EFI BIOS of Imac Pro leaked some time ago

A bit old news, but
With some of DP for high sierra Apple has accidentially released fw for imac pro.
You can find it here – https://github.com/gdbinit/firmware_vault/blob/master/EFI/Unknown%20Models/AAPJ1371_0058_B00.fd

Why I think it’s imac pro ? dsdt has name of model – imac. ALso there is uefi driver for amd radeon vg10.

That matches imac pro.

few other interesting things I’ve found: apple secure boot and microsoft secure boot support. first time spi flash rom is 16 mb (prevuously it waws 8 mb). voice over uefi driver (siri on separate cpu will work even in uefi ?)
