Hi Thomas,

Patch is reject.

--------^^^^^

The existing code uses stxio instructions, which by their very purpose, bypass the cache. So there's no need to flush the data cache.

One could argue that invalidating the _instruction_ cache may be necessary ... but I doubt it, given that first instructions after reset invalidate the entire instruction cache. It would be a defensive nevertheless.
