Manorit has already posted a series to kernel to add bootph- properties 
across platforms... Specifically the patch here [0] addresses this.

Once that is merged, and goes through the rebasing tree in u-boot we 
will need to send patches to remove the bootph properties from the 
-u-boot and -r5 files. Until then we need this patch for the ESM to 
work. Else we can wait till the kernel dt patches make it through to 
u-boot for me to roll out a v2.
