* ppc4xx: Add basic support for AMCC 460EX/460GT (3/5)Stefan Roese2008-03-15-1/+78
| | | | | | This patch adds basic support for the AMCC 460EX/460GT PPC's. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Enable 405EX PCIe UTL register configurationStefan Roese2007-11-16-0/+2
| | | | | | | | Till now the UTL registers on 405EX were not initialized but left with their default values. This patch new initializes some of the UTL registers on 405EX. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Add PCIe endpoint support on Kilauea (405EX)Stefan Roese2007-10-31-3/+8
| | | | | | | | | | | | This patch adds endpoint support for the AMCC Kilauea eval board. It can be tested by connecting a reworked PCIe cable (only 1x lane singles connected) to another root-complex. In this test setup, a 64MB inbound window is configured at BAR0 which maps to 0 on the PLB side. So accessing this BAR0 from the root-complex will access the first 64MB of the SDRAM on the PPC side.

* ppc4xx: Dynamic configuration of 4xx PCIe mode as root or endpoint modeStefan Roese2007-10-31-0/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* ppc4xx: 4xx_pcie: More general cleanup and 405EX PCIe support addedStefan Roese2007-10-31-12/+19

* ppc4xx: Make 440SPe PCIe code more generic to use on different 4xx PPCs (3)Stefan Roese2007-10-31-2/+99
| | | | | | | | | | | | | | | (3) This patch introduces macros like SDRN_PESDR_DLPSET(port) to access the SDR registers of the PCIe ports. This makes the overall design clearer, since it removed a lot of switch statements which are not needed anymore. Also, the functions ppc4xx_init_pcie_rootport() and ppc4xx_init_pcie_entport() are merged into a single function ppc4xx_init_pcie_port(), since most of the code was duplicated. This makes maintainance and porting to other 4xx platforms easier. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Make 440SPe PCIe code more generic to use on different 4xx PPCs (2)Stefan Roese2007-10-31-9/+8
| | | | | | | | | | | 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>
* ppc4xx: Make 440SPe PCIe code more generic to use on different 4xx PPCs (1)Stefan Roese2007-10-31-0/+174
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. (1) This patch renames the files from 440spe_pcie to 4xx_pcie Signed-off-by: Stefan Roese <sr@denx.de>
