* ppc4xx: Rework of 4xx serial driver (1)Stefan Roese2007-10-31-208/+243
| | | | | | | | | This patch starts the rework of the PPC4xx serial driver. First we split the file into two seperate files, one 4xx_uart.c with the 405/440 UART handling code and the other one iop480_uart.c with the UART code for the PLX-Tech IOP480 PPC (PPC403 based).

* ppc4xx: Consolidate some of the 405 and 440 macros/structs into 4xxStefan Roese2007-10-31-34/+31
| | | | | | | | | | 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: Add PCIe endpoint support on Kilauea (405EX)Stefan Roese2007-10-31-10/+21
| | | | | | | | | | | | 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 Roese2007-10-31-1/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Change CFG_PCIE_MEMSIZE to 128MB on Yucca & KatmaiStefan Roese2007-10-31-1/+24
| | | | | | | | | | | | | | | | | 128MB seems to be the smallest possible value for the memory size for on PCIe port. With this change now the BAR's of the PCIe cards are accessible under U-Boot. One big note: This only works for PCIe port 0 & 1. For port 2 this currently doesn't work, since the base address is now 0xc0000000 (0xb0000000 + 2 * 0x08000000), and this is already occupied by CFG_PCIE0_CFGBASE. But solving this issue for port 2 would mean to change the base addresses completely and this change would have too much impact right now. This patch adds debug output to the 4xx pcie driver too.

* ppc4xx: Make 440SPe PCIe code more generic to use on different 4xx PPCs (3)Stefan Roese2007-10-31-419/+223
| | | | | | | | | | | | | | | (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>

* fix pxa255_idp boardMarcel Ziswiler2007-10-23-39/+42
| | | | | | | | | | | | | | | | | | | | | | | The pxa255_idp being an old unmaintained board showed several issues: 1. CONFIG_INIT_CRITICAL was still defined. 2. Neither CONFIG_MAC_PARTITION nor CONFIG_DOS_PARTITION was defined. 3. Symbol flash_addr was undeclared. 4. The boards lowlevel_init function was still called memsetup. 5. The TEXT_BASE was still 0xa3000000 rather than 0xa3080000. 6. Using -march=armv5 instead of -march=armv5te resulted in lots of 'target CPU does not support interworking' warnings on recent compilers. 7. The PXA's serial driver redefined FFUART, BTUART and STUART used as indexes rather than the register definitions from the pxa-regs header file. Renamed them to FFUART_INDEX, BTUART_INDEX and STUART_INDEX to avoid any ambiguities. 8. There were several redefinition warnings concerning ICMR, OSMR3, OSCR, OWER, OIER, RCSR and CCCR in the PXA's assembly start file. 9. The board configuration file was rather outdated. 10. The part header file defined the vendor, product and revision arrays as unsigned chars instead of just chars in the block_dev_desc_t structure. Signed-off-by: Marcel Ziswiler <marcel@ziswiler.com>
* 86xx: Allow for fewer DDR slots per memory controller.Jon Loeliger2007-10-16-9/+21
| | | | | | | | | | | | | As a direct correlation exists between DDR DIMM slots and SPD EEPROM addresses used to configure them, use the individually defined SPD_EEPROM_ADDRESS* values to determine if a DDR DIMM slot should have its SPD configuration read or not. Effectively, this now allows for 1 or 2 DIMM slots per memory controller. Signed-off-by: Jon Loeliger <jdl@freescale.com>
