ARM: mach-shmobile: r8a7779 and Marzen base support V2 Initial support for the r8a7779 SoC and the Marzen board (V2). Only SCIF ports and the TMU are supported at this point. To keep things simple only entity-mapped virt-to-phys mappings are supported. This forces drivers and other SoC glue code to make use of ioremap(). We cannot support early serial console due to virtual address space collisions with the ARM kernel. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

ARM: mach-shmobile: r8a7779 power domain support V2 Add power domain control support for the r8a7779 SoC V2. This adds support for 4 power domains for I/O Devices together with code that can be used for CPU cores as well. The only out of the ordinary experience is the need for ioremap() of SYSC registers. Because of that we need to execute some init function before setting up the domains. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

extern void r8a7779_pm_init(void);
ARM: mach-shmobile: r8a7779 SMP support V3 This patch contains r8a7779 SMP support V3 - now including CPU hotplug offine and online support. The r8a7779 power domain code is tied together with SMP glue code which allows us to control the power domains via CPU hotplug. At this point the kernel boots with the 4 Cortex-A9 cores in SMP mode and all CPU cores except CPU0 can be hotplugged. The code in platsmp.c is quite far from pretty, but it is kept like that intentionally to avoid creating layers of code that will go away in the near future anyway. The code needs to be updated when some per-SoC handling code will be added to the ARM architecture, see the following patch for more information: "[RFC PATCH 0/3] Per SoC descriptor" Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
