General Purpose Register to Pass Info from Bootloader to OS?

Elijah Lofgren
Prodigy 50 points

I would like to pass information from a Stage One and Stage Two Bootloader to an Operating System.

One idea is to use a general purpose register which I write to in the Stage One and Stage Two bootloaders which the Operating System could later read once it is loaded.

My omap_3530_datasheet.pdf says that the 3530 has it has "64 32-Bit General-Purpose Registers"

I think I may be missing something obvious, but I have searched the datasheet, online, and omap35x_TRM_spruf98d.pdf for General-Purpose Registers that I could use and haven't been able to find a list or names of ones I could use.

Do you have any suggestions?

Thanks,

Elijah Lofgren
