Subject: CMA on arm from zero address
Date: Wed, 08 Feb 2012 13:27:58 +0100 [thread overview]
Message-ID: <4F326A4E.1030106@monstr.eu> (raw)
Hi,
I would like to setup CMA space at the beginning of ram because
I want to use remoteproc to run code on the second cpu which has to use addresses 0x0 - 32MB.
I have changed textofs in arch/arm/Makefile but there is not possible to setup
all values which I would like to use. What is the reason for this limitation?
Marek: Have you tried to prototype this configuration with cma?
Thanks,
Michal
