Reduce the function code by calling xilinx_pm_request() once only.
Use the same variable bsize_req to store either bstream size in bytes
or an address of bstream size according to a type required by the
firmware version. Remove obsolete debug().

0001a964b8 drivers: xen: unmap Enlighten page before jumping to Linux
This commit fixes issue with usage of Xen hypervisor shared info page.
Previously U-boot did not unmap it at the end of OS boot process. Xen
did not prevent guest from this. So, it worked, but caused wierd
issues - one memory page, that was returned by memalign in U-boot
for Enlighten mapping was not unmaped by Xen (shared_info values was
not removed from there) and returned to allocator. During the Linux
boot, it uses shared_info page as regular RAM page, which leads to
hypervisor shared info corruption.

So, to fix this issue, as discussed on the xen-devel mailing list, the
code should:
   1) Unmap the page
   2) Populate the area with memory using XENMEM_populate_physmap

This patch adds page unmapping via XENMEM_remove_from_physmap, fills
hole in address space where page was mapped via XENMEM_populate_physmap
and return this address to memory allocator for freeing.

90ba25b7cb mtd: decommission the NAND museum
Upstream linux commit f7025a43a9da26.

The MTD subsystem has its own small museum of ancient NANDs in a form of
the CONFIG_MTD_NAND_MUSEUM_IDS configuration option. The museum contains
stone age NANDs with 256 bytes pages, as well as iron age NANDs with 512
bytes per page and up to 8MiB page size.

It is with great sorrow that I inform you that the museum is being
decommissioned. The MTD subsystem is out of budget for Kconfig options and
already has too many of them, and there is a general kernel trend to
simplify the configuration menu.

We remove the stone age exhibits along with closing the museum

REMARK Don't apply this part from upstream:

Some of the iron age ones are transferred to the regular NAND depot.
Namely, only those which have unique device IDs are transferred, and the
ones which have conflicting device IDs are removed.

Rework the nand_get_flash_type() function to get rid of this extra
parameter and let detection code directly set the NAND_BUSWIDTH_16 flag in
chip->options if needed.

35ed176af2 arch: mvebu: Disable by default unused peripherals in SPL
SPL on mvebu loads proper U-Boot from custom Marvell kwbimage format and
therefore support for other binary formats is not required to be present in
SPL. Boot source of proper U-Boot is defined by compile time options and
therefore it is not required to enable all possible and unused peripherals
in SPL by default.

This change decrease size of SPL binaries.

1fc45d6483 watchdog: add pulse support to gpio watchdog driver
A common external watchdog circuit is kept alive by triggering a short
pulse on the reset pin. This patch adds support for this use case, while
making the algorithm configurable in the devicetree.

The "linux,wdt-gpio" driver being modified is based off the equivalent
driver in the Linux kernel, which provides support for this algorithm.
This patch brings parity to this driver, and is kept aligned with
the functionality and devicetree configuration in the kernel.

It should be noted that this adds a required property named 'hw_algo'
to the devicetree binding, following suit with the kernel. I'm happy to
make this backward-compatible if preferred.

1aa2b85810 watchdog: octeontx_wdt: Add MIPS Octeon support
This patch adds support for the Marvell Octeon watchdog driver, which
currently only support the ARM64 Octeon TX & TX2 platforms. Since the
IP is pretty similar, it makes sense to extend this driver to also
support the MIPS Octeon SoC.

A follow-up patch will enable this watchdog support on the EBB7304
eval board.

To quote Andre:

One prominent feature is the restructering of the clock driver, which
allows to end up with one actual driver for all variants, although we
still only compile in support for one SoC.
Also contained are some initial SPI fixes, which should fix some
problems, and enable SPI flash support for the F1C100s SoC. Those
patches revealed more problems, I will queue fixes later on, but for
now it should at least still work.
Apart from some smaller fixes (for instance for NAND operation), there
is also preparation for the upcoming Allwinner D1 support, in form of
the USB PHY driver. There are more driver support patches to come.

The gitlab CI completed successfully, including the build test for all
160 sunxi boards. I also boot tested on a few boards, but didn't have
time for more elaborate tests this time.

49f3a42edf i2c: avoid dynamic stack use in dm_i2c_write
The size of the dynamic stack allocation here is bounded by the if()
statement. However, just allocating the maximum size up-front and
doing malloc() if necessary avoids code duplication (the
i2c_setup_offset() until the invocation of ->xfer), and generates much
better (smaller) code:

bloat-o-meter drivers/i2c/i2c-uclass.o.{0,1}
add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-144 (-144)
Function                                     old     new   delta
dm_i2c_write                                 552     408    -144
Total: Before=3828, After=3684, chg -3.76%

It also makes static analysis of maximum stack usage (using the .su
files that are automatically generated during build) easier if there
are no lines saying "dynamic".

[This is not entirely equivalent to the existing code; this now uses
the stack for len <= 64 rather than len <= 63, but that seems like a
more natural limit.]
