This is an attempt to tidy up the early SPL code in an attempt to pave the way for driver model in SPL:
- Avoid setting up SDRAM before board_init_f()
- Avoid touching global_data before board_init_f()
- Allow board_init_f() to set up a new stack (seems that the SRAM stack
is not large enough on these boards)
This needs more work but it does boot on Beaglebone Black.

This takes things in the wrong direction I think. Since omap3/4/5 have the same problem we're going to have to duplicate a bunch of this code. But we can do omap_save_boot_params a bit later I'm pretty sure we can shove it into spl_board_init() in arch/arm/cpu/armv7/omap-common/boot-common.c and I'm going to do my best to do that today and test it on at least a few boards.
