* Blackfin: linker scripts: force start.o and set initcode boundariesMike Frysinger2008-10-23-4/+24
| | | | | | | | Make sure that the start.o object is always the first object in our linker script regardless of configuration settings, and add some linker symbols so the ldr utility can properly locate the initcode when generating a LDR. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* mpc83xx: add ELBC NAND support for the MPC837XEMDS boardsAnton Vorontsov2008-10-21-3/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Anton 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.

* mpc83xx: fix PCI scan hang on the standalone MPC837xE-MDS boardsAnton Vorontsov2008-10-21-0/+47
| | | | | | | | | | | | | | | | | | | | | | | 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.

* mpc83xx: serdes: add forgotten shifts for rfcksAnton Vorontsov2008-10-21-6/+6
| | | | | | | | | | The rfcks should be shifted by 28 bits left. We didn't notice the bug because we were using only 100MHz clocks (for which rfcks == 0). Though, for SGMII we'll need 125MHz clocks.

* mpc83xx: fix serdes setup for the MPC8378E boardsAnton Vorontsov2008-10-21-2/+2
| | | | | | | | | | | | | | | | | | | | | | 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.

* mpc83xx: mpc8360emds: rework LBC SDRAM setupAnton Vorontsov2008-10-21-26/+38
| | | | | | | | | | | | | | | | | | | 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.

| * | ppc4xx: PPC44x MQ initializationStefan Roese2008-10-17-4/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Set the MQ Read Passing & MCIF Cycle limits to the recommended by AMCC values. This fixes the occasional 440SPe hard locking issues when the 440SPe's dedicated DMA engines are used (e.g. by the h/w accelerated RAID driver). Previously the appropriate initialization had been made in Linux, by the ppc440spe ADMA driver, which is wrong because modifying the MQ configuration registers after normal operation has begun is not supported and could have unpredictable results. Comment from Stefan: This patch doesn't change the resulting value of the MQ registers. It explicitly sets/clears all bits to the desired state which better documents the resulting register value instead of relying on pre-set default values.

* | | TQM8260: environment in flash instead EEPROM, baudrate 115kWolfgang Denk2008-10-21-22/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several customers have reported problems with the environment in EEPROM, including corrupted content after board reset. Probably the code to prevent I2C Enge Conditions is not working sufficiently. We move the environment to flash now, which allows to have a backup copy plus gives much faster boot times. Also, change the default console initialization to 115200 bps as used on most other boards. Signed-off-by: Wolfgang Denk <wd@denx.de>
