You're able to have CONFIG_SYS_TEXT_BASE that low and not have the corruption problem devkit8000 had?
No, I can't see any problems. I have to say I can't do _real_ MMC boot, as my board lacks the required jumper, so I'm testing it but starting SPL from NAND, rewriting omap3_boot_device to be MMC with BDI and running it further. It reads u-boot.img from MMC and starts it without any problem.
Well, is it just your board that's missing the jumper, or the MCX HTWK lacks the jumper? If the latter, just drop the MMC bits out :)
I can't ;) this was an explicit requirement.
As for the devkit8000 boot problem, I have BSS set up close to the top of the RAM. Probably that's the reason I don't see any problems.
Unfortunately, I can't recall why I had moved BSS... It clashed with something but I don't remember the details.
Regards, Ilya.
