* qe: fixup the snum for MPC8569 Rev2.0Liu Yu2010-01-25-0/+18
| | | | | | | | Since 1.0 and 2.0 use different snum table, we fixup the snum value according to SPRN_SVR. Signed-off-by: Liu Yu <yu.liu@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* 85xx: Add support to set DPAA (data path) devices clock frequenciesKumar Gala2010-01-05-0/+36

* 85xx: Add support for e500mc cache stashingKumar Gala2010-01-05-0/+18
| | | | | | | | | | | | | | The e500mc core supports the ability to stash into the L1 or L2 cache, however we need to uniquely identify the caches with an id. We use the following equation to set the various stash-ids: 32 + coreID*2 + 0(L1) or 1(L2) The 0 (for L1) or 1 (for L2) matches the CT field used be various cache control instructions.

* 85xx: MP Boot Page Translation updatePeter Tyser2009-10-27-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change has 3 goals: - Have secondary cores be released into spin loops at their 'true' address in SDRAM. Previously, secondary cores were put into spin loops in the 0xfffffxxx address range which required that boot page translation was always enabled while cores were in their spin loops. - Allow the TLB window that the primary core uses to access the secondary cores boot page to be placed at any address. Previously, a TLB window at 0xfffff000 was always used to access the seconary cores' boot page. This TLB address requirement overlapped with other peripherals on some boards (eg XPedite5370). By default, the boot page TLB will still use the 0xfffffxxx address range, but this can be overridden on a board-by-board basis by defining a custom CONFIG_BPTR_VIRT_ADDR. Note that the TLB used to map the boot page remains in use while U-Boot executes. Previously it was only temporarily used, then restored to its initial value. - Allow Boot Page Translation to be disabled on bootup. Previously, Boot Page Translation was always left enabled after secondary cores were brought out of reset. This caused the 0xfffffxxx address range to somewhat "magically" be translated to an address in SDRAM. Some boards may not want this oddity in their memory map, so defining CONFIG_MPC8xxx_DISABLE_BPTR will turn off Boot Page Translation after the secondary cores are initialized. These changes are only applicable to 85xx boards with CONFIG_MP defined. Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* ppc/p4080: Handle timebase enabling and frequency reportingKumar Gala2009-09-24-1/+1
| | | | | | | | | On CoreNet style platforms the timebase frequency is the bus frequency defined by 16 (on PQ3 it is divide by 8). Also on the CoreNet platforms the core not longer controls the enabling of the timebase. We now need to enable the boot core's timebase via CCSR register writes.

* ppc/85xx/86xx: Device tree fixup for number of coresPoonam Aggrwal2009-09-08-0/+2
| | | | | | | | | | | | | | 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>

* 85xx: Always attempt ethernet device tree fixupKumar Gala2009-06-12-3/+0
| | | | | | | | | | | Its reasonable that we may have ethernet devices but dont have drivers or support enabled for them in u-boot and want the device tree fixed up. Unconditionally calling the ethernet fixup is fine since if we dont have ethernet nodes that match (or aliases) we will not attempt to do anything.

* 85xx: Introduce determine_mp_bootpg() helper.Kumar Gala2009-04-01-7/+2
| | | | | | | | | | | | Match determine_mp_bootpg() that was added for 86xx. We 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. Also added a comment about how cpu_reset() is dealing w/an errata on early 85xx MP HW. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* mpc8[56]xx: Put localbus clock in device treeTrent Piepho2008-12-19-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* 8xxx-fdt: set ns16550 clock from CFG_NS16550_CLK, not bi_busfreqPaul Gortmaker2008-07-14-1/+1
| | | | | | | | | | 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.
