What OpenBMC commit are you building from?  It looks like evb-ast2500
got updated to the newer u-boot branch in February:
https://github.com/openbmc/openbmc/commit/7d75b9b68370374db00e9c99b5406ebb6b18512f

If the same image is showing the expected u-boot version in a simulator
(qemu?), then it sounds like maybe your installation procedure isn't
doing what you intended it to.  I don't know what the 'socflash.sh' you
referred to above is; if you can boot into a reasonably healthy OpenBMC
environment, I'd suggest using the normal firmware-update mechanism.  If
the existing firmware is something else or isn't working enough to boot
normally you might need to resort to a hardware flash programmer or
something (or if you can get your u-boot networking working at all, even
at a slow speed, you could TFTP in an OpenBMC kernel/initrd, boot into
that, and use flashcp to write the full OpenBMC image).
