ARM: tegra: build assembly files with -march=armv7-a The tegra assembly files are written for ARMv7 and are not compatible with ARMv6, which leads to build warnings when compiling a dual ARMv6/v7 kernel. Since this code is only ever run on Tegra ARMv7 hardware, we can tell the assembler which architecture level to use. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

ARM: tegra30: cpuidle: add powered-down state for secondary CPUs This supports power-gated idle on secondary CPUs for Tegra30. The secondary CPUs can go into powered-down state independently. When CPU goes into this state, it saves it's contexts and puts itself to flow controlled WFI state. After that, it will been power gated. Be aware of that, you may see the legacy power state "LP2" in the code which is exactly the same meaning of "CPU power down".

ARM: tegra: make device can run on UP The reset handler code is used for either UP or SMP. To make Tegra device can compile for UP. It needs to be moved to another file that is not SMP only. This is because the reset handler also be needed by CPU idle "powered-down" mode. So we also need to put the reset handler init function in non-SMP only and init them always. And currently the implementation of the reset handler to know which CPU is OK to bring up was identital with "cpu_present_mask". But the "cpu_present_mask" did not initialize yet when the reset handler init function was moved to init early function. We use the "cpu_possible_mask" to replace "cpu_present_mask". Then it can work on both UP and SMP case.

And the PLLs need to be re-enabled, SCLK burst policy be restored, CCLK burst policy be set in PLLP.

ARM: v7 setup function should invalidate L1 cache All ARMv5 and older CPUs invalidate their caches in the early assembly setup function, prior to enabling the MMU. This is because the L1 cache should not contain any data relevant to the execution of the kernel at this point; all data should have been flushed out to memory. This requirement should also be true for ARMv6 and ARMv7 CPUs - indeed, these typically do not search their caches when caching is disabled (as it needs to be when the MMU is disabled) so this change should be safe. ARMv7 allows there to be CPUs which search their caches while caching is disabled, and it's permitted that the cache is uninitialised at boot; for these, the architecture reference manual requires that an implementation specific code sequence is used immediately after reset to ensure that the cache is placed into a sane state. Such functionality is definitely outside the remit of the Linux kernel, and must be done by the SoC's firmware before _any_ CPU gets to the Linux kernel. Changing the data cache clean+invalidate to a mere invalidate allows us to get rid of a lot of platform specific hacks around this issue for their secondary CPU bringup paths - some of which were buggy.

ARM: tegra: remove board (but not DT) support for Paz00 Paz00 (Toshiba AC100) can be booted using device tree with equal functionality as when booted using a board file. Remove as much of the board file as is possible, since it's no longer needed. One special-case is still left in board-dt-tegra20.c, since there is no way to create a WiFi rfkill device from device tree yet. This logic is now enabled unconditionally rather than via CONFIG_MACH_PAZ00. The extra cases where it's enabled (.configs which did not enable Paz00 support) shouldn't impact much since the amount of code is tiny.
