2009-11-19ppc4xx: Consolidate pci_pre_init() functionStefan Roese
This patch removes the duplicted implementations of the pci_pre_init() function by introducing a weak default function for it. This weak default has a different implementation for some PPC variants. It can be overridden by a board specific version. Signed-off-by: Stefan Roese <sr@denx.de>
2009-10-23ppc4xx: Print PCI synchronous clock frequency upon bootupStefan Roese
Some 4xx variants (e.g. 440EP(x)/GR(x)) have an internal synchronous PCI clock. Knowledge about the currently configured value might be helpful. So let's print it out upon bootup. Signed-off-by: Stefan Roese <sr@denx.de>
2009-10-07ppc4xx: Add PPC405EX(r) Rev D supportStefan Roese
Unfortunately some Rev D PPC405EX/405EXr PVR's are identical with older 405EX(r) parts. Here a list: 0x12911475 - 405EX Rev D with Security *and* 405EX Rev A/B witout Sec 0x12911473 - 405EX Rev D without Security *and* 405EXr Rev A/B with Sec Since there are only a few older parts in the field, this patch now changes the PVR's above to represent the new Rev D versions.

2009-09-11ppc4xx: Big cleanup of PPC4xx definesStefan Roese
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. Signed-off-by: Stefan Roese <sr@denx.de>

2009-04-16ppc4xx: Add "booting from NAND" to 4xx NAND-booting targetsStefan Roese
This additional text in the bootup log helps to see if the board is configured for NAND-booting. Especially helpful for boards that can boot from NOR and NAND (e.g. most of the AMCC eval boards). Signed-off-by: Stefan Roese <sr@denx.de>

2008-10-21ppc4xx: Add routine to retrieve CPU numberAdam Graham
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.

2007-11-16ppc4xx: Enable 405EX PCIe UTL register configurationStefan Roese

2007-11-09ppc4xx: Make output a little shorter on I2C bootrom detectionStefan Roese
Most 4xx PPC capable of using an I2C bootrom for bootstrap setting already print a line with the information which I2C bootrom is used for bootstrap configuration. So we don't need this extra line with "I2C boot EEPROM en-/dis-abled". This patch also has a little code cleanup integrated. Signed-off-by: Stefan Roese <sr@denx.de>

This patch adds support for the new AMCC 405EZ PPC. It is in preparation for the AMCC Acadia board support. Please note that this Acadia/405EZ support is still in a beta stage. Still lot's of cleanup needed but we need a preliminary release now. Signed-off-by: Stefan Roese <sr@denx.de>
2007-02-02[PATCH] Correctly display PCI arbiter en-/disabled on some 4xx boardsStefan Roese
Previously the strapping DCR/SDR was read to determine if the internal PCI arbiter is enabled or not. This strapping bit can be overridden, so now the current status is read from the correct DCR/SDR register. Signed-off-by: Stefan Roese <sr@denx.de>

2005-11-27Changed PPC44x startup message (cpu info, speed...) to common style:Stefan Roese
On PPC44x platforms, the startup message generated in "cpu.c" only comprised the ppc type and revision but not additional informations like speed etc. Those speed infos where printed in the board specific code. This new implementation now prints all CPU infos in the common cpu specific code. No board specific code is needed anymore and therefore removed from all current 44x implementations.
