time.c in future patches. Signed-off-by: Greg Ungerer
