* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Introduced dedicated switches for building 440 and 405 images required for 440-specific machine instructions like 'rfmci' etc. - Exception vectors moved to the proper location (_start moved away from the critical exception handler space, which it occupied) - CriticalInput now serviced (with default handler) - MachineCheck properly serviced (added a dedicated handler and return subroutine) - Overall cleanup of exceptions declared with STD_EXCEPTION macro (unused, unhandled and those not relevant for 4xx were eliminated) - Eliminated Linux leftovers, removed dead code Signed-off-by: Grzegorz Bernacki <gjb@semihalf.com> Signed-off-by: Rafal Jaworowski <raj@semihalf.com> 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.
