mmc: fsl: introduce wp_enable
Introudce wp_enable. To check WPSPL, wp_enable needs to be set
to 1 in board code.
Take i.MX6UL for example, for some boards, they do not use WP singal,
so they does not configure USDHC1_WP_SELECT_INPUT, and its default
value is 0(GPIO1_IO02). However GPIO1_IO02 is muxed for i2c usage and
SION bit set. So USDHC controller can always get wp signal and WPSPL
shows write protect and blocks driver continuing. This is not what
we want to see, so add wp_enable, and if set to 0, just omit the
WPSPL checking and this does not effect normal working of usdhc
controller.
If wp-gpios is provided in dts, wp_enable is set to 1, otherwise 0.

The USDHC moves the 4 clock bits CARD_CLK_SOFT_EN, IPG_PERCLK_SOFT_EN,
HCLK_SOFT_EN, and IPG_CLK_SOFT_EN from sysctl register to vendorspec
register. The driver uses RSTA to replace the clock gate off
operation. But this is not a good solution because:
1. when using RSTA, we should wait this bit to clear by itself. This is not
implemeneted in the code.
2. After RSTA is set, it is recommended that the Host Driver reset the
external card and reinitialize it.

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
at the end of the secure section for its stacks. If PSCI is relocated to
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
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
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
section by skipping pages in the linker script, but only when there is
no secure SRAM, to avoid bloating the binary.
This fix is only a stop gap. It would be better to rework the stack
allocation mechanism, maybe with proper usage of CONFIG_ macros and an

we can later load the page and test different ECC configs without the
penalty of reloading the same page in the NAND cache.
We also move common setup to a dedicated function (nand_apply_config()) to
avoid rewriting the same values in NFC registers each time we read a page.
These new functions are passed a pointer to an nfc_config struct to limit
the number of parameters.

spl: nand: sunxi: rework status polling loop
check_value_xxx() helpers are using a 1ms delay between each test, which
can be quite long for some operations (like a page read on an SLC NAND).
Since we don't have anything to do but to poll this register, reduce the
delay between each test to 1us.
While we're at it, rename the max_number_of_retries parameters and the
MAX_RETRIES macro into timeout_us and DEFAULT_TIMEOUT_US to reflect that
we're actually waiting a given amount of time and not only a number of
retries.

spl: nand: sunxi: stop guessing the redundant u-boot offset
Use CONFIG_SYS_NAND_U_BOOT_OFFS_REDUND value instead of trying to guess
where the redundant u-boot image is based on simple (and most of the time
erroneous) heuristics.

spl: nand: support redundant u-boot image
On modern NAND it's more than recommended to have a backup copy of the
u-boot binary to recover from corruption: bitflips are quite common on
MLC NANDs, and the read-disturbance will corrupt your u-boot partitition
more quickly than what you would see on an SLC NAND.
Add an extra Kconfig option to specify the offset of the redundant u-boot
image.
