Hi Tom,
This is the first batch of ARC changes for the next release.
Here we:
Significantly rework cache-related functionality. In particular that fixes coherency problems in some corner-cases, allows us to enable and disable caches in run-time and still have properly running system, finally support execution from real flash (before we used to run from DDR from the very beginning).
Remove string routines implemented in assembly. That allows us to build and run U-Boot on wide range og ARC cores with different configurations. I.e. whatever tuning is used on GCC's command-line we'll get code for desired flavor of ARC. Otherwise for each and every corner-case we would need to add ifdefs in assembly code to accommodate missing instructions etc.
Get use of GCC's garbage collector which helps to slim-down resulting image quite a bit.
Also now we may disable U-Boot self-relocation for ARC if needed either by platform or for debugging purposes.
FYI, all of the above would be really good to put into a signed tag, next time :)
Sure will do! Do you want me to do it now as well?
I just copy/pasted it into my merge message. Thanks tho.
