[U-Boot] DMA drivers in U-Boot?

[Simon Schwarz]

Hi List,

I am working on integrating DMA into my SPL. As a matter of fact it is 
already working fine.

So, here are my questions:
- Is there an interest in having DMA drivers in U-Boot? (I only know of 
one in /drivers)
- Is there an API I should implement?
- Any other comments?

(ATM the transfer of the Linux-image is more than three times faster 
compared to the CPU copy)

Regards
Simon
