SPI Controller ICH9 Flash driver
by Branham, Paul 06 Jul '11

06 Jul '11

Hello, We are using your open source flashrom driver for Intel PCH Ibex Peak. (SPI_Controller_ICH9 in the source code with generation>8 => ie. SPIBAR = 0x3800). The flash ROM driver works well using CS0 by design. What we are looking for is information on how to use the other chip select -CS1- for some other SPI device. All Intel documentation we have found for this SPI Controller only specifies how to use the Flash capabilities of CS0, but no information whatsoever on how to use CS1 for any other SPI device. Would you have any source code or other information that may be of help? Thanks, - Paul Paul Branham Software Engineer, EB ESSN HPN Security Hewlett-Packard Company 512-681-8511

Additional voltages
by Steven Zakulec 05 Jul '11

05 Jul '11

Hello, I've attached some additional voltages for a number of the remaining chips in flashchips.c. I have some questions about some of the remaining chips: Should the voltage range always be the most restrictive one offered, with others mentioned in the comments? Where can I find the datasheet for the Sanyo LF25FW203A ? Can I ignore the .REMS/etc text after a chip name when looking for the datasheet? Is it something I need to be aware of? Is there a difference for M25P40 and P40-old? For the W25Q64, it seems to be on the same datasheet as the Q80, Q16, and Q32, but it's only referenced once in the sheet, and makes me wonder if this is the correct sheet then. For other chips, I'm mostly still working on them. Signed-off-by: Steven Zakulec <spzakulec(a)gmail.com>

Author: uwe Date: Sun Jul 3 21:44:12 2011 New Revision: 1363 URL: http://flashrom.org/trac/flashrom/changeset/1363 Log: Fix and improve Windows/MinGW/MSYS build. - Makefile: Use $(OS_ARCH) to add some MinGW-specific workarounds and settings, so that a simple "make" is sufficient on MinGW (instead of manual Makefile hacking). - Explicitly set CC=gcc in the Makefile, otherwise you get an error like "cc: command not found" on MinGW. - MinGW doesn't have ffs(), use gcc's __builtin_ffs() instead. - Add /usr/local/include and /usr/local/lib to CPPFLAGS/LDFLAGS, that's where libusb-win32 and libftdi stuff is usually placed on MinGW/MSYS. - Disable serprog (no sockets) and all PCI-based programmers (no libpci) for now. That leaves dummy, ft2232_spi, and buspirate_spi enabled on MinGW per default. - serial.c: Use correct type for 'tmp', both on Windows/MinGW (DWORD) and POSIX (ssize_t).
