* Only probe for chips with compatible bus protocolsCarl-Daniel Hailfinger2009-06-011-0/+2
| | | | | | | | | | | | | | | | | | It doesn't make sense to probe for SPI chips on a LPC host, nor does it make sense to probe for LPC chips on a Parallel host. This change is backwards compatible, but adding host protocol info to chipset init functions will speed up probing. Once all chipset init functions are updated and the Winbond W29EE011 and AMIC A49LF040A chip definitions are updated, the W29EE011 workaround can be deleted as the W29/A49 conflict magically disappears.

It can be detected, read works, erase works, but write will need some additional code (will post in another patch later). Corresponding to flashrom svn r520.

* Introduce a type "chipaddr" to abstract the offsets within flash regionsCarl-Daniel Hailfinger2009-05-161-4/+4
| | | | | | | | | | | | | | | | | | | 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 Hermann2009-05-151-88/+12
| | | | | | | | | | | | | | | 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.

* Make the nic3com code check how many supported NICs are foundUwe Hermann2009-05-141-17/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we find multiple ones, abort with a message to the user, suggesting to use the flashrom -p nic3com=bb:dd.f syntax. If exactly one supported NIC is found, use it. If none is found, abort with an error. Print the bb:dd.f numbers for all supported NICs we find, so the user doesn't have to poke around in lspci output to find the desired bb:dd.f. Also, drop one pci_read_long() in favor of using the already existing base_addr[0] struct field. Drop the BAR in user messages, it's not really useful for us. Instead, explain the BDF syntax a bit more verbosely. While I'm at it, update the manpage some more to mention and fully document the external programmer support we have (or will have soon). The patch is tested on hardware: $ flashrom -p nic3com flashrom v0.9.0-r512 Found NIC "3COM 3C905C: EtherLink 10/100 PCI (TX)" (10b7:9200, BDF 05:04.0) Found NIC "3COM 3C905C: EtherLink 10/100 PCI (TX)" (10b7:9200, BDF 05:03.0) Error: Multiple supported NICs found.

* Add support for 3COM NICs as "external programmer" and Atmel AT49BV512Uwe Hermann2009-05-131-0/+170
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.
