Summary: characters is not shown correctly in u-boot jtag console test
Details:
In u-boot jtag console test, run command "echo test", it shows "echo test\n\rtest\n\rbfin>".
For jtag test in kernel, run the same command, it shows "echo test\r\ntest\r\nbfin>". Usually I get "\r\n" at the end of a line in log file, not "\n\r".

Follow-ups

I think both "\n\r" and "\r\n" are valid next line mark in
console. Vivi is better to change the test script to accept both.

OK, test script is updated in branch 2010r1 and trunk.
Close now.
