Getting this error:
Zynq> sb load hostfs - 100
/home/monstr/data/disk/u-boot/build-zynq_zc706/test.fit
Unknown command 'sb' - try 'help'

because sb command is present only for Sandbox
obj-$(CONFIG_SANDBOX) += host.o

that's why mark this test to be run only at Sandbox

Without this, the test fails if the test is run with a cwd other than the
root of the U-Boot source tree.

Now that we have a suitable test framework we should move all tests into it.
The vboot test is a suitable candidate. Rewrite it in Python and move the
data files into an appropriate directory.
