d85879938d dm: implement a MTD uclass
Implement a Memory Technology Device (MTD) uclass. It should
include most flash drivers in the future. Though no uclass ops
are defined yet, the MTD ops could be used.

The NAND flash driver is based on MTD. The CFI flash and SPI
flash support MTD, too. It should make sense to convert them
to MTD uclass.

8be60f06c2 linux/kconfig.h: add CPP macros useful for per-image config options
The previous commit introduced a useful macro used in makefiles,
in order to reference to different variables (CONFIG_... or
CONFIG_SPL_...) depending on the build context.

Per-image config option control is a PITA in C sources, too.
Here are some macros useful in C/CPP expressions.

CONFIG_IS_ENABLED(FOO) can be used as a shorthand for

  (!defined(CONFIG_SPL_BUILD) && defined(CONFIG_FOO)) || \
   (defined(CONFIG_SPL_BUILD) && defined(CONFIG_SPL_FOO))

For example, it is useful to describe C code as follows,

  #if CONFIG_IS_ENABLED(OF_CONTROL)
      (device tree code)
  #else
      (board file code)
  #endif

The ifdef conditional above is switched by CONFIG_OF_CONTROL during
the U-Boot proper building (CONFIG_SPL_BUILD is not defined), and by
CONFIG_SPL_OF_CONTROL during SPL building (CONFIG_SPL_BUILD is
defined).

The macro can be used in C context as well, so you can also write the
equivalent code as follows:

  if (CONFIG_IS_ENABLED(OF_CONTROL)) {
      (device tree code)
  } else {
      (board file code)
  }

Another useful macro is CONFIG_VALUE().
CONFIG_VALUE(FOO) is expanded into CONFIG_FOO if CONFIG_SPL_BUILD is
undefined, and into CONFIG_SPL_FOO if CONFIG_SPL_BUILD is defined.

You can write as follows:

  text_base = CONFIG_VALUE(TEXT_BASE);

instead of:

  #ifdef CONFIG_SPL_BUILD
      text_base = CONFIG_SPL_TEXT_BASE;
  #else
      text_base = CONFIG_TEXT_BASE;
  #endif

This commit also adds slight hacking on fixdep so that it can
output a correct list of fixed dependencies.

If the fixdep finds CONFIG_IS_ENABLED(FOO) in a source file,
we want
    $(wildcard include/config/foo.h)
in the U-boot proper building context, while we want
    $(wildcard include/config/spl/foo.h)
in the SPL build context.

6b9f9eadff linux_compat: handle __GFP_ZERO in kmalloc()
Currently, kzalloc() returns zero-filled memory, while kmalloc()
simply ignores the second argument and never fills the memory
area with zeros.

I want kmalloc(size, __GFP_ZERO) to behave as kzalloc() does,
which will make it easier to add more memory allocator variants.

With the introduction of __GFP_ZERO flag, going forward, kzmalloc()
variants can fall back to kmalloc() enabling the __GFP_ZERO flag.

3721eaf28e linux_compat: remove cpu_relax() define
The macro cpu_relax() is defined by several headers in different
ways.

arch/{arm,avr32,mips}/include/asm/processor.h defines it as follows:
  #define cpu_relax()	barrier()

On the other hand, include/linux/compat.h defines it as follows:
  #define cpu_relax() do {} while (0)

If both headers are included from the same source file, the warning
  warning: "cpu_relax" redefined [enabled by default]
is displayed.

It effectively makes it impossible to include <linux/compat.h>
from some sources.  Drop the latter.

f18d11163e mtd: fix false positive "Offset exceeds device limit" error
Since commit 09c3280754 (mtd, nand: Move common functions from
cmd_nand.c to common place), NAND commands would not work at all
on large devices.

    => nand read 80000000 10000 10000

    NAND read: Offset exceeds device limit
    => nand erase 100000 100000

    NAND erase: Offset exceeds device limit

The type of the "size" of "struct mtd_info" is uint64_t, while
mtd_arg_off_size() and mtd_arg_off() treat chipsize as int type.
The chipsize is wrapped around if the argument is given with 2GB
or larger.

c316f577b4 mtd: OMAP: Enable GPMC prefetch mode
Enable GPMC's prefetch feature for NAND access. This speeds up NAND read
access a lot by pre-fetching contents in the background and reading them
through the FIFO address.

The current implementation has two limitations:

 a) it only works in 8-bit mode
 b) it only supports read access

Both is easily fixable by someone who has hardware to implement it.

Note that U-Boot code uses non word-aligned buffers to read data into, and
request read lengths that are not multiples of 4, so both partial buffers
(head and tail) have to be addressed.

Tested on AM335x hardware.

e6126a5872 x86: move arch-specific asmlinkage to <asm/linkage.h>
Commit 65dd74a674 (x86: ivybridge: Implement SDRAM init) introduced
x86-specific asmlinkage into arch/x86/include/asm/config.h.

Commit ed0a2fbf14 (x86: Add a definition of asmlinkage) added the
same macro define again, this time, into include/common.h.
(Please do not add arch-specific stuff to include/common.h any more;
it is already too cluttered.)

The generic asmlinkage is defined in <linux/linkage.h>.  If you want
to override it with an arch-specific one, the best way is to add it
to <asm/linkage.h> like Linux Kernel.

80d9ef8d40 lib: string: move strlcpy() to a common place
Move strlcpy() definition from drivers/usb/gadget/ether.c to
lib/string.c because it is a very useful function.
Let's add the prototype to include/linux/string.h too.

just add a few ifdefs around because this
device is very similar to dra7xxx.
