Subject: am33xx: Avoid hard failure on USB probe issue
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=44d86f9194acbd1c649278d7e63b79280f26e1de;p=thirdparty%2Fu-boot.git

am33xx: Avoid hard failure on USB probe issue

Currently if USB fails to probe, U-Boot does not reach the console.

This patch does not fail if USB fails to probe making it easier to debug
in case of issues.
