d84e3d2630 bios_emulator: define the comment symbol for RISC-V assembler too
The bios_emulator driver cannot be compiled for RISC-V because the x86emu.h
header file doesn't define the comment symbol ("#") for the assembler.
With this patch, use the same symbol as for e.g. x86.

cb3ce95401 global: Drop common.h inclusion
In order to make it easier to move on to dropping common.h from code
directly, remove common.h inclusion from the rest of the header file
which had been including it.

1e94b46f73 common: Drop linux/printk.h from common header
This old patch was marked as deferred. Bring it back to life, to continue
towards the removal of common.h

Move this out of the common header and include it only where needed.

b44b30260f printk: collect printk stuff into <linux/printk.h> with loglevel support
When we import code from Linux, with regular re-sync planned, we want
to use printk() and pr_*().  U-Boot does not support them in a clean
way.  So, people end up with local macros, or compat headers here and
there, then we occasionally see build errors of definition conflicts.

We have include/linux/compat.h, but putting all sorts of unrelated
things into a single header is just a temporal workaround.  Hence this
patch, to find the best home for all printk variants.  If you want to
use printk() and friends, please include <linux/printk.h>.  This header
is self-contained, and pulls in only a few headers.

When I was testing this clean-up, I noticed the image size exceeded
its platform limit on some boards.  This is because all pr_*() that
were previously defined as no-op in include/linux/mtd/mtd.h (unless
CONFIG_MTD_DEBUG is set), are now enabled.

To make such boards happy, this commit also implements CONFIG_LOGLEVEL.
The concept is similar to the kernel parameter "loglevel".  (Actually,
the Kconfig help message was taken from kernel-paremeter.txt of Linux)
Messages with a loglevel smaller than console loglevel will be printed.

The difference is the loglevel is build-time determined.  To save the
image size, lower priority pr_*() are compiled out.  I set the default
of CONFIG_LOGLEVEL to 6, i.e. pr_notice and higher priority messages
are compiled in.

I adjusted CONFIG_LOGLEVEL to avoid build error for some boards.

8c6ec412b4 bios_emulator: Always print errors when opcode decode fails
This is a rare event and should not happen. When it does it is confusing to
work out why. At least we should print a message.

Adjust the emulator to always print decode errors to the console.

b3521f2e49 bios_emulator: Add an option to enable debugging
At present there are DEBUG options spread around the place. If you enable
one and not another you can end up with an emulator that does not work,
since each file can have a different view of what the registers look like.
To fix this, create a global CONFIG_X86EMU_DEBUG option that keeps
everything consistent.

ad6edca379 bios_emulator: Allow x86 to use the emulator
There is an implicit assumption that x86 machines want to use raw I/O in the
BIOS emulator, but this should be selectable. Add an CONFIG_X86EMU_RAW_IO
option to control it instead.

Also fix a few bugs which cause warnings on x86 and adjust the Makefile to
remove the assumption that only PowerPC uses the emulator.

472d546054 Consolidate bool type
'bool' is defined in random places. This patch consolidates them into a
single header file include/linux/types.h, using stdbool.h introduced in C99.

All other #define, typedef and enum are removed. They are all consistent with
true = 1, false = 0.

Replace FALSE, False with false. Replace TRUE, True with true.
Skip *.py, *.php, lib/* files.
