2007-07-10[MIPS] Make ioremap() work on TX39/49 special unmapped segmentAtsushi Nemoto5-0/+110
TX39XX and TX49XX have "reserved" segment in CKSEG3 area. 0xff000000-0xff3fffff on TX49XX and 0xff000000-0xfffeffff on TX39XX are reserved (unmapped, uncached). Controllers on these SoCs are placed in this segment. This patch add plat_ioremap() and plat_iounmap() to override default behavior and implement these hooks for TX39/TX49.

2007-07-10[MIPS] Fix PHYS_OFFSET for 64-bits kernels with 32-bits symbolsFranck Bui-Huu1-4/+8
The current implementation of __pa() for 64-bits kernels with 32-bits symbols is broken. In this configuration, we need 2 values for PAGE_OFFSET, one in XKPHYS and the other in CKSEG0 space. When the value in CKSEG0 space is used, it doesn't take into account of PHYS_OFFSET. Even worse we can't redefine this value. The patch restores CPHYSADDR() but in __pa()'s implementation because it removes the need of 2 PAGE_OFFSET. OTOH, CPHYSADDR() is quite bad when dealing with mapped kernels. So this patch assumes there's no need to deal with such kernel in 64-bits world. Signed-off-by: Franck Bui-Huu <fbuihuu@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-07-10[MIPS] Make PAGE_OFFSET aware of PHYS_OFFSETFranck Bui-Huu1-1/+1
For platforms that use PHYS_OFFSET and do not use a mapped kernel, this patch automatically adds PHYS_OFFSET into PAGE_OFFSET. Therefore there are no more needs for them to redefine PAGE_OFFSET. For mapped kernel, they need to redefine PAGE_OFFSET anyways. Signed-off-by: Franck Bui-Huu <fbuihuu@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-07-10[MIPS] Clean up asm-mips/mach-generic/spaces.hFranck Bui-Huu1-38/+27
PAGE_OFFSET definition is now using CAC_BASE by default. This patch also reorder some macros to make them appear in the same order for both 32 and 64 bits configs. It also makes use of const.h generic header file to annotate constants. Signed-off-by: Franck Bui-Huu <fbuihuu@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-07-10[MIPS] Allow generic spaces.h to be included by platform specific onesFranck Bui-Huu4-73/+23
Before this patch, when a platform needed to customize one constant in spaces.h, they need to redefine all of them. Now they can just redefine one constant and include the generic file header at the end: #include <asm/mach-generic/spaces.h> This patch doesn't allow to redefine CAC_BASE, IO_BASE and UNCAC_BASE for 32 bits platforms because there's no need to do so. This will avoid some macro duplications. It's important specially if we'll add complex macros.

2007-07-09ide: add short cables supportBartlomiej Zolnierkiewicz1-1/+2
This patch allows users to override both host and device side cable detection with "ideX=ata66" kernel parameter. Thanks to this it should be now possible to use UDMA > 2 modes on systems (laptops mainly) which use short 40-pin cable instead of 80-pin one. Next patches add automatic detection of some systems using short cables. Changes: * Rename hwif->udma_four to hwif->cbl and make it u8. * Convert all existing users accordingly (use ATA_CBL_* defines while at it). * Add ATA_CBL_PATA40_SHORT support to ide-iops.c:eighty_ninty_three(). * Use ATA_CBL_PATA40_SHORT for "ideX=ata66" kernel parameter.
