Thanks,

it completely depends on your processor.  but you never said what
processor you're actually using.

u-boot itself has no limitation to prevent booting from spi flash.  or
really any other flash type.

I do boot one custom MX51EVK board from ATMEL SPI NorFlash using
U-BOOT-2010.06.
The SPI flash driver works fine, if not mention SPI controller driver.

This board is not supported in mainline code, so with the existing
code the answer to your question is a clear "no" (lacking all support
for this board), or, after somebody ports U-Boot to that system, a
"maybe" (depending if the CPU supports that boot mode and the
developer decides to support it.

Best regards,

Wolfgang Denk
