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.
