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

From: Igor Mammedov
Subject: [PATCH REPOST v3 16/80] arm/kzm: drop RAM size fixup
Date: Thu, 23 Jan 2020 12:37:41 +0100

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

 * reword error message and use size_to_str() to pretty print suggested size
