uClinux Source Code Patch (Again) for Dual PC Modem

Dear Actiontec Dual PC Modem Hackers:

Oops!  The GPL source code update that I posted yesterday
accidentially used the wrong directory for source code
distribution.  Sorry about that...

It was also was missing a couple of key files.  It believe this
is right, but I have not had the time to start from scratch and
load the resultant firmware into one of my Actiontec modems.

The following *new* ZIP archive...

   http://www.lightner.net/ActionHack/DualPcModemGplPatch_1.2.zip

...contains a compressed TAR archive with the following files...

    linux/README_Actiontec.txt
    linux/.config
    linux/Makefile
    linux/arch/armnommu/mach-cx821xx/cnxtbsp.c
    linux/arch/armnommu/mach-cx821xx/cnxtflash.c
    linux/arch/armnommu/mach-cx821xx/cnxtflash.h
    linux/arch/armnommu/mach-cx821xx/cnxtirq.c
    linux/arch/armnommu/mach-cx821xx/gpioisr.c
    linux/arch/armnommu/mach-cx861xx/gpio.c
    linux/arch/armnommu/kernel/armksyms.c
    linux/include/linux/cnxtflash.h
    linux/include/asm-armnommu/arch-cx821xx/gpio.h
    linux/drivers/mtd/devices/mtdram.c

...which should end up overwriting files rooted at
"/opt/uClinux/linux/".

The text file "linux/README_Actiontec.txt" contains instructions.
The uClinux "config" file is "linux/.config".  I have used these
files with "make oldconfig" to build a stable Actiontec Dual PC
Modem uClinux kernel which runs correctly with Actiontec's "stock"
ROM file system.

The "Makefile" includes -DACTION_TEC as a global define:

   CPPFLAGS := -D__KERNEL__ -I$(HPATH) -DACTION_TEC

The other files are all GPL, and include the needed logic to work
with hardware that Actiontec *actually ships*.

I've updated the Wiki HOWTO page...

http://www.embeddedlinuxinterfacing.com/wiki.php/ActiontecGplReleaseHowto

...to include the following instructions:

INSTALLING THE LATEST ACTIONTEC GPL SOURCE RELEASE
--------------------------------------------------

  # su
  # wget -nd \
    ftp://128.121.226.214/pub/dualpcmodem/actiontec_release_031017.tar.gz
  # tar -zxvf actiontec_release_031017.tar.gz
  # usermod -G uClinux lightner
  # newgrp uClinux
  # cd Actiontec_Release/Actiontec_DPC_Base/
  # make

APPLYING PATCH TO /opt/uClinux/linux/
-------------------------------------

  # cd /opt/uCLinux
  # wget -nd http://www.lightner.net/ActionHack/DualPcModemGplPatch_1.2.zip
  # unzip DualPcModemGplPatch_1.2.zip
  # tar -zxf DualPcModemGplPatch_1.2.tar.gz

REBUILDING THE ACTIONTEC UCLINUX KERNEL
---------------------------------------

  % cd /opt/uClinux/linux/
  % newgrp uClinux
  % make clean
  % rm -f linux.bin linuz
  % make oldconfig
  % make dep
  % make linux.bin
  % gzip -c linux.bin > linuz

Please me know if this works any better!

Best regards,

Bruce
