CRIS: Drop support for the CRIS port

2018-03-16T09:56:05+00:00

The port was added back in 2000 so it's no longer even a good source
of inspiration for newer ports (if it ever was)

The last SoC (ARTPEC-3) with a CRIS main CPU was launched in 2008.

Coupled with time and working developer board hardware being
in low supply, it's time to drop the port from Linux.

So long and thanks for all the fish!

UAPI: Partition the header include path sets and add uapi/ header directories

2012-10-02T17:01:26+00:00

Partition the header include path flags into two sets, one for kernelspace
builds and one for userspace builds.

Add the following directories to build after the ordinary include directories
so that #include will pick up the UAPI header directly if the kernel header
has been moved there.

The userspace set (represented by the USERINCLUDE make variable) contains:

	-I $(srctree)/arch/$(hdr-arch)/include/uapi
	-I arch/$(hdr-arch)/include/generated/uapi
	-I $(srctree)/include/uapi
	-I include/generated/uapi
	-include $(srctree)/include/linux/kconfig.h

and the kernelspace set (represented by the LINUXINCLUDE make variable)
contains:

	-I $(srctree)/arch/$(hdr-arch)/include
	-I arch/$(hdr-arch)/include/generated
	-I $(srctree)/include
	-I include		--- if not building in the source tree

plus everything in the USERINCLUDE set.

Then use USERINCLUDE in building the x86 boot code.

arm, cris, mips, sparc, powerpc, um, xtensa: fix build with bash 4.0

2009-09-20T10:28:22+00:00

Albin Tonnerre  reported:

    Bash 4 filters out variables which contain a dot in them.
    This happends to be the case of CPPFLAGS_vmlinux.lds.
    This is rather unfortunate, as it now causes
    build failures when using SHELL=/bin/bash to compile,
    or when bash happens to be used by make (eg when it's /bin/sh)

Remove the common definition of CPPFLAGS_vmlinux.lds by
pushing relevant stuff to either Makefile.build or the
arch specific kernel/Makefile where we build the linker script.

This is also nice cleanup as we move the information out where
it is used.

Notes for the different architectures touched:

arm - we use an already exported symbol
cris - we use a config symbol aleady available
       [Not build tested]
mips - the jiffies complexity has moved to vmlinux.lds.S where we need it.
       Added a few variables to CPPFLAGS - they are only used by
       the linker script.
       [Not build tested]
powerpc - removed assignment that is not needed
          [not build tested]
sparc - simplified it using $(BITS)
um - introduced a few new exported variables to deal with this
xtensa - added options to CPP invocation
         [not build tested]

CRIS: Merge machine dependent boot/compressed and boot/rescue

2009-04-21T09:44:57+00:00

Merge the machine dependent boot directories for v10 and v32.
This avoids some code duplication and eases the way for further
merging later on.

[CRIS] Remove links from CRIS build

2008-10-31T22:37:57+00:00

Remove the links to architecture and machine dependent directories
(boot, lib, drivers, arch, mach)

The links were created and used mostly from the arch/cris/Makefile,
so why not dispense with them altogether?
Changed $(ARCH) to "cris" in Makefile, it is easier to read this way.

The CRISv32 head.S common files for the kernel and compressed images
needed to be modified to use ifdefs instead of using the now removed
mach link. Since there are only two versions, this is not a huge loss
in readability.

The link to vmlinux.lds.S is also replaced with a merged version
which uses ifdefs to select the correct layout.
System.map before and after are identical.

[CRIS] Merge asm-offsets.c for both arches into one file.

2008-10-31T22:37:00+00:00

Eliminates the link to arch specific asm-offsets.c from CRIS
architecture build system.

Resulting asm-offsets.s are identical before and after change
for both arch-v10 and arch-v32.

[CRIS] Move header files from include to arch/cris/include.

Remove some unneeded headers for arch-v32.

CRIS: proper defconfig setup

2008-10-13T19:34:55+00:00

This patch moves the cris defconfigs to arch/cris/configs/ where they
belong.

As a side effect they can now be used directly through e.g.
  make ARCH=cris artpec_3_defconfig

The default defconfig is set through KBUILD_DEFCONFIG.

CRIS: Update main Kbuild makefile.

2008-02-08T10:06:25+00:00

- Remove old and non-generic targets, use generic ones instead.
- Add sub-arch as mach-fs or mach-a3 for EtraxFS and Artpec-3 respectively.
- Add links to sub-arch directories, and erase before trying to create them.
- Include from sub-arch specific include directory "mach".
- Add files to be cleaned in CLEAN_FILES instead of as archclean target.
