[U-Boot-Users] M-Systems Disk on Chip and U-boot

[Woodruff, Richard]

There are some MDOC drivers in the kernel MTD system at present. Putting
them in u-boot wouldn't be so much of a stretch.

How you use the single part in u-boot will depend on how big xip region
is and its attributes.  You might get away with folding it right in, or
you might need a sub loader like we used for our TI NAND boots for OMAP
processors.

The OMAP 16xx/17xx/24xx processor allow for booting from a RAW NAND
devices and can be made to work with u-boot.  In there case they have
microcode in the cpu which reads some blocks of nand into onchip SRAM
and executes it.

Regards,
Richard W.
