Check if additional memory is required for MMC upgrade

Memory needs to hold both current and updated firmware at the same time so that new firmware can be verified.

Hi, Krzyzstof. You mean if we need more memory for openMMC or if we would need more memory to make firmware updates safer?

@gustavo.bruno Exactly. Sorry for poor description.

changed the description

LPC1764 on AFC v3.1 has 128 kB flash memory, LPC1768 has 512 kB flash memory and openMMC binary is up to 100 kB currently. 512 kB should be enough to make updates for some time but it all depends on openMMC development.

To be honest I don't expect such rapid development of openMMC in the foreseeable future. Let's not complicate schematics if it's not absolutely necessary.

@msowinski, for better documentation: could you rephrase "check if additional memory is required for MMC upgrade" to "Check if additional external memory is required for MMC upgrade"?

Just not to mistaken "additional memory" with "additional LPC internal memory capacity".
