[zhangyu-duck]

Note: Please adhere to Contributing Guidelines.

Summary

Two main updates:

1. Uses the official Infineon ILLD repository instead of a private repository.
2. Adds support for tc4xx series chips and boards

Impact

support tc4xx chip

Testing

1. Both cmake and makefile methods can compile tc3xx/tc4xx.
2. pass ostest, basic functions are normal

@zhangyu-duck please update the Documentation https://nuttx.apache.org/docs/latest/platforms/tricore/index.html to include these new chips.

Unfortunately our Documentation is very non-standardized, some Documentation arch are very good, others are very primitive (let say not helpful). So, I suggest you to use https://nuttx.apache.org/docs/latest/platforms/arm/imxrt/index.html as a good reference.

I guess since this modifies the TC3xx logic as well, could you please include an OSTest log from a tc3 board? The tc4 log looks good.

Also I won't block the PR about this since I have pretty much no familiarity with the tricore architecture, but is it necessary to use the SDK? It seems like this PR needs to include a lot of workarounds for quirks with the SDK (like the libc stubs and patch files). Is it at all possible to avoid using the SDK directly? I know a few other archs in NuttX use this approach (hence why I don't think it's a dealbreaker or anything), but I also know the preferred method is to avoid using vendor SDKs/HALs entirely if possible.

Hi zhangyu-duck,

Great job!

My suggestion is to leave the iLLD unchanged and only configure it using the IFX_XXX macros.

For your reference, I have already ported NuttX to TC4xN based on iLLD in our internal project, and this port does not modify the iLLD itself.

Since infineon have open-source plans, I recommend using the ILD library they provide on GitHub.
and what we change for illd are almost bugs, so i think it may ok

Can you please perform a test on a TV3 device as well since both are modified?
