RK3288 Hardware Design Guide
Fig 21-2
As shown in Fig 21-3, the value of 25MHz crystal load capacitors（C251,C252）should be
base on nominal loading capacity of the adopted crystal, 12pF matches the crystal we have
chosen, it is not the common value.

L9 inductor in Fig 21-4 should meet the following conditions: IDC>=600mA；
Tolerance<=20%；DCR<=0.8ohms@1MHz；Measure Efficiency>=75%@GbE link speed；
