2016-01-20ARM: uniphier: fix range invalidate for outer cacheMasahiro Yamada
If invalidate operation is invoked against a cache-unaliged region, the both ends of the region should be flushed, not invalidated. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-01-20ARM: uniphier: factor out outer cache sync as a helper functionMasahiro Yamada

2016-01-20ARM: uniphier: add bootm_low environmentMasahiro Yamada
The load address of the kernel can be changed via "kernel_addr_r" environment. The device tree and the initramdisk should be relocated according to the kernel location. The "bootm_low" should be calculated by masking the lower bits (TEXT_OFFSET part) of the "kernel_addr_r" environment value. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-01-20ARM: uniphier: define CONFIG_SYS_BOOTMAPSZMasahiro Yamada
U-Boot relocates the device tree and the initramdisk to the tail of the memory region before booting the kernel. Some UniPhier boards are equipped with a large amount of memory. For those boards, the device tree and the initramdisk are placed out of the the kernel causing a kernel panic. Add CONFIG_SYS_BOOTMAPSZ to prevent them from going too high.

2016-01-19armv8: New MMU setup code allowing to use 48+ bits PA/VASergey Temerkhanov
This patch adds code which sets up 2-level page tables on ARM64 thus extending available VA space. CPUs implementing 64k translation granule are able to use direct PA-VA mapping of the whole 48 bit address space.

2016-01-16MIPS: sync I/O related header files with linux-4.4Daniel Schwierzeck
Mainly sync asm/io.h to get a working ioremap() implementation as well as the full set of I/O accessors. Pull in additional header files to make this work. Furthermore port over the directory 'arch/mips/include/asm/mach-generic/' with contains default definitions for I/O and memory spaces and default implementations for mapping those spaces.

2016-01-16net: pcnet: refactor mapping of virtual addresses to physical onesDaniel Schwierzeck
pci_virt_to_mem() uses virt_to_phys() to get the physical address. But pci_virt_to_mem() is also called with uncached addresses which is wrong according to the documentation of virt_to_phys(). Refactor the PCI_TO_MEM() macro to optionally map an uncached address back to a cached one before calling pci_virt_to_mem(). Currently pcnet works because virt_to_phys() is incorrectly implemented on MIPS. With the upcoming asm header file update for MIPS, the virt_to_phys() implementation will be fixed. Thus this patch is needed to keep pcnet working on MIPS Malta board. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
2016-01-16MIPS: kconfig: add option for MIPS_L1_CACHE_SHIFTDaniel Schwierzeck
Add Kconfig symbol for L1 cache shift like the kernel does. The value of CONFIG_SYS_CACHELINE_SIZE is not a reliable source for ARCH_DMA_MINALIGN anymore, because it is optional on MIPS. If CONFIG_SYS_CACHELINE_SIZE is not defined by a board, the cache sizes are automatically detected and ARCH_DMA_MINALIGN would be set to 128 Bytes. The default value for CONFIG_MIPS_L1_CACHE_SHIFT is 5 which corresponds to 32 Bytes. All current MIPS boards already used that value. While on it, fix the Malta board to use a value of 6 like the kernel port does. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
