* ppc4xx: Fix problem with board_eth_init() vs cpu_eth_init() on AMCC boardsStefan Roese2009-02-12-0/+1
| | | | | | | | Some AMCC eval boards do have a board_eth_init() function calling pci_eth_init(). These boards need to call cpu_eth_init() explicitly now with the new eth_init rework. Signed-off-by: Stefan Roese <sr@denx.de>

* ppc4xx: Cleanup Katmai & Yucca PCIe register usageStefan Roese2008-07-11-55/+7
| | | | | | | This patch cleans up the 440SPe PCIe register usage. Now only defines from the include/asm-ppc/4xx_pcie.h are used. Signed-off-by: Stefan Roese <sr@denx.de>

* Big white-space cleanup.Wolfgang Denk2008-05-21-15/+15
| | | | | | | | | | | This commit gets rid of a huge amount of silly white-space issues. Especially, all sequences of SPACEs followed by TAB characters get removed (unless they appear in print statements). Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de>
* ppc4xx: Enable hardware-fix for PCI/DMA errata on AMCC 440SP/SPe boardsStefan Roese2007-12-06-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enables the hardware-fix for the PCI/DMA errata's 19+22 by setting the FIXD bit in the SDR0_MFR register. Here a description of the symptoms: Problem Description ------------------------------ If a DMA is performed between memory and PCI with the DMA 1 Controller using prefetch, and as a result uses a special purpose buffer selected by the PCIXn Bridge Options 1 Register (PCIXn_BRDGOPT1[RBP7] - bits 31-29), the first part of the transfer sequence is performed twice. The PPC440SPe PCI Controller requests more data than was needed such that in the case of enforce memory protection, a host CPU exception can occur. No data is corrupted, because data transfer is stopped in the PCI Controller. Prefetch enable is specified by setting DMA Configuration Register (I2O0_DMAx_CFG[DXEPD] - bit 31) to 0. Behavior that may be observed in a running system --------------------------------------------------------------------------- 1. DMA performance is decreased because of the double access on the PCI bus interface. 2. If an illegal access to some address on the PCI bus is detected at the system level, a machine check or similar system error may occur. Workarounds Available ---------------------------------- 1. Do not program prefetch. Note that a prefetch command cannot be programmed without selecting a special purpose buffer. 2. To avoid crossing a physical boundary of the PCI slave device, add 512 bytes of address to the PCI address range. This patch was originally provided by Pravin M. Bathija <pbathija@amcc.com> from AMCC and slighly changed. Signed-off-by: Pravin M. Bathija <pbathija@amcc.com> Signed-off-by: Stefan Roese <sr@denx.de>

* ppc4xx: Consolidate some of the 405 and 440 macros/structs into 4xxStefan Roese2007-10-31-6/+0
| | | | | | | | | | This patch moves some common 4xx macros and the PPC405_SYS_INFO/ PPC440_SYS_INFO structure into the common ppc4xx.h header. Lot's of other macros are good candidates to be consolidated this way in the future. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Dynamic configuration of 4xx PCIe mode as root or endpoint modeStefan Roese2007-10-31-37/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for dynamic configuration of PCIe ports for the AMCC PPC4xx boards equipped with PCIe interfaces. These are the PPC440SPe boards Yucca & Katmai and the 405EX board Kilauea. This dynamic configuration is done via the "pcie_mode" environement variable. This variable can be set to "EP" or "RP" for endpoint or rootpoint mode. Multiple values can be joined via the ":" delimiter. Here an example: pcie_mode=RP:EP:EP This way, PCIe port 0 will be configured as rootpoint, PCIe port 1 and 2 as endpoint. Per default Yucca will be configured as: pcie_mode=RP:EP:EP Per default Katmai will be configured as: pcie_mode=RP:RP:REP Per default Kilauea will be configured as: pcie_mode=RP:RP Signed-off-by: Tirumala R Marri <tmarri@amcc.com> Signed-off-by: Stefan Roese <sr@denx.de>

| | | | | | | | | | | This patch is the first patch of a series to make the 440SPe PCIe code usable on different 4xx PPC platforms. In preperation for the new 405EX which is also equipped with PCIe interfaces. (2) This patch renames the functions from 440spe_ to 4xx_ with a little additional cleanup Signed-off-by: Stefan Roese <sr@denx.de>

* [PPC440SPe] PCIe environment settings for Katmai and YuccaGrzegorz Bernacki2007-09-07-0/+12
| | | | | | | | | | | | - 'pciconfighost' is set by default in order to be able to scan bridges behind the primary host/PCIe - 'pciscandelay' env variable is recognized to allow for user-controlled delay before the PCIe bus enumeration; some peripheral devices require a significant delay before they can be scanned (e.g. LSI8408E); without the delay they are not detected Signed-off-by: Grzegorz Bernacki <gjb@semihalf.com>
* [PPC440SPe] Improve PCIe configuration space accessGrzegorz Bernacki2007-09-07-4/+5
| | | | | | | | | | | | | - correct configuration space mapping - correct bus numbering - better access to config space Prior to this patch, the 440SPe host/PCIe bridge was able to configure only the first device on the first bus. We now allow to configure up to 16 buses; also, scanning for devices behind the PCIe-PCIe bridge is supported, so peripheral devices farther in hierarchy can be identified.

* Improve DIMM detection for AMCC Yucca 440SPe boardStefan Roese2006-08-29-7/+24
| | | | | | | | | | | | | | | Improved the memory DIMM detection for the Yucca 440SPe board for the case where a memory DIMM is falsely detected as present. This issue is seen on some AMCC Yucca 440SPe validation boards if only one 512MB memory DIMM is installed, i.e. DIMM slot 0 is populated and DIMM slot 1 is empty. In this case, U-Boot does not correctly detect that there is only one DIMM memory module installed and will falsely detect two DIMM memory modules are present and therefore U-Boot will not calculate the correct amount of total memory and u-boot will not booting up.
