The romstage main() entry point on arm64 boards is usually in mainboard
code, but there are a handful of lines that are always needed in there
and not really mainboard specific (or chipset specific). We keep arguing
every once in a while that this isn't ideal, so rather than arguing any
longer let's just fix it. This patch moves the main() function into arch
code with callbacks that the platform can hook into. (This approach can
probably be expanded onto other architectures, so when that happens this
file should move into src/lib.)
Tested on Cheza and Kevin. I think the approach is straight-forward
enough that we can take this without testing every board. (Note that in
a few cases, this delays some platform-specific calls until after
console_init() and exception_init()... since these functions don't
really take that long, especially if there is no serial console
configured, I don't expect this to cause any issues.)

Enable fast or extended DRAM test based on devicetree setting.
The fast DRAM test takes less than a second, while the
extended runs about 1 minute.
Tested on Cavium Soc.

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
