X-Git-Tag: v2010.03-rc1~95^2~9
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=27165b5c328464b706601b1cd586e359a3dc2f6d;p=platform%2Fkernel%2Fu-boot.git

tsec: Clean up Broadcom PHY status parsing

- Remove unnecessary printing "Enet starting in <speed>/<duplex>"
    This same information is already printed during normal ethernet
    operation in the form "Speed: 1000, full duplex".

- Add a check for link before determining link speed and duplex
    If there is no link, speed/duplex don't matter.  This also removes
    the annoying and unneeded "Auto-neg error, defaulting to 10BT/HD"
    message that occurs when no link is detected.

- Whitespace and line > 80 characters cleanup
