* Introduce a type "chipaddr" to abstract the offsets within flash regionsCarl-Daniel Hailfinger2009-05-161-10/+10
| | | | | | | | | | | | | | | | | | | 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.

* Add generic 16 bit and 32 bit chip read/write emulation to the external ↵Carl-Daniel Hailfinger2009-05-161-0/+31
| | | | | | | | | | | | | flasher infrastructure The emulation works by splitting 32 bit accesses into 16 bit accesses and 16 bit accesses into to 8 bit accesses. That way, external flashers can mix and match the amount of emulation they need. Corresponding to flashrom svn r517.

* Unify usage of iopl-like code by introducing get_io_perms()Uwe Hermann2009-05-141-5/+10
| | | | | | | | | | Factor out portable iopl()-style code into a global function which all programmers can use, add missing close() call. Corresponding to flashrom svn r511. Signed-off-by: Uwe Hermann <uwe@hermann-uwe.de> Acked-by: Uwe Hermann <uwe@hermann-uwe.de>
* nic3com: allow selection of a particular PCI device to use as programmerChristian Ruppert2009-05-141-0/+11
| | | | | | | | | | | | Add support for users to specify a certain NIC via PCI bus:slot.func notation, in case there are multiple NICs in one system.

* Add external flasher supportCarl-Daniel Hailfinger2009-05-081-0/+154
- Read/write accesses through function pointers - Command line parameter for internal/external flasher - Board and chipset setup moved to internal init function - Shutdown stuff moved to internal shutdown function As a side benefit, this will allow us to undo chipset write enable during shutdown. Tested by Uwe on real hardware. Corresponding to flashrom svn r476. Signed-off-by: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006@gmx.net> Acked-by: Uwe Hermann <uwe@hermann-uwe.de>
