Move variables to point of first use, reducing their scope.
Add driver_name temporary to help arguments be changed later.
Eliminates the useless 'found' variable, changing the code to terminate
the loop immediate and return its success.
After adding support for referencing banks by name, renames
the COMMAND_HELPERs appropriately:
flash_command_get_bank_by_num -> flash_command_get_bank
nand_command_get_device_by_num -> flash_command_get_device
Add get_flash_bank_by_name (and get_nand_device_by_name) helpers
to retrieves struct flash_bank * (struct nand_device *) given a
driver name and an (optional) driver-specific bank index.
These are used to extend flash_command_get_bank_by_num (and
nand_command_get_device_by_num) to allow all flash (nand) commands to
reference defined banks by name, not just by number.
To avoid some code duplication, add the flash/common.[ch] files to hold
functionality common to both types driver. The first two methods are
helpers for the above routines to find a bank specified by a "name" or
"name.index" string. get_flash_name_index() finds the '.index' portion,
while flash_driver_name_matches() performs the string portion matching.
Use size_t instead of uint32_t when specifying file sizes. Update all
consumers up through the layers to use size_t when required. These
changes should be safe, but the higher-levels will need to be updated
further to receive the intended benefits (i.e. large file support).
Add error checking for fileio_read and file_write. Previously, all
errors were being silently ignored, so this change might cause some
problems for some people in some cases. However, it gives us the chance
to handle any errors that do occur at higher-levels, rather than burying
our heads in the sand.
By using CALL_COMMAND_HANDLER, parameters can be reordered, added, or
even removed in inherited signatures, without requiring revisiting
all of the various call sites.
Add 'const' keyword to 'char *' parameters to allow command handlers to
pass constant string arguments. These changes allow the 'args' command
handler to be changed to 'const' in a subsequent patch.
Remove useless forward declarations.
Moves command registration to end of file.
Moves flash structure definition to end of file.

This patch changes the duration_* API in several ways. First, it
updates the API to use better names. Second, string formatting has
been removed from the API (with its associated malloc). Finally, a
new function added to convert the time into seconds, which can be
used (or formatted) by the caller. This eliminates hidden calls to
malloc that require associated calls to free().
This patch also removes the useless extern keyword from prototypes,
and it eliminates the duration_t typedef (use 'struct duration').
These API also allows proper error checking, as it is possible for
gettimeofday to fail in certain circumstances.
The consumers have all been chased to use this new API as well, as
there were relatively few cases doing this type of measurement.
In most cases, the code performs additional checks for errors, but
the calling code looks much cleaner in every case.
This eliminates redundant code for parsing and retreiving the bank
specified from a script command argument. This patch was written to
replace existing functionality; however, the parsing logic can be
updated later to allow flash commands to accept bank names as well as
their numbers.
of a (NOR) flash chip: allow passing "last" as an alias
for the number of the last sector.
Improve several aspects of error checking while we're at it.

Also minor fixes for the message from "fill": the byte
count is unsigned, not signed; and more importantly,
print the real number of bytes written
