Support for Intel DH89xxCC PCH

[Sean Mahood]

Hello,

I have confirmed that the the following addition to chipset_enable.c  
will allow the programming of DH89xxCC PCH chips.

{0x8086, 0x1d40, OK, "Intel", "X79",        enable_flash_pch6},
     {0x8086, 0x1d41, NT, "Intel", "X79",        enable_flash_pch6},
+   {0x8086, 0x2310, NT, "Intel", "DH89xxCC",   enable_flash_pch6},
     {0x8086, 0x2410, OK, "Intel", "ICH",        enable_flash_ich_4e},
     {0x8086, 0x2420, OK, "Intel", "ICH0",       enable_flash_ich_4e},

Similar patches have been made to operating systems:

Linux

FreeBSD
http://lists.freebsd.org/pipermail/svn-src-head/2011-January/024584.html

I am not sure of the process in which to get this added to the next  
release, so I thought it wise to post it here.

Hope this helps!

Sincerely,
Sean Mahood

If programming (write/erase) on that DH89xxCC chipset is confirmed to
work, you should change NT to OK.

Can you download the latest code [1], edit chipset_enable.c and submit
and sign-off a patch - see [2]?
