* Fix linker scripts: add NOLOAD atribute to .bss/.sbss sectionsWolfgang Denk2008-01-12-19/+19
| | | | | | | | | | | | | | | | | | | With recent toolchain versions, some boards would not build because or errors like this one (here for ocotea board when building with ELDK 4.2 beta): ppc_4xx-ld: section .bootpg [fffff000 -> fffff23b] overlaps section .bss [fffee900 -> fffff8ab] For many boards, the .bss section is big enough that it wraps around at the end of the address space (0xFFFFFFFF), so the problem will not be visible unless you use a 64 bit tool chain for development. On some boards however, changes to the code size (due to different optimizations) we bail out with section overlaps like above. The fix is to add the NOLOAD attribute to the .bss and .sbss sections, telling the linker that .bss does not consume any space in the image. Signed-off-by: Wolfgang Denk <wd@denx.de>

| * ppc4xx: Update Katmai/44x_spd_ddr2.c code for optimal DDR2 setupStefan Roese2008-01-05-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | On Katmai the complete auto-calibration somehow doesn't seem to produce the best results, meaning optimal values for RQFD/RFFD. This was discovered by GDA using a high bandwidth scope, analyzing the DDR2 signals. GDA provided a fixed value for RQFD, so now on Katmai "only" RFFD is auto-calibrated. This patch also adds RDCC calibration as mentioned on page 7 of the AMCC PowerPC440SP/SPe DDR2 application note: "DDR1/DDR2 Initialization Sequence and Dynamic Tuning" Signed-off-by: Stefan Roese <sr@denx.de>

| | | | | | | | 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 Roese2007-12-06-8/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Add AMCC Kilauea/Haleakala NAND booting supportStefan Roese2007-11-03-1/+148
| | | | | | | This patch adds NAND booting support for the AMCC 405EX(r) eval boards. Again, only one image supports both targets. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Add CONFIG_4xx_DCACHE compile options to enable cached SDRAMStefan Roese2007-10-31-0/+4
| | | | | | | | | | | | | | This patch adds the CONFIG_4xx_DCACHE options to some SDRAM init files and to the Sequoia TLB init code. Now the cache can be enabled on 44x boards by defining CONFIG_4xx_DCACHE in the board config file. This option will disappear, when more boards use is successfully and no more known problems exist. This is tested successfully on Sequoia and Katmai. The only problem that needs to be fixed is, that USB is not working on Sequoia right now, since it will need some cache handling code too, similar to the 4xx EMAC driver.

* ppc4xx: Add initial AMCC Haleakala PPC405EXr eval board supportStefan Roese2007-10-31-3/+33
| | | | | | | | | | 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>
* 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!

| | | | | | | | | | 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>
* ppc4xx: Fix incorrect 33/66MHz PCI clock log-message on Sequoia & YosemiteStefan Roese2007-10-15-5/+9
| | | | | | | | | | | 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>

* 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.
