This patch set adds support for building images for SoC that make usage
of Armv8 application CPUs and Cortex-M/Cortex-R service CPUs.
The application CPU cross-toolchain is unable to generate 32-bit THUMB
code, therefore usage of secondary toolchain is needed.
The required pre-built toolchain is taken from ARM developers site and
installed in host filesystem only.
The patch set makes use of dual toolchain for adding support for Marvell
Armada 3700 SoC that uses both Cortex-A53 and Cortex-M3 CPUs for running
system firmware.

From: Konstantin Porotchkin <kostap@marvell.com>

Add host-only 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-build bate metal ARM GNU-RM toolchain
into the host file system folder /opt/gcc-arm for covering the
above mentioned cases.

Hello,

Title should be:

	package/arm-gnu-rm-toolchain: new package

"host-only" doesn't mean much here. It's a cross-compilation toolchain,
so it's not really "host-only".

> This patch installs pre-build bate metal ARM GNU-RM toolchain

pre-build -> "a pre-built"

> into the host file system folder /opt/gcc-arm for covering the
> above mentioned cases.

"into the host filesystem folder /opt/gcc-arm" ->
$(HOST_DIR)/opt/gcc-arm

I don't think we need a Config.in.host option for this.

These two lines together don't make sense. If you select
BR2_HOSTARCH_NEEDS_IA32_LIBS, it's because the pre-built binaries are
for x86 32 bits, and therefore the 32 bit compat libraries are needed
when running on a x86-64 system. If pre-built binaries are for x86 32
bits, then surely the dependency on BR2_HOSTARCH = "x86_64" is not
correct.

But anyway as stated above, I don't think a Config.in.host file is
needed here.

Why do you need custom extract commands ? It seems to be just a regular
tarball.

Install in gcc-arm-none-eabi so that it's clear it's a bare-metal
toolchain.

Thanks,

Marvell Armada 37xx firmware code and utilities are kept in
a separate repository. This code is needed as a dependency
to build ATF firmware for Marvell Armada 37xx SoCs.
