It depends on what you mean by fully. If there is a so-called Mask ROM (i.e. initial boot program that's part of the chip itself, not replaceable, you can disassemble it however) and the rest of the chip is fully open, does that count?
For my money the ARM chromebooks are still one of the best bets out there for messing about with ARM firmware.
