[POWERPC] fsl_lbc: implement few UPM routines

2008-04-17T06:01:38+00:00

Freescale UPM can be used to adjust localbus timings or to generate
orbitrary, pre-programmed "patterns" on the external Localbus signals.
This patch implements few routines so drivers could work with UPMs in
safe and generic manner.

So far there is just one user of these routines: Freescale UPM NAND
driver.

[POWERPC] 4xx: Add PPC4xx L2-cache support (440GX)

2008-03-26T12:27:54+00:00

This patch adds support for the 256k L2 cache found on some IBM/AMCC
4xx PPC's. It introduces a common 4xx SoC file (sysdev/ppc4xx_soc.c)
which currently "only" adds the L2 cache init code. Other common 4xx
stuff can be added later here.

The L2 cache handling code is a copy of Eugene's code in arch/ppc
with small modifications.

Tested on AMCC Taishan 440GX.

[POWERPC] CPM: Rename commproc to cpm1 and cpm2_common.c to cpm2.c

2008-01-28T14:31:05+00:00

Rename commproc.[ch] to cpm1.[ch] to be more consistent with cpm2. Also
rename cpm2_common.c to cpm2.c as suggested by Scott Wood. Adjust the
includes accordingly.

[POWERPC] Enable RTC for Ebony and Walnut (v2)

2008-01-25T13:07:26+00:00

This patch extends the Ebony and Walnut platform code to instantiate
the existing ds1742 RTC class driver for the DS1743 RTC/NVRAM chip
found on both those boards.  The patch uses a helper function to scan
the device tree and instantiate the appropriate platform_device based
on it, so it should be easy to extend for other boards which have mmio
mapped RTC chips.

Along with this, the device tree binding for the ds1743 chips is
tweaked, based on the existing DS1385 OF binding found at:
	http://playground.sun.com/1275/proposals/Closed/Remanded/Accepted/346-it.txt
Although that document covers the NVRAM portion of the chip, whereas
here we're interested in the RTC portion, so it's not entirely clear
if that's a good model.

This implements only RTC class driver support - that is /dev/rtc0, not
/dev/rtc, and the low-level get/set time callbacks remain
unimplemented.  That means in order to get at the clock you will
either need a modified version of hwclock which will look at
/dev/rtc0, or you'll need to configure udev to symlink rtc0 to rtc.

[POWERPC] Move RapidIO support code from arch/ppc

2008-01-24T01:35:15+00:00

Do just enough to move the RapidIO support code for 85xx over from arch/ppc
into arch/powerpc and make it still build.

[POWERPC] Add IPIC Kconfig option

[POWERPC] 4xx: PLB to PCI-X support

2007-12-23T19:12:20+00:00

This adds base support code for the 4xx PCI-X bridge. It also provides
placeholders for the PCI and PCI-E version but they aren't supported
with this patch.

The bridges are configured based on device-tree properties.

[POWERPC] pasemi: Implement MSI support

2007-12-20T05:15:23+00:00

Implement MSI support for PA Semi PWRficient platforms. MSI is done
through a special range of sources on the openpic controller, and they're
unfortunately breaking the usual concepts of how sources are programmed:

* The source is calculated as 512 + the value written into the MSI
  register
* The vector for this source is added to the source and reported
  through IACK

This means that for simplicity, it makes much more sense to just set the
vector to 0 for the source, since that's really the vector we expect to
see from IACK.

Also, the affinity/priority registers will affect 16 sources at a
time. To avoid most (simple) users from being limited by this, allocate
16 sources per device but use only one. This means that there's a total
of 32 sources.

If we get usage scenarions that need more sources, the allocator should
probably be revised to take an alignment argument and size, not just do
natural alignment.

Finally, since I'm already touching the MPIC names on pasemi, rename
the base one from the somewhat odd " PAS-OPIC  " to "PASEMI-OPIC".

[POWERPC] bestcomm: core bestcomm support for Freescale MPC5200

2007-10-16T23:09:34+00:00

This patch adds support for the core of the BestComm API
for the Freescale MPC5200(b). The BestComm engine is a
microcode-controlled / tasks-based DMA used by several
of the onchip devices.

Setting up the tasks / memory allocation and all common
low level functions are handled by this patch.
The specifics details of each tasks and their microcode
are split-out in separate patches.

This is not the official API, but a much cleaner one.
(hopefully)

[POWERPC] Don't build arch/powerpc/sysdev/dcr.c for ARCH=ppc kernels

dcr.c is an arch/powerpc only thing.  Compiling ppc405 arch/ppc kernels
