Beagle SPI driver update

[Niteesh G. S.]

Hello,

First of all really sorry for the long delay, I am preparing for a robotics
competition
and it eats up most of my free time.

I finally got a logic analyzer and tested the SPI driver using it. And as
expected the
waveforms weren't right. To understand the device better and also to narrow
down
the problem I decided to write a simple polled driver. This driver can be
found
here
https://github.com/gs-niteesh/rtems/blob/8a75a2f5eb6b4eb852da9563b53b6c021463a8c7/bsps/arm/beagle/spi/simple-spi.c

Commit:

This way I was able to get my first byte pushed but the succeeding bytes
time out. I
added the time out to make sure the pushed data is transferred before
getting overwritten
by the succeeding bytes. I also checked other drivers to make sure adding a
timeout is
necessary.
On removing the timeout I was able to get all my bytes pushed successfully.
This was verified using the logic analyzer. But on using the timeout I face
the mentioned
problem. I even tried decreasing the time but still, I face the same issue.
What could be causing the problem? Is there any other way to debug this?

Thanks,
Niteesh.
