why not to add this in kernel DT
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.
Yes, we'll wait until we can get this all in via OF_UPSTREAM.
Tom, Udit,
The patch in Kernel DT here [0] seems to be taking longer to go through. In the meantime, does it make sense for me to send this current series in u-boot with the bootph patch above, to unblock ESM support for j7200-evm?
When the Kernel DT patch is merged and taken through OF_UPSTREAM, I will anyway send a patch to remove all of the bootph from the u-boot DT files. With that, I can take care of removing the above bootph property too.
Let me know what you think, and I'll rebase this series and resend it then.
