I can't confirm your complaints. Here it works (at least on tricorder, which utilizes BCH for U-Boot section in SPL):
Hi Andreas,
Thanks for your response---this was very helpful. When I boot my board using the tricorder board file, it flashes nand correctly. Likewise, I moved over some of the NAND configuration from include/configs/tricorder.h to include/configs/omap3_overo.h and, after a little rearranging to enlarge SPL, it also flashed NAND correctly.
So...any guesses what it is about setting these variables that gets NAND flashing to work properly?
