This commit introduces new config: CONFIG_SYS_MALLOC_CLEAR_ON_INIT.
This config is an expert option and is enabled by default.
The all amount of memory reserved for the malloc, is by default set
to zero in mem_malloc_init(). When the malloc reserved memory exceeds
few MiB, then the boot process can slow down.
So disabling this config, is an expert option to reduce the boot time,
and can be disabled by Kconfig.
Note:
After disable this option, only calloc() will return the pointer
to the zeroed memory area. Previously, without this option,
the memory pointed to untouched malloc memory region, was filled
with zeros. So it means, that code with malloc() calls should
be reexamined.

For writing files, DFU implementation requires the file buffer
with the len at least of file size. For big files it requires
the same big buffer.
Previously the file buffer was allocated as a static variable,
so it was a part of U-Boot .bss section. For 32MiB len of buffer
we have 32MiB of additional space, required for this section.
The .bss needs to be cleared after the relocation.
This introduces an additional boot delay at every start, but usually
the dfu feature is not required at the standard boot, so the buffer
should be allocated only if required.
This patch removes the static allocation of this buffer,
and alloc it with memalign after first call of function:
- dfu_fill_entity_mmc()
and the buffer is freed on dfu_free_entity() call.
This was tested on Trats2.

For ARM architecture, enable the CONFIG_USE_ARCH_MEMSET/MEMCPY,
will highly increase the memset/memcpy performance. This is able
thanks to the ARM multiple register instructions.
Unfortunatelly the relocation is done without the cache enabled,
so it takes some time, but zeroing the BSS memory takes much more
longer, especially for the configs with big static buffers.
A quick test confirms, that the boot time improvement after using
the arch memcpy for relocation has no significant meaning.
The same test confirms that enable the memset for zeroing BSS,
reduces the boot time.
So this patch enables the arch memset for zeroing the BSS after
the relocation process. For ARM boards, this can be enabled
in board configs by defining: 'CONFIG_USE_ARCH_MEMSET'.
This was tested on Trats2.

The 'nandecc sw' command selects a software-based error correction
algorithm. By default, this is OMAP_ECC_HAM1_CODE_SW but some
platforms use OMAP_ECC_BCH8_CODE_HW_DETECTION_SW as their
software-based correction algorithm. Allow a user to be specific e.g.
# nandecc sw <hamming|bch8>
where 'hamming' is still the default.
Note: we don't just use CONFIG_NAND_OMAP_ECCSCHEME as it might be set
to a hardware-based ECC scheme---a little strange when the user
has requested 'sw' ECC.

Commit fb384c4720 introduced the use of
WAIT0 pin for determining whether the NAND is ready or not. This only
works if all NAND chips are connected to WAIT0. If some chips are
connected to the other available pin WAIT1, nand_wait() does not really
wait and prints a WARN_ON message.
This patch allows the board to provide configuration of which chip is
connected to which WAITx signal. For example, one can define in
include/configs/foo.h:
#define CONFIG_NAND_OMAP_GPMC_WSCFG 0,0,1,1
This would mean that chips using to CS0 and 1 are connected to WAIT0 and
chips with CS2 and 3 are connected to WAIT1.
