* ARC: configs: Remove CONFIG_INITRAMFS_SOURCE from defconfigsAlexey Brodkin2019-09-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 64234961c145606b36eaa82c47b11be842b21049 upstream. 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.

* arc: [devboards] Add support of NFSv3 ACLAlexey Brodkin2018-12-13
| | | | | | | | | | | | | | | | | | commit 6b04114f6fae5e84d33404c2970b1949c032546e upstream. 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".

* ARC: change defconfig defaults to ARCv2Kevin Hilman2018-12-13
| | | | | | | | | | | | | | | | | | | | | | | commit b7cc40c32a8bfa6f2581a71747f6a7d491fe43ba upstream. Change the default defconfig (used with 'make defconfig') to the ARCv2 nsim_hs_defconfig, and also switch the default Kconfig ISA selection to ARCv2. This allows several default defconfigs (e.g. make defconfig, make allnoconfig, make tinyconfig) to all work with ARCv2 by default. Note since we change default architecture from ARCompact to ARCv2 it's required to explicitly mention architecture type in ARCompact defconfigs otherwise ARCv2 will be implied and binaries will be generated for ARCv2.

* ARC: [plat-axs*]: Enable SWAPAlexey Brodkin2018-09-19
| | | | | | | | | | | | | | | | | commit c83532fb0fe053d2e43e9387354cb1b52ba26427 upstream. SWAP support on ARC was fixed earlier by commit 6e3761145a9b ("ARC: Fix CONFIG_SWAP") so now we may safely enable it on platforms that have external media like USB and SD-card.

* ARC: switch to arc-linux- CROSS_COMPILE prefix across all configssujayraaj2015-11-16
| | | | | | | | | | | | | | 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.
