Cover letter [PATCH v4 0/2] ARM: shmobile: Add early debugging support using SCIF(A)

Hi Simon, Magnus, Arnd,
This patch series adds serial port debug macros for the SCIF(A) serial ports. This includes all supported shmobile SoCs, except for EMEV2.
It contains 2 patches, which are two alternative versions:
- The first patch keeps on using the identity mapping set up by .map_io() on platforms I cannot test myself (sh7372 and r8a7779),
- The second one converts the remaining platforms to usedebug_ll_io_init(), which allowed to get rid of the #ifdef inrenesas-scif.S, and consolidate more config options.Both versions work fine on r8a7791/koelsch (multiplatform), r8a7740/armadillo (legacy and reference), and sh73a0/kzm9g (legacy, reference, and multiplatform), also with a multiplatform kernel based on
shmobile_defconfig.

I'd appreciate if you could test the second one on sh7372 and r8a7779, and if it works, apply it.
Else, please apply the first version. We can do incremental conversions later, as discussed before.
Both versions look good to me,
I do notice that strictly speaking you break alphabetical ordering by putting DEBUG_R8A* and DEBUG_RCAR* after DEBUG_RK*, but it does seem way more reasonable like this.
