* Fix calculation of I2C clock for some 86xx chipsTimur Tabi2008-04-30-1/+13
| | | | | | | | | Some 86xx chips use CCB as the base clock for the I2C, and others used CCB/2. There is no pattern that can be used to determine which chips use which frequency, so the only way to determine is to look up the actual SOC designation and use the right value for that SOC.

* 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>
* Update SVR numbers to expand supportAndy Fleming2008-03-26-1/+1
| | | | | | | | | | | | | FSL has taken to using SVR[16:23] as an SOC sub-version field. This is used to distinguish certain variants within an SOC family. To account for this, we add the SVR_SOC_VER() macro, and update the SVR_* constants to reflect the larger value. We also add SVR numbers for all of the current variants. Finally, to make things neater, rather than use an enormous switch statement to print out the CPU type, we create and array of SVR/name pairs (using a macro), and print out the CPU name that matches the SVR SOC version.

* 86xx: Convert sbc8641d to use libfdt.Jon Loeliger2008-02-18-66/+47
| | | | | | | | | | | | | | | This is the proper fix for a missing closing brace in the function ft_cpu_setup() noticed by joe.hamman <at> embeddedspecialties.com. The ft_cpu_setup() function in mpc8641hpcn.c should have been removed earlier as it was under the obsolete CONFIG_OF_FLAT_TREE, but was missed. Only, the sbc8641d was nominally still using it. It all got ripped out, and the funcality that was in ft_board_setup() was refactored to remove the CPU portions into the new file cpu/mpc86xx/fdt.c instead. Make sbc8641d use this now. Based loosely on an original patch from joe.hamman@embeddedspecialties.com Signed-off-by: Jon Loeliger <jdl@freescale.com>

* | PPC: Use r2 instead of r29 as global data pointerWolfgang Denk2008-02-14-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | R29 was an unlucky choice as with recent toolchains (gcc-4.2.x) gcc will refuse to use load/store multiple insns; instead, it issues a list of simple load/store instructions upon function entry and exit, resulting in bigger code size, which in turn makes the build for a few boards fail. Use r2 instead. Signed-off-by: Wolfgang Denk <wd@denx.de>

* 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>

In a subsequent patch, this will be utilized by the 85xx ports as well. Common PCI-E IMMAP register blocks for FSL 85xx/86xx are added. Also enable the second PCI-Express controller on 8641 by getting its BATS and CFG_ setup right. Fixed a u16 vendor compiler warning in AHCI driver too.
