I really like this new trend in Free Software development :-(

The interesting public mailing lists (linuxppc) get shut down, and
discussions about future kernel developments take place on IRC or
"private email exchanges" only.

If you don't happen do be chosen for such elitist circles you cannot
participate in kernel development any more.

This is not my idea of how things should be done.

I will not comment on things I have no chance to get an opinion about.

There is no kernel interface for such stuff in existing Linux kernels
(at least as far as they are accessable by mere mortals). There is
not even a definition of "non-overwrittable area".

As long as there is no agreement how the Linux kernel will handle
these issues (and with "Linux kernel" I mean what you get at
kernel.org, and what works at least on ARM, MIPS and PowerPC) I do
not want to add this to U-Boot.

Best regards,
