powerpc/5xxx: Add common mpc5xxx_get_bus_frequency() function

2009-06-17T06:30:22+00:00

So far, MPC512x used mpc512x_find_ips_freq() to get the bus frequency,
while MPC52xx used mpc52xx_find_ipb_freq().  Despite the different
clock names (IPS vs. IPB) the code was identical.

Use common code for both processor families.

powerpc: Add configurable -Werror for arch/powerpc

2009-06-16T04:15:45+00:00

Add the option to build the code under arch/powerpc with -Werror.

The intention is to make it harder for people to inadvertantly introduce
warnings in the arch/powerpc code. It needs to be configurable so that
if a warning is introduced, people can easily work around it while it's
being fixed.

The option is a negative, ie. don't enable -Werror, so that it will be
turned on for allyes and allmodconfig builds.

The default is n, in the hope that developers will build with -Werror,
that will probably lead to some build breaks, I am prepared to be flamed.

It's not enabled for math-emu, which is a steaming pile of warnings.

powerpc: Implement GPIO driver for simple memory-mapped banks

2008-12-30T17:13:45+00:00

The driver supports very simple GPIO controllers, that is, when a
controller provides just a 'data' register. Such controllers may be
found in various BCSRs (Board's FPGAs used to control board's
switches, LEDs, chip-selects, Ethernet/USB PHY power, etc).

So far we support only 1-byte GPIO banks. Support for other widths may
be implemented when/if needed.

p.s.
To avoid "made up" compatible entries (like compatible = "simple-gpio"),
boards must call simple_gpiochip_init() to pass the compatible string.

SOCs.

powerpc: Remove old Makefile workaround for arch/ppc

2008-10-12T23:56:18+00:00

There is an old workaround in the sysdev/Makefile for dealing
with arch/ppc vs. arch/powerpc compiles.  This is no longer
needed as arch/ppc is dead.

powerpc: Split-out common MSI bitmap logic into msi_bitmap.c

2008-08-20T06:34:57+00:00

There are now two almost identical implementations of an MSI bitmap
allocator, one in mpic_msi.c and the other in fsl_msi.c.

Merge them together and put the result in msi_bitmap.c.  Some of the
MPIC bits will remain to provide a nicer interface for the MPIC users.

In the process we fix two buglets.  The first is that the allocation
routines, now msi_bitmap_alloc_hwirqs(), returned an unsigned result,
even though they use -1 to indicate allocation failure.  Although all
the callers were checking correctly, it is much better for the routine
to just return an int.  At least until someone wants > ~2 billion MSIs.

The second buglet is that the device tree reservation logic only
allowed power-of-two reservations.  AFAICT that didn't effect any
existing code but it's nicer if we can reserve arbitrary irqs from MSI
use.

We also add some selftests, which exposed the two buglets and now test
for them, as well as some basic sanity tests.  The tests are only built
when CONFIG_DEBUG_KERNEL=y.

powerpc: Remove use of CONFIG_PPC_MERGE

2008-08-04T03:18:17+00:00

Now that arch/ppc is gone and CONFIG_PPC_MERGE is always set, remove
the dead code associated with !CONFIG_PPC_MERGE from arch/powerpc
and include/asm-powerpc.

powerpc/QE: switch to the cpm_muram implementation

2008-06-10T16:11:21+00:00

This is very trivial patch. We're transitioning to the cpm_muram_*
calls. That's it.

Less trivial changes:
- BD_SC_* defines were defined in the cpm.h and qe.h, so to avoid redefines
  we remove BD_SC from the qe.h and use cpm.h along with cpm_muram_*
  prototypes;
- qe_muram_dump was unused and thus removed;
- added some code to the cpm_common.c to support legacy QE bindings
  (data-only node name).
- For convenience, define qe_* calls to cpm_*. So drivers need not to be
  changed.
