[MIPS] Updated Sibyte headers

2007-04-27T15:20:24+00:00

This is an update to the earlier patch for the sibyte headers, and superceeds
the previous patch.  Changes were necessary to get the tbprof driver working
on the bcm1480.

Patch to update Sibyte header files to match master versions maintained
at Broadcom.  This patch also corrects some whitespace problems, and
(hopefully) shouldn't introduce any new ones.

[MIPS] Add missing silicon revisions for BCM112x

2007-04-20T13:58:37+00:00

Recent versions of the BCM112X processors aren't recognized by Linux
(preventing Linux from booting on those processors).  This patch adds
support for those that are missing.

[MIPS] Fixup migration to GENERIC_TIME

2006-10-31T20:13:23+00:00

Since we already moved to GENERIC_TIME, we should implement alternatives
of old do_gettimeoffset routines to get sub-jiffies resolution from
gettimeofday().  This patch includes:

 * MIPS clocksource support (based on works by Manish Lachwani).
 * remove unused gettimeoffset routines and related codes.
 * remove unised 64bit do_div64_32().
 * simplify mips_hpt_init. (no argument needed, __init tag)
 * simplify c0_hpt_timer_init. (no need to write to c0_count)
 * remove some hpt_init routines.
 * mips_hpt_mask variable to specify bitmask of hpt value.
 * convert jmr3927_do_gettimeoffset to jmr3927_hpt_read.
 * convert ip27_do_gettimeoffset to ip27_hpt_read.
 * convert bcm1480_do_gettimeoffset to bcm1480_hpt_read.
 * simplify sb1250 hpt functions. (no need to subtract and shift)

[MIPS] Sibyte: Fix race in sb1250_gettimeoffset().

2006-03-18T16:59:30+00:00

    
From Dave Johnson :
    
sb1250_gettimeoffset() simply reads the current cpu 0 timer remaining
value, however once this counter reaches 0 and the interrupt is raised,
it immediately resets and begins to count down again.
    
If sb1250_gettimeoffset() is called on cpu 1 via do_gettimeofday() after
the timer has reset but prior to cpu 0 processing the interrupt and
taking write_seqlock() in timer_interrupt() it will return a full value
(or close to it) causing time to jump backwards 1ms. Once cpu 0 handles
the interrupt and timer_interrupt() gets far enough along it will jump
forward 1ms.
    
Fix this problem by implementing mips_hpt_*() on sb1250 using a spare
timer unrelated to the existing periodic interrupt timers. It runs at
1Mhz with a full 23bit counter.  This eliminated the custom
do_gettimeoffset() for sb1250 and allowed use of the generic
fixed_rate_gettimeoffset() using mips_hpt_*() and timerhi/timerlo.

[MIPS] Sibyte: Fix M_SCD_TIMER_INIT and M_SCD_TIMER_CNT wrong field width.

2006-03-18T16:59:29+00:00

    
From Dave Johnson :
    
Field width should be 23 bits not 20 bits.
