- Subject: [PATCH] feat(fvp): add stdout-path
- Add stdout-path to the fvp-base devicetree to be passed to BL33 (U-Boot)
- and then to the Linux kernel to be compliant to Arm SystemReady IR:
- https://developer.arm.com/documentation/DUI1101/2-0/
- Configure-U-Boot-for-SystemReady/Adapt-the-Devicetree
- This has been tested by booting fvp-base to Linux and ensuring the
- console is accessible.
