For sandbox we have a fallback console which is used very early in
U-Boot, before serial drivers are available. Rather than try to guess
when to switch to the real console, add a flag so we can be sure. This
makes sure that sandbox can always output a panic() message, for example,
and avoids silent failure (which is very annoying in sandbox).

At present stdio device functions do not get any clue as to which stdio
device is being acted on. Some implementations go to great lengths to work
around this, such as defining a whole separate set of functions for each
possible device.
For driver model we need to associate a stdio_dev with a device. It doesn't
seem possible to continue with this work-around approach.
Instead, add a stdio_dev pointer to each of the stdio member functions.
Note: The serial drivers have the same problem, but it is not strictly
necessary to fix that to get driver model running. Also, if we convert
serial over to driver model the problem will go away.
Code size increases by 244 bytes for Thumb2 and 428 for PowerPC.

If CONFIG_OMAP1610 is defined, the code returning the fixed value (26)
is enabled. But this case is covered by the following code.
(CONFIG_SYS_NS16550_CLK + (gd->baudrate * (MODE_X_DIV / 2))) /
(MODE_X_DIV * gd->baudrate)
= (48000000 + (115200 * (16 / 2))) / (16 * 115200)
= 48921600 / 1843200
= 26
The "#ifdef CONFIG_OMAP1610" was added by commit 6f21347d more than
ten years ago. In those days, the divide-and-round was not used.
I guess that is why this weird code was added here.

Bit 7 of UCR3 is described in the i.MX3x/i.MX5x/i.MX6x
reference manuals as follows:
Autobaud Detection Not Improved-. Disables new features of
autobaud detection (See Baud Rate Automatic Detection
Protocol, for more details).
0 Autobaud detection new features selected
1 Keep old autobaud detection mechanism
On at least i.MX6DQ, i.MX6DLS and i.MX53, the "new features"
occasionally cause the receiver to get out of sync and
continuously produce received characters of '\xff'.
This patch disables the "new feature" on all boards, since
there's no support for auto-baud in U-Boot on any of them.
More details are available in this post on i.MX Community:

gd->bd->bi_baudrate is a copy of gd->baudrate.
Since baudrate is a common feature for all architectures,
keep gd->baudrate only.
It is true that bi_baudrate was passed to the kernel in that structure
