[dpdk-dev] [PATCH v16 0/3] Arm build options rework

The current way of specifying Arm configuration options is insufficient
since we can't identify the SoC we're building for from the MIDR
information. For example, we can't distinguish between N1SDP, Graviton2
or Ampere Altra.
We also want to be able to enable/disable which drivers are built
without user input. This is useful when building:
1. on an SoC that is slow and we want to build only what is necessary
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:
* x86 -> aarch64 cross build with added config options/enabled or
* aarch64 -> aarch64 builds for a different SoCs using meson -Dplatform
option or using a cross file
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.
Juraj Linkeš (3):
build: disable/enable drivers in Arm builds
build: add 'platform' meson option and Arm SoC config
config: fix Arm implementer and its SoCs
