      Use struct flashctx instead of struct flashchip for flash chip access · 63fd9026
      Carl-Daniel Hailfinger authored 
      
Struct flashchip is used only for the flashchips array and for
operations which do not access hardware, e.g. printing a list of
supported flash chips.

struct flashctx (flash context) contains all data available in
struct flashchip, but it also contains runtime information like
mapping addresses. struct flashctx is expected to grow additional
members over time, a prime candidate being programmer info.
struct flashctx contains all of struct flashchip with identical
member layout, but struct flashctx has additional members at the end.

The separation between struct flashchip/flashctx shrinks the memory
requirement of the big flashchips array and allows future extension
of flashctx without having to worry about bloat.

      Use shutdown callback mechanism to shutdown programmers · 8bb2021d
      David Hendricks authored 
      This patch attempts to resolve some programmer shutdown ordering issues
by having the programmer init functions register shutdown callbacks explicitly
wherever it makes most sense. Before, assumptions were made that could lead to
the internal programmer's state changing before the external programmer could be
shut down properly. Now, each programmer cleans up after itself and (hopefully)
performs each operation in the correct order.

As a side-effect, this patch gives us a better usage model for reverse
operations such as rpci_* and rmmio_*. In the long-run, this should make
reversing the initialization process easier to understand, less tedious, and
less error-prone.

In short, this patch does the following:
- Registers a shutdown callback during initialization for each programmer.
- Kills the .shutdown function pointer from programmer_entry struct. Also,
  make most shutdown functions static.
- Adds a few minor clean-ups and corrections (e.g. missi...

      Kill central list of SPI programmers · b9dbe48b
      Michael Karcher authored 
      
Remove the array spi_programmer, replace it by dynamic registration
instead. Also initially start with no busses supported, and switch to
the default non-SPI only for the internal programmer.

Also this patch changes the initialization for the buses_supported variable
from "everything-except-SPI" to "nothing". All programmers have to set the
bus type on their own, and this enables register_spi_programmer to just add
the SPI both for on-board SPI interfaces (where the internal programmer
already detected the other bus types), as well as for external programmers
(where we have the default "none").

      Split off programmer.h from flash.h · 5b997c3e
      Carl-Daniel Hailfinger authored 
      
Programmer specific functions are of absolutely no interest to any file
except those dealing with programmer specific actions (special SPI
commands and the generic core).

The new header structure is as follows (and yes, improvements are
possible):
flashchips.h  flash chip IDs
chipdrivers.h  chip-specific read/write/... functions
flash.h  common header for all stuff that doesn't fit elsewhere
hwaccess.h hardware access functions
programmer.h  programmer specific functions
coreboot_tables.h  header from coreboot, internal programmer only
spi.h SPI command definitions

      Dediprog SF100 support · d38fac8c
      Carl-Daniel Hailfinger authored 
      
Reverse engineered from USB logs. I never touched that programmer nor
did I ever see the associated software.
Disabled by default until it is complete. The driver needs to be hooked
up to the SPI core before it will do anything besides init and
diagnostics.

I successfully reverse engineered all commands, but some are still
somewhat magic.
Logs from "flashrom -p dediprog -V" are appreciated.

Probe and read should work, erase/write is expected to explode.
The programmer will set voltage to 0 on exit.

Thanks a lot to Stefan Reinauer and Patrick Georgi for providing USB
logs and for testing the result.
