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
in commit 5da4f857beac ("tools: moveconfig: report when CONFIGs are
removed by savedefconfig").
It would be nice to display the list of suspicious boards when the
tool finishes processing. It is highly recommended to check the

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

and PSCI remains in main memory, the reserved memory space doesn't cover
the space used by the stack.
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

system hanging or telinit core dumping when trying to reboot. It seems

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

test/py: fix printenv signon message disable code
CONFIG_VERSION_VARIABLE isn't always defined, so we can't simply look up
its value directly, or an exception will occur if it isn't defined.
Instead, we must use .get() to supply a default value if the variable
isn't defined.

imx: mx6ulevk: change QSPI PAD DSE to 120ohm
The current pad DSE for QSPI is 60ohm. This setting cause
too strong drive to clock and data signals. Need to change
the DSE to 120ohm for better signal quality.

mx7dsabresd: Fix LCD_PWR_EN output setting
LCD_PWR_EN controls the G pin of Q13 PMOS which needs low voltage to connect
D to S for outputting LCD 3.3V. If LCD_PWR_EN is high, we measured the LCD 3v3
is actually 1.2V.

usb: ehci: only shutdown opened controller
If the usb controller is not running, no need to shutdown it,
otherwise `usb stop` complains about:
"EHCI failed to shut down host controller".
To i.MX7D SDB, there are two usb ports, one Host, one OTG.
If we only plug one udisk to the Host port and then `usb start`,
the OTG controller for OTG port does not run actually. Then,
if `usb stop`, the OTG controller for OTG port will also be
shutdown, but it is not running.
This patch adds a check to only shutdown the running controller.

cmd: usb: check if_type before using this device
For legacy usb storage driver, USB_MAX_STOR_DEV is defined as 7.
If we only have one usb disk on board, `usb dev 0` is ok.
But if `usb dev 1`, still ok, then `usb read xxx` will trigger
system fault and reboot.
So check if_type before using this device.
