[U-Boot] [PATCH 2/8] armv8: Add workaround for USB erratum A-009798

2017-07-09 Thread Ran Wang
The default setting for USB High Speed Squelch Threshold results in a threshold close to or lower than 100mV. This leads to Receiver Compliance test failure for a 100mV threshold. The changes shift the threshold from ~100mV woards ~130mV resulting in passing of USB High Speed Receiver Sensitivity
