After upgrading to OpenWrt 22.03, I've noticed a weird thing. My Linux clients are logging these error messages:
kernel: IPv6: addrconf: prefix option has invalid lifetime
I have a DHCP configuration like shown below. I'm using a life time of 30min for the DHCP leases and the option ra_useleasetime should make the leasetime to be also used as limit and preferred lifetime of the IPv6 prefix.
However, I'm getting invalid preferred lifetimes for the advertised prefixes:

The preferred life time has to be always equal or less than the valid life time and the documented behaviour of ra_useleasetime is not honored, so this looks like a bug.

Make use of the definitions from trusted-firmware-a.mk to build the
Trusted firmware arm. This fixes the build with binutils 2.39.
