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>master

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 |
