The OMAP3 in my phone boots from the micro-SD card. It reads from the blocks that a file would be stored in if it were the first file copied onto a newly formated VFAT partition (it doesn't parse the FAT, it just *knows* what to read).
So yes: processors can boot from all sorts of things.

In fact OMAP3 boots from an internal ROM and can chain-load other boot device.

To avoid this kludge, starting from version 4.3 e-MMC chips feature two 128K boot partitions with a simplified access procedure: simplified for ROMs.
