* rework remap_rangeSascha Hauer2015-11-031-13/+1
| | | | | | | | | | | | | | | | | | 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>
* x86: use generic posix_types.hSascha Hauer2015-06-031-44/+1
| | | | | | | Use generic asm-generic/posix_types.h instead of repeating the typedefs. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* introduce bitsperlong.h for remaining architecturesSascha Hauer2015-06-032-1/+2
| | | | | | | | This introduces the bitsperlong.h file for the remaining architectures. It's purpose is to define BITS_PER_LONG which in the next step can be used by a generic posix_types.h file. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* consistently use the same bitops.h fileSascha Hauer2014-07-171-13/+17
| | | | | | | | | | | | | | | | We have many variants of the same bitops.h file. Consistently use the same file for all architectures which completely use the generic bitops versions. Some architectures had static inline versions of functions identically to the generic versions, these are removed and the generic versions are used directly now. Also several architectures depend on the generic find_*_bit functions but didn't have the GENERIC_FIND_NEXT_BIT Kconfig option selected. This is added where needed.

* x86: ns16550: Rework driver to allow for x86 I/O spaceMichel Stam2014-04-091-3/+0
| | | | | | | | | | | | The current implementation fakes a memory-mapped I/O device at 0x3f8 and 0x2f8, then uses platform read/write functions to do the actual reading and writing. These platform functions only exist for the x86 platform; better to move the I/O routines into the driver and have the driver request I/O ports using request_ioport_region.

* remap_range: make function 'remap_range' globalAlexander Aring2013-01-181-0/+18
| | | | | | | | | | | | Change function remap_range in arm architecture to make it global accessable. For example command 'memtest' can change pte flags to enable or disable cache. Add dummy function for others architectures that doesn't have mmu or pte support. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * blackfin, mips, openrisc, ppc, sandbox, x86: add generic dma_alloc, dma_free ↵Marc Kleine-Budde2012-06-301-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | inlines Some drivers call dma_inv_range() on buffers, on arm these buffers must be cache line aligned. This patch introduces a generic dma_alloc, dma_free. Archs can implement in their own functions in "asm/dma.h" and add a: #define dma_alloc dma_alloc #define dma_free dma_free On all other archs the generic versions, which translate into xmalloc and free are used.
