Yes, it's a 32-bit T210 U-Boot. T210 supports both AARCH32 and AARCH64. A 64-bit build will follow, but I haven't figured out how to meld the 32-bit AVP SPL portion/build with the 64-bit CPU portion/build in one clean build command, so I'm building them separately and then fusing them together in a separate script. If anyone has ideas on how to generate a hybrid 32-bit (AVP)/64-bit (A57) U-Boot binary in one fell swoop, I'm all ears. :)

We need a 64-bit port. ----------------------------------------------------------------------------------- This email message is for the sole use of the intended recipient(s) and may contain confidential information.
