c9689ca318 Add a way of checking the position of a structure member
U-Boot uses structures for hardware access so it is important that these
structures are correct. Add a way of asserting that a structure member is
at a particular offset. This can be created using the datasheet for the
hardware.

This implementation uses Static_assert() since BUILD_BUG_ON() only works
within functions.

ea11b401b5 meminfo cmd: Enable printing >=4GiB SDRAM sizes
gd->ram_size is stored as phys_size_t type which can be bigger than an
unsigned long on some architectures.  When using unsigned long type,
SDRAM of 4GiB or larger will not print the correct size, but using
phys_size_t will.

d87a2ad108 powerpc/mpc85xx: Remove some dead code
U-Boot does not have system calls (the services it exposes to
standalone commands use a different mechanism), so the syscall handler
is dead code.  It's also broken code, as it assumes it is located at
0xc00 -- while even before the patch to stop relocating exception
vectors to 0, U-Boot had the syscall at 0x900.

The critical and machine check return paths are never called -- the
regular exception return path is used instead, which works because
xSRR0/1 have already been saved and can be restored via the regular
SRR0/1 (we don't care too much in U-Boot about taking a critical/mcheck
inside another exception prolog/epilog).

Also remove a few other small unused functions.

b8bf0adc12 powerpc/mpc85xx: Add DSP side awareness for Freescale Heterogeneous SoCs
The code provides framework for heterogeneous multicore chips based on StarCore
and Power Architecture which are chasis-2 compliant, like B4860 and B4420

It will make u-boot recognize all non-ppc cores and peripherals like
SC3900/DSP CPUs, MAPLE, CPRI and print their configuration in u-boot logs.
Example boot logs of B4860QDS:

0365ffcc0b generic-board: show model name in board_init_f() too
The common/board_r.c has show_model_r() to display the model name
if the DTB has a "model" property.  It sounds useful to have a similar
function in common/board_f.c too because most of the boards show
their board name before relocation.

Instead of implementing the same function in both common/board_f.c
and common/board_r.c, let's split it up into common/show_board_info.c.

(Please do not add arch-specific stuff to include/common.h any more;

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.

709ea543b9 stdio: Pass device pointer to stdio methods
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.

d718ded056 lib: uuid: code refactor for proper maintain between uuid bin and string
Changes in lib/uuid.c to:
- uuid_str_to_bin()
- uuid_bin_to_str()

New parameter is added to specify input/output string format in listed functions
This change allows easy recognize which UUID type is or should be stored in given
string array. Binary data of UUID and GUID is always stored in big endian, only
string representations are different as follows.

String byte: 0                                  36
String char: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
string UUID:    be     be   be   be       be
string GUID:    le     le   le   be       be

This patch also updates functions calls and declarations in a whole code.

a96a0e6153 part_efi: move uuid<->string conversion functions into lib/uuid.c
This commit introduces cleanup for uuid library.
Changes:
- move uuid<->string conversion functions into lib/uuid.c so they can be
  used by code outside part_efi.c.
- rename uuid_string() to uuid_bin_to_str() for consistency with existing
  uuid_str_to_bin()
- add an error return code to uuid_str_to_bin()
- update existing code to the new library functions.
