ARM: exynos: move debug-macro.S to include/debug/ The move is necessary to support early debug output on exynos with multiplatform configurations. This implies also moving the plat/debug-macro.S file, but we are leaving the remaining users of that file in place, to avoid adding large numbers of extra configuration options to Kconfig.debug Signed-off-by: Arnd Bergmann <arnd@arndb.de>

ARM: EXYNOS4: Add EXYNOS4 CPU initialization support This patch adds EXYNOS4 CPU support files in mach-exynos4, and basically they are moved from mach-s5pv310 so that it can support Samsung's new CPU name, EXYNOS4. The EXYNOS4 ingegrates a ARM Cortex A9 multi-core. Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

ARM: add an extra temp register to the low level debugging addruart macro Some platforms (like OMAP not to name it) are doing rather complicated hacks just to determine the base UART address to use. Let's give their addruart macro some slack by providing an extra work register which will allow for much needed cleanups. This is basically a no-op as this commit is only adding the extra argument to the macro but no one is using it yet.

ARM: EXYNOS: fix CONFIG_DEBUG_LL addruart cannot read from the physical address of the chipid register, that will fail as soon as the mmu is turned on. Fixing it to read from the physical or virtual address depending on the mmu state also does not work, because there is a period between head.S and exynos_map_io where the mmu is on, the uart is mapped and used, but the chipid mapping is not yet present. Fix addruart to use the ARM Main ID cp15 register to determine if the core is Cortex A15 (EXYNOS5) or not (EXYNOS4).

ARM: EXYNOS: Fix UART address selection for DEBUG_LL The Exynos542x SoCs using A15+A7 can boot to A15 or A7. If it boots using A7 (like on Odroid XU family boards), it can't choose right UART physical address only the part number of CP15. Fix the detection logic by checking the Cluster ID additionally.

arm: return both physical and virtual addresses from addruart Rather than checking the MMU status in every instance of addruart, do it once in kernel/debug.S, and change the existing addruart macros to return both physical and virtual addresses. The main debug code can then select the appropriate address to use. This will also allow us to retreive the address of a uart for the MMU state that we're not current in.
