Pull kconfig updates from Michal Marek:
 "Yann E Morin was supposed to take over kconfig maintainership, but
  this hasn't happened.  So I'm sending a few kconfig patches that I
  collected:

   - Fix for missing va_end in kconfig
   - merge_config.sh displays used if given too few arguments
   - s/boolean/bool/ in Kconfig files for consistency, with the plan to
     only support bool in the future"

* 'kconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
  kconfig: use va_end to match corresponding va_start
  merge_config.sh: Display usage if given too few arguments

9298bc7273 spi: spi-fsl-dspi: Remove spi-bitbang
DSPI module need cs change information in
a spi transfer. According to cs change, DSPI
will give last data the right flag. Bitbang
provide cs change behind the last data in
a transfer. So DSPI can not deal the last
data in every transfer properly, so remove
the bitbang in the driver.

75d30c51f8 spi: pl08x: do not select S3C64XX_PL080
The pl08x driver originally selected S3C64XX_PL080 to avoid having
the legacy Samsung DMA interfaces. Those are now gone, so the
select is no longer needed, but it now causes problems when
CONFIG_DMA_ENGINE is disabled:

arch/arm/plat-samsung/built-in.o: In function `s3c64xx_spi0_set_platdata':
:(.init.text+0x518): undefined reference to `pl08x_filter_id'

This simply removes the 'select' to avoid this problem.

c3e4bc5434 spi: meson: Add support for Amlogic Meson SPIFC
This is a driver for the Amlogic Meson SPIFC (SPI flash controller),
which is one of the two SPI controllers available on the SoC. It
doesn't support DMA and has a 64-byte unified transmit/receive buffer.

The device is optimized for interfacing with SPI NOR memories and
allows the execution of standard operations such as read, page
program, sector erase, etc. in a simplified way, toggling a bit in a
dedicated register. The driver doesn't use those predefined commands
and relies only on custom transfers.

Broadcom 53xx ARM SoCs use bcma bus that contains various cores (AKA

bus0: Found chip with id 53010, rev 0x00 and package 0x02
(...)
bus0: Core 18 found: SPI flash controller (manuf 0x4BF, id 0x50A, rev 0x01, class 0x0)

This patch adds a bcma driver for SPI core, it registers SPI master
controller and "bcm53xxspiflash" SPI device.

As of commit ab116a4df4 ("dmaengine:
shdma: fix a build failure on platforms with no DMA support"), the DMA
filter function shdma_chan_filter() is sufficiently abstracted to allow
building without DMA support. Hence drop the SH_DMAE_BASE dependency on
SUPERH.
Also increase build coverage by allowing the driver to be enabled if
COMPILE_TEST=y.

766e372199 spi: convert spi-bfin-v3.c to a multiplatform driver
Spi v3 controller is not only used on Blackfin. So rename it
and use ioread/iowrite api to make it work on other platform.

058f11c851 spi: qup: Depend on ARCH_QCOM
Commit 8fc1b0f87d ("ARM: qcom: Split Qualcomm support into legacy and
multiplatform") removed Kconfig symbol ARCH_MSM_DT. But that commit
left one (optional) dependency on ARCH_MSM_DT untouched.

Three Kconfig symbols used to depend on ARCH_MSM_DT: ARCH_MSM8X60,
ARCH_MSM8960, and ARCH_MSM8974. These three symbols now depend on
ARCH_QCOM. So it appears this driver needs to depend on ARCH_QCOM too.

6840cc29f2 spi: add xtfpga SPI controller driver
This simple SPI master controller is built into xtfpga bitstreams. It
always transfers 16 bit words in SPI mode 0, automatically asserting CS
on transfer start and deasserting on end.
