Subject: [PATCH 33/34] ARM: disable HAVE_CONFIGURABLE_MEMORY_LAYOUT
Date: Sun, 27 Jan 2013 11:47:02 +0100 [thread overview]
Message-ID: <1359283623-1782-34-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1359283623-1782-1-git-send-email-s.hauer@pengutronix.de>
HAVE_CONFIGURABLE_MEMORY_LAYOUT was first meant as a feature, now it's a
feature to remove it. barebox on ARM now completely uses the memory passed
in from the lowlevel code and configures the malloc area and stack space
during runtime making it obsolete to hardcode these values.
