There are ARM systems which are essentially heterogeneous multicores where
some cores implement a different ARM architecture version than other cores. A
specific example is the tegra124 which boots on an ARMv4 coprocessor while
most code, including most of the firmware, runs on the main ARMv7 core. To
support SOCs like this, the plan is to generalize the ARM architecture so that
all versions are available, and an SOC/CPU can then select what architecture
variant should be used for each component of the firmware; bootblock,
romstage, and ramstage.

TEST=Built libpayload and coreboot for link, pit and nyan. Booted into the
bootblock on nyan.

It's just good hygiene.

This program lets you test run a snow coreboot image in user mode
on a properly equipped arm system (usually an ARM chromebook).
This is a real time saver as you don't have to flash each time.
We've found and fixed some nasty bugs with this one.
Anyway, the instructions on how to use this are in the binary.
