[PATCH v2 1/3] configs: am62ax_evm_r5_ethboot: Enable config options required for Ethernet boot

[Chintan Vankar]

The R5 SPL SRAM size is limited and cannot accommodate both MMC boot and
Ethernet boot config options simultaneously. Add a dedicated defconfig
that enables the Ethernet boot on SK-AM62A-LP for R5 SPL stage.

We already enable SPL_BOARD_INIT for the r5 and a53 defconfigs, rest looks good
to me.

We should have this as part of 'k3-am62a7-r5.dtsi' so that other boards can
also get OOB ethernet boot by just modifying their defconfig.

You can set the boot phase tag in the Linux/upstream device tree. This is also what is done for other nodes required for booting.

I agree with you, I have enabled boot phase tag in a similar manner,
I added the "bootph-all" property along with the "ti,sci" property
there was no specific reason to add "bootph-all" property. I will go
with your approach.

Chintan.

I forgot to mention in my last reply but with ethernet boot added, it
would be helpful to document it in the respective board RST as well.

Thanks for testing the feature, I will add the documentation in next
