History

Scott Wood d984fed068 makefiles: fixes for building build tools Currently, some of the tools instead set CC to be HOSTCC in order to re-use some pattern rules -- but this fails when the user overrides CC on the make command line. Also, the HOSTCFLAGS in tools/Makefile are currently not being used because config.mk overwrites them. This patch adds static pattern rules for files that have been requested to be built with the native compiler using $(HOSTSRCS) and $(HOSTOBJS), and converts the tools to use them. It restores easylogo to using the host compiler, which was broken by commit `38d299c2db` (if this was an intentional change, please let me know -- but it seems to be a build tool). It restores -pedantic and the special flags for darwin and cygwin that were requested in tools/makefile (but keeps the flags added by config.mk) -- hopefully someone can test this on those platforms. It no longer conditionalizes -pedantic on not being darwin; it wasn't clear that that was intentional, and unless there's a real problem it's just inviting people to contribute non-pedantic patches to those files (I'm not a fan of -pedantic personally, but if it's on for one platform it should be on for all). HOST_LDFLAGS is renamed HOSTLDFLAGS for consistency with the previous HOST_CFLAGS to HOSTCFLAGS rename. A new HOSTCFLAGS_NOPED is made available for those files which currently cannot be built with -pedantic, and replaces the old FIT_CFLAGS. imls now uses the cross compiler properly, rather than by trying to reconstruct CC using the typoed $(CROSS_COMPILER). envcrc.c is now dependency-processed unconditionally -- previously it would be built without being on (HOST)SRCS if CONFIG_ENV_IS_EMBEDDED was not selected.

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
