MIPS: APRP: Choose the correct VPE loader by fixing the linking

2014-03-06T20:20:23+00:00

Now we have CONFIG_MIPS_VPE_LOADER and CONFIG_MIPS_VPE_LOADER_[CMP|MT]. The
latter two are used by the 2 exclusive flavors. The vpe_run in malta-amon.c
is for CMP APRP. Without the fix, this vpe_run will be used in MT APRP.

MIPS: APRP: Fix the linking of rtlx interrupt hook

2014-03-06T19:52:29+00:00

There are 2 errors with the existing aprp_hook linking:
- The prefix CONFIG_ is missing;
- The hook should be linked exclusively in the cases of MT and CMP.

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: Malta: use generic 8250 early console

2014-01-23T12:02:35+00:00

This patch switches Malta from using the MIPS implementation of early
printk with Malta's prom_putchar to using the generic 8250_early
implementation. This offers a couple of advantages:

  - We duplicate less generic code.

  - The UART can be initialised rather than being reliant upon
    inheriting a valid setup from the bootloader.

The Malta console_config function is extended to initialise the early
console if no earlycon= kernel parameter is provided, inheriting the
modetty0 bootloader environment if present and falling back to a
default 38400n8r setup if not. This matches the behaviour used for the
regular console= parameter.

MIPS: Malta: initialise the RTC at boot

2014-01-23T12:02:35+00:00

The RTC is used on Malta to estimate the clock frequency of the CPU &
optionally the GIC. However the kernel previously did not initialise the
RTC, instead relying upon the bootloader having done so. In order to
minimise dependencies which the kernel has upon the bootloader this
patch causes the kernel to initialise the RTC itself prior to making use
of it.

MIPS: Malta: remove unused cpu_khz variable

2014-01-23T12:02:35+00:00

This variable was introduced by commit 96348c8f (of Ralf's historic
Linux/MIPS repository) "Remaining fixes for MIPS's eval boards." but
I don't see any use of it either then or now. Remove it.

MIPS: Malta: Remove ttyS2 serial for CMP platforms

2014-01-22T19:18:57+00:00

Commit 225ae5fd9a320e22841410049c3bdb6cf14a5841
"MIPS: Malta: Fix interupt number of CBUS UART"

fixed the IRQ number for the ttyS2 CBUS UART. However, this now
conflicts with the GIC IPI1 interrupt in CMP platforms. The Malta
interrupt code arbitrarily binds IPIs to INT2 and INT3 and since
ttyS2 uses the INT2 IRQ line, closing the device disables the
INT2 interrupt and this effectively disables the IPI1 interrupt
as well. This patch is mainly a workaround until the Malta code
is fixed properly.

Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus

2013-11-07T23:32:58+00:00

Pull MIPS updates from Ralf Baechle:
 - Some minor work bringing the Cobalt MIPS platforms in line with other
   MIPS platforms
 - Make vmlinux.32 and vmlinux.64 build messages less verbose
 - Always register the R4k clocksource when selected, the clock source's
   rating will decide if this or another clock source is actually going
   to be used
 - Drop support for the Cisco (formerly Scientific Atlanta) PowerTV
   platform.  There appears to be nobody left who cares and the USB
   driver went stale while waiting for years to be merged
 - Some cleanup of Loongson 2 related #ifdefery
 - Various minor cleanups
 - Major rework on all things related to tracing / ptrace on MIPS,
   including switching the MIPS ELF core dumper to regsets, enabling the
   entries for SIGSYS in struct siginfo for MIPS, enabling ftrace
   syscall trace points
 - Some more work to bring DECstation support code in line with other
   more modern code
 - Report the name of the detected CPU, not just its CP0 PrID value
 - Some more BCM 47xx and atheros ath79xx work
 - Support for compressed kernels using the XZ compression scheme
