Mostly in and around irq handlers.

[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] Fix compile error if CONFIG_STX_GP3 is defined

2008-01-24T01:35:20+00:00

cpmux is need in all cases, having wrapped by the ifndef CONFIG_STX_GP3
was causing a compile error.

[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] 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] cpm_uart: Issue STOP_TX command before initializing console.

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

This prevents some bootloader/bootwrapper characters from being lost.

[POWERPC] cpm_uart: sparse fixes

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

Mostly a bunch of direct access to in/out conversions, plus a few
cast removals, __iomem annotations, and miscellaneous cleanup.

[POWERPC] cpm_uart: Be an of_platform device when CONFIG_PPC_CPM_NEW_BINDING is set.

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

The existing OF glue code was crufty and broken.  Rather than fix it,
it has been removed, and the serial driver now talks to the device tree
directly.

The non-CONFIG_PPC_CPM_NEW_BINDING code can go away once CPM platforms
are dropped from arch/ppc (which will hopefully be soon), and existing
arch/powerpc boards that I wasn't able to test on for this patchset get
converted (which should be even sooner).

[POWERPC] Fix cpm_uart driver for cpm1 machines

2007-09-28T15:26:30+00:00

in cpm_uart_cpm1.h, DPRAM_BASE is assigned an address derived from cpmp.
On ARC=ppc, this is a physical address with 1:1 DMA mapping which can't
be used for arithmetric compare operations with virtual addresses
returned by cpm_dpram_addr. This patch changes the assignment to use
cpm_dpram_addr as well, like in cpm_uart_cpm2.h.
