      85xx: Introduce determine_mp_bootpg() helper. · c840d26c
      Kumar Gala authored
      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.

      mpc8[56]xx: Put localbus clock in device tree · 58ec4866
      Trent Piepho authored
      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.
