All programmer types (Parallel, SPI, Opaque) now register themselves
into a generic programmer list and probing is now programmer-centric
instead of chip-centric.
Registering multiple SPI/... masters at the same time is now possible
without any problems. Handling multiple flash chips is still unchanged,
but now we have the infrastructure to deal with "dual BIOS" and "one
flash behind southbridge and one flash behind EC" sanely.
A nice side effect is that this patch kills quite a few global variables
and improves the situation for libflashrom.
Hint for developers:
struct {spi,par,opaque}_programmer now have a void *data pointer to
store any additional programmer-specific data, e.g. hardware
configuration info.
Note:
flashrom -f -c FOO -r forced_read.bin
does not work anymore. We have to find an architecturally clean way to
solve this.
Corresponding to flashrom svn r1475.
