* DJGPP: Avoid leaking memory on lowmem mapping errorCarl-Daniel Hailfinger2010-10-051-1/+5
| | | | | | | | | Add a clarifying comment about why low memory is never unmapped. Corresponding to flashrom svn r1195. Signed-off-by: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006@gmx.net> Acked-by: Rudolf Marek <r.marek@assembler.cz>
* Add support for building flashrom against libpayloadPatrick Georgi2010-09-301-1/+40
| | | | | | | | | | | This doesn't include changes to the frontend which must be done separately, so this won't work out of the box. This code was tested on hardware.

* Implement libpayload support and improve life for DOS based flashrom, tooPatrick Georgi2010-09-251-9/+14
| | | | | | | | | | | | | | Corresponding to flashrom svn r1181. Change the physmap* behaviour to use (void*)-1 as error code instead of NULL. That way, 1:1 mapped memory can be supported properly because (void*)0 is not a magic pointer anymore. (void*)-1 on the other hand is a rather unlikely memory offset, so that should be safe.

* Kill global variables, constants and functions if local scope sufficesCarl-Daniel Hailfinger2010-07-031-5/+5
| | | | | | | | | | | | | | | | | | | | | | | Constify variables where possible. Initialize programmer-related variables explicitly in programmer_init to allow running programmer_init from a clean state after programmer_shutdown. Prohibit registering programmer shutdown functions before init or after shutdown. Kill some dead code. Rename global variables with namespace-polluting names. Use a previously unused locking helper function in sst49lfxxxc.c. This is needed for libflashrom. Effects on the binary size of flashrom are minimal (300 bytes shrinkage), but the data section shrinks by 4384 bytes, and that's a good thing if flashrom is operating in constrained envionments.

* Add OpenBSD supportCarl-Daniel Hailfinger2010-07-021-0/+4
| | | | | | | | | | | | | | Add a requirements section to the man page which lists the needed access permissions for each programmer. This feature needs my pciutils/libpci 8/16-bit write emulation patch at http://marc.info/?l=openbsd-ports&m=127780030728045 titled [PATCH] Fix pciutils non-32bit PCI write on OpenBSD Corresponding to flashrom svn r1067.

* Remove unneeded #include statements completelyCarl-Daniel Hailfinger2010-05-301-4/+6
| | | | | | | | | | | | | | | Unistd.h was only used to get a definition of NULL in all files. Add our own NULL #define and remove unistd.h from flash.h stdio.h has no place in flash.h, it should be included only in files which really need it. Add #include statements in individual .c files where needed. Replace a few printf with msg_* to eliminate the need for stdio.h. Corresponding to flashrom svn r1021.

* Handle the following architectures in generic flashrom codeCarl-Daniel Hailfinger2010-05-261-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - x86/x86_64 (little endian) - PowerPC (big endian) - MIPS (big+little endian) No changes to programmer specific code. This means any drivers with MMIO access will _not_ suddenly start working on big endian systems, but with this patch everything is in place to fix them. Compilation should work on all architectures listed above for all drivers except nic3com and nicrealtek which require PCI Port IO which is x86-only for now. To compile without nic3com and nicrealtek, run make distclean make CONFIG_NIC3COM=no CONFIG_NICREALTEK=no Thanks to Misha Manulis for testing early versions of this patch on PowerPC (big endian) with the satasii programmer. Thanks to Segher Boessenkool for design review and for helping out with compiler tricks and pointing out that we need eieio on PowerPC. Thanks to Vladimir Serbinenko for compile testing on MIPS (little endian) and PowerPC (big endian) and for runtime testing on MIPS (little endian). Thanks to David Daney for compile testing on MIPS (big endian). Thanks to Uwe Hermann for compile and runtime testing on x86_64. DO NOT RUN flashrom ON NON-X86 AFTER APPLYING THIS PATCH! This patch only provides the infrastructure, but does not convert any drivers, so flashrom will compile, but it won't do the right thing on non-x86 platforms. Corresponding to flashrom svn r1013.

* Fix the DOS portRudolf Marek2010-04-251-32/+33
| | | | | | | | | | | | Now the DS selector limit is set to 4GB and all mmio accesses goes through DS, the 1:1 mapping is fixed so the _DS base is taken onto account. Plus is that the hwaccess.c needs no change and memcpy etc can be used on mmaped space. Corresponding to flashrom svn r995.

* 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.

* 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.
