Hello I have a board that has 4Gb of RAM which can completely be used by Linux, except for a 64Mb block located just below the 2G boundary. This block will be used to implement a kind of persistent storage. On PPC we do this with a memreserve in the device tree but this does not seem to work on MIPS. Another option I found is the memmap kernel parameter, which can also be used the reserve a piece of memory that is reserved (something like memmap=size$addres would do the trick, but no luck, this is also not supported. This is the Linux version I'm using for my project: Linux version 2.6.32.27-Cavium-Octeon What is the correct way to make this work? Thanks, Ronny
