ARM: mvebu: make sure MMU is disabled in armada_370_xp_cpu_resume
The armada_370_xp_cpu_resume() until now was used only as the function called by the SoC when returning from a deep idle state (as used in cpuidle, or when the CPU is brought offline using CPU hotplug).
However, it is now also used when exiting the suspend to RAM state. In this case, it is the bootloader that calls back into this function, with the MMU left enabled by the BootROM. Having the MMU enabled when entering this function confuses the kerrnel because we are not using the kernel page tables at this point, but in other mvebu functions we use the information on whether the MMU is enabled or not to find out whether we should talk to the coherency fabric using a physical address or a virtual address. To fix that, we simply disable the MMU when entering this function, so that the kernel is in an expected situation.

ARM: mvebu: add a common function for the boot address work around
On some of the mvebu SoCs and due to internal BootROM issue, the CPU initial jump code must be placed in the SRAM memory of the SoC. In order to achieve this, we have to unmap the BootROM and at some specific location where the BootROM was placed, create a dedicated MBus window for the SRAM. This SRAM is initialized with a few instructions of code that allows to jump to the real secondary CPU boot address. The SRAM used is the Crypto engine one.
This work around is currently needed for booting SMP on Armada 375 Z1 and will be needed for cpuidle support on Armada 370. Instead of duplicating the same code, this commit introduces a common function to handle it: mvebu_setup_boot_addr_wa().

ARM: mvebu: fix cpuidle implementation to work on big-endian systems
On Marvell Armada XP, when a CPU comes back from deep idle state of cpuidle, it restarts its execution at armada_370_xp_cpu_resum
ARM: mvebu: fix cpuidle implementation to work on big-endian systems
On Marvell Armada XP, when a CPU comes back from deep idle state of cpuidle, it restarts its execution at armada_370_xp_cpu_resume(), which puts back the CPU into the coherency, and then calls the generic cpu_resume() function.
While this works on little-endian configurations, it doesn't work on big-endian configurations because the CPU restarts in little-endian, and therefore must be switched back to big-endian to operate properly. To achieve this, a 'setend be' instruction must be executed in big-endian configurations. However, the ARM_BE8() macro that is used to implement nice compile-time conditional for ARM LE vs. ARM BE8 is not easily usable in inline assembly.
Therefore, this patch moves the armada_370_xp_cpu_resume() C function, which was anyway just a block of inline assembly, into a proper pmsu_ll.S file, and adds the appropriate ARM_BE8(setend be) instruction.
Without this patch, an Armada XP big endian configuration with cpuidle enabled fails to boot, as it hangs as soon as one of the CPU hits the deep idle state.

ARM: mvebu: make sure MMU is disabled in armada_370_xp_cpu_resume The armada_370_xp_cpu_resume() until now was used only as the function called by the SoC when returning from a deep idle state (as used in cpuidle, or when the CPU is brought offline using CPU hotplug). However, it is now also used when exiting the suspend to RAM state. In this case, it is the bootloader that calls back into this function, with the MMU left enabled by the BootROM. Having the MMU enabled when entering this function confuses the kerrnel because we are not using the kernel page tables at this point, but in other mvebu functions we use the information on whether the MMU is enabled or not to find out whether we should talk to the coherency fabric using a physical address or a virtual address. To fix that, we simply disable the MMU when entering this function, so that the kernel is in an expected situation.

ARM: mvebu: add a common function for the boot address work around On some of the mvebu SoCs and due to internal BootROM issue, the CPU initial jump code must be placed in the SRAM memory of the SoC. In order to achieve this, we have to unmap the BootROM and at some specific location where the BootROM was placed, create a dedicated MBus window for the SRAM. This SRAM is initialized with a few instructions of code that allows to jump to the real secondary CPU boot address. The SRAM used is the Crypto engine one. This work around is currently needed for booting SMP on Armada 375 Z1 and will be needed for cpuidle support on Armada 370. Instead of duplicating the same code, this commit introduces a common function to handle it: mvebu_setup_boot_addr_wa().

ARM: mvebu: fix cpuidle implementation to work on big-endian systems On Marvell Armada XP, when a CPU comes back from deep idle state of cpuidle, it restarts its execution at armada_370_xp_cpu_resume(), which puts back the CPU into the coherency, and then calls the generic cpu_resume() function. While this works on little-endian configurations, it doesn't work on big-endian configurations because the CPU restarts in little-endian, and therefore must be switched back to big-endian to operate properly. To achieve this, a 'setend be' instruction must be executed in big-endian configurations. However, the ARM_BE8() macro that is used to implement nice compile-time conditional for ARM LE vs. ARM BE8 is not easily usable in inline assembly. Therefore, this patch moves the armada_370_xp_cpu_resume() C function, which was anyway just a block of inline assembly, into a proper pmsu_ll.S file, and adds the appropriate ARM_BE8(setend be) instruction. Without this patch, an Armada XP big endian configuration with cpuidle enabled fails to boot, as it hangs as soon as one of the CPU hits the deep idle state.
