* ppc4xx: Fix 460EX errata with CPU lockup upon high AHB trafficStefan Roese2008-06-30-0/+2
| | | | | | | | | | | | | | | This patch implements a fix provided by AMCC so that the lockup upon simultanious traffic on AHB USB OTG, USB 2.0 and SATA doesn't occur anymore: Set SDR0_AHB_CFG[A2P_INCR4] (bit 24) and clear SDR0_AHB_CFG[A2P_PROT2] (bit 25) for a new 460EX errata regarding concurrent use of AHB USB OTG, USB 2.0 host and SATA. This errata is not officially available yet. I'll update the comment to add the errata number later. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Consolidate PPC4xx SDRAM/DDR/DDR2 defines, part1Stefan Roese2008-06-03-896/+0
| | | | | | | | | | | | | | | | | | | This patch removes all SDRAM related defines from the PPC4xx headers ppc405.h and ppc440.h. This is needed since now some 405 PPC's use the same SDRAM controller as 440 systems do (like 405EX and 440SP). It also introduces new defines for the equipped SDRAM controller based on which PPC variant is used. There new defines are: used on 405GR/CR/EP and some Xilinx Virtex boards. used on 440GP/GX/EP/GR. used on 440EPx/GRx. used on 405EX/r/440SP/SPe/460EX/GT. Signed-off-by: Stefan Roese <sr@denx.de>
* Big white-space cleanup.Wolfgang Denk2008-05-21-1/+1
| | | | | | | | | | | This commit gets rid of a huge amount of silly white-space issues. Especially, all sequences of SPACEs followed by TAB characters get removed (unless they appear in print statements). Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de>

| | | | | | | | | | | | | | This patch adds support for the AMCC Glacier 460GT eval board. The main difference to the Canyonlands board are listed here: - 4 ethernet ports instead of 2 - no SATA port - no USB port Currently EMAC2+3 are not working. This will be fixed in a later release.

* The patch introduces the alternative configuration of the log buffer for the ↵Yuri Tikhonov2008-03-18-0/+2
| | | | | | | | | | | | | | lwmon5 board: the storage for the log-buffer itself is OCM(on-chip memory), the log-buffer header is moved to six GPT registers (PPC440EPX_GPT0_COMP1, ..., PPC440EPX_GPT0_COMP5). To enable this, alternative, configuration the U-Boot board configuration file for lwmon5 includes the definitions of alternative addresses for header (CONFIG_ALT_LH_ADDR) and buffer (CONFIG_ALT_LB_ADDR). The Linux shall be configured with the CONFIG_ALT_LB_LOCATION option set, and has the BOARD_ALT_LH_ADDR and BOARD_ALT_LB_ADDR constants defined in the lwmon5 board-specific header (arch/ppc/platforms/4xx/lwmon5.h).

* | ppc4xx: Update Katmai/44x_spd_ddr2.c code for optimal DDR2 setupStefan Roese2008-01-05-2/+10
|/ | | | | | | | | | | | | | 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>

* 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.

|/ | | | | | | | | | | | | | As provided by the AMCC applications team, this patch optimizes the DDR2 setup for 166MHz bus speed. The values provided are also save to use on a "normal" 133MHz PLB bus system. Only the refresh counter setup has to be adjusted as done in this patch. For this the NAND booting version had to include the "speed.c" file from the cpu/ppc4xx directory. With this addition the NAND SPL image will just fit into the 4kbytes of program space. gcc version 4.x as provided with ELDK 4.x is needed to generate this optimized code.
