> From: Konstantin Porotchkin <kostap at marvell.com>
>
> Add cross-compialtion ARM RM toolchain for supporting firmware
> builds for Armv8-based SoCs utilizing Cortex-M/Cortex-R
> service CPUs.
> The cross-toolchain used for building Armv8 application CPU
> code cannot be used for Cortex-M/Cortex-R 32-bit THUMB code
> generation.
> This patch installs pre-built bate metal ARM GNU-RM toolchain
> into the host file system folder $(HOST_DIR)/opt/gcc-arm-none-eabi
> for covering the above mentioned cases.

You also need to provide the liense, and the URL to the source
tarball(s), like:
ARM_GNU_RM_TOOLCHAIN_LICENSE = so-and-so
ARM_GNU_RM_TOOLCHAIN_LICENSE_FILES = some/file some/other/file
ARM_GNU_RM_TOOLCHAIN_ACTUAL_SOURCE_TARBALL = http://URL/of/source.tar
Note that you will need to also add a hash for the actual source tarball
as well.

You should rather use a mv to avoid the size duplication, like we do in
the external-toolchain infra for the main toolchain.
Also, why do you not install them in $(HOST_DIR)? As it is as you did,
other packages have to know about this specific location, which is not
entirely nice... However, if installing in $(HOST_DIR), maybe we have to
be carefull about not causing name-clashing with other host stuff...
