* ihex: fix unused return value compiler warningChris Ruffin2011-01-131-4/+5

* ihex: add support for CS:IP/EIP recordsMark Brown2010-10-261-3/+14
| | | | | | | | | | | | | | | | | | ihex firmwares can include a jump address for starting execution. Add a -j option which will cause this to be written into the generated file as a record with address zero and data consisting of the address to jump to, allowing drivers to make use of this information. This format is chosen because it most closely follows the original ihex format, though it may make more sense to write a record with length zero and the address stored as the address. The records are not omitted by default since our ihex format does not include record type information and so including additional records may lead to confusion.

* Revert "fix modules_install via NFS"David Woodhouse2009-04-061-0/+268
| | | | | | | | | | This reverts commit 8b249b6856f16f09b0e5b79ce5f4d435e439b9d6. This 'fix' is not necessary; we just need to undo the damage caused accidentally by Igor/Mauro in 4b29631db33292d416dc395c56122ea865e7635c ("V4L/DVB (9533): cx88: Add support for TurboSight TBS8910 DVB-S PCI card") Signed-off-by: David Woodhouse <>
* fix modules_install via NFSSam Ravnborg2009-01-071-268/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rafael reported: I get the following error from 'make modules_install' on my test boxes: HOSTCC firmware/ihex2fw /home/rafael/src/linux-2.6/firmware/ihex2fw.c:268: fatal error: opening dependency file firmware/.ihex2fw.d: Read-only file system compilation terminated. make[3]: *** [firmware/ihex2fw] Error 1 make[2]: *** [_modinst_post] Error 2 make[1]: *** [sub-make] Error 2 make: *** [all] Error 2 where the configuration is that the kernel is compiled on a build box with 'make O=<destdir> -j5' and then <destdir> is mounted over NFS read-only by each test box (full path to this directory is the same on the build box and on the test boxes). Then, I cd into <destdir>, run 'make modules_install' and get the error above. The issue turns out to be that we when we install firmware pick up the list of firmware blobs from firmware/Makefile. And this triggers the Makefile rules to update ihex2fw. There were two solutions for this issue: 1) Move the list of firmware blobs to a separate file 2) Avoid ihex2fw rebuild by moving it to scripts As I seriously beleive that the list of firmware blobs should be done in a fundamental different way solution 2) was selected.

* Fix IHEX firmware generation/loadingMarc Zyngier2008-08-021-3/+3
| | | | | | | | | Fix both the IHEX firmware generation (len field always null, and EOF marker a byte too short) and loading (struct ihex_binrec needs to be packed to reflect the on-disk structure). Signed-off-by: Marc Zyngier <> Signed-off-by: David Woodhouse <>
* ihex: Add support for long records to ihex2fw.cDavid Woodhouse2008-07-101-19/+40
| | | | | | | | | | | | | | Some drivers could do with using records like Intel HEX, but with each record being larger than 256 bytes. This has been possible in the binary representation (struct ihex_binrec) in the kernel since the beginning -- at least of the the current version of history. But we haven't been able to represent that in the .HEX files which get converted to .fw files. This adds a '-w' option to ihex2fw to make it interpret the first _two_ bytes of each line as the record length, instead of only one byte. And adds makefile rules for %.H16->%.fw which use that.

* ihex: add ihex2fw tool for converting HEX files into firmware imagesDavid Woodhouse2008-07-101-0/+247
Not the straight conversion to binary which objcopy can do for us, but actually representing each record with its original {addr, length}, because some drivers need that information preserved. Fix up 'firmware_install' to be able to build $(hostprogs-y) too. Signed-off-by: David Woodhouse <>
