[U-Boot] [PATCH] omap3evm: Add board revision function
Hi Vaibhav/Sanjeev,
Please review this which I plan to submit today.
It almost same as submited on lo.
Regards, Ajay
Added function to differentiate between the OMAP3EVM revisions. The chip-id of the ethernet PHY is being used for this purpose.
Rev A to D : 0x01150000 Rev >= E : 0x92200000

Somehow the local patch got sent to the list. Apologies for it.
Please find the correct patch attached.

This must be called after setup_net_chip() else ethernet id Read statement wouldn't work.
I will resubmit this patch.
