* treewide: Drop most cases of `sizeof(struct ...)`Angel Pons2021-06-091-1/+1
| | | | | | | | | | | | | | | | Spelling out the struct type name hurts readability and introduces opportunities for bugs to happen when the pointer variable type is changed but the corresponding sizeof is (are) not. TEST=`make CONFIG_EVERYTHING=yes CONFIG_JLINK_SPI=no VERSION=none -j` with and without this patch; the flashrom executable does not change.

* Add an internal DMI decoderSean Nelson2013-09-111-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously we had to rely on dmidecode to decode the DMI/SMBIOS table. This patch integrates a DMI decoder into flashrom. The old behavior of calling dmidecode can be brought back by using CONFIG_INTERNAL_DMI=no. Significant portions of this patch were taken from dmidecode, hence add its authors to the copyright notice (dmidecode is also GPL2+). We do a few things differently though. First of all we do more bounds checking to prevent accessing unmapped memory. We do not support disovery via EFI (yet), but memory scanning only. We handle the chassis-type lock bit correctly which dmidecode did not for a long while. The API to the rest of flashrom remains stable, but the output changes slightly. To share as much code as possible (which actually is not much), i have added dmi_fill methods that get called in dmi_init. They are reponsible to fill the dmi_strings array and setting the is_laptop variable. After it is called, dmi_init prints all dmi_strings. Previously the strings were printed in the order they were discovered, followed by the chassis-type, which is now output earlier (in dmi_fill). Because DJGPP does not support strnlen a simple implementation was added for it. This is still only available on x86; actually it is not even compiled in for other architectures at all anymore.

It seems to be quite likely that all AT25F512 are fully functional relabeled AT25F1024 chips.

| | | | | | | | | | | | | | | 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.

* 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.
