[U-Boot] [PATCH v2] test/py: Support setting up specific timeout

Michal Simek
2016-05-18T17:00:56Z

Large file transfers, flash erasing and more complicated tests
requires more time to finish. Provide a way to setup specific
timeout directly in test.

For example description for 50s test:
timeout = 50000
with u_boot_console.temporary_timeout(timeout):
u_boot_console.run_command(...)

Changes in v2:
- save console.p instead of simple console
- Some fixes in comments
- Save orig_timeout directly in class
- Remove get_spawn call
- Test if self.p exists
