m68k: stmark2: use ioport.h macros for resources

2026-06-11T08:01:48+00:00

Change resource declaration using DEFINE_RES_*() macros.
DEFINE_DMA_RES() is for a single dma channel, not a range, so used twice.

Also, some drivers assume IRQ resources are from index 1, so just to stay
uniform, moved IRQ resource at index 1.

m68k: coldfire: use ColdFire specifc IO access in SoC code

2026-06-08T03:15:18+00:00

Convert all ColdFire specific SoC/board setup code to only use the
newly created internal register access methods. This is replacing the
mixed and inconsistent use of readx/writex and __raw_readx/__raw_writex
for internal SoC registers.

m68k: coldfire: rename timer register access defines

2026-06-08T03:15:18+00:00

With the basic ColdFire IO register functions now consistently named
with a "mcf_read"/"mcf_write" prefix it makes sense to name the timers
internal access defines the same way. Convert the local __raw_readtrr
and __raw_writetrr defines to use the consistent prefixes too. Thus
the change is:

    __raw_readtrr  --> mcf_readtrr
    __raw_writetrr --> mcf_writetrr
