[U-Boot] loadb problem. Hangs on START_CHAR

Dear Bo,

This is the funny part of it.

But you don't even get there. You write you get stuck at the
START_CHAR - eventually there is a bug in the serial driver or even
in the hardware, such that it is not really 8 bit clean, or enables
parity or such.  "loads" s just an ASCII text transfer, i. e. it works
fine when you get only 7 data bits through.  "loadb" will really need
an 8 bit clean link.

Me too.
