Timeout of 1ms is too low for case when device operates in Full Speed
mode. This causes most incoming frames to be lost.
Since timeout is only used to get out of polling loop in case of no
response from hardware, increasing it should be safe for all platforms.

Otherwise the i2c core will try to populate the TC358767 child nodes
as i2c devices, which is wrong.

Latest version of get_runtime_offset() returns positive offset that
needs to be added to rather than substracted from original pointer.

In some cases it is practical to supervise as much as possible of
the barebox execution with a watchdog (or multiple watchdogs). This
patch provides an async poller for watchdog core framework which can
be enabled by the user and stores this configuration to nv.

the watchdog hwdev is usually named with devicetree schema
which is not practical for CLI.
On device registration "wdog" will be extended with some index number
extracted from devicetree (if awailable) or automatically assigned
first available number. End result will be "wdog0" .. etc.

There are valid cases where there is no way to translate a OF node to
a MMIO address via ranges, so do the same as the Linux kernel and don't
print an error message in that case, but make it available as a debug

Several DDR3 phy registers are written with the pattern x<<30 | x<<20 | x<<10 | x.
The x<<30 doesn't fit into 32bit which causes a compiler warning.
Looking at the reference manual only the lower 10bit of the registers
have any meaning, so drop the other bogus values. This affects the
registers:
AM33XX_DATA0_RD_DQS_SLAVE_RATIO_0
AM33XX_DATA0_WR_DQS_SLAVE_RATIO_0
AM33XX_DATA0_WR_DQS_SLAVE_RATIO_1
AM33XX_DATA0_WRLVL_INIT_RATIO_0
AM33XX_DATA0_GATELVL_INIT_RATIO_0
AM33XX_DATA0_GATELVL_INIT_RATIO_1
AM33XX_DATA0_FIFO_WE_SLAVE_RATIO_0
AM33XX_DATA0_WR_DATA_SLAVE_RATIO_0
(AM33XX_DATA0_WR_DQS_SLAVE_RATIO_1 and AM33XX_DATA0_GATELVL_INIT_RATIO_1
do not even exist according to the reference manual, but that's another
story.)

Reading the manual more carefully discovers a different logic for the
DCD 'check' command. They use the term "until". In order to get the
manual and the software in sync, this change switches to the term
"until" as well. Changing must happen at compiler and interpreter level
to make it work.
