Hi Juraj,

> without the user having to check which libraries they have installed
>2. a cross build on a fast aarch64 machine but with target SoC which
> differs in capabilities or libraries.
>This is achieved by specifying the drivers in SoC configuration.

>The current implementation adds/supports the following:

>* aarch64 -> aarch64 builds for a different SoCs using meson -Dplatform

I am unable to apply this series on main branch. I guess it has to be rebased
again?

app/flow-perf: fix encap/decap actions
>v16:
>Only three commits remaining - updated the cover letter.
>Renamed the 'soc' meson option to 'platform'.
>Added the support for enabling a particular set of drivers.
>Aligned enabling and disabling with the command line option so that
>wildcards can be used.

>v17:
>Removed unnecessary comments in "build: disable/enable drivers in
>Arm
>builds". Also always enabled two drivers which break the build if
>disabled.
>
>v18:
>Rebased.
>
>v19:
>Updated 3/3 with more up to date MAX_LCORE and
>MAX_NUMA_NODES for
>neoverse-n1.
