common: Pass the boot device into spl_boot_mode()
The SPL code already knows which boot device it calls the spl_boot_mode()

spl_boot_mode() avoid invoking spl_boot_device() again, but it also lets
board_boot_order() correctly alter the behavior of the boot process.

tools: moveconfig: show suspicious boards with possible misconversion
There are some cases where config options are moved, but they are
ripped off at the final savedefconfig stage:
- The moved option is not user-configurable, for example, due to
a missing prompt in the Kconfig entry
- The config was not defined in the original config header despite
the Kconfig specifies it as non-bool type
- The config define in the header contains reference to another
macro, for example:
#define CONFIG_CONS_INDEX (CONFIG_SYS_LPC32XX_UART - 2)
The current moveconfig does not support recursive macro expansion.
In these cases, the conversion is very likely to be an unexpected
result. That is why I decided to display the log in yellow color

net: rtl8169: fix switching between adapters
The rtl8169 driver uses a global variable to store the register address
of the adapter being operated upon. This is updated to point at the
correct adapter when sending or receiving a packet, or shutting down the
adapter, but not when initializing the adapter. Consequently, switching
between different adapters within the same U-Boot runtime does not work
correctly since the driver programs the wrong registers during
rtl8169_eth_start() -> rtl8169_common_start() -> rtl8169_hw_start().
Note that since rtl8169_eth_stop() does set the global variable, the
second consecutive attempt to use the "new" adapter did work even before
this patch, because each time network usage is shut down, the network
core calls stop, which sets the variable so that the next start does
actually initialize the hardware, and the adapter works.
Equally, rtl8169_eth_probe() calls rtl_init() which sets the global, so
if using only a single device, or if picking the "right" device (based on
probe order) when multiple devices are present, ioaddr will already be set
correctly from the get-go, so the issue does not occur.

ARM: allocate extra space for PSCI stack in secure section during link phase
The PSCI implementation expects at most 2 pages worth of space reserved

secure SRAM, then everything is fine. If no secure SRAM is available,
and PSCI remains in main memory, the reserved memory space doesn't cover

If one accesses PSCI after Linux has fully booted, the memory that should
have been reserved for the PSCI stacks may have been used by the kernel
or userspace, and would be corrupted. Observed after effects include the
system hanging or telinit core dumping when trying to reboot. It seems
the init process gets hit the most on my test bed.
This fix allocates the space used by the PSCI stacks in the secure

spl: nand: sunxi: remove support for so-called 'syndrome' mode
The sunxi SPL NAND controller driver supports use 'BootROM'-like configs,
that is, configs where the ECC bytes and real data are interleaved in the
page instead of putting ECC bytes in the OOB area.
Doing that has several drawbacks:
- since you're interleaving data and ECC bytes you can't use the whole page
otherwise you might override the bad block marker with non-FF bytes.
- to solve the bad block marker problem, the ROM code supports partially
using the page, but this introduces a huge penalty both in term of read
speed and NAND memory usage. While this is fine for rather small
binaries(like the SPL one which is at maximum 24KB large), it becomes
non-negligible for the bootloader image (several hundred of KB).
- auto-detection of the page size is not reliable (this is in my opinion
the biggest problem). If you get the page size wrong, you'll end up
reading data at a different offset than what was specified by the caller
and the reading may succeed (if valid data were written at this address).
For all those reasons I think it's wiser to completely remove support for
'syndrome' configs. If we ever need to support it again, then I'd recommend
specifying all the config parameters through Kconfig options.

* Clocks are now identified with a single "struct clk", rather than

lib/libfdt/: General aesthetic/style fixes.
A number of style fixes across the files in this directory, including:
* Correct invalid kernel-doc content.
* Tidy up massive comment in fdt_region.c.
* Use correct spelling of "U-Boot".
* Replace tests of "! <var>" with "!<var>".

A bug in the pca953x driver prevents correct reading of GPIO input
values beyond the 8th GPIO; all values are reported as zero. Setting of
GPIO output values is not affected.
This patch fixes the reading behavior.

ARM: uniphier: reserve memory for DRAM PHY training on PH1-LD20
The DRAM PHY layer on PH1-LD20 is able to calibrate PHY parameters
periodically. This compensates for the voltage and temperature
deviation and improves the PHY parameter adjustment. Instead, it
requires 64 byte scratch memory in each DRAM channel for the dynamic
training. The memory regions must be reserved in DT before jumping
to the kernel.
The scratch area can be anywhere in each DRAM channel, but the DRAM
init code in SPL currently assigns it at the end of each channel.
So, it makes sense to reserve the regions on run-time by U-Boot
instead of statically embedding it in the DT in Linux. Anyway,
a boot-loader should know much more about memory initialization
than the kernel.

ARM: uniphier: change CPU_RELEASE_ADDR to the head of DRAM space
At first, 256 byte of the head of DRAM space was reserved for some
reasons. However, as the progress of development, it turned out
unnecessary, and it was never used in the end. Move the CPU release
address to leave no space.

CONFIG_VERSION_VARIABLE isn't always defined, so we can't simply look up
