If you think a bit about this, you may find it more difficult than you
expect. Keep in mind that on most systems supported by U-Boot code
like
int *p = (int *)0;
print("*p = %d\n", *p);
is perfectly legal and supposed to work without any problems -
because 0 is a legal address, and it makes perfect senze that commands
like "md" or "cp" can be used to access it. In the result, strcpy(),
strlen(), mem*() and whatever must beable to work on address 0 likeon
any other address, too.
:-P
Best regards,
