2013-04-03ARM: tegra: moving the CPU power timer function to PMC driverJoseph Lo
The CPU power timer set up function was related to PMC register. Now moving it to PMC driver. And it also help to clean up the PM related code later. The timer was calculated based on the input clock of PMC. In this patch, we also get the clock from DT.

2013-03-11ARM: tegra: refactor tegra{20,30}_boot_secondaryHiroshi Doyu
"tegra_boot_secondary()" has many condition branches for some Tegra SoC generations in a single function so that it's not easy to compile a kernel only for a single SoC if one wants with some reason, debug purpose(?). This patch provides SoC specific version of boot_secondary(), tegra{20,30}_boot_secondary(). This could allow any combination of SoC to be built. Those boot_secondary functions can be preparation when we ntroduce chip specific function pointers in the future without having chip dependent branches around.

2013-03-11ARM: tegra: don't unlock MMIO access to DBGLARJoseph Lo
There is no need to unlock MMIO access to the DBGLAR all the time. Doing so may even cause problems if a SW bug causes writes to that MMIO region. Cortex-A15 processors do not support the CP14 register write the code currently uses to unlock the DBGLAR; the instruction throws an undefined instruction exceptions. This prevents tegra_secondary_startup() from executing on Tegra114, and hence prevents SMP. Remove the code that unlocks this access.

2013-03-11ARM: tegra: remove save/restore of CPU diag registerStephen Warren
Prior to this change, {save,restore}_cpu_arch_register() collaborated to maintain the value of the CPU diagnostic register across power cycles. This was required to maintain any CPU errata workaround enable bits in that register. However, now that the Tegra reset vector code always enables all required workarounds, there is no need to save and restore the diagnostic register; it is always explicitly programmed in the required manner. Hence, remove the save/restore logic. This has the advantage that the kernel always directly controls the value of this register every boot, rather than relying on a bootloader or other kernel code having previously written the correct value into it. This makes CPU0 (which was previously saved/restored) and CPUn (which should have been set up by the reset vector) be controlled in exactly the same way, which is easier to debug/find/... In particular, when converting Tegra to a multi-platform kernel, the CPU0 diagnostic register value initially comes from the bootloader. Most Tegra bootloaders don't yet enable all required CPU bug workarounds. The previous commit updates the kernel to do so on any CPU power cycle. However, the save/restore code ends up over-writing the value with the old bootloader-driven value instead of the now more-likely-to-be-correct kernel value! Even irrespective of multi-platform conversion, this change limits the kernel's exposure to any WARs the bootloader didn't enable for CPU0: on the very first LP2 transition (CPU power-saving which power-cycles the CPU), the correct value will be enabled. Signed-off-by: Stephen Warren <swarren@nvidia.com>
2013-03-11ARM: tegra: add CPU errata WARs to Tegra reset handlerStephen Warren
The CPU cores in Tegra contain some errata. Workarounds must be applied for these every time a CPU boots. Implement those workarounds directly in the Tegra-specific CPU reset vector. Many of these workarounds duplicate code in the core ARM kernel. However, the core ARM kernel cannot enable those workarounds when building a multi-platform kernel, since they require writing to secure- only registers, and a multi-platform kernel often does not run in secure mode, and also cannot generically/architecturally detect whether it is running in secure mode, and hence cannot either unconditionally or conditionally apply these workarounds. Instead, the workarounds must be applied in architecture-specific reset code, which is able to have more direct knowledge of the secure/normal state. On Tegra, we will be able to detect this using a non-architected register in the future, although we currently assume the kernel runs only in secure mode. Other SoCs may never run the kernel in secure mode, and hence always rely on a secure monitor to enable the workarounds, and hence never implement them in the kernel.

Commit 0cc41e4a21d43 (arch: remove direct definitions of KERN_<LEVEL> uses) is broken - not enough thought was put into changing: .asciz "string" to .asciz "string1" "string2" The problem is that each string gets _separately_ NUL terminated, so the result is a string containing: "string1\0string2\0" rather than: "string1string2\0" With our new printk levels, this ends up as - eg, KERN_DEBUG "string": 0x01 0x00 0x07 0x00 "string" 0x00 which produces lots of \x01 in the kernel log.

Notable changes are: - More devices get moved out of board files into device tree descriptions. The remaining devices listed in there have patches that will get sent for 3.10, after which we can remove a lot of the board files entirely. We are doing the pinctrl and mmc drivers here, ethernet and PCI still remain. - SMP support for mvebu is improved with support for the local interrupt controller. - The Guruplug board file gets replaced with a DT description. Unfortunately, the dependency on the MMC tree turned out to be a much larger problem than expected, when the MMC maintainer rebased the patches in his tree that all of the patches in this branch are based on, which caused merge conflicts between the new and old versions of those patches. To work around the merge conflicts, this branch rebases all patches on top of the respective MMC patches that did get merged into 3.9. The patches are all identical to the versions that were part of linux-next, but have a new commit date." * tag 'late-mvebu-rebased' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (90 commits) arm: mvebu: enable the SD card slot on Armada 370 Reference Design board ARM: kirkwood: topkick: init mvsdio via DT ARM: kirkwood: nsa310: convert to pinctrl ARM: Kirkwood: topkick: Enable i2c bus.
