| * ppc4xx: Change LWMON5 to not use OCM for init-ram and POST anymoreStefan Roese2008-01-09-3/+1
| | | | | | | | | | | | | | This patch configures the LWMON5 port to use d-cache as init-ram and the unused GPT0_COMP6 as POST WORD storage. Signed-off-by: Stefan Roese <sr@denx.de>
* | 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>
* Add definitions for 440EPx/GRx SDRAM controller to ppc440.hLarry Johnson2007-12-27-48/+466
| | | | | | | | | This patch adds the Denali SDRAM controller definitions to "ppc440.h". It also fixes two typos in the definitions, so the board-specific "sdram.h" files containing these definitions are also fixed to avoid compiler warnings. Signed-off-by: Larry Johnson <lrj@acm.org>
* 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. 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>

| | | | | | | | | | 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>

* | [PATCH] Speed optimization of AMCC Sequoia/Rainier DDR2 setupStefan Roese2007-03-06-8/+8
|/ | | | | | | | | | | | | | 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.
