* [MIPS] EV64120: Remove supportYoichi Yuasa2007-07-1059-1708/+2

* [MIPS] DECstation: Optimised early printk()Maciej W. Rozycki2007-07-103-7/+29
| | | | | | | | | | | | | | | | | | | | | | | This is an optimised implementation of early printk() for the DECstation. After the recent conversion to a MIPS-specific generic routine using a character-by-character output the performance dropped significantly. This change reverts to the previous speed -- even at 9600 bps of the serial console the difference is visible with a naked eye; I presume for a framebuffer it is even worse (it may depend on exactly which one is used though). Additionally the change includes a fix for a problem that the old implementation had -- the format used would not actually limit the length of the string output. This new implementation uses a local buffer to deal with it -- even with this additional copying it is much faster than the generic function. Plus this driver is registered much earlier than the generic one, allowing one to see critical messages, such as one about an incorrect CPU setting used, that are produced beforehand. :-) Signed-off-by: Maciej W.

* [MIPS] Fix PHYS_OFFSET for 64-bits kernels with 32-bits symbolsFranck Bui-Huu2007-07-101-4/+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.

* [MIPS] Make PAGE_OFFSET aware of PHYS_OFFSETFranck Bui-Huu2007-07-101-1/+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.

* [MIPS] Clean up asm-mips/mach-generic/spaces.hFranck Bui-Huu2007-07-101-38/+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.

* [MIPS] Allow generic spaces.h to be included by platform specific onesFranck Bui-Huu2007-07-104-73/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on patch "the scheduled removal of RAW1394_REQ_ISO_{SEND,LISTEN}" from Adrian Bunk, November 20 2006. This patch also removes the underlying facilities in ohci1394 and disables them in pcilynx. That is, hpsb_host_driver.devctl() and hpsb_host_driver.transmit_packet() are no longer used for iso reception and transmission. Since video1394 and dv1394 only work with ohci1394 and raw1394's rawiso interface has never been implemented in pcilynx, pcilynx is now no longer useful for isochronous applications. raw1394 will still handle the request types but will complete the requests with errors that indicate API version conflicts.
