* ppc4xx: Fixed offset of refresh rate type for Bamboo on-board DDR SDRAMEugene O'Brien2007-10-31-2/+2
| | | | | | | | | | | | | This patch also adds a note to the fixed DDR setup for Bamboo NAND booting: Note: As found out by Eugene O'Brien <eugene.obrien@advantechamt.com>, the fixed DDR setup has problems (U-Boot crashes randomly upon TFTP), when the DIMM modules are still plugged in. So it is recommended to remove the DIMM modules while using the NAND booting code with the fixed SDRAM setup!

* ppc4xx: Rework of 4xx serial driver (2)Stefan Roese2007-10-31-250/+0
| | | | | | | | | | Change all linker scripts to reference the changed driver name 4xx_uart.o. Note: In most cased all these explicit referencing of these object files in the linker scripts is not neccessary. Only for manually embedded environment into the U-Boot image, which is not done is most cases. Signed-off-by: Stefan Roese <sr@denx.de>

| | | | | | | | | | 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: Fix size setup in Kilauea DDR2 init routineStefan Roese2007-10-31-26/+26
| | | | | | | | | The size was initilized wrong. Instead of 256MB, the DDR2 controller was setup to 512MB. Now the correct values is used. This patch also does a little cleanup and adds a comment here. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Dynamic configuration of 4xx PCIe mode as root or endpoint modeStefan Roese2007-10-31-104/+100
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Enable device tree support (fdt) on Kilauea per defaultStefan Roese2007-10-31-0/+14
| | | | | | | | | | | | | This patch enables the fdt support on the AMCC Kilauea eval board. Additionally now EBC ranges fdt fixup is included to support NOR FLASH mapping via the Linux physmap_of driver. This Kilauea port now support booting arch/ppc and arch/powerpc Linux kernels. The default environment "net_nfs" is for arch/ppc and "net_nfs_fdt" is for arch/powerpc. In the long run, arch/ppc support will be removed. Signed-off-by: Stefan Roese <sr@denx.de>

* ppc4xx: Fix bug in I2C bootstrap values for Sequoia/RainierStefan Roese2007-10-15-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The I2C bootstrap values that can be setup via the "bootstrap" command, were setup incorrect regarding the generation of the internal sync PCI clock. The values for PLB clock == 133MHz were slighly incorrect and the values for PLB clock == 166MHz were totally incorrect. This could lead to a hangup upon booting while PCI configuration scan. This patch fixes this issue and configures valid PCI divisor values for the sync PCI clock, with respect to the provided external async PCI frequency. Here the values of the formula in the chapter 14.2 "PCI clocking" from the 440EPx users manual: AsyncPCICLK - 1MHz <= SyncPCIClk <= (2 * AsyncPCIClk) - 1MHz 33MHz async PCI frequency: PLB = 133: => 32 <= 44.3 <= 65 (div = 3) PLB = 166: => 32 <= 55.3 <= 65 (div = 3) 66MHz async PCI frequency: PLB = 133: => 65 <= 66.5 <= 132 (div = 2) PLB = 166: => 65 <= 83 <= 132 (div = 2) Signed-off-by: Stefan Roese <sr@denx.de>

| | | | | | | | | | | The BCSR status bit for the 66MHz PCI operation was correctly addressed (MSB/LSB problem). Now the correct currently setup PCI frequency is displayed upon bootup. This patch also fixes this problem on Rainier & Yellowstone, since these boards use the same souce code as Sequoia & Yosemite do. Signed-off-by: Stefan Roese <sr@denx.de>

* [PPC440SPe] Improve PCIe configuration space accessGrzegorz Bernacki2007-09-07-20/+22
| | | | | | | | | | | | | - 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.

* ppc4xx: (Re-)Enable CONFIG_PCI_PNP on AMCC 440EPx SequoiaGary Jennejohn2007-08-31-0/+3
| | | | | | | | | | | | | | | | | | | | | The 440EPx has a problem when the PCI_CACHE_LINE_SIZE register is set to non-zero, because it doesn't support MRM (memory-read- multiple) correctly. We now added the possibility to configure this register in the board config file, so that the default value of 8 can be overridden. Here the details of this patch: o drivers_pci_auto.c: introduce CFG_PCI_CACHE_LINE_SIZE to allow board-specific settings. As an example the sequoia board requires 0. Idea from Stefan Roese <sr@denx.de>. o board/amcc/sequoia/init.S: add a TLB mapping at 0xE8000000 for the PCI IO-space. Obtained from Stefan Roese <sr@denx.de>. o include/configs/sequoia.h: turn CONFIG_PCI_PNP back on and set CFG_PCI_CACHE_LINE_SIZE to 0.

* | [PATCH] Run new sequoia boards with an EBC speed of 83MHzJeffrey Mann2007-05-16-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because the Sequoia board does not boot with an EBC faster than 66MHz, the clock divider are changed after the initial boot process. This allows for maximum clocking speeds to be achieved on newer boards. Sequoia boards with 666.66 MHz processors require that the EBC divider be set to 3 in order to start the initial boot process at a slower EBC speed. After the initial boot process, the divider can be set back to 2, which will cause the boards to run at 83.333MHz. This is backward compatible with boards with 533.33 MHz processors, as these boards will already be set with an EBC divider of 2. Signed-off-by: Jeffrey Mann <mannj@embeddedplanet.com>
