/proc/mtd doesn't contain the mtd-id of the device, but the part name from the
command line. This corrects what I believe is an obsolete comment from commit

The mtd documentation makes no mention of the useful feature whereby
partitions' logical ordering need not match their physical ordering.
Truncation of parts, skipping of zero sized parts, and handling of
overlapping parts are similarly not mentioned.This updates the comments at the top of file describing the command
line parsing as currently implemented. I proposed this in

When the kernel parses the following cmdline
#mtdparts=gpmi-nand:16m(boot),16m(kernel),1g(home),4g(test),-(usr)
for a big nand chip Micron MT29F64G08AFAAAWP(8GB), we got the following wrong
result:.............................................
"mtd: partition size too small (0)"
.............................................We can not get any partition.
The "4g(test)" partition triggers a overflow of the "size". The memparse()
returns 4g to the "size", but the size is "unsigned long" type, so a overflow
occurs, the "size" becomes zero in the end.This patch changes the "size"/"offset" to "unsigned long long" type,
and replaces the UINT_MAX with ULLONG_MAX for macros SIZE_REMAINING and
OFFSET_CONTINUOUS.Signed-off-by: Huang Shijie

Simply 'parse_cmdline_partitions': the outer loop iterating over
'partitions' is actually a search loop, it does not execute the inner
loop for each partition, only for the matched partition.Let's break when search is successful, and move all inner code (relevant
only for the matched partition) outside of the outer loop.Resulting code is much more readable, and makes the indent level sane.

Huang Shijie explains:
Assume we have a 1GiB(8Gib) NAND chip, and we set the partitions
in the command line like this:
#gpmi-nand:100m(boot),100m(kernel),1g(rootfs)In this case, the partition truncating occurs. The current code will
get the following result:----------------------------------
root@freescale ~$ cat /proc/mtd
dev: size erasesize name
mtd0: 06400000 00040000 "boot"
mtd1: 06400000 00040000 "kernel"
----------------------------------It is obvious that we lost the truncated partition `rootfs` which should
be 824MiB in this case.Also, forbid 0-sized partitions.

Clean-up the driver a bit to make it easier to read and amend the coding style.

This patch revises and fixes error handling in the command line mtd
partitions parser. Namely:
1. we ignored return code of 'mtdpart_setup_real()'.
2. instead of returning 0 for failure and 1 for success, teach
'mtdpart_setup_real()' to return real error codes.Signed-off-by: Artem Bityutskiy

Patch for unlocking all Intel flash that has instant locking on power up.
The patch has been tested on Intel M18, P30 and J3D Strata Flash.
1. The automatic unlocking can be disabled for a particular partition
in the map or the command line.
a. For the bit mask in the map it should look like:
.mask_flags = MTD_POWERUP_LOCK,
b. For the command line parsing it should look like:
mtdparts=0x80000(bootloader)lk
2. This will only unlock parts with instant individual block locking.
Intel parts with legacy unlocking will not be unlocked.Signed-off-by: Justin Treon
