[PATCH v2][RFC] Beagle Rev C5 support

[Koen Kooi]

From: Joel Fernandes <agnel...@gmail.com>

This patch adds Rev C5 support for a new memory chip that was added to
the Beagleboard Revision C5. The chip is 256MB SDRAM and the following
patch enables it.

The micron memory chip part is: MT29C4G48MAZAPAKQ-5 IT.

I have tested my patch and it works fine but before I submit it, I
will be grateful if I can get some review feedback (specially with the
details of timing and AC parameter values). Thanks

Changes since v1:
* removed mailer whitespace damage - Koen

I am sorry sir, we won't do your homework

[Jason Kridner]

Can you elaborate more on what you are requesting? What instructions
are you following? What files are you talking about?
