cavium: Add CN81xx SoC and eval board support
This adds Cavium CN81xx SoC and SFF EVB files.
Code is based off of Cavium's Octeon-TX SDK:
https://github.com/Cavium-Open-Source-Distributions/OCTEON-TX-SDK
BDK coreboot differences:
bootblock:
- Get rid of BDK header
- Add Kconfig for link address
- Move CAR setup code into assembly
- Move unaligned memory access enable into assembly
- Implement custom bootblock entry function
- Add CLIB and CSIB blobs
romstage:
- Use minimal DRAM init only
devicetree:
- Convert FTD to static C file containing key value pairs
Tested on CN81xx:
- Boots to payload
- Tested with GNU/Linux 4.16.3
- All hardware is usable (after applying additional commits)
Implemented in future commits:
- Vboot integration
- MMU suuport
- L2 Cache handling
- ATF from external repo
- Devicetree patching
- Extended DRAM testing
- UART init
Not working:
- Booting a payload
- Booting upstream ATF
TODO:
- Configuration straps
