We use FIFOs on some devices, so flush them before exiting so
we do not get funny characters in the output.

The alternative memory test implementation needs a scratch
memory location to remove the last data from the data bus.
Instead of using a NULL pointer for this, default to the
memory start address.
No sane program should consider a NULL pointer as a safe default.

Introduce config definitions similar to that
defined in Linux MTD layer. These allow us to
enable conditional features.

When reading from bad block aware devices we must make sure not
to read beyond eraseblock boundaries.

The default download device was /dev/mem
Quote Sascha:
"This is a quite dangerous thing. There are
quite some boards out there which have NOR
Flash on 0x0. With a default file of
/dev/mem we would overwrite U-Boot."
Change default device to image.bin

Default loadb behavior works on packet sized
chunks of kermit data to be put on target file
This would not work good on block devices such
as NAND. solution will be to buffer data up to
standard 4096 chunks before giving to device.

-d represents devices only.. but loadb can
operate on files as well. hence Use -f as
option to select the output file. This is
more representative of what we are trying
to do.

Allow loadb and loady to create file if file not
present. This will allow for downloading a file
to filesystem and cp or doing other operations on
the same. Making this as an option instead of a
default behavior ensures that users intend to
create file when they use -c option

Add an own device id for partitions. This is necessary to allow
the partition layer to check if the given device is really a partition.
Also, check for readonly flag in erase.

Close the file in saveenv before calling envfs_save and reopen it
afterwards. NAND Bad block aware devices allow opening a file only
once.

[Patch 08/17] U-Boot-V2:Commands Unbreak loadb support
This patch provides support for loadb and loady and enables the broken feature

Memory layout can now be specified via kconfig options. Two
possibilities exist: default layout means the layout is stack
/ malloc heap / U-Boot. The user can also specify fixed addresses
for each TEXT_BASE / stack / malloc heap.
For practical reasons I changed all string literals assumed to be constant
to reside in .rodata subsection at end of .text section.
