[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] cpm2: Add cpm2_set_pin().

2007-10-04T16:02:18+00:00

This provides a generic way for board code to set up CPM pins, rather
than directly poking magic values into registers.

[POWERPC] cpm2: Infrastructure code cleanup.

2007-10-04T16:02:04+00:00

Mostly sparse fixes (__iomem annotations, etc); also, cpm2_immr
is used rather than creating many temporary mappings.

[POWERPC] cpm2: Fix off-by-one error in setbrg().

2007-09-10T21:02:09+00:00

The hardware adds one to the BRG value to get the divider, so it must
be subtracted by software.  Without this patch, characters will occasionally
be corrupted.

[POWERPC] Change rheap functions to use ulongs instead of pointers

2007-05-10T04:01:43+00:00

The rheap allocation functions return a pointer, but the actual value is based
on how the heap was initialized, and so it can be anything, e.g. an offset
into a buffer.  A ulong is a better representation of the value returned by
the allocation functions.

This patch changes all of the relevant rheap functions to use a unsigned long
integers instead of a pointer.  In case of an error, the value returned is
a negative error code that has been cast to an unsigned long.  The caller can
use the IS_ERR_VALUE() macro to check for this.

All code which calls the rheap functions is updated accordingly.  Macros
IS_MURAM_ERR() and IS_DPERR(), have been deleted in favor of IS_ERR_VALUE().

Also added error checking to rh_attach_region().

POWERPC: overhaul with cpm2_map mechanism

2006-09-21T18:38:05+00:00

Incorporating the new way of cpm2 immr access, introduced in the previous
patch, into CPM2 peripheral devices (fs_enet and cpm_uart). Both ppc and
powerpc approved working( real actions taken in powerpc only, ppc just
has a wrapper to keep init stuff consistent).
