* avr32: Remove second definition of virt_to_phys()Haavard Skinnemoen2008-12-17-7/+2
| | | | | | | | | | The second definition introduced by 65e43a1063 conflicts with the existing one. Also, convert the existing definition to use phys_addr_t. The volatile qualifier is still needed due to brain damage elsewhere. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
* Introduce virt_to_phys()Kumar Gala2008-12-15-0/+5
| | | | | | | | | | | | virt_to_phys() returns the physical address given a virtual. In most cases this will be just the input value as the vast majority of systems run in a 1:1 mode. However in systems that are not running this way it should report the physical address or ~0 if no mapping exists for the given virtual address. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* Introduce phys_size_t and move phys_addr_t into asm/types.hKumar Gala2008-04-13-2/+0
| | | | | | | Also add CONFIG_PHYS_64BIT on powerpc to deal with 32-bit ppc's that have larger physical addresses like 44x, 85xx, and 86xx. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* Introduce map_physmem() and unmap_physmem()Haavard Skinnemoen2007-12-13-0/+32
| | | | | | | | | | | | | | | | map_physmem() returns a virtual address which can be used to access a given physical address without involving the cache. unmap_physmem() should be called when the virtual address returned by map_physmem() is no longer needed. This patch adds a stub implementation which simply returns the physical address cast to a uchar * for all architectures except AVR32, which converts the physical address to an uncached virtual mapping. unmap_physmem() is a no-op on all architectures, but if any architecture needs to do such mappings through the TLB, this is the hook where those TLB entries can be invalidated.

* [PATCH v3] Add sync to ensure flash_write_cmd is fully finishedHaiying Wang2007-02-21-0/+4
| | | | | | | | | Some CPUs like PPC, BLACKFIN need sync() to ensure cfi flash write command is fully finished. The sync() is defined in each CPU's io.h file. For those CPUs which do not need sync for now, a dummy sync() is defined in their io.h as well. Signed-off-by: Haiying Wang <Haiying.Wang@freescale.com>
