* [MIPS] Make ioremap() work on TX39/49 special unmapped segmentAtsushi Nemoto2007-07-10
| | | | | | | | | | | | | 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.

* [MIPS] Fix PHYS_OFFSET for 64-bits kernels with 32-bits symbolsFranck Bui-Huu2007-07-10
| | | | | | | | | | | | | | | | | | | 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.

* [MIPS] Make PAGE_OFFSET aware of PHYS_OFFSETFranck Bui-Huu2007-07-10
| | | | | | | | | | | 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.

* [MIPS] Clean up asm-mips/mach-generic/spaces.hFranck Bui-Huu2007-07-10
| | | | | | | | | | | | | 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>
* [MIPS] Allow generic spaces.h to be included by platform specific onesFranck Bui-Huu2007-07-10
| | | | | | | | | | | | | | | | | | | | | 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.

* [MIPS] Cleanup TO_PHYS_MASK definitionRalf Baechle2007-07-10
| | | | | | | | | No point in adding yet another #ifdef for Loongson since all this mask is being used for is converting an XKPHYS address into a physical address anyway.

* [MIPS] Fix scheduling latency issue on 24K, 34K and 74K coresRalf Baechle2007-07-06
| | | | | | | | | | | | | | | | | | | | | | | The idle loop goes to sleep using the WAIT instruction if !need_resched(). This has is suffering from from a race condition that if if just after need_resched has returned 0 an interrupt might set TIF_NEED_RESCHED but we've just completed the test so go to sleep anyway. This would be trivial to fix by just disabling interrupts during that sequence as in: local_irq_disable(); if (!need_resched()) __asm__("wait"); local_irq_enable(); but the processor architecture leaves it undefined if a processor calling WAIT with interrupts disabled will ever restart its pipeline and indeed some processors have made use of the freedom provided by the architecture definition. This has been resolved and the Config7.WII bit indicates that the use of WAIT is safe on 24K, 24KE and 34K cores. It also is safe on 74K starting revision 2.1.0 so enable the use of WAIT with interrupts disabled for 74K based on a c0_prid of at least that. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* [MIPS] Add macros to encode processor revisions.Ralf Baechle2007-07-06
| | | | | | | | | Older processors used to encode processor version and revision in two 4-bit bitfields, the 4K seems to simply count up and even newer MTI cores have switched to use the 8-bits as 3:3:2 bitfield with the last field as the patch number.
