* 86xx: remove the redundant r2 global data pointer saveDave Liu2008-10-30-1/+0
| | | | | | | | | | The commit 67256678f00c09b0a7f19e862e5c1847553d31bc add the another global data pointer save, but in fact the global data pointer will be initialized in the board_init_r, so remove it such as the 85xx/83xx family.

* | 85xx: Fix the incorrect register used for DDR erratum1Dave Liu2008-10-24-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Dave Liu <daveliu@freescale.com>

* 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.
