Subject: [PATCH] ARM: Increase automatic malloc area space
Date: Mon, 21 Jul 2014 15:51:39 +0200 [thread overview]
Message-ID: <1405950699-23106-1-git-send-email-s.hauer@pengutronix.de> (raw)
This increases the malloc to half of the available memory in a
bank. This helps with some usecases requiring a lot of memory.
The other half is still available as scratch area and for
putting the kernel binary.
