If we could move the CFE definitions to a shared header, and consolidate the value used by bcm47xxpart.c as well, that would allow us to build the bcm63xxpart.c file with COMPILE_TEST on other architectures. This does not really have functional value, but for maintainers like Miquel, it allows them to quickly test their entire drivers/mtd/ directory. -- Florian ______________________________________________________ Linux MTD discussion mailing list http://lists.infradead.org/mailman/listinfo/linux-mtd/
