AFAIK, elftosb is only needed for i.MX23x and i.MX28x, which are quite 
newcomers in the i.MX family.
Moreover if your i.MX23/28 systems has a FLASH chip onboard, .sb files 
are only needed to generate an bootable U-Boot image.

+1
Some Freescale guys are also also doing some hard work to mainline i.MX 
drivers.
