Some travis QEMU tests can transfer files between the build directory
and the guest U-Boot instance. For that to work, both need to have access
to the same directory.

This patch puts the current build path into an environment variable, so
that the environment generating python scripts can extract it from there
and read the respective files.

The network test currently downloads files at 0MB offset of RAM start.
This works for most ARM systems, but x86 has weird memory layout constraints
on the first MB of RAM.

To not get caught into any of these, let's add a 4MB pad from start
of RAM to the default memory offset.

It makes not sense using u8 to hold a value on a 32-bit or 64-bit machine.
It can only bloat the code by forcing the compiler to mask the value.

Update board_init() to increase the ARM clock to the maximum speed on

At present we have a single rk3288-based Chromebook: chromebook_jerry. But
all such Chromebooks can use the same binary with only device-tree

Also update the device-tree filename since this currently differs from

The current code assumes that the devices are ordered corresponding to
their alias value. But (for example) video1 can come before video0 in the
device tree.

Correct this, by always looking for device 0 first. After that we can fall
