Add Arm SoC configuration to Arm meson.build and add a meson option to
enable those options for native builds. This is preferable to
specifying a cross file when doing aarch64 -> aarch64 builds, since the
cross file specifies the toolchain as well.

-Supported cross-compilation targets
------------------------------------
-
-If you wish to build for a target which is not among the current cross-files,
-you may use various combinations of implementer/part number::
-
- Supported implementers:
- 'generic': Generic armv8
- '0x41': Arm
- '0x43': Cavium
- '0x50': Ampere Computing
- '0x56': Marvell ARMADA
- 'dpaa': NXP DPAA
-
- Supported part_numbers for generic:
- 'generic': valid for all armv8-a architectures (unoptimized portable
build)
-
- Supported part_numbers for 0x41, 0x56, dpaa:
- '0xd03': cortex-a53
- '0xd04': cortex-a35
- '0xd09': cortex-a73
- '0xd0a': cortex-a75
- '0xd0b': cortex-a76
- '0xd0c': neoverse-n1
-
- Supported part_numbers for 0x43:
- '0xa1': thunderxt88
- '0xa2': thunderxt81
- '0xa3': thunderxt83
- '0xaf': thunderx2t99
- '0xb2': octeontx2
-
- Supported part_numbers for 0x50:
- '0x0': emag
-
-Other cross file options
-------------------------
-
-There are other options you may specify in a cross file to tailor the build::
-
- Supported extra configuration
- max_numa_nodes = n # will set RTE_MAX_NUMA_NODES
- max_lcores = n # will set RTE_MAX_LCORE
-
- disabled_drivers = ['bus/dpaa', 'crypto'] # add disabled drivers
- # valid values are directories (optionally with their subdirs)
- # in the drivers directory
-
- numa = false # set to false to force building for a non-NUMA
system
- # if not set or set to true, the build system will build for a NUMA
- # system only if libnuma is installed
+Building for an aarch64 SoC on an aarch64 build machine
+-------------------------------------------------------
+
+If you wish to build on an aarch64 build machine for a different aarch64 SoC,
+you don't need a separate cross toolchain, just a different set of
+configuration options. To build for an aarch64 SoC, use the -Darm_soc meson
+option::
+
+ meson soc_build -Darm_soc=<target_soc>
+
+Substitute <target_soc> with one of the supported SoCs::
+
+ generic: Generic un-optimized build for all aarch64 machines.
+ armada: Marvell ARMADA
+ bluefield: NVIDIA BlueField
+ dpaa: NXP DPAA
+ emag: Ampere eMAG
+ graviton2: AWS Graviton2

+ octeontx2: Marvell OCTEON TX2
+ stingray: Broadcom Stingray
