ARM: shmobile: r8a7740: Remove legacy machine_desc.map_io() callback Commit 37201ba5c99d0be8 ("ARM: shmobile: r8a7740: Migrate to generic l2c OF initialization") removed the last user of the legacy "IOMEM()" macro on r8a7740-based systems. Hence there's no longer a need to set up a transparent mapping of system I/O registers. Remove the mapping and the legacy machine_desc.map_io() callback.

ARM: shmobile: r8a7740: Instantiate GIC from C board code in legacy builds As of commit 9a1091ef0017c40a ("irqchip: gic: Support hierarchy irq domain."), armadillo-legacy hangs during boot with: sh-tmu.0: ch0: used for clock events sh-tmu.0: ch0: used for periodic clock events sh-tmu.0: ch0: failed to request irq 230 sh-tmu.0: ch1: used as clock source sh-cmt-48.1: ch0: failed to request irq 90 sh-cmt-48.1: ch0: registration failed earlytimer: unable to probe sh-cmt-48 early. Calibrating delay loop... This happens because the IRQ numbers of the GIC are now virtual, and no longer match the hardcoded hardware IRQ numbers in the platform board code.

ARM: shmobile: Add early debugging support using SCIF(A) Add serial port debug macros for the SCIF(A) serial ports. This includes all supported shmobile SoCs, except for EMEV2. The configuration logic (both Kconfig and #ifdef) is more complicated than one would expect, for several reasons: 1. Not all SoCs have the same serial devices, and they're not always at the same addresses. 2. There are two different types: SCIF and SCIFA. Fortunately they can easily be distinguished by physical address. 3. Not all boards use the same serial port for the console. The defaults correspond to the boards that are supported in mainline. If you want to use a different serial port, just change the value of CONFIG_DEBUG_UART_PHYS, and the rest will auto-adapt. 4. debug_ll_io_init() maps the SCIF(A) registers to a fixed virtual address. 0xfdxxxxxx was chosen, as it should lie below VMALLOC_END = 0xff000000, and must not conflict with the 2 MiB reserved region at PCI_IO_VIRT_BASE = 0xfee00000. - On SoCs not using the legacy machine_desc.map_io(), debug_ll_io_init() is called by the ARM core code. - On SoCs using the legacy machine_desc.map_io(), debug_ll_io_init() must be called explicitly. Calls are added for r8a7740, r8a7779, sh7372, and sh73a0. This was derived from the r8a7790 version by Laurent Pinchart.
