[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] 8xx: Remove sysdev/commproc.h

2008-01-28T14:31:02+00:00

Move cpm1 specific prototypes to asm/commproc.h and mpc8xx specific
prototypes to asm/mpc8xx.h. Adjust includes accordingly. Remove now
unneeded sysdev/commproc.h.

[POWERPC] 8xx: Remove unused m8xx_cpm_hostalloc/free/dump()

2008-01-28T14:30:59+00:00

m8xx_cpm_hostalloc is still defined in commproc.c, but no users are left
in the kernel tree. m8xx_cpm_hostfree and m8xx_cpm_hostdump are only
defined in the headers. Remove this dead code.

[POWERPC] Move CPM command handling into the cpm drivers

2007-12-14T04:47:16+00:00

This patch moves the CPM command handling into commproc.c
for CPM1 and cpm2_common.c. This is yet another preparation
to get rid of drivers accessing the CPM via the global cpmp.

[POWERPC] Add support for PORTA and PORTB odr registers

2007-12-14T04:46:42+00:00

PORTA and PORTB have odr registers, as well. However, the PORTB odr
register is only 16bit.

[POWERPC] cpm: Describe multi-user ram in its own device node.

2007-10-04T20:47:05+00:00

The way the current CPM binding describes available multi-user (a.k.a.
dual-ported) RAM doesn't work well when there are multiple free regions,
and it doesn't work at all if the region doesn't begin at the start of
the muram area (as the hardware needs to be programmed with offsets into
this area).  The latter situation can happen with SMC UARTs on CPM2, as its
parameter RAM is relocatable, u-boot puts it at zero, and the kernel doesn't
support moving it.

It is now described with a muram node, similar to QE.  The current CPM
binding is sufficiently recent (i.e. never appeared in an official release)
that compatibility with existing device trees is not an issue.

The code supporting the new binding is shared between cpm1 and cpm2, rather
than remain separated.  QE should be able to use this code as well, once
minor fixes are made to its device trees.

[POWERPC] 8xx: Add pin and clock setting functions.

2007-10-04T01:36:36+00:00

These let board code set up pins and clocks without having to
put magic numbers directly into the registers.

The clock function is mostly duplicated from the cpm2 version;
hopefully this stuff can be merged at some point.

[POWERPC] 8xx: Infrastructure code cleanup.

2007-10-04T01:36:35+00:00

1. Keep a global mpc8xx_immr mapping, rather than constantly
creating temporary mappings.
2. Look for new fsl,cpm1 and fsl,cpm1-pic names.
3. Always reset the CPM when not using the udbg console;
this is required in case the firmware initialized a device
that is incompatible with one that the kernel is about to
use.
4. Remove some superfluous casts and header includes.
5. Change a usage of IMAP_ADDR to get_immrbase().
6. Use phys_addr_t, not uint, for dpram_pbase.
7. Various sparse-related fixes, such as __iomem annotations.
8. Remove mpc8xx_show_cpuinfo, which doesn't provide anything
useful beyond the generic cpuinfo handler.
9. Move prototypes for 8xx support functions from board files
to sysdev/commproc.h.

[POWERPC] Fix copy'n'paste typo in commproc.c

2007-09-28T15:25:16+00:00

The powerpc version of commproc.c exports cpm_dpram_addr twice
and cpm_dpram_phys not at all due to a typo. This patch fixes this
problem.
