If on your board is more than one flash, you must know
the size of every single flash, for example, for updating
the DTS before booting Linux. So make this function
flash_get_info() extern, and you can have all info
about your flashes.

include/flash.h was commented to say that the address in
flash_info->start was a physical address.  However, from u-boot's
point of view, and looking at most flash code, it makes more
sense for this to be a virtual address.  So I corrected the
comment to indicate that this was a virtual address.

The only flash driver that was actually treating the address
as physical was the mtd/cfi_flash driver.  However, this code
was using it inconsistently as it actually directly dereferenced
the "start" element, while it used map_physmem to get a
virtual address in other places.  I changed this driver so
that the code which initializes the info->start field calls
map_physmem to get a virtual address, eliminating the need for
further map_physmem calls.  The code is now consistent.

The *only* place a physical address should be used is when defining the
flash banks list that is used to initialize the flash_info struct,
usually found in the board config file.

Add cfi-mtd driver, which exports CFI flash to MTD layer.
This allows CFI flash devices to be used from MTD layer.

Building of the new driver is controlled by CONFIG_FLASH_CFI_MTD
option. Initialization is done by calling cfi_mtd_init() from
flash_init().

Add interface for flash verbosity control. It allows
to disable output from low-level flash API. It is useful
when calling these low-level functions from context other
than flash commands (for example the MTD/CFI interface
implmentation).

Export flash_sector_size() function from drivers/mtd/cfi_flash.c,
so that it can be used in the upcoming cfi-mtd driver.

The upcoming automatic update feature needs the ability to adjust an
address within Flash to the end of its respective sector. Factor out
this functionality to a new function flash_sect_roundb().

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).

Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

Fixes non-working CFI Flash on the Inka4x0 board.

The following patch adds support for non-CFI flash ROMS, by hooking into the
CFI flash code and using most of its code, as recently discussed here in the
thread "Mixing CFI and non-CFI flashs".
