[U-Boot] u-boot with no external RAM, is it possible

[Michael Nickelson]

Is it possible to run u-boot with no external RAM chip?
I have a board using an STM32F437 that does not have memory beyond the
flash and ram present on the chip.
I'm starting with the STM32f429-Discovery build and trying to strip out FMC
and DRAM init sections of code, but not having much luck getting u-boot to
run afterwords.

Thanks in advance,
Mike
