* Create a physical memory mapping function which requests cached readonly memoryCarl-Daniel Hailfinger2010-02-021-4/+51
| | | | | | | | | | | | | | | | | | | | | | This should take care of picky Linux kernels which do not allow uncached mappings to cached areas. Handle mapping failure gracefully (no forced exit()) if the caller specifies it. Such cached areas which can handle mapping failure are DMI tables and coreboot tables. On failure we just ignore those tables. That is not perfect, but a lot better than aborting flashrom due to an error in nonessential functionality. This should fix flashrom on a sizable number of machines where it currently aborts early. Yes, I could have exploited a Linux kernel bug to "solve" this, but relying on such bugs is not exactly the best idea. Corresponding to flashrom svn r889.

| | | | | | | | | | | | So far, AMD Geode LX is the only user of this infrastructure. It needs /dev/cpu0 from ports/sysutils on FreeBSD during runtime on Geode LX. Corresponding to flashrom svn r690.

* Various smaller flashrom improvementsUwe Hermann2009-05-171-4/+4
| | | | | | | | | | | | | | | | | | - Document new 'satasii' programmer in -L output and manpage. - Drop PCI_IO_BASE_ADDRESS, pci.h has such #defines already. - Beautify flashrom output and make it more consistent. - Same for the 'make' output (reordered some $CC parameters). Build-tested on i386, shouldn't break any builds, I think. - Some variable renaming and other cosmetic fixes. Corresponding to flashrom svn r529.

* Abstract mapping/unmapping of flash regionsCarl-Daniel Hailfinger2009-05-111-0/+21
| | | | | | | | | | | | | | | | Flash mapping/unmapping was performed without an abstraction layer, so even the dummy flasher caused memory mappings to be set up. Add map/unmap functions to the external flasher abstraction. Fix a possible scribble-over-low-memory corner case which fortunately never triggered so far. With this patch, --programmer dummy works fine as non-root. Corresponding to flashrom svn r493.
