* ppc4xx: 405EX: Correctly enable USB pinsStefan Roese2007-12-08-10/+23
| | | | | | | | This patch selects the USB data pins in the 405EX GPIO and MFC (multi function control) registers. This is done for the AMCC Kilauea and Makalu eval boards. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Enable hardware-fix for PCI/DMA errata on AMCC 440SP/SPe boardsStefan Roese2007-12-06-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* ppc4xx: Correct UART input clock calculation and passing to fdtStefan Roese2007-10-31-0/+3
| | | | | | | | We now use a value in the gd (global data) structure for the UART input frequency, since the PPC4xx_SYS_INFO struct is always rewritten completely in get_sys_info(). Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Add initial AMCC Haleakala PPC405EXr eval board supportStefan Roese2007-10-31-0/+1
| | | | | | | | | | The Haleakala is nearly identical with the Kilauea eval board. The only difference is that the 405EXr only supports one EMAC and one PCIe interface. This patch adds support for the Haleakala board by using the identical image for Kilauea and Haleakala. The distinction is done by comparing the PVR. Signed-off-by: Stefan Roese <sr@denx.de>

* rtc: Add Xicor/Intersil X1205 RTC supportStefan Roese2007-10-31-0/+20
| | | | | | | | | | | | | This patch adds support for the Xicor/Intersil X1205 RTC used on the AMCC Makalu eval board. This driver is basically cloned from the Linux driver version (2.6.23). This patch also introduces the Linux bcd.h header for the BCD2BIN/ BIN2BCD conversions. In the future some of the other U-Boot RTC driver should be converted to also use this header instead of implementing their own local copy of these functions/macros.

* ppc4xx: Consolidate some of the 405 and 440 macros/structs into 4xxStefan Roese2007-10-31-151/+71
| | | | | | | | | | 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: Change inbound PCIe location for endpoint tests on KatmaiStefan Roese2007-10-31-1/+1
| | | | | | | | | | | | On Yucca & Katmai, the inbound memory map pointed to 0x4.0000.0000, which is the internal SRAM. Since I now ported and tested this endpoint mode on Kilauea successfully to map to 0 (SDRAM), I also changed this for Katmai. Yucca will stay at internal SRAM for now. Not sure if somebody relies on this setup. 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/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Roese2007-10-31-43/+3
| | | | | | | | | | | | | 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: 4xx_pcie: Change CFG_PCIE_MEMSIZE to 128MB on Yucca & KatmaiStefan Roese2007-10-31-2/+2
| | | | | | | | | | | | | | | | | 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: Rename 405gp_pci to 4xx_pci since its used on all 4xx platformsStefan Roese2007-10-31-0/+0
| | | | | | | | These files were introduced with the IBM 405GP but are currently used on all 4xx PPC platforms. So the name doesn't match the content anymore. This patch renames the files to 4xx_pci.c/h. Signed-off-by: Stefan Roese <sr@denx.de>
* 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>

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>
