So the (let me call it) "internal MLO" is not stored on NAND-flash as
mentioned before but on a FAT-partition of eMMC?

Assumed my internal MLO got lost for some reason and I only can boot
some own (bare-metal) applications from external SD-card, is there a
way to access or restore that internal FAT-partition without using a
full Linux-installation on my SD card? A OpenOCD JTAG debugger would
be available...

Thanks!
