* Eliminate all 'inline's from the flashrom codeUwe Hermann2009-05-161-0/+52
| | | | | | | | | | | | They serve pretty much no purpose, compilers can optimize pretty much all of what we might mark as inline anyway, _and_ inlines are not enforced in any way by the compiler either.

* Introduce a type "chipaddr" to abstract the offsets within flash regionsCarl-Daniel Hailfinger2009-05-161-4/+3
| | | | | | | | | | | | | | | | | | | Use chipaddr instead of volatile uint8_t * because when we access chips in external flashers, they are not accessed via pointers at all. Benefits: This allows us to differentiate between volatile machine memory accesses and flash chip accesses. It also enforces usage of chip_{read,write}[bwl] to access flash chips, so nobody will unintentionally use pointers to access chips anymore. Some unneeded casts are removed as well. Grepping for chip operations and machine memory operations doesn't yield any false positives anymore. Compile tested on 32 bit and 64 bit Linux. Corresponding to flashrom svn r519.

* Refactor parts of the 3COM NIC codeUwe Hermann2009-05-151-2/+4
| | | | | | | | | | | | | | | Move the reusable PCI specific parts into pcidev.c, they'll be usable for other NIC code (Realtek, VIA, ...) and also for SATA/IDE controller cards as external programmers (for every PCI device which can program EEPROMs basically). Also add print_supported_pcidevs() to show the supported PCI devices (currently only NICs, soon more) in the 'flashrom -L' output. Corresponding to flashrom svn r515.

* Add support for 3COM NICs as "external programmer" and Atmel AT49BV512Uwe Hermann2009-05-131-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows flashrom to identify, read, write, erase and verify flash chips on (some) 3COM network cards. The patch uses the external programmer infrastructure, the network card is basically treated as an external flash programmer. Usage: $ ./flashrom -p nic3com flashrom v0.9.0-r498 Found NIC "3COM 3C905C: EtherLink 10/100 PCI (TX)" (10b7:9200), addr = 0xa400 Calibrating delay loop... OK. Found chip "Atmel AT49BV512" (64 KB) at physical address 0xffff0000. No operations were specified. $ ./flashrom -p nic3com -E flashrom v0.9.0-r498 Found NIC "3COM 3C905C: EtherLink 10/100 PCI (TX)" (10b7:9200), addr = 0xa400 Calibrating delay loop... OK. Found chip "Atmel AT49BV512" (64 KB) at physical address 0xffff0000. Erasing flash chip... SUCCESS. $ ./flashrom -p nic3com -wv backup.bin flashrom v0.9.0-r498 Found NIC "3COM 3C905C: EtherLink 10/100 PCI (TX)" (10b7:9200), addr = 0xa400 Calibrating delay loop... OK. Found chip "Atmel AT49BV512" (64 KB) at physical address 0xffff0000. Flash image seems to be a legacy BIOS. Disabling checks. Programming page: 1023 at address: 0x0000ffc0 Verifying flash... VERIFIED. $ ./flashrom -p nic3com -r backup.bin flashrom v0.9.0-r498 Found NIC "3COM 3C905C: EtherLink 10/100 PCI (TX)" (10b7:9200), addr = 0xa400 Calibrating delay loop... OK. Found chip "Atmel AT49BV512" (64 KB) at physical address 0xffff0000. Reading flash... done. I have tested this on actual hardware (see PCI IDs above) and all operations worked fine. Support for other 3COM cards will follow (I added some more which should be supportable by this code, but they're untested so far), as well as support for NICs from other vendors. The patch also adds support for the Atmel AT49BV512 which is soldered onto the 3COM NIC I used for testing. Corresponding to flashrom svn r499.

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

* Fix Elan SC520 handlingCarl-Daniel Hailfinger2009-05-091-2/+1
| | | | | | | | | | | | | | | | | | Flashbase is a variable which should never be set outside chipset code. It is only used to calculate the base address of the flash space at exactly one location in the code. Setting flashbase during probe caused subsequent probes to fail unless special handling code was used. We had such code and it caused every probe except the first to fail on Elan SC520. Remove the superfluous flashbase assignment and simplify the rest of the code. Corresponding to flashrom svn r488.

| | | | | | | | | | | | | | | | Flashrom assumes that the flash chip contents are available via mmap if no read function is defined. This special case is handled in lots of places all over the code. Remove the special case and use the read_memmapped function. Not only does this allow us to fix a read bug in flashrom I recently uncovered on ICH SPI, it also allows us to add support for Paraflasher to flashrom. Corresponding to flashrom svn r473.
