* 85xx/86xx: Move to dynamic mgmt of LAWsKumar Gala2008-06-11-3/+3
| | | | | | | | | | | With the new LAW interface (set_next_law) we can move to letting the system allocate which LAWs are used for what purpose. This makes life a bit easier going forward with the new DDR code.

* Big white-space cleanup.Wolfgang Denk2008-05-21-1/+1
| | | | | | | | | | | This commit gets rid of a huge amount of silly white-space issues. Especially, all sequences of SPACEs followed by TAB characters get removed (unless they appear in print statements). Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de>
* 85xx/86xx: Rename ext_refrec to timing_cfg_3 to match docsKumar Gala2008-04-29-2/+2
| | | | | | | All the 85xx and 86xx UM describe the register as timing_cfg_3 not as ext_refrec. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* mpc86xx: Fix unused variable 'config' and 'immap'Jean-Christophe PLAGNIOL-VILLARD2008-02-18-4/+6

* 86xx: Remove old-style law setup codeBecky Bruce2008-01-24-27/+0
| | | | | | This includes mpc8610hpcd, mpc8641hpcn, and sbc8641d. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
* 86xx: Support new law setup method and convert mpc8641Becky Bruce2008-01-24-1/+15
| | | | | | | | Adds the support code in cpu/mpc86xx for the new law setup code recently created fsl_law.c, and changes the MPC8641HPCN config to use this code. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
* 86xx: Support 2GB DIMMsBecky Bruce2008-01-10-1/+10
| | | | | | | | Configure the number of bits used to address the banks inside the SDRAM device. The default register value of 0 means 2 bits to address 4 banks. Higher capacity devices like a 2GB DIMM require 3 bits to address 8 banks. Signed-off-by: Becky Bruce <bgill@freescale.com>

* 86xx: Fix broken variable reference when #def DEBUGing.Jon Loeliger2007-11-17-2/+4
| | | | | | Sometimes you can't reference the DDR2 controller variables. Signed-off-by: Jon Loeliger <jdl@freescale.com>
* 86xx: Allow for fewer DDR slots per memory controller.Jon Loeliger2007-10-16-9/+21
| | | | | | | | | | | | | As a direct correlation exists between DDR DIMM slots and SPD EEPROM addresses used to configure them, use the individually defined SPD_EEPROM_ADDRESS* values to determine if a DDR DIMM slot should have its SPD configuration read or not. Effectively, this now allows for 1 or 2 DIMM slots per memory controller. Signed-off-by: Jon Loeliger <jdl@freescale.com>
* Rewrote picos_to_clk() to avoid rounding errors.James Yang2007-05-01-8/+20
| | | | | | | | Clarified that conversion is to DRAM clocks rather than platform clocks. Made function static to spd_sdram.c. Signed-off-by: James Yang <James.Yang@freescale.com> Signed-off-by: Jon Loeliger <jdl@freescale.com>
* Add support for 8641 Rev 2 silicon.Ed Swarthout2007-03-22-2/+2
