37c9940a09 x86: use CONFIG_SYS_COREBOOT to descend into coreboot/ directory
The references of CONFIG_SYS_COREBOOT in arch/x86/cpu/coreboot/Makefile
are redundant because the build system descends into the directory
only when CONFIG_SYS_COREBOOT is defined.

165ecd26f0 kbuild: Descend into SOC directory from CPU directory
Some CPUs of some architectures have SOC directories.
At present, the build system directly descends into SOC directories
from the top Makefile, but it should generally descend into each
directory from its parent directory.

be25d875b9 Add pr_fmt() macro
This macro can be overridden in source files (before including common.h)
and can be used to specify a prefix for debug and error messages. An
example of how to use this is shown below:

	#define pr_fmt(fmt) "foo: " fmt

	#include <common.h>

	...
	debug("bar");

The resulting message will read:

	foo: bar

4efe52bf23 pci: Honour pci_skip_dev()
When enumerating devices, honour the pci_skip_dev() function. This can
be used by PCI controller drivers to restrict which devices will be
probed.

This is required by the NVIDIA Tegra PCIe controller driver, which will
fail with a data abort exception if an access is attempted to a device
number larger than 0 outside of bus 0. pci_skip_dev() is therefore
implemented to prevent any such accesses.

042b83d4c5 pci: Abort early if bus does not exist
When listing the devices on a PCI bus, the current code will blindly try
to access all devices. Internally this causes pci_bus_to_hose() to be
repeatedly called and output an error message every time. Prevent this
by calling pci_bus_to_hose() once and abort early if no bus was found.

1eebd14b79 vsprintf: Add modifier for phys_addr_t
Provide a new modifier to vsprintf() to print phys_addr_t variables to
avoid having to cast or #ifdef when printing them out. The %pa modifier
is used for this purpose, so phys_addr_t variables need to be passed by
reference, like so:

	phys_addr_t start = 0;

	printf("start: %pa\n", &start);

Depending on the size of phys_addr_t this will print out the address
with 8 or 16 hexadecimal digits following a 0x prefix.

59e890ef7b fs: make it possible to read the filesystem UUID
Some filesystems have a UUID stored in its superblock. To
allow using root=UUID=... for the kernel command line we
need a way to read-out the filesystem UUID.

changes rfc -> v1:
 - make the environment variable an option parameter. If not
   given, the UUID is printed out. If given, it is stored in the env
   variable.
 - corrected typos
 - return error codes

changes v1 -> v2:
 - fix return code of do_fs_uuid(..)
 - document do_fs_uuid(..)
 - implement fs_uuid_unsuported(..) be more consistent with the
   way other optional functionality works

changes v2 -> v3:
 - change ext4fs_uuid(..) to make use of #if .. #else .. #endif
   construct to get rid of unreachable code

18f26fdbd0 spl: Change debug to printf for "Unsupported boot-device"
We had the problem on an AM33xx platform, that SPL detected an
unsupported boot-device. But since this message is a debug message
it took a bit of time to really know, where the hangup in SPL
resulted from. So let's change this debug message to a printf
and also print the detected boot-device that is not supported.
This makes debugging of such cases much easier.

b41411954d linux/kernel.h: sync min, max, min3, max3 macros with Linux
U-Boot has never cared about the type when we get max/min of two
values, but Linux Kernel does.  This commit gets min, max, min3, max3
macros synced with the kernel introducing type checks.

Many of references of those macros must be fixed to suppress warnings.
We have two options:
 - Use min, max, min3, max3 only when the arguments have the same type
   (or add casts to the arguments)
 - Use min_t/max_t instead with the appropriate type for the first
   argument

cba1da495d include: move various macros to include/linux/kernel.h
U-Boot has imported various utility macros from Linux
scattering them to various places without consistency.

In include/common.h are min, max, min3, max3, ARRAY_SIZE, ALIGN,
container_of, DIV_ROUND_UP, etc.
In include/linux/compat.h are min_t, max_t, round_up, round_down,
etc.
We also have duplicated defines of min_t in some *.c files.

Moreover, we are suffering from too cluttered include/common.h.

This commit moves various macros that originate in
include/linux/kernel.h of Linux to their original position.

Note:
This commit simply moves the macros; the macros roundup,
min, max, min2, max3, ARRAY_SIZE are different
from those of Linux at this point.

4515992fc7 replace DIV_ROUND with DIV_ROUND_CLOSEST
The Linux-compatible macro DIV_ROUND_CLOSEST is a bit more flexible
and safer than DIV_ROUND.

For example,
  foo = DIV_ROUND_CLOSEST(x, y++)
works expectedly, but
  foo = DIV_ROUND(x, y++)
does not. (y is incremented twice.)

Otherwise the generic board init code in board_init_f (when
