ppc4xx: Move ppc4xx headers to powerpc include directory This patch moves some ppc4xx related headers from the common include directory (include/) to the powerpc specific one (arch/powerpc/include/asm/). This way to common include directory is not so cluttered with files. Signed-off-by: Stefan Roese <sr@denx.de>

ppc4xx: Make 440SPe PCIe code more generic to use on different 4xx PPCs (1) This patch is the first patch of a series to make the 440SPe PCIe code usable on different 4xx PPC platforms. In preperation for the new 405EX which is also equipped with PCIe interfaces. (1) This patch renames the files from 440spe_pcie to 4xx_pcie Signed-off-by: Stefan Roese <sr@denx.de>

ppc4xx: Fix msg "initialization as root-complex failed" upon PCIe scan This message is printed upon PCIe bus scan, not only upon error, but also if no PCIe device is detected at all. Since this is not an error, let's remove this message in this case. We already have the message "link is not up." if there is no PCIe device present.

ppc4xx: Enable hardware-fix for PCI/DMA errata on AMCC 440SP/SPe boards 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>
