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
v2 -> v3:
- new patch: fdt_support: split fdt_getprop_u32_default
- new patch: fdt_support: Add helper function to read "ranges" property
- new patch: PPC: 85xx: Remove IVOR reset
- removed patch: PPC 85xx: Detect e500v2 / e500mc during runtime
- merge dt patches into machine patch
- Document and rename CONFIG_SYS_USE_DYNAMIC_TLBS
- remove CONFIG_DDR_SPD
- Reduce PCI message to only base address
- Map AS=1 fdt behind CCSRBAR
- Use CONFIG_SYS_CCSR_DO_NOT_RELOCATE
- remove unnecessary ccsr map
- s/cell size/cell count/
- add temporary map define
- use fdt_get_base_address() to find region
- use new APIs
- remove myfdt helpers
v3 -> v4:
- tlb_map_range: return unmapped size
- tlb_map_range: take ram/io parameter as enum rather than bool
- use new tlb map syntax
- check that tlb map mapped everything
- always save/restore r3 for cpu_init_early_f
- remove CONFIG_DYNAMIC_CCSRBAR
- make init_tlbs weak and remove all init_tlbs_dynamic() cruft
- always map fdt to fixed virtual address
- fold together AS=1 fdt map functions
- use tlb_map_range for CCSR map
- search for PCI based on device type rather than compatible
- remove unnecessary cast
- call get_linear_ram_size directly
- override get_tbclk with timebase-frequency fetching code
