[PATCH REPOST v3 16/80] arm/kzm: drop RAM size fixup

Posted by Igor Mammedov 6 years ago

If the user provided too large a RAM size, the code used to
complain and trim it to the max size.  Now tht RAM is allocated by
generic code, that's no longer possible, so generate an error and
exit instead.

 * rephrase commit message in nicer way
   ("Chubb, Peter (Data61, Kensington NSW)" <Peter.Chubb@data61.csiro.au>)
 * reword error message and use size_to_str() to pretty print suggested size

You can add my 'reviewed-by' to this. There's one really minor typo in
the comment (tht->that) that you may wish to fix before the final
commit.

Thanks,
will do it in v4

(considering that there are already fixes to
the current version, I'll rebase and repost)
