Subject: [U-Boot] convention for SPI dummy data?
Date: Fri, 23 Apr 2010 10:43:07 +0200	[thread overview]
Message-ID: <20100423084307.GN20047@leila.ping.de> (raw)

Hi,

I have finally got MMC/SD working on my coldfire board and would like
to send some patches.

However, one of the things I had to change was the dummy data sent
out by SPI for read-only transactions. The original driver had all
zeros, for SD/MMC all ones (0xFF) is needed.

Is such a change acceptable, or is there any configuration option/flag
I could use?

Regards,
Wolfgang
