* Remove unneeded #include statements completely.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.

* Handle the following architectures in generic flashrom code: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.

* Create a physical memory mapping function which requests cached readonlyhailfinger2010-02-021-4/+51
| | | | | | | | | | | | | | | | | | | | | | | | memory. 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.

| | | | | | | | | | | | | | | | | | | | - 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.
