Why? I dunno.

Idea: Limited number of IPATCH locations can be extended via updating the current IPATCH set as each IPATCH is triggered.

i have your n7 branch as a submodule in my repo (thanks btw).

https://github.com/tofurky/tegra30_debrick/blob/master/payload/uart_payload.c does patch out the sig checks. the offset seems to work on both ouya and n7.

edit: sorry, not sig checks. it patches out the IROM fuse checks. one of the patched bootloaders (ouya) actually disables the 'fastboot flash bootloader' sig check.
