8fad5e0b11 spi: atcspi200: avoid NULL dereference
For SPI_XFER_BEGIN | SPI_XFER_END the code sets data_out = NULL.
In the debug statement we should not dereference this value.
As we do not transfer any data the debug statement is not needed in this
case anyway.

409fc029c4 tools: buildman: Don't use the working dir as build dir
When the U-Boot base directory happens to have the same name as the branch
that buildman is directed to use via the '-b' option and no output
directory is specified with '-o', buildman happily starts removing the
whole U-Boot sources eventually only stopped with the error message:

OSError: [Errno 20] Not a directory: '../<branch-name>/boards.cfg

Add a check to avoid this and also deal with the case where '-o' points
to the source directory, or any subdirectory of it.

Finally, tidy up the confusing logic for removing the old tree when using
-b. This is only done when building a branch.

31dd8efeb6 usb: composite convert __set_bit to generic_set_bit
Compiling the f_mass_storage driver for an x86 target results in a
compilation error as set_bit and clear_bit are provided by bitops.h

To address that situation we discussed on the list moving to
genetic_set_bit() instead.

Doing a quick grep for similar situations in drivers/usb shows that the
composite device is using __set_bit().

This patch switches over to generic_set_bit to maintain consistency between
the two gadget drivers.

5ac73f6879 usb: f_mass_storage: Fix set_bit and clear_bit usage
Compiling the f_mass_storage driver for an x86 target results in a
compilation error as set_bit and clear_bit are provided by bitops.h

Looking at the provenance of the current u-boot code and the git change
history in the kernel, it looks like we have a local copy of set_bit and
clear_bit as a hold-over from porting the Linux driver into u-boot.

These days __set_bit and __clear_bit are optionally provided by an arch and
can be used as inputs to generic_bit_set and generic_bit_clear.

This patch switches over to generic_set_bit and generic_clear_bit to
accommodate.

Tested on i.MX WaRP7 and Intel Edison

This syncs drivers/ddr/marvell/a38x/ with the mv_ddr-armada-17.10 branch
of https://github.com/MarvellEmbeddedProcessors/mv-ddr-marvell.git.

The upstream code is incorporated omitting the ddr4 and apn806 and
folding the nested a38x directory up one level. After that a
semi-automated step is used to drop unused features with unifdef

  find drivers/ddr/marvell/a38x/ -name '*.[ch]' | \
    xargs unifdef -m -UMV_DDR -UMV_DDR_ATF -UCONFIG_DDR4 \
		-UCONFIG_APN806 -UCONFIG_MC_STATIC \
		-UCONFIG_MC_STATIC_PRINT -UCONFIG_PHY_STATIC \
		-UCONFIG_64BIT

INTER_REGS_BASE is updated to be defined as SOC_REGS_PHY_BASE.

Some now empty files are removed and the ternary license is replaced
with a SPDX GPL-2.0+ identifier.

EspressoBin).

The basic module can be extended by different modules. The device tree
binary for the kernel can be dependent on which modules are connected,
and in what order. Because of this, the board specific code creates
in U-Boot a variable called module_topology, which carries this
information.

2b69a67389 watchdog: Add support for Armada 37xx CPU watchdog
This adds support for the CPU watchdog found on Marvell Armada 37xx
SoCs.

There are 4 counters which can be set as CPU watchdog counters.
This driver uses the second counter (ID 1, counting from 0)
(Marvell's Linux also uses second counter by default).
In the future it could be adapted to use other counters, with
definition in the device tree.
