* | ARM: shmobile: Consolidate SCU mapping codeGeert Uytterhoeven2016-02-171-2/+1
|/ | | | | | | | | | | | | | | | | | | | | | | Currently the SCU registers are mapped in SoC-specific code, using different methods, all involving the static mapping set up from machine_desc.map_io(): - On emev2, a static (non-identity) mapping is used, with ioremap(). As the static mapping uses the MT_DEVICE type, ioremap() reuses it, and the returned virtual address is suitable for passing to shmobile_smp_hook(), - On sh73a0 and r8a7779, a static identity mapping is used, with the legacy IOMEM() macro. As the static mapping uses the MT_DEVICE_NONSHARED type, replacing IOMEM() by ioremap() would create a new mapping, whose virtual address cannot be passed to shmobile_smp_hook(). Move the mapping of the SCU registers from SoC-specific code to common code, always using ioremap(). To work in the absence of a static mapping, this requires passing the physical SCU base address to shmobile_smp_hook().

* | arm: delete __cpuinit/__CPUINIT usage from all ARM usersPaul Gortmaker2013-07-141-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The __cpuinit type of throwaway sections might have made sense some time ago when RAM was more constrained, but now the savings do not offset the cost and complications. For example, the fix in commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time") is a good example of the nasty type of bugs that can be created with improper use of the various __init prefixes. After a discussion on LKML[1] it was decided that cpuinit should go the way of devinit and be phased out. Once all the users are gone, we can then finally remove the macros themselves from linux/init.h. Note that some harmless section mismatch warnings may result, since notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c) and are flagged as __cpuinit -- so if we remove the __cpuinit from the arch specific callers, we will also get section mismatch warnings. As an intermediate step, we intend to turn the linux/init.h cpuinit related content into no-ops as early as possible, since that will get rid of these warnings. In any case, they are temporary and harmless. This removes all the ARM uses of the __cpuinit macros from C code, and all __CPUINIT from assembly code. It also had two ".previous" section statements that were paired off against __CPUINIT (aka .section ".cpuinit.text") that also get removed here.

* mach-shmobile: Emma Mobile EV2 SMP support V3Magnus Damm2012-05-181-0/+97
This is V3 of Emma Mobile EV2 SMP support. At this point only the most basic form of SMP operation is supported. TWD and CPU Hotplug support is excluded. Tied to both the Emma Mobile EV2 and the KZM9D board due to the need to switch on board in platsmp.c and the newly introduced need for static mappings. The static mappings are needed to allow hardware acces early during boot when SMP is initialized. This early requirement forces us to also map in the SMU registers.
