ppc4xx: Move ppc4xx headers to powerpc include directory

2010-09-23T07:02:05+00:00

This patch moves some ppc4xx related headers from the common include
directory (include/) to the powerpc specific one
(arch/powerpc/include/asm/). This way to common include directory is not
so cluttered with files.

common: delete CONFIG_SYS_64BIT_VSPRINTF and CONFIG_SYS_64BIT_STRTOUL

2009-12-08T21:14:07+00:00

There is more and more usage of printing 64bit values,
so enable this feature generally, and delete the
CONFIG_SYS_64BIT_VSPRINTF and CONFIG_SYS_64BIT_STRTOUL
defines.

ppc4xx: Add function to check and dynamically change PCI sync clock

2009-10-23T14:04:36+00:00

PPC440EP(x)/PPC440GR(x):
In asynchronous PCI mode, the synchronous PCI clock must meet
certain requirements. The following equation describes the
relationship that must be maintained between the asynchronous PCI
clock and synchronous PCI clock. Select an appropriate PCI:PLB
ratio to maintain the relationship:

AsyncPCIClk - 1MHz <= SyncPCIclock <= (2 * AsyncPCIClk) - 1MHz

This patch now adds a function to check and reconfigure the sync
PCI clock to meet this requirement. This is in preparation for
some AMCC boards (Sequoia/Rainier and Yosemite/Yellowstone) using this
function to not violate the PCI clocking rules.

ppc4xx: respect 80-chars per line in ppc*.h files

2009-10-07T07:15:30+00:00

After running checkstyle.pl on the three previous patches I noted that in
the *.h files there were a lot of long lines. This patch solves this problem.

ppc4xx: Big cleanup of PPC4xx defines

2009-09-11T08:35:58+00:00

This patch cleans up multiple issues of the 4xx register (mostly
DCR, SDR, CPR, etc) definitions:

- Change lower case defines to upper case (plb4_acr -> PLB4_ACR)
- Change the defines to better match the names from the
  user's manuals (e.g. cprpllc -> CPR0_PLLC)
- Removal of some unused defines

Please test this patch intensive on your PPC4xx platform. Even though
I tried not to break anything and tested successfully on multiple
4xx AMCC platforms, testing on custom platforms is recommended.

Dual-license IBM code contributions

2009-08-09T21:15:33+00:00

It was brought to our attention that U-Boot contains code derived from the
IBM OpenBIOS source code originally provided with some of the older PowerPC
4xx development boards.  As a result, the original license of this code has
been carried in the various files for a number of years in the U-Boot project.

IBM is dual-licensing the IBM code contributions already present in U-Boot
under either the terms of the GNU General Public License version 2, or the
original code license already present.

ppc4xx: Move definition for PPC4xx NAND FLASH controller to header

2009-05-23T10:51:39+00:00

This patch moves the definition for the PPC4xx NAND FLASH controller
(NDFC) CONFIG_NAND_NDFC into include/ppc4xx.h. This is needed for the
upcoming fix for the ECC byte ordering of the NDFC driver.

ppc4xx: Add routine to retrieve CPU number

2008-10-21T15:34:56+00:00

Provide a weak defined routine to retrieve the CPU number for
reference boards that have multiple CPU's.  Default behavior
is the existing single CPU print output.  Reference boards with
multiple CPU's need to provide a board specific routine.
See board/amcc/arches/arches.c for an example.
