Hi Peter,
Digging up where my u-boot came from, I found:
https://plus.google.com/103895730806848715870/posts/cCq2CxDogW9
Unfortunately, gitorious no longer exists, but I do still have a clone
of that tree locally, containing:
9f384308319e OMAP4SDP: Add Micrel KS8851 net chip support
ae631b095a87 NET: Add driver for Micrel KS8851
78e43f2a8987 ARMV7: OMAP: Add spi driver for OMAP3/OMAP4
e576c6a9cbc9 omap4_common: config: remove I2C for SPL mode
19d5934c4b3b ARM: OMAP4: Move TEXT_BASE down to non-HS limit
plus some of my own modifications to fix the problems stated in that
post.
