11955590a2 dts: renamed FIT_EMBED to MULTI_DTB_FIT and moved it to the dts Kconfig
CONFIG_FIT_EMBED might be confused with CONFIG_OF_EMBED, rename it
MULTI_DTB_FIT as it is able to get a DTB from a FIT image containing
multiple DTBs. Also move the option to the Kconfig dedicated to the DTS
options and create a README for this feature.

3ea0520512 disk: part_dos: Use the original allocation scheme for the SPL case
Since commit ff98cb9051 ("part: extract MBR signature from partitions")
SPL boot on i.MX6 starts to fail:

U-Boot SPL 2017.09-00221-g0d6ab32 (Oct 02 2017 - 15:13:19)
Trying to boot from MMC1
(keep in loop)

Use the original allocation scheme for the SPL case, so that MX6 boards
can boot again.

This is a temporary solution to avoid the boot regression.

6a3e65dea3 common: Drop LOGLEVEL to 4
While this came in with a default value of 6 I am lowering this to 4.
The MTD/UBI code has a large number of error messages that we include
now.  In addition, "normally" warning messages are not included so this
feels like a more natural level to have.

ceb9190969 dm: replace dm_dbg() with pr_debug()
As we discussed before in ML, dm_dbg() causes undefined reference
error if #define DEBUG is added to users, but not drivers/core/util.c

We do not need this macro because we can use pr_debug() instead, and
it is pretty easy to enable it for the DM core by using ccflags-y.

c898cba41e dm: define dev_*() log functions in DM header
Many drivers had started to use dev_err, dev_info, etc. for log
functions.  Currently, we are relying on <linux/compat.h>, but I
guess the best home is <dm/device.h>, taking into account that
Linux defines them in <linux/device.h>.

For now, I am leaving the ones in <linux/compat.h> because lots of
Linux-originated code uses dev_*(), but the first argument is not
struct udevice, so we need to ignore the bogus argument.  More
efforts are needed to iron out the issues.

059a48096c bug.h: sync BUILD_BUG stuff with Linux 4.13
As commit 84b8bf6d5d ("bug.h: move BUILD_BUG_* defines to
include/linux/bug.h") noted, include/linux/bug.h was locally
modified for U-Boot because the name conflict of error() caused
build errors at that time.

Now error() is gone, so we can fully sync BUILD_BUG* with Linux.
These macros are just compile-time utilities.  Nothing depends on
platform code, so it should make sense to simply copy Linux's ones.

Please note Linux split BUILD_BUG stuff out into <linux/build_bug.h>
by commit bc6245e5efd7.  Let's follow it.

9b643e312d treewide: replace with error() with pr_err()
U-Boot widely uses error() as a bit noisier variant of printf().

This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:

  # define __compiletime_error(message) __attribute__((error(message)))

This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux.  (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)

Let's convert error() into now treewide-available pr_err().

Done with the help of Coccinelle, excluing tools/ directory.

The semantic patch I used is as follows:

// <smpl>
@@@@
-error
+pr_err
 (...)
// </smpl>

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.

Instead of adding more and more special cases as the number of SoCs grow,
let's invert the test to have 0x410 by default, and the (hopefully) fixed
number of old SoCs being the exception.

de86fc3859 sunxi: Remove the MMC index hack
The current code, if there's both an eMMC and an MMC slot available on the
board, will swap the MMC indices based on whether we booted from the eMMC
or the MMC. This way, the MMC we're supposed to boot on will always have
the index 0.

However, this causes various issues, for example when using other
components that base their behaviour on the MMC index, such as fastboot.

Let's remove that hack, and take the opposite approach. The MMC will always
have the same index, but the bootcmd will pick the same device than the one
we booted from. This is done through the introduction of the mmc_bootdev
environment variable that will be filled by the board code based on the
boot device informations we can get from the SoC.

In order to not introduce regressions, we also need to adjust the fastboot
MMC device and the environment device in order to set it to the eMMC, over
the MMC, like it used to be the case.

e16986c481 nios2: Use asm-generic/io.h
Convert the nios2 architecture to make use of the new asm-generic/io.h to
provide address mapping functions. As nios2 actually performs
non-identity mapping between physical & virtual addresses we can't
simply make use of the generic functions, with the exception of being
able to drop our no-op unmap_physmem() and definitions of unused map
flags.

Feedback from architecture maintainers is welcome.

e8645527b1 xtensa: Use asm-generic/io.h
Convert the xtensa architecture to make use of the new asm-generic/io.h
to provide address mapping functions. As the generic implementations are
suitable for xtensa this is primarily a matter of moving code.

This has only been build-tested, feedback from architecture maintainers
is welcome.
