[meta-xilinx] [meta-xilinx-bsp][PATCH 0/4] Add SOC_VARIANT as override

[Manjukumar Matha]

UltraScale+ FPGA has different variants of silicon to support different
features like MALI400, VCU. Categorically there are three variants: cg
devices, eg devices(MALI 400) and ev devices (MALI 400+ VCU)

See detailed description of products here:
https://www.xilinx.com/products/silicon-devices/soc/zynq-ultrascale-mpsoc.html#productTable

dr devices are based for UltraScale+ RFSoC

This patch allows machineoverides to be extended as zynqmp(cg|eg|ev|dr)
and mali400/vcu (based on functionality). 

This will extend MACHINEOVERRIDES for each device variant as:
cg --> zynqmpcg
eg --> zynqmpeg
ev --> zynqmpev

and adds mali400:vcu as MACHINEOVERRIDES based on SoC feature.

Similarly for Zynq 7000 devices there are two variants
https://www.xilinx.com/products/silicon-devices/soc/zynq-7000.html#productTable

Available SOC_VARIANT's for zynq:
"7zs" - Zynq-7000 Single A9 Core
"7z"  - Zynq-7000 Dual A9 Core

This will extend MACHINEOVERRIDES for each device variant as:
7zs --> zynq7zs
7z  --> zynq7z

This helps in grouping of settings for similar SoC.
One best example is to pin providers to MALI400 binaries.  If the mali400 is
present in the override then default provider will be libmali-xlnx.  mali400
will be a override only for SOC_VARIANT which are eg and ev devices.

PREFERRED_PROVIDER_virtual/libgles1_mali400    = "libmali-xlnx"
PREFERRED_PROVIDER_virtual/libgles2_mali400    = "libmali-xlnx"
PREFERRED_PROVIDER_virtual/egl_mali400         = "libmali-xlnx"

This patch also adds packages to be a part of the feed based on
SOC_FAMILY and SOC_VARIANT

The use case is to share the sstate-cache or feeds for packages which are
zynqmp based. Some packages can be SoC family based instead of machine.
