xtensa: io: remove dummy relaxed accessor macros for reads

2014-10-20T17:49:17Z

These are now defined by asm-generic/io.h, so we don't need the private definitions anymore. Cc: Chris Zankel Acked-by: Max Filippov Signed-off-by: Will Deacon

xtensa: fix warning '"CONFIG_OF" is not defined'

2014-01-19T15:29:13Z

The warning only shows up when building MMUv3 configuration with OF support disabled. Signed-off-by: Max Filippov

xtensa: remap io area defined in device tree

2014-01-14T20:25:14Z

Use the simple-bus node to discover the io area, and remap the cached and bypass io ranges. The parent-bus-address value of the first triplet in the "ranges" property is used. This value is rounded down to the nearest 256MB boundary. The length of the io area is fixed at 256MB; the "ranges" property length value is ignored. Other limitations: (1) only the first simple-bus node is considered, and (2) only the first triplet of the "ranges" property is considered. See ePAPR 1.1 §6.5 for the simple-bus node description, and §2.3.8 for the "ranges" property description. Signed-off-by: Baruch Siach Signed-off-by: Max Filippov

xtensa: avoid duplicate of IO range definitions

2014-01-14T20:21:24Z

Define IO addresses in a single place, to make it easier to change for non-standard memory maps. Signed-off-by: Baruch Siach Signed-off-by: Max Filippov

xtensa: use physical addresses for bus addresses

2012-10-25T21:53:36Z

Define virt_to_bus and bus_to_virt as virt_to_phys, and phys_to_virt, respectively. Signed-off-by: Chris Zankel

xtensa: fix ioremap

2012-10-03T22:11:35Z

- fix ioremap_nocache to actually return non-cacheable address - add explicit ioremap_cache - fix KIO aperture checking arithmetic Signed-off-by: Max Filippov Signed-off-by: Chris Zankel

xtensa: fix build error in xtensa/include/asm/io.h

2012-04-23T16:30:03Z

Caused by commit 6c03438edeb5c359af35f060ea016ca65671c269 kernel.h: doesn't explicitly use bug.h, so don't include it. This header uses bug.h so explicitly include it now that the implicit presence was removed by 6c03438ed. Signed-off-by: Paul Gortmaker

xtensa: nommu support

2009-04-03T06:41:50Z

Add support for !CONFIG_MMU setups. Signed-off-by: Johannes Weiner Signed-off-by: Chris Zankel

xtensa: move headers files to arch/xtensa/include

2008-11-06T18:25:09Z

Move all header files for xtensa to arch/xtensa/include and platform and variant header files to the appropriate arch/xtensa/platforms/ and arch/xtensa/variants/ directories. Moving the files gets also rid of all uses of symlinks in the Makefile. This has been completed already for the majority of the architectures and xtensa is one out of six missing.
