The additional subtargets cause us extra maintenance efforts and we also
need more compute resources for our build bots because we have to build
more. We would like to reduce the number of subtargets especially for
not so much used targets.

Yes, this is one disadvantage, because the sama5d3 does not support the
ARM NEON extension. I do not think this extension brings so much
advantages in the common use cases of OpenWrt and the at91 target is
also not used so much as far as I know.
> 2. We can configure kernel specific to these subtarget.
The kernel configurations of the different sama5 subtargets only had
very little differences. In addition to the specific CONFIG_SOC_SAMA5DX
configuration the sama5d2 subtarget had CAN support and
CONFIG_POSIX_MQUEUE activated, otherwise they used the same kernel
configuration.

The vfpv4 feature flag is still set for the sama5 subtargets, the legacy
subtarget still exists because this is rally a very different CPU.
