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).

The current functions for adding and removing devices require a device name.
This is not convenient for driver model, which wants to store a pointer to
the relevant device. Add new functions which provide this feature and adjust
the old ones to call these.

Initialise devices marked 'pre-reloc' and make them available prior to
relocation. Note that this requires pre-reloc malloc() to be available.

Driver model currently only operates after relocation is complete. In this
state U-Boot typically has a small amount of memory available. In adding
support for driver model prior to relocation we must try to use as little
memory as possible.
In addition, on some machines the memory has not be inited and/or the CPU
is not running at full speed or the data cache is off. These can reduce
execution performance, so the less initialisation that is done before
relocation the better.
An immediately-obvious improvement is to only initialise drivers which are
actually going to be used before relocation. On many boards the only such
driver is a serial UART, so this provides a very large potential benefit.
Allow drivers to mark themselves as 'pre-reloc' which means that they will
be initialised prior to relocation. This can be done either with a driver
flag or with a 'dm,pre-reloc' device tree property.
To support this, the various dm scanning function now take a 'pre_reloc_only'
parameter which indicates that only drivers marked pre-reloc should be
bound.

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.

Enable this for sandbox so that we will be able to use driver model before
relocation.

If we are to have driver model before relocation we need to support some
way of calling memory allocation routines.
The standard malloc() is pretty complicated:
1. It uses some BSS memory for its state, and BSS is not available before
relocation
2. It supports algorithms for reducing memory fragmentation and improving
performace of free(). Before relocation we could happily just not support
free().
3. It includes about 4KB of code (Thumb 2) and 1KB of data. However since
this has been loaded anyway this is not really a problem.
The simplest way to support pre-relocation malloc() is to reserve an area
of memory and allocate it in increasing blocks as needed. This
implementation does this.
To enable it, you need to define the size of the malloc() pool as described
in the README. It will be located above the pre-relocation stack on
supported architectures.
Note that this implementation is only useful on machines which have some
memory available before dram_init() is called - this includes those that
do no DRAM init (like tegra) and those that do it in SPL (quite a few
boards). Enabling driver model preior to relocation for the rest of the
boards is left for a later exercise.

When this option is enabled, CRLF is treated like LF when importing environments
from text files, which means CRs ('\r') in front of LFs ('\n') are just ignored.
Drawback of enabling this option is that (maybe exported) variables which have
a trailing CR in their content will get imported without that CR. But this
drawback is very unlikely and the big advantage of letting Windows user create
a *working* uEnv.txt too is likely more welcome.

[backport from linux commit 204b885e and 218e180e7]
64 bit processors are becomming more and more popular.
lower_32_bits and upper_32_bits save our labor doing
shifts/manipulations like (u32)(n) and (u32)((n) >> 32).
They are good helpers in both little and big endian cases.
Port these two functions here from Linux:include/linux/kernel.h,
cater the comment message to little/big endian cases.
Later on, developers could include linux/compat.h if they want to
use these two functions.

When static inline is used in a header file the function
should preferably be inlined and if not possible made a
static function. When declared inside a c file there is a
static function, which might be inlined. Since SPL uses a
define to declare the static inline it becomes part of the
c file although it is declared in a header and clang will
warn that you have introduced unused static functions. Add
maybe_unused to prevent such warnings.

Similar to the USB NIC found on OMAP5uEVM, PandaBoard and BeagleBoard-XM
boards, the sunxi SoCs have a NIC onboard without an embedded MAC address.
Just like the omap used on these boards, the sunxi SoCs do have a unique chip
id, in the form of the 128 bit SID register:
http://linux-sunxi.org/SID_Register_Guide
So mimick the BeagleBoard-XM board code (commit 548a64d8) and use the chip id
to generate a unique fixed MAC address.
We check for the SID not being all 0, since some early A20 batches
shipped without having there SID programmed.
Note we use specific parts of the 128 bits, since some parts indicate the
SoC family / revision, and thus are fixed. The algorithm for this was taken
from the linux-sunxi.org kernels.
