powerpc: Remove arch/ppc and include/asm-ppc

2008-06-10T11:40:22+00:00

All the maintained platforms are now in arch/powerpc, so the old
arch/ppc stuff can now go away.

[PPC] Remove 85xx from arch/ppc

2008-01-28T14:33:10+00:00

85xx exists in arch/powerpc as well as cuImage support to boot from
a u-boot that doesn't support device trees.

[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).

POWERPC: Get rid of remapping the whole immr

2006-09-21T18:37:58+00:00

The stuff below cleans up the code attempting to remap the whole cpm2_immr
early, as well as places happily assuming that fact. This is more like the 2.4
legacy stuff, and is at least confusing and unclear now.

To keep the world comfortable, a new mechanism is introduced: before accessing
specific immr register/register set, one needs to map it, using cpm2_map(),
for instance, access to CPM command register will look like
	volatile cpm_cpm2_t *cp = cpm2_map(im_cpm);
keeping the code clear, yet without "already defined somewhere" cpm2_immr.

So far, unmapping code is not implemented, but it's not a big deal to add it,
if the whole idea makes sense.

POWERPC: Move generic cpm2 stuff to powerpc

2006-09-21T18:18:53+00:00

This moves the cpm2 common code and PIC stuff to the powerpc. Most of the files
were just copied from ppc/, with minor tuning to make it compile, and, subsequently, work.

[PATCH] ppc32: board-specific part of fs_enet update

2006-08-19T21:44:31+00:00

This contains board-specific portion to respect driver changes (for 8272ads ,
885ads and 866ads).  Altered platform_data structures as well as initial setup
routines relevant to fs_enet.

Changes to the mpc8560ads ppc/ code are also introduced, but mainly as
reference, since the entire board support is going to appear in arch/powerpc.

[PATCH] ppc32 CPM_UART: Fixed break send on SCC

2006-05-03T13:06:43+00:00

SCC uart sends a break sequence each time it is stopped with the
CPM_CR_STOP_TX command. That means that each time an application closes the
serial device, a break is transmitted. To fix this, graceful tx stop is
issued for SCC.

[PATCH] ppc32: ppc_sys fixes for 8xx and 82xx

2005-10-29T04:49:29+00:00

This patch fixes a numbers of issues regarding to that both 8xx and 82xx
began to use ppc_sys model:
	- Platform is now identified by default deviceless SOC, if no
BOARD_CHIP_NAME is specified in the bard-specific header. For the list
of supported names refer to (arch/ppc/syslib/) mpc8xx_sys.c and
mpc82xx_sys.c for 8xx and 82xx respectively.
	- Fixed a bug in identification by name - if the name was not found,
it returned -1 instead of default deviceless ppc_spec.
	- fixed devices amount in the 8xx platform system descriptions
