Masahiro Yamada 15f5db60a1 kbuild,arc: add CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE_O3 for ARC
arch/arc/Makefile overrides -O2 with -O3. This is the only user of
ARCH_CFLAGS. There is no user of ARCH_CPPFLAGS or ARCH_AFLAGS.
My plan is to remove ARCH_{CPP,A,C}FLAGS after refactoring the ARC
Makefile.

Currently, ARC has no way to enable -Wmaybe-uninitialized because both
-O3 and -Os disable it. Enabling it will be useful for compile-testing.
This commit allows allmodconfig (, which defaults to -O2) to enable it.

Add CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE_O3=y to all the defconfig files
in arch/arc/configs/ in order to keep the current config settings.

Alexey Brodkin 3337d5cfe5 configs: get rid of obsolete CONFIG_ENABLE_WARN_DEPRECATED
This Kconfig option was removed during v4.19 development in commit
771c035372 ("deprecate the '__deprecated' attribute warnings entirely
and for good") so there's no point to keep it in defconfigs any longer.

FWIW defconfigs were patched with:
--------------------------->8----------------------
find . -name *_defconfig -exec sed -i '/CONFIG_ENABLE_WARN_DEPRECATED/d' {} \;
--------------------------->8----------------------

Alexey Brodkin 6b04114f6f arc: [devboards] Add support of NFSv3 ACL
By default NFSv3 doesn't support ACL (Access Control Lists)
which might be quite convenient to have so that
mounted NFS behaves exactly as any other local file-system.

In particular missing support of ACL makes umask useless.
This among other thigs fixes Glibc's "nptl/tst-umask1".

Alexey Brodkin c83532fb0f ARC: [plat-axs*]: Enable SWAP
SWAP support on ARC was fixed earlier by
commit 6e3761145a ("ARC: Fix CONFIG_SWAP")
so now we may safely enable it on platforms that
have external media like USB and SD-card.

Note: it was already allowed for HSDK

Alexey Brodkin 4051c323c5 ARC: configs: cleanup
- Remove CONFIG_DEFAULT_HOSTNAME from defconfigs

   There's no reason to set the same hostname to all ARC boards
   by default. It usually gets overwritten by init scripts anyways.

 - Remove disabled CONFIG_DEVKMEM from defconfigs

   It is disabled by default

Alexey Brodkin 64234961c1 ARC: configs: Remove CONFIG_INITRAMFS_SOURCE from defconfigs
We used to have pre-set CONFIG_INITRAMFS_SOURCE with local path
to intramfs in ARC defconfigs. This was quite convenient for
in-house development but not that convenient for newcomers
who obviusly don't have folders like "arc_initramfs" next to
the Linux source tree. Which leads to quite surprising failure
of defconfig building:
------------------------------->8-----------------------------
  ../scripts/gen_initramfs_list.sh: Cannot open '../../arc_initramfs_hs/'
../usr/Makefile:57: recipe for target 'usr/initramfs_data.cpio.gz' failed
make[2]: *** [usr/initramfs_data.cpio.gz] Error 1
------------------------------->8-----------------------------

So now when more and more people start to deal with our defconfigs
let's make their life easier with removal of CONFIG_INITRAMFS_SOURCE.

Commit 92e5aae457 "kernel/watchdog: split up config options"
introduced SOFTLOCKUP_DETECTOR which selects LOCKUP_DETECTOR
instead of the latter to be selected itself.

We need to adjust our defconfigs accordingly.

Alexey Brodkin 7badf6fefc ARC: axs10x: really enable ARC PGU
Up until now we had ARC PGU not enabled in axs10x defconfigs trying
to not bloat kernel image again with yet another drivers and subsystems.

This change configures ARC PGU (as well as DRM bits it depends on)
to be built as a module and so those who need LCD screen to work on
axs10x may bundle built .ko files in their target's file-system with
help of the following command on host:
------------->8-------------
make INSTALL_MOD_PATH=_path_to_target_fs_ modules_install
------------->8-------------

and later on target with commands as simple as:
------------->8-------------
modprobe adv7511.ko
modprobe arcpgu.ko
------------->8-------------
get LCD working.

Alexey Brodkin 0dee6c82c2 ARC: [plat-axs103] Enable loop block devices
As mentioned in LTP's README.ARC:
------------->8------------
 Requirements for the environment

* Linux must be built with support of loop block devices. Thus it's
  necessary to enable these Linux kernel options:
  CONFIG_BLK_DEV
  CONFIG_BLK_DEV_LOOP
------------->8------------
enabling loop block devices.

That among other things lead to additional 10 fatal signals
appearing during LTP run.

Vineet Gupta 2d746eeb4f ARC: [*defconfig] No need to specify CONFIG_CROSS_COMPILE
The problem is with CONFIG_CPU_BIG_ENDIAN=y we still needed .config
fixup to override the the defconfig prefix to arceb-linux-

So remove these from defconfig and let user pass this via CROSS_COMPILE
environment var or use the default for ENDIAN (per previous patch)

No other arch carries them in defconfigs anyways !

Alexey Brodkin 3e5177c191 arc: get rid of DEVTMPFS dependency on INITRAMFS_SOURCE
Even though DEVTMPFS is required when our pre-built initramfs
is used it is not the case in general. It is perfectly possible
to use initramfs with device nodes already populated or there
could be other usages, see discussion below for more detials:
http://thread.gmane.org/gmane.comp.embedded.openwrt.devel/37819/focus=37821

This change removes mentioned dependency from arch/arc/Kconfig
updating instead those defconfigs that are usually used with this
kind of pre-build initramfs.

And while at it all touched defconfigs were regenerated via
savedefconfig and some options were removed:
 * USB is selected by other options implicitly
 * VGA_CONSOLE is disableb for ARC since
   031e29b587
 * EXT3_FS automatically selects EXT4_FS
 * MTDxxx and JFFS2_FS make no sense for AXS because
   AXS NAND controller is not upstreamed
 * NET_OSCI_LAN is not in upstream as well
 * ARCPGU_xxx options make no sense because ARC PGU is not yet
   in upstream and when it gets there all config options would
   be taken from devicetree

sujayraaj 17c4fbaf1a ARC: switch to arc-linux- CROSS_COMPILE prefix across all configs
When building kernel with buildroot built toolchain, CROSS_COMPILE
currently needs adjustment even if minor. This is because the defconfigs
prefer "arc-linux-uclibc-" prefix from hand built (non buildroot) toolchain
while buildroot provides "arc-buildroot-linux-uclibc-"

To avoid this use the common "arc-linux-" prefix which is provided by
buildroot and has also been in hand built tools for quite some time.
