microblaze: Fix sparse warning - timer.c

2011-03-09T07:09:57+00:00

Variables and init_microblaze_timecounter should be static.

Warning log:
CHECK   arch/microblaze/kernel/timer.c
arch/microblaze/kernel/timer.c:41:14: warning: symbol 'freq_div_hz' was not declared. Should it be static?
arch/microblaze/kernel/timer.c:42:14: warning: symbol 'timer_clock_freq' was not declared. Should it be static?
arch/microblaze/kernel/timer.c:205:12: warning: symbol 'init_microblaze_timecounter' was not declared. Should it be static?

microblaze: convert to clocksource_register_hz/khz

2011-02-21T21:33:46+00:00

This converts the microblaze clocksources to use clocksource_register_hz/khz

microblaze: Support timer on AXI lite

2010-10-21T05:52:00+00:00

New microblaze systems uses two buses. One for memories
and flashes and the second for low-speed peripherals
which can run on different CLK. This is the reason
why the kernel is trying to read clock-frequency
directly from node. If there is then the kernel will
work with it. If not then cpu CLK is used.

microblaze: Add support for little-endian Microblaze

2010-10-21T05:51:59+00:00

Microblaze little-endian toolchain exports __MICROBLAZEEL__
which is used in the kernel to identify little/big endian.

The most of the changes are in loading values from DTB which
is always big endian.

Little endian platforms are based on new AXI bus which has
impact to early uartlite initialization.

microblaze: Remove additional compatible properties

2010-10-21T05:51:47+00:00

Device-tree BSP generates longer compatible properties
that's why we can remove extra/old one.

microblaze: Report if only one timer is used

2010-10-21T05:51:30+00:00

Kernel needs two timers because of clocksource and clockevent.
It is better to show warning message directly on early
console if available. If it isn't available kernel log buffer
contains it.

microblaze: Decrease time shifting values

2010-08-04T08:22:39+00:00

Lower shifting values ensure that shifted 32bit counter
value doesn't exceed 64bit cycle variable too fast.

microblaze: Improve ftrace time measuring

2010-08-04T08:22:35+00:00

I had to comment sched_clock generic function because of broken toolchain.
It is fine grain timing.
