Re: [U-Boot] [PATCH V3] AT91: Small fix on AT91 USART initialization code

Dear Hong Xu,

Before reset dbgu transmitter, we just wait TXEMPTY to drain the transmitter register(Just in case). If not doing this, we may sometimes see several weird characters from DBGU.

A short delay is also added to make sure the new serial settings are settled.

Changes since V2, Using __udelay to avoid potential endless loop
