arm/arm64: dts: Use ip=on for bootargs
[PATCH 1/2] arm: dts: Use ip=on for bootargs
[PATCH 2/2] arm64: dts: renesas: Use ip=on for bootargs
These patches convert boards from Renesas that use ip=dhcp in bootargs to
ip=on to allow more flexible network protocol auto configuration support.
The supported network protocols used for auto configuration depend both
on the ip= boot argument and the kernel configuration.
The arm64 defconfig currently contains the following Kconfig symbols:
CONFIG_IP_PNP=y
CONFIG_IP_PNP_DHCP=y
CONFIG_IP_PNP_BOOTP=y
# CONFIG_IP_PNP_RARP is not set
Unless overridden by the user the above kernel configuration with ip=on
results in that the kernel will perform auto configuration with both BOOTP
and DHCP during boot. Compared to DHCP the user will not experience any
real difference unless he/she also has a BOOTP server on the same network
and relies on ip=dhcp to pick the desired protocol.
I recall the ISC DHCP server being a helpful tool to test BOOTP and DHCP.
