[PATCH v3 1/2] arm64: dts: ti: k3-am68-sk/k3-j721s2-mcu: Add bootph-all property to enable Ethernet boot
Posted by Chintan Vankar 9 months, 2 weeks ago 
Ethernet boot requires CPSW nodes to be present starting from R5 SPL
stage. Add bootph-all property to required nodes to enable Ethernet boot
on AM68-SK and J721S2-EVM.

Link to v2:
https://lore.kernel.org/r/20250302153502.181832-2-c-vankar@ti.com/

Changes from v2 to v3:
- Removed "bootph-all" property from "mcu_cpsw" node as suggested by
  Vignesh since child node already has that.

Why does every board that uses j721s2 need to have bootph-all for
cpsw? Is network boot mandatory boot mode for all boards? That does
not sound right. Just do them in the board file please.
