[Buildroot] [PATCH 1/3] arch/csky: Add ck860 and vdsp compiler options

[guoren at kernel.org]

From: Guo Ren <ren_guo@c-sky.com>

The ck860 is C-SKY abiv2 cpu series and it could support SMP and vdsp
instructions set. Add the compiler options for them.

[Buildroot] [PATCH 2/3] arch: Add support for C-SKY toolchain build

[guoren at kernel.org]

From: Guo Ren <ren_guo@c-sky.com>

This enables csky to be built with generated toolchain:
 - gcc 6.3
 - binutils 2.27
 - gdb 7.12
 - glibc 2.28

All of them has been tested with csky gitlab-ci based on buildroot:
 - https://gitlab.com/c-sky/buildroot/pipelines

 This should be split into separate patches:

- binutils
- gcc
- glibc
- toolchain-buildroot
- gdb

 You also have to update Config.in.host to get rid of the version selection there.

 However, I do agree that the pattern you use here is nicer. So I think in
Config.in.host, you should have:

if !BR2_arc && !BR2_csky
choice
        prompt "Binutils Version"
	default BR2_BINUTILS_VERSION_2_31_X
... (without arc option)
endif

config BR2_BINUTILS_ENABLE_LTO


 And in the .mk file, put the condition on the arch outside:

ifeq ($(BR2_arc),y)
BINUTILS_VERSION = arc-2018.09-release
BINUTILS_SITE = ...
BINUTILS_SOURCE = ...
else ifeq ($(BR2_csky),y)
...
else
BINUTILS_VERSION = $(call qstrip,$(BR2_BINUTILS_VERSION))
# Version is set when using buildroot toolchain.
# If not, we do like other packages
ifeq ($(BINUTILS_VERSION),)
BINUTILS_VERSION = 2.31.1
endif
BINUTILS_SITE = ...
BINUTILS_SOURCE = ...
endif


 Obviously, this should be done in two patches: one that refactors the situation
for arc, and a second one that adds csky.

this select.

Why is this option being removed ? This is not explained in the commit

This should be in a separate patch, it's not a change that is directly

Perhaps this is becoming too much, and we should adopt a solution
similar to the one in arch/arch.mk.riscv. I.e, drop the
BR2_GCC_TARGET_CPU definition from arch/Config.in.csky, and add a file
arch/arch.mk.csky that contains:

ifeq ($(BR2_csky),y)

ifeq ($(BR2_ck610),y)
GCC_TARGET_CPU := ck610
else ifeq ($(BR2_ck807),y)
GCC_TARGET_CPU := ck807
else ifeq ($(BR2_ck810),y)
GCC_TARGET_CPU := ck810
else ifeq ($(BR2_ck860),y)
GCC_TARGET_CPU := ck860
endif

ifeq ($(BR2_CSKY_FPU),y)
GCC_TARGET_CPU := $(GCC_TARGET_CPU)f
endif

ifeq ($(BR2_CSKY_VDSP),y)
GCC_TARGET_CPU := $(GCC_TARGET_CPU)v
endif

endif

In fact we haven't used BR2_CSKY_DSP in buildroot, and we change it to
VDSP instead. I'll add commnet in commit log.
