fb5cf7f16b Move initf_malloc() to a common place
To allow this function to be used from SPL, move it to the malloc()
code.

c9356be307 dm: Split the simple malloc() implementation into its own file
The simple malloc() implementation is used when memory is tight. It provides
a simple buffer with an incrementing pointer.

At present the implementation is inside dlmalloc. Move it into its own file
so that it is easier to find.

Rather than using relocation as a signal that the full malloc() is
available, add a special GD_FLG_FULL_MALLOC_INIT flag. This signals that the
simple malloc() should no longer be used.

In some cases, such as SPL, even the code space used by the full malloc() is
wasteful. Add a CONFIG_SYS_MALLOC_SIMPLE option to provide only the simple
malloc. In this case the full malloc is not available at all. It saves about
1KB of code space and about 0.5KB of data on Thumb 2.

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.

7b395232da malloc: make malloc_bin_reloc static
On architectures where manual relocation
is needed, the 'malloc_bin_reloc' function
must be called after 'mem_malloc_init'.

Make the 'malloc_bin_reloc' function static
and call it directly from 'mem_malloc_init'
instead of calling that from board_init_{r,f}
functions of the affected architectures.

00d0d2ad4e malloc: remove extern declarations of malloc_bin_reloc() in board.c files
Declare malloc_bin_reloc() in malloc.h and remove all extern declarations
in various board.c files to get rid of one checkpatch.pl warning.

21726a7afc Add assert() for debug assertions
assert() is like BUG_ON() but compiles to nothing unless DEBUG is defined.
This is useful when a condition is an error but a board reset is unlikely
to fix it, so it is better to soldier on in hope. Assertion failures should
be caught during development/test.

It turns out that assert() is defined separately in a few places in U-Boot
with various meanings. This patch cleans up some of these.

Build errors exposed by this change (and defining DEBUG) are also fixed in
this patch.
