all you need to do is write a flasher and a small "bootloader" which
knows about usb. ROM code can receive data via USB and jump to that
data's entry point.

It's all in the TRM.

that's because OMAP4 doesn't have a PCI controller.

you're on your own, sorry. You need to ask for support from whoever gave
