This patch adds a limited pulse-width modulator to sandbox's Chromium OS
Embedded Controller emulation. The emulated PWM device supports multiple
channels but can only set a duty cycle for each, as the actual EC
doesn't expose any functionality or information other than that. Though
the EC supports specifying the PWM channel by its type (e.g. display
backlight, keyboard backlight), this is not implemented in the emulation
as nothing in U-Boot uses this type specification.
This emulated PWM device is then used to test the Chromium OS PWM driver
in sandbox. Adding the required device node to the sandbox test
device-tree unfortunately makes it the first PWM device, so this also
touches some other tests to make sure they still use the sandbox PWM.

If there were no variable substitutions in a command, then initial
assignments would be misinterpreted as commands, instead of being skipped
over. This is demonstrated by the following example:
=> foo=bar echo baz
Unknown command 'foo=bar' - try 'help'

At present we use the linker list directly. This is not very friendly, so
add a helpful macro instead. This will also allow us to change the naming
later without updating this code.

This prefix should be for setexpr, not mem. This means that trying to
select just these tests to run does not work. Fix it.
For some reason this provokes an assertion failure due to memory not
being freed. Move the env_set() in setexpr_test_str() to before the
malloc() heap size size is recorded and disable the rest in
setexpr_test_str_oper().

Move this out of the common header and include it only where needed. In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly. Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

At present when more than one substitution is made this function
overwrites its buffers. Fix this bug and update the tests now that they
can pass.
Also update the debug code to show all substrings, since at present it
omits the final one.

At present the 'nlen' variable increases with each loop. If the previous
loop had back references, then subsequent loops without back references
use the wrong value of nlen. The value is larger, meaning that the string
terminator from nbuf is copied along to the main buffer, thus terminating
the string prematurely.
This leads to the final result being truncated, e.g. missing the last
(unmatched) part of the string. So "match match tail" become
"replaced replaced" instead of "replaced replaced tail".
Fix this by resetting nlen to the correct value each time around the lop.

At present this function assumes that a size of 4 refers to a ulong. This
is true on 32-bit machines but not commonly on 64-bit machines.
This means that the 'l' specify does not work correctly with setexpr.
Add an explicit case for 32-bit values so that 64-bit machines can still
use the 'l' specifier. On 32-bit machines, 64-bit is still not supported.
This corrects the operation of the default size (which is 4 for setexpr),
so update the tests accordingly.
The original code for reading from memory was included in 47ab5ad145
("cmd_setexpr: allow memory addresses in expressions") but I am not adding
a Fixes: tag since that code was not written with 64-bit machines in mind.

This command currently has no tests. Add some for basic assignment and the
integer operations.
Note that the default size for setexpr is ulong, which varies depending on
the build machine. So for sandbox on a 64-bit host, this means that the
default size is 64 bits.

It is useful to be able to find hex values and strings in a memory range.
Add a command to support this.
cmd: Fix 'md' and add a memory-search command
At present 'md.q' is broken. This series provides a fix for this. It also
implements a new memory-search command called 'ms'. It allows searching
