If I understand correctly
Boot rom dont care about the FAT table . its only read first several
blocks
generally , MLO should be on the 2nd block ,1st block is MBR ,
But if there is a FAT file system . 2nd block should be fat table ,
What I remember is
omap3 have 64k SRAM , omap4 have 32k SRAM ,dm8148/j4/j5 have SRAM ,dm8168
have 256k
am335x have 64k SRAM

whats my failed boot experience is when
the files are in the 1Mb hole in the front of the SD card, dd it is not
touching the bootrom (if I understand your question )

Bootrom is inside the am335x... It's rom, so we can't modify it..
