[U-Boot] [PATCH v2 0/6] PPC 85xx: Add support for QEMU's ppce500 PV machine

[Alexander Graf]

In QEMU we implement a PV machine type called "ppce500". That board is able
to run any e500+ FSL cores (e500v2, e500mc, e5500, e6500).

It is heavily inspired by the MPC8544DS SoC and board combination, but
implements only the bare minimum to make Linux happy enough to drive a
virtual machine.

This patch set implements support for this PV machine type in U-Boot, enabling
users to run their virtual machines with netboot, u-boot payload binaries or
other fun things they come up with.

v1 -> v2:

  - Write device tree offset directly into global variable
  - use r4 rather than r2 for that
  - access fdt directly from in-memory copy
  - remove unneeded header includes
  - clean up pci enumeration
  - coding style fixes
  - populate and only use fdt_addr_r
  - remove unused exported functions
  - remove unused TLB0 entries
  - make TLB1 I/O maps non-executable
  - remove unused defines in board header
  - make -kernel boot variables more clear
  - remove TLB0 invalidation
  - use tlb1.14 for temporary as=1 map
  - use CONFIG_SYS_MPC85XX_NO_RESETVEC
  - store fdt pointer in gd through cpu_init_early_f()
  - replace fixup_tlb1() with dynamic TLB creation hook
  - find CCSRBAR from device tree
  - find PCI controllers from device tree
  - find CPU speed from device tree
