tools: imls: Remove a broken and unused tool.
It looks like tools/imls/Makefile is invoked from nowhere. And also it is broken. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

IMLS
|
||||
-------------
|
||||
|
||||
imls is an implementation of a Linux command line tool to access
|
||||
to raw flash partitions and list images made with mkimage command.
|
||||
|
||||
For building against older versions of the MTD headers (meaning before
|
||||
v2.6.8-rc1) it is required to pass the argument "MTD_VERSION=old" to
|
||||
make.
|
||||
|
||||
Usage examples
|
||||
--------------
|
||||
|
||||
1) Flash with sectors of 128KiB and 32 sectors:
|
||||
|
||||
> imls -c 32 -s 131072 /dev/mtd0
|
||||
Searching...
|
||||
Image Name: foo
|
||||
Created: Fri Apr 10 18:11:30 2009
|
||||
Image Type: Intel x86 Linux Standalone Program (uncompressed)
|
||||
Data Size: 10716 Bytes = 10.46 kB = 0.01 MB
|
||||
Load Address: 00000000
|
||||
Entry Point: 00000000
|
||||
|
||||
2) Flash with sectors of 64KiB and 128 sectors and with a search offset of one
|
||||
sector:
|
||||
|
||||
> imls -o 1 -c 128 -s 65536 /dev/mtd0
|
||||
Searching...
|
||||
Image Name: foo
|
||||
Created: Fri Apr 10 18:11:30 2009
|
||||
Image Type: Intel x86 Linux Standalone Program (uncompressed)
|
||||
Data Size: 10716 Bytes = 10.46 kB = 0.01 MB
|
||||
Load Address: 00000000
|
||||
Entry Point: 00000000
