2016-08-26ARM: Move SYS_CACHELINE_SIZE over to KconfigTom Rini
This series moves the CONFIG_SYS_CACHELINE_SIZE. First, in nearly all cases we are mirroring the values used by the Linux Kernel here. Also, so long as (and in this case, it is true) we implement flushes in hunks that are no larger than the smallest implementation (and given that we mirror the Linux Kernel, again we are fine) it is OK to align higher. The biggest changes here are that we always use 64 bytes for CPU_V7 even if for example the underlying core is only 32 bytes (this mirrors Linux). Second, we say ARM64 uses 64 bytes not 128 (as found in the Linux Kernel) as we do not need multi-platform support (to this degree) and only the Cavium ThunderX 88xx series has a use for such large alignment.

2016-08-06armv8: mmu: Detect page table overflow in emergency pt creationAlexander Graf
We create 2 sets of page tables: One for normal operation, one for emergency (used while modifying the former). Because the page tables grow dynamically, we have code that checks for overflow. Unfortunately we didn't adjust the available space variable while creating the emergency tables, so potentially someone might run into an overflow there (not seen in real world yet though!). Fix it by properly adjusting the size as well as the base offset in emergency page table creation.

2016-08-05treewide: move CONFIG_PHYS_64BIT to KconfigMasahiro Yamada
We need to ensure that CONFIG_PHYS_64BIT is configured via Kconfig so that it is always available to the build system. Otherwise we can run into cases where we have inconsistent sizes of certain attributes. Ravi Babu reported offset mismatch of struct dwc3 across files since commit 95ebc253e6d4 ("types.h: move and redefine resource_size_t"). Since the commit, resource_addr_t points to phys_addr_t, whose size is dependent on CONFIG_PHYS_64BIT for ARM architecture. I tried my best to use "select" where possible (for example, ARMv8 architecture) because I think this kind of option is generally user- unconfigurable. However, I see some of PowerPC boards have 36BIT defconfigs as well as 32BIT ones. I moved CONFIG_PHYS_64BIT to the defconfigs for such boards. CONFIG_36BIT is no longer referenced, so all of the defines were removed from CONFIG_SYS_EXTRA_OPTIONS.

2016-08-05ARM: Rework and correct barrier definitionsTom Rini
As part of testing booting Linux kernels on Rockchip devices, it was discovered by Ziyuan Xu and Sandy Patterson that we had multiple and for some cases incomplete isb definitions. This was causing a failure to boot of the Linux kernel. In order to solve this problem as well as cover any corner cases that we may also have had a number of changes are made in order to consolidate things. First, <asm/barriers.h> now becomes the source of isb/dsb/dmb definitions. This however introduces another complexity. Due to needing to build SPL for 32bit tegra with -march=armv4 we need to borrow the __LINUX_ARM_ARCH__ logic from the Linux Kernel in a more complete form. Move this from arch/arm/lib/Makefile to arch/arm/Makefile and add a comment about it. Now that we can always know what the target CPU is capable off we can get always do the correct thing for the barrier. The final part of this is that need to be consistent everywhere and call isb()/dsb()/dmb() and NOT call ISB/DSB/DMB in some cases and the function names in others.

A couple of commits have modified the am33xx/am437x ddr2/ddr3 initialization path to fix certain issues, but have had the side effect of causing L3 noc errors during initialization.

This delays initialization and refresh until a later stage. The 500us timer can be programmed for platforms that require it and for platforms that don't require it. It is currently hardcoded for 400MHz systems. For systems with a higher memory frequency this needs to be a larger value, and for systems with a lower memory frequency this can be a lower value.
