Currently only S3C6410 processors are supported, though addition of another data table with supported clock rates should be sufficient to enable support for further CPUs. Use the regulator framework to provide optional support for DVFS in the S3C cpufreq driver. When a software controllable regulator is configured the driver will use it to lower the supply voltage when running at a lower frequency, giving improved power savings. When regulator support is disabled or no regulator can be obtained for VDDARM the driver will fall back to scaling only the frequency.

Much of the code is based on Harald Welte's work, although it has been largely rewritten several times. This is intended to be the minimum machine definition to boot and be able to run a rootfs from NAND on GTA02 / FreeRunner. It does not bring up the framebuffer / Glamo and lacks many other peripheral drivers from outside the SoC. But once we have this basis in mainline kernel, we will be able to introduce the other drivers and add them here. Thanks to Sven Rebhan for his fixes to this patch (Kconfig and defconfig files).

The patch also fixes a bug in the unwind instructions interpreter. The 0xb0 instruction can only set PC to LR if this wasn't already set by a previous instruction (this is used on exceptions taken while in kernel mode where svc_entry is annotated with ".save {r0 - pc}").

Without this delay, the system is prone to random panics upon re-entering SDRAM. This time delay varies based on MPU frequency. At 500MHz MPU frequency at room temperature, 64 loops seems to work okay; so add another 32 loops for environmental and process variation.

Arrange for ARM to follow x86's lead on this and call pm_idle() with interrupts already disabled. However, we expect pm_idle() to enable interrupts before it returns. Also, OMAP wants to be able to disable hlt-ing, so allow hlt_counter to prevent all calls to pm_idle.
