* rework remap_rangeSascha Hauer2015-11-031-18/+6
| | | | | | | | | | | | | | | | | | remap_range is for remapping regions with different cache attributes. It is implemented for ARM and PowerPC only, the other architectures only provide stubs. Currently the new cache attributes are passed in an architecture specific way and the attributes have to be retrieved by calls to mmu_get_pte_cached_flags() and mmu_get_pte_uncached_flags(). Make this simpler by providing architecture independent flags which can be directly passed to remap_range() Also provide a MAP_ARCH_DEFAULT flag and a arch_can_remap() function. The MAP_ARCH_DEFAULT defaults to whatever caching type the architecture has as default. the arch_can_remap() function returns true if the architecture can change the cache attributes, false otherwise. This allows the memtest code to better find out what it has to do. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* dma: Use generic place for dma_addr_t typedefSascha Hauer2015-05-221-3/+0
| | | | | | | | | Instead of letting all architectures define their own dma_addr_t use a common place in include/linux/types.h and use a Kconfig symbol that architectures can select to define the width of dma_addr_t. The same is done in the Kernel. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | Add DDR3 support into the MPC8xxx DDR driver. To avoid confusion, the function set_ddr_sdram_mode is renamed set_ddr2_sdram_mode. Checking for errors is simplified in the DDR2 DIMM parameters computation to be consistent with DDR3.

| | | | | | | | | | | | | | | | | | | | | | | | | | TLB support for the 85xx CPUs has been upgraded to support the MMUv2 page size definitions. This has been imported from U-Boot version git-9407c3fc. This allows for future CPUs to make use of the new MMU support.

|/ | | | | | | | | | | | | Removed the ppc bit operation functions and definitions in the ppc file asm/bitops.h since these are already defined in the asm-generic header files. Moved ffs64 definition to the mpc85xx header files because the function requires the inclusion of linux/log2.h which also includes asm/bitops.h.

* ppc: bootm: relocate fdt to valid boot memoryRenaud Barbier2013-09-091-0/+3
| | | | | | | | | | | | | | For the MPC85xx family of SOCs Linux expects any boot firmware information to be passed in the first 64MiB of memory. This adds support to ensure that the device tree is relocated to a valid location if it is outside that address range. For the other SOC family currently present in the ppc architecture, the default is not to relocate as at Linux startup the virtual address equals the physical address.

All MPC5200 configuration is moved to the MPC5200 architecture specific configuration file. These modifications are reflected in the PCM030 board support. arch/ppc/Makefile compilation directives are updated in preparation for the introduction of future cpus/machines. lib/time.c is moved to the architecture specific directory and the building instructions updated in the Make files. The file is cleaned up of unused code. The definition of L1_CACHE_... is updated and CACHELINE_SIZE is defined in ppc/include/asm/cache.h for future use by the mpc85xx. The file mach-mpc5xxx/pci_mpc5200.c and mach-mpc5xxx/start.S are updated accordingly. The declaration of search_exception_table is moved in include/asm/common.h because it is used across architectures. mach-mpc5xxx/traps.c is also updated to reflect this change. The definition of exception in asm/ppc_asm.tmpl is updated for future use by the mpc85xx. The file starts.S in mach-mpc5xxx is updated accordingly.
