In some cases it is useful to compile support for U-Boot command 'wdt'

user want to start the watchdog only on demand by some boot script.
This change adds a new compile option WATCHDOG_AUTOSTART to control whether
U-Boot should automatically start the watchdog during init phase or not.
This option is enabled by default as it was the default behavior prior
introducing this new change. When compiling U-Boot users can decide to turn

We had a problem detecting 8/16bit flash devices connected only via
8bits to the SoC for quite a while. Commit 239cb9d9
[mtd: cfi_flash: Fix CFI flash driver for 8-bit bus support] finally
fixed this 8-bit bus support. But also broke some other boards using
this cfi driver. So this patch had to be reverted.
I spotted a different, simpler approach for this 8-bit bus support
on the barebox mailing list posted by
Oleksij Rempel <bug-track@fisher-privat.net>:
http://www.spinics.net/lists/u-boot-v2/msg14687.html
Here the commit text:
"
Many cfi chips support 16 and 8 bit modes. Most important
difference is use of so called "Q15/A-1" pin. In 16bit mode this
pin is used for data IO. In 8bit mode, it is an address input
which add one more least significant bit (LSB). In this case
we should shift all adresses by one:
For example 0xaa << 1 = 0x154
"
This patch now is a port of this barebox patch to U-Boot.
Along with the change w.r.t from barebox,
Some flash chips can support multiple bus widths, override the
interface width and limit it to the port width.
Tested on 16-bit Spansion flash on sequoia.
Tested 8-bit flashes like 256M29EW, 512M29EW.

The code was trying to disable PCS auto-negotiation when a fixed-link node
is present and enable it otherwise. However, the PCS registers were being
written before the PCSSEL bit was set in the network configuration
register, and it appears that in this state, PCS register writes are
ignored. The result is that the intended change only took effect on the
second network operation that was performed, since at that time PCSSEL is
already enabled.
Fix the order of register writes so that PCS registers are only written to
after the PCS is enabled.

This feature was dropped from U-Boot some time ago:
f12f96cfaf (sf: Drop spl_flash_get_sw_write_prot")
However, we do need a way to see if a flash device is write-protected,
since if it is, it may not be possible to write to do (i.e. failing to
write is expected).
I am not sure of the correct layer to implement this, so this patch is a
stab at it. If spi-flash makes sense then I will add to the 'sf' also.
Re the points mentioned in the removal commit:
1) This kind of requirement can be achieved using existing
flash operations and flash locking API calls instead of
making a separate flash API.
Which uclass is this?
2) Technically there is no real hardware user for this API to
use in the source tree.
I do want coral (at least) to support this.
3) Having a flash operations API for simple register read bits
also make difficult to extend the flash operations.
This new patch only mentions write-protect being on or off, rather than
the actual mechanism.
4) Instead of touching generic code, it is possible to have
this functionality inside spinor operations in the form of
flash hooks or fixups for associated flash chips.
That sounds to me like what drivers are for. But we still need some sort
of API for it to be accessible.

The Intel GPIO binding allows GPIOs to be globally numbered, so that it
does not matter which GPIO bank is specified in the device tree. This is
convenient and avoid confusion since the banks do not have the same number
of GPIOs and the numbering is not sequential.
The GPIO uclass ensures that the device mentioned in the devicetree
binding is probed. It is fine for the driver to update gpio_desc to point
to a different driver, but this may not have been probed. If it has not
been, then it cannot be claimed since there is no uclass data.
We could handle this in the GPIO uclass but so far it is an unusual
situation so it is probably not worth the extra code. Handle this case in
the GPIO driver by probing the selected device if necessary.
