2009-09-08ppc/85xx/86xx: Device tree fixup for number of coresPoonam Aggrwal
Fixing the number of cores in the device tree based on the actual number of cores on the system. With this same device tree image can be used for dual core and single core members of otherwise exactly same SOC. For example: * P2020RDB and P2010RDB * P1020RDB and P1011RDB * MPC8641D and MPC8641 Signed-off-by: Poonam Aggrwal <poonam.aggrwal@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-04-0186xx: Cleanup MP supportKumar Gala
* Use CONFIG_MP instead of CONFIG_NUM_CPUS to match 85xx * Introduce determine_mp_bootpg() helper. We'll need this to address a bug introduced in v2009.03 with 86xx MP booting. We have to make sure to reserve the region of memory used for the MP bootpg() so other u-boot code doesn't use it. * Added dummy versions of cpu_reset(), cpu_status() & cpu_release() to allow cmd_mp.c to build and work. In the future we should look at implementing all these functions. This could be common w/85xx if we use spin tables on 86xx. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2008-12-19mpc8[56]xx: Put localbus clock in device treeTrent Piepho
Export the localbus frequency in the device tree, the same way the CPU, TB, CCB, and various other frequencies are exported in their respective device tree nodes. Some localbus devices need this information to be programed correctly, so it makes sense to export it along with the other frequencies. Unfortunately, when someone wrote the localbus dts bindings, they didn't bother to define what the "compatible" property should be. So it seems no one was quite sure what to put in their dts files. Based on current existing dts files in the kernel source, I've used "fsl,pq3-localbus" and "fsl,elbc" for MPC85xx, which are used by almost all of the 85xx devices, and are looked for by the Linux code. The eLBC is apparently not entirely backward compatible with the pq3 LBC and so eLBC equipped platforms like 8572 won't use pq3-localbus. For MPC86xx, I've used "fsl,elbc" which is used by some of the 86xx systems and is also looked for by the Linux code. On MPC8641, I've also used "fsl,mpc8641-localbus" as it is also commonly used in dts files, some of which don't use "fsl,elbc" or any other acceptable name to match on.

2008-11-04powerpc: change 86xx SMP boot methodBecky Bruce
We put the bootpg for the secondary cpus into memory and use BPTR to get to it. This is a step towards converting to the ePAPR boot methodology. Also, the code is written to deal properly with more than 4GB of RAM. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>

2008-08-21fdt: rework fdt_fixup_ethernet() to use env instead of bd_tKumar Gala
Move to using the environment variables 'ethaddr', 'eth1addr', etc.. instead of bd->bi_enetaddr, bi_enet1addr, etc. This makes the code a bit more flexible to the number of ethernet interfaces. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2008-07-148xxx-fdt: set ns16550 clock from CFG_NS16550_CLK, not bi_busfreqPaul Gortmaker
Some boards that have external 16550 UARTs don't have a direct tie between bi_busfreq and the clock used for the UARTs. Boards that do have such a tie should set CFG_NS16550_CLK to be get_bus_freq(0) -- which most of them do already.

2008-02-1886xx: Convert sbc8641d to use libfdt.Jon Loeliger
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.
