This fixture name is quite long and results in lots of verbose code. We know this is U-Boot so the 'u_boot_' part is not necessary. But it is also a bit of a misnomer, since it provides access to all the information available to tests. It is not just the console. It would be too confusing to use con as it would be confused with config and it is probably too short. So shorten it to 'ubman'.

iterations and timeout. This test will be automatically skipped without this.

For example:

# Setup env__memtest to set the start address of the memory range, size of the
|
|
# memory range to test from starting address, pattern to be written to memory,
|
|
# number of test iterations, and expected time to complete the test of mtest
|
|
# command. start address, size, and pattern parameters value should be in hex
|
|
# and rest of the params value should be integer.
