[PATCH] split spi.c and fix include headers
by Sean Nelson 25 Feb '10

25 Feb '10

Split spi.c into programmer and chip drivers. Make it so flash.h doesn't include any other flashrom-related headers. Fix includes in files. Signed-off-by: Sean Nelson <audiohacked(a)gmail.com> --- Made as minimal changes as I could, and split sli.c where it was clearly programmer code where the rest was moved to spi25.c. Names and Ideas as suggested by carldani.

p4b533-e flashrom fail bosss@irc not urgent anymore, flashed with uniflash
by gdocs123 123 25 Feb '10

25 Feb '10

I got the "other firmware p4p800se-deluxe" flashed succesfully using the socket from p4b533e motherboard by using the uniflash2.05b tool on a dos startup floppy made in windows xp. Maybe in 'distant' future I can try flashing with a newer version of flashrom if I want to take risks... like maybe try a beta bios etc... but for a couple of weeks / months I keep it this way. Here is some output info for my board asked on IRC, I hope it will help you with the development of flashrom. Thanks for the support and input sofar. If you like I can also sent you output info of p4p800s-e "deluxe" which is fixed btw. grtz Walter

Request for ideas: Asus as99127f sensor chip on I2C protects flash!
by Michael Karcher 24 Feb '10

24 Feb '10

Hello flashrom people, I have a confirmed report now that unlocking of some Asus boards (most likely many Asus boards with the VIA VT82C686 south bridge "Apollo Super South") needs i2c communication with the custom hardware sensor interface chip named as99127f, which is a derivate of the winbond w83782d, which is supported by the w83781d module. Contrary to the Winbond chip, the Asus chip is *only* reachable via I2C, connected to the I2C port of the south bridge, no ISA interface. And it has a register at I2C address 0x80 in bank one (accessed using the first subdevice) that contains a flash write protect bit. The original w83782d has no register addresses above 0x7f. Here some logs from an Asus A7V133 board: State after reboot: Parallel flash accepts no write cycles http://coreboot.pastebin.com/m2801f3ff Using i2cget (from i2c-tools), after loading i2c-dev module and unloading w83781d (to prevent contention) http://coreboot.pastebin.com/f1255a2cc Flash protect is bit 3, so clearing this bit and running flashrom again makes the chip visible: http://coreboot.pastebin.com/f35e34cf3 How do we approach these boards? 1) Direct port access of the i2c bus in the south bridge: is a bad idea, as it might conflict with the i2c driver from the OS. 2) OS specific general i2c access: Probably working, but might interfere with hardware monitor drivers that try to access the same chip. i2c support has to be added for each OS. 3) Chip-specific driver for enabling flashing: In Linux this means adding a "flash_protect" sysfs property in the w83781d driver if the Asus chip is detect. Definitely the most clean way on linux, but needs a kernel patch, which OTOH should be easy to get into new kernels, but still makes them a prerequisite of running flashrom on these boards. No idea about non-Linux systems. Regards, Michael Karcher
