DM6446:How to reserve RAM specific Area
Hello everyone we have made our own custom board i want to reserve a fixed RAM area to be used by other processor One way to do that is to boot the kernel with mem= value and then use the remaining space of the RAM by allocating it using the modules.But in this fashion we will always load the module at the end. I want to know is there any other way to reserve the RAM area anywhere we want.

You may want to do a search. IIRC, the posting is about reserving the 2nd half of the RAM.

Can you please tell which mailing list you are talking about Regard's RT Check out this link. http://www.spinics.net/lists/arm-kernel/msg73544.html Probably need to modify the attached patch for DaVinci.
