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).

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.

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.

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.

m68knommu: make 5249 QSPI platform addressing consistent

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

If we make all QSPI (SPI protocol) addressing consistent across all ColdFire
family members then we will be able to remove the duplicated plaform data
and code and use a single setup for all.

So modify the ColdFire 5249 QSPI addressing so that:

. base addresses are absolute (not relative to MBAR peripheral register)
. use a common name for IRQs used
. move chip select definitions (CS) to appropriate header

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.

The ColdFire UART is common to all ColdFire CPU's. No need to duplicate

m68knommu: simplify the 5249 UART setup code

2012-03-04T23:43:06+00:00

Simplify the UART setup code so that it no longer loops for each UART
present. Just make it do all the work it needs in a single function.
This will make the code easier to share when we move to a single set
of platform data for ColdFire UARTs.

m68knommu: make 5249 UART platform addressing consistent

2012-03-04T23:43:05+00:00

If we make all UART addressing consistent across all ColdFire family members
then we will be able to remove the duplicated plaform data and use a single
setup for all.

So modify the ColdFire 5249 UART addressing so that:

. UARTs are numbered from 0 up
. base addresses are absolute (not relative to MBAR peripheral register)
. use a common name for IRQs used

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.
