[U-Boot] [PATCH] powerpc/85xx: Add workaround for errata USB-14 (enable on P204x/P3041/P50x0)

2013-03-03 Thread xulei
On P204x/P304x/P50x0 Rev1.0, USB transmit will result in false internal multi-bit ECC errors, which has impact on performance, so software should disable all ECC reporting from USB1 and USB2 by setting bits 16 and 17 to 1 in the register at DCSRBASE + 0x0002_0520. In formal release document, the e
