Hi all,
First, let me apologize for the mistaken extra changes in r2134.
While I have reverted them in 2135, they do reflect some cleanup and
touch-ups required to support my platform, and I have been meaning to
take some time to figure out how to integrate these properly. Since
this is the second time these changes have unexpectedly visited the
mailing list, I figure now is a good a time as any to discuss them.
Does anyone have the hardware for which this target configuration works
as it is written? Would you like to work with me to factor the STR91x
support in the tree into smaller pieces, such that we do not have to
repeat the chip configuration steps repeatedly throughout the TCL tree?
To wit, I would like to eliminate the duplication between the str912.cfg
file and the str9-comstick.cfg that exists presently. This work should
also document how others can rewrite other configuration files.
Cheers,
Zach
