ARC: [plat-hsdk]: Enable AXI DW DMAC in defconfig

2019-07-08T08:24:47+00:00

For some reasons my previous patch "Enable AXI DW DMAC support"
was applied only partially (only device tree part).
So enable AXI DW DMAC in HSDK defconfig to be able to use it in
verification flow.

ARC: [plat-hsdk]: enable DW SPI controller

2019-07-08T08:24:46+00:00

HSDK SoC has DW SPI controller. Enable it in preparation of
enabling on-board SPI peripherals.

ARC: [haps] Add Virtio support

2019-07-08T08:24:45+00:00

As a preparation for QEMU usage for ARC let's add basic Virtio-MMIO
peripherals support for the platform we're going to use.

For now we add 5 Virtio slots in .dts and enable block and network devices
via Virtio-MMIO.

Note even though typically Virtio register set fits in 0x200 bytes
we "allocate" here 0x2000 so that it matches ARC's default 8KiB page size
and so remapping of that area is done clearly.

We also enable DEVTMPFS automount for more convenient use
of external root file-stystem. Before that we used to use built-in
Initramfs which didn't automount DEVTMPFS anyways so we didn't need
that option, while now it starts making sense.

kbuild: add CONFIG_HEADERS_INSTALL and loosen the dependency of samples

2019-06-15T10:57:01+00:00

Commit 5318321d367c ("samples: disable CONFIG_SAMPLES for UML") used
a big hammer to fix the build errors under the samples/ directory.
Only some samples actually include uapi headers from usr/include.

Introduce CONFIG_HEADERS_INSTALL since 'depends on HEADERS_INSTALL' is
clearer than 'depends on !UML'. If this option is enabled, uapi headers
are installed before starting directory descending.

I added 'depends on HEADERS_INSTALL' to per-sample CONFIG options.
This allows UML to compile some samples.

ARC: [plat-hsdk]: Add support of Vivante GPU

HSDK board has built-in Vivante GPU IP which works perfectly fine
with Etnaviv driver, so let's use it.

block: remove CONFIG_LBDAF

2019-04-06T16:48:35+00:00

Currently support for 64-bit sector_t and blkcnt_t is optional on 32-bit
architectures.  These types are required to support block device and/or
file sizes larger than 2 TiB, and have generally defaulted to on for
a long time.  Enabling the option only increases the i386 tinyconfig
size by 145 bytes, and many data structures already always use
64-bit values for their in-core and on-disk data structures anyway,
so there should not be a large change in dynamic memory usage either.

Dropping this option removes a somewhat weird non-default config that
has cause various bugs or compiler warnings when actually used.

configs: get rid of obsolete CONFIG_ENABLE_WARN_DEPRECATED

2019-03-08T02:32:02+00:00

This Kconfig option was removed during v4.19 development in commit
771c035372a0 ("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----------------------
