[U-Boot] [PATCH v2 0/3][Net][ARM] Davinci Ethernet driver cleanup

[U-Boot] [PATCH v2 0/3][Net][ARM] Davinci Ethernet driver cleanup

[Ben Warren]

Hello,

The second spin of this patchset is identical to the first but has been
re-based against u-boot/next.  Since there were no technical objections with
the first spin, I've applied this to the net/next branch.

Please let me know if there are any problems.

regards,
Ben

[U-Boot] [PATCH v2 1/3][Net][ARM] Moved Davinci Ethernet driver to drivers/net

[U-Boot] [PATCH v2 0/3][Net][ARM] Davinci Ethernet driver cleanup

[Paulraj, Sandeep]

Ben,
    I believe there was a comment regrading the name of the file.
The present name is dm644x_emac.c and it should be davinci_emac.c
Because other floavours of DaVinci will use the same file.

IIRC in the list had the same comment.
Also the patch uses "dm644x_emac_initialize"
It would be better to use davinci_emac_initialize.

There are not big changes and I can send in a patch if its is 
ok with you.

Thanks,
Sandeep

It's better for me to redo the patch set.  I named them based on 
comments in the header of the source file.
