* 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>

| | | | | | | | | | | | | | | | | | | | | | | | * split the BAT initialization so that only 2 BATs (for the boot page and stack) are programmed very early on. The rest are initialized later. * Move other BAT setup, ccsrbar setup, and law setup later in the code after translation has been enabled. These changes will facilitate the moving of law and BAT initialization to C code, and will aid with 36-bit physical addressing support. Signed-off-by: Becky Bruce <becky.bruce@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>

* Make MPC8641's PCI/PCI-E driver a common driver for many FSL parts.Ed Swarthout2007-08-06-346/+2
| | | | | | | | | | | | | | | | | | All of the PCI/PCI-Express driver and initialization code that was in the MPC8641HPCN port has now been moved into the common drivers/fsl_pci_init.c. 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.

Write a "pixis_reset" command that utilizes the FPGA reset sequencer to support alternate soft-reset options such as using the "alternate" flash bank, enabling the watch dog, or choosing different CPU frequencies.
