#9 support for AMD AM29LV160DB flash needed

[Oleg]

I have successfully read flash by Brecis (PMC-Sierra)
MSP2006 processor (used in Gigabyte GN-B49G router),
but can not flash, because there is no support in
libbrux/flash/amd.c for AM29LV160DB (used widely
nowdays
http://calradio.calit2.net/calradio1/dspboard/datasheet
s/AM29LV160DB.pdf

Give me a direction how to implement support for this
flash chips.

i have found patch for 0.5.1 wich add support for this chip
http://pages.sbcglobal.net/greghol/routers/jtag051-29lv160-
patch.tar.bz2 , but it was not included in CVS. Futhermore
there is some mutual changes in flash.c with
http://cvs.sourceforge.net/viewcvs.py/openwince/jtag/src/fla
sh.c?r1=1.29&r2=1.30 wich must be cleaned.

Hello Olegi,
This is a patch I made to support the AMD part in 16 bit
mode for to be used for the Samsung 4510B ARM7 boards I
have. While the changes I made works for me I didnt submit
it back to the patch area becasue I may have broken other
areas. The 29LV160 patch was made based on the jtag-0.5.1
base code after the Samsung S3C4510B Bus patch was done.
Feel free to finish it up. Greg
