Zhiqiang,

This patch has been merged but I found an issue with it today. Please 
try to boot P4080DS from NOR flash. It causes recursive calls
fsl_serdes_init()->p4080_erratum_serdes_a005()->is_serdes_configured()->fsl_serdes_init(). 
Please check if you have any similar recursive case for other platforms. 
Please send a fix ASAP.
