sh: Merge _32/_64 ioremap implementations.

2010-01-18T12:21:32+00:00

There is nothing of interest in the _64 version anymore, so the _32 one can be renamed and used unconditionally. Signed-off-by: Paul Mundt

sh: Handle early ioremaps through fixed mappings.

2010-01-18T12:08:32+00:00

This adds in a mem_init_done to work out when a standard ioremap() is possible, falling back to the fixmap based ioremap otherwise. Signed-off-by: Paul Mundt

sh: Tidy up non-translatable checks in iounmap path.

2010-01-16T16:45:26+00:00

This tidies up the iounmap path with consolidated checks for nontranslatable mappings. This is in preparation of unifying the implementations. Signed-off-by: Paul Mundt

sh: wire up vmallocinfo support in ioremap() implementations.

2009-12-14T05:23:41+00:00

This wires up the caller information for the ioremap VMA, which allows for more helpful caller tracking via /proc/vmallocinfo. Follows the x86 and powerpc changes of the same nature. Signed-off-by: Paul Mundt

sh: Try PMB mapping based on physical address, not mapping size

2009-10-09T02:25:10+00:00

We should favour PMB mappings when the physical address cannot be reached with 29-bits. Signed-off-by: Matt Fleming Signed-off-by: Paul Mundt

sh: Fix overzealous checking in __ioremap()

2009-08-24T09:29:25+00:00

Allow peripherals before the start of RAM to be remapped. Signed-off-by: Stuart Menefy Signed-off-by: Paul Mundt

sh: pci: Rework fixed region checks in ioremap().

2009-04-20T09:24:57+00:00

Not all PCI channels have non-translatable memory windows, this is a special property of the on-chip PCIC with its 0xfd00... mapping, handle this explicitly. Signed-off-by: Paul Mundt

sh: pci memory range checking code

2009-04-16T07:00:14+00:00

This patch changes the code to use __is_pci_memory() instead of is_pci_memaddr(). __is_pci_memory() loops through all the pci channels on the system to match memory windows. Signed-off-by: Magnus Damm Signed-off-by: Paul Mundt

sh: Support fixed 32-bit PMB mappings from bootloader.

2009-03-10T06:49:54+00:00

This provides a method for supporting fixed PMB mappings inherited from the bootloader, as an alternative to the dynamic PMB mapping currently used by the kernel. In the future these methods will be combined. P1/P2 area is handled like a regular 29-bit physical address, and local bus device are assigned P3 area addresses.

sh: fix P4 iounmap() pass-through

2009-02-27T07:50:00+00:00

Fix iounmap() of pass-through P4 addresses. Without this patch iounmap() on the sh7780 rtc area results in a warning message. Signed-off-by: Magnus Damm Signed-off-by: Paul Mundt
