The MPC8572 has a 4-bit wide PORDEVSR IO_SEL field. Other MPC85xx processors have a 3-bit wide IO_SEL field but have the most significant bit is wired to 0 so this change should not affect them. Signed-off-by: NPeter Tyser <ptyser@xes-inc.com>

Converted MPC8610HCPD, MPC8641HPCN, and SBC8641D to use fsl_pci_setup_inbound_windows() and ft_fsl_pci_setup(). With these changes the board code is a bit smaller and we get dma-ranges set in the device tree for these boards.

The PCI address should be setting piwar/piwbear and the system address should be setting pitar. * Removed masking of addresses to allow for system address to support system address & PCI address >32-bits * Set PIWBEAR & POTEAR to allow for full 64-bit PCI addresses * Respect the PCI_REGION_PREFETCH for inbound windows Signed-off-by: NKumar Gala <galak@kernel.crashing.org> Signed-off-by: NAndrew Fleming-AFLEMING <afleming@freescale.com>

The 8572 DDR erratum1: DDR controller may enter an illegal state when operating in 32-bit bus mode with 4-beat bursts. Description: When operating with a 32-bit bus, it is recommended that DDR_SDRAM_CFG[8_BE] is cleared when DDR2 memories are used. This forces the DDR controller to use 4-beat bursts when communicating to the DRAMs. However, an issue exists that could lead to data corruption when the DDR controller is in 32-bit bus mode while using 4-beat bursts. Projected Impact: If the DDR controller is operating in 32-bit bus mode with 4-beat bursts, then the controller may enter into a bad state. All subsequent reads from memory is corrupted. Four-beat bursts with a 32-bit bus only is used with DDR2 memories. Therefore, this erratum does not affect DDR3 mode. Work Arounds: To work around this issue, software must set DEBUG_1[31] in DDR memory mapped space (CCSRBAR offset + 0x2f00 for DDR_1 and CCSRBAR offset + 0x6f00 for DDR_2). Currenlty, the code is using incorrect register DDR_SDRAM_CFG_2 as condition, but it should be DDR_SDRAM_CFG register. Signed-off-by: NDave Liu <daveliu@freescale.com>

As "ppc44x: Unification of virtex5 pp440 boards" did for the xilinx ppc440 boards, this patch presents a common architecture for all the xilinx ppc405 boards. Any custom xilinx ppc405 board can be added very easily with no code duplicity. This patch also adds a simple generic board, that can be used on almost any design with xilinx ppc405 replacing the file ppc405-generic/xparameters.h This patch is prepared to work with the latest version of EDK (10.1) Signed-off-by: NRicardo Ribalda Delgado <ricardo.ribalda@uam.es> Signed-off-by: NStefan Roese <sr@denx.de>

Since the new autocalibration still has some problems on some Kilauea boards with 200MHz DDR2 frequency we disable the autocalibration and use the hardcoded values as done before. This seems to work reliably on all known DDR2 frequencies. After the autocalibration issue is fixed we will enable it again. Signed-off-by: NStefan Roese <sr@denx.de>

Though NAND chip is replaceable on the MPC837XE-MDS boards, the current settings don't work with the default chip on the board. Nevertheless Freescale's U-Boot sets the option register correctly, so I just dumped the register from the working u-boot. My guess is that the old settings were applicable for some pilot boards, not found in the production. This patch also enables FSL ELBC driver so that we could access the NAND storage in the u-boot. The NAND support costs about 45KB, so the u-boot no longer fits into two 128KB NOR flash sectors, thus we also have to adjust environment location: add another 128KB to the monitor length. Signed-off-by: NAnton Vorontsov <avorontsov@ru.mvista.com> It is due to hardware design and logic defect, that is the I/O[0:7] of NAND chip is connected to LAD[7:0], so when the NAND chip connected to nLCS3, you have to set up the OR3[BCTLD] = '1' for normal operation, otherwise it will have bus contention due to the pin 48/25 of U60 is enabled. Setup the OR3[BCTLD] = '1' , that meaning the LBCTL is not asserted upon access to the NAND chip, keep the default state.

The MPC837xE-MDS board's CPLD can auto-detect if the board is on the PIB, standalone or acting as a PCI agent. User's Guide says: - When the CPLD recognizes its location on the PIB it automatically configures RCW to the PCI Host. - If the CPLD fails to recognize its location then it is automatically configured as an Agent and the PCI is configured to an external arbiter. This sounds good. Though in the standalone setup the CPLD sets PCI_HOST flag (it's ok, we can't act as PCI agents since we receive CLKIN, not PCICLK), but the CPLD doesn't set the ARBITER_ENABLE flag, and without any arbiter bad things will happen (here the board hangs during any config space reads). In this situation we must disable the PCI. And in case of anybody really want to use an external arbiter, we provide "pci_external_aribter" environment variable.

MPC837xE specs says that SerDes1 has: — Two lanes running x1 SGMII at 1.25 Gbps; — Two lanes running x1 SATA at 1.5 or 3.0 Gbps. And for SerDes2: — Two lanes running x1 PCI Express at 2.5 Gbps; — One lane running x2 PCI Express at 2.5 Gbps; — Two lanes running x1 SATA at 1.5 or 3.0 Gbps. The spec also explicitly states that PEX options are not valid for the SD1. Nevertheless MPC8378 RDB and MDS boards configure the SD1 for PEX, which is wrong to do.

Currently 64M of LBC SDRAM are mapped at 0xF0000000 which makes it difficult to use (b/c then the memory is discontinuous and there is quite big memory hole between the DDR/SDRAM regions). This patch reworks LBC SDRAM setup so that now we dynamically place the LBC SDRAM near the DDR (or at 0x0 if there isn't any DDR memory). With this patch we're able to: - Boot without external DDR memory; - Use most "DDR + SDRAM" setups without need to support for sparse/discontinuous memory model in the software.
