While the initdram() function makes sense on some arches, it doesn't for Blackfin systems as it's always implemented the same way.
Would it not make sense to start using get_ram_size(), too?
i havent heard of this function before. looking through the tree, it seems like this is an optional board-specific function that probes external memory sizes by reading/writing to it.
on a Blackfin system, this is a pretty big waste. memory must always be mapped starting at address 0 which means once the highest address is validated, things can return. ignoring that, the Blackfin port has no relocation support, so the link time addresses are fixed. -mike
