MIPS: Use current_cpu_type() instead of c->cputype

2014-03-31T16:17:12+00:00

If current_cpu_type() is pre-defined in cpu-feature-overrides.h, This
may save about 10k for the compressed kernel image(vmlinuz).

mips: delete non-required instances of include

2014-01-24T21:39:56+00:00

None of these files are actually using any __init type directives
and hence don't need to include .  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

MIPS: bcm63xx: cpu: Replace BUG() with panic()

2014-01-24T21:39:52+00:00

BUG() can be a noop if CONFIG_BUG is not selected,
leading to the following build problem on a randconfig:

arch/mips/bcm63xx/cpu.c: In function 'detect_cpu_clock':
arch/mips/bcm63xx/cpu.c:254:1: error: control reaches end of
non-void function [-Werror=return-type]

We fix this problem by replacing BUG() with panic() since it's
best to handle the case of an unknown board instead of silently
returning a random clock frequency.

MIPS: BCM63XX: use linux/serial_bcm63xx.h

2014-01-23T12:02:36+00:00

Update the early_printk code to include linux/serial_bcm63xx.h which
provides the definitions for the UART block registers. While at it,
remove the inclusion of serial_bcm63xx.h which was just there to allow
smooth transition.

MIPS: BCM63XX: let the individual SoCs select the appropriate CPUs

2014-01-22T19:18:53+00:00

Let each supported chip select the appropirate SYS_HAS_CPU_BMIPS*
option for its embedded processor, so support will be conditionally
included.

MIPS: BMIPS: add a smp ops registration helper

2014-01-22T19:18:52+00:00

Add a helper similar to the generic register_XXX_smp_ops() for bmips.
Register SMP UP ops in case of BMIPS32/3300.

MIPS: BMIPS: change compile time checks to runtime checks

2014-01-22T19:18:51+00:00

Allow building for all bmips cpus at the same time by changing ifdefs
to checks for the cpu type, or adding appropriate checks to the
assembly.

Since BMIPS43XX and BMIPS5000 require different IPI implementations,
split the SMP ops into one for each, so the runtime overhead is only
at registration time for them.
