Up to now, there was support only for EXT filesystem. The reason I put this as RFC is because the file "bootcount_ext.c" will no longer represent the implementation for the EXT filesystem, but also for the FAT filesystem. Should it be renamed? If not, wouldn't it be inconsistent? Cheers, Vasilis P.S: Documentation has not been modified yet, I will submit in the v2 (if any).
