This patch rewrites the mtmips architecture with the following changes:
- Move MT7628 soc parts into a subfolder.
- Lock parts of D-Cache as temporary stack.
- Reimplement DDR initialization in C language.
- Reimplement DDR calibration in a clear logic.
- Add full support for auto size detection for DDR1 and DDR2.
- Use accurate CPU clock depending on the input xtal frequency for timer and delay functions.
Note:
print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.
