      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. missing physunmap() calls).

TODO: Remove forward declaration of serprog_shutdown() (added to simplify diff)

      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").

      Add support for the Open Graphics Project development card, OGD1, as a SPI flash programmer · 90021f28
      Mark Marshall authored 
      The project is in the the process of designing and making a complete,
open source, graphics card. More info at http://wiki.opengraphics.org

.

The first development card is a PCI add in card containing a couple of
FPGAs and a couple of serial flash chips (amongst other things). The
FPGAs are called XP10 and S3 (their part numbers). The XP10 contains its
own flash and does not need to be programmed by flashrom - it ensures
that the device can enumerate on the PCI bus without needing further
configuration.

The larger FPGA is the S3. This is configured from a large SPI flash
(2 MBytes). The second SPI flash is used to store the VGA BIOS. It is
smaller (128 KBytes). This patch adds support for programming either of
the two SPI flash chips.

The programmer device takes one configuration option which selects which
of the two flash chips is accessed. This must be set to either "cprom"
or "bprom". (The project refers to the two chips as "cprom" / "bprom",
"s3" and "bios" are more readable alternatives).

Add support for SST SST25VF010 (REMS). Mark SST SST25VF016B as tested
for write.

      Always read the flash chip before writing · 42d38a9d
      Carl-Daniel Hailfinger authored 
      
This will allow flashrom to skip erase of already-erased blocks and to
skip write of blocks which already have the wanted contents.

Avoid emergency messages by checking if the chip contents after a failed
write operation (erase/write) are unchanged.

Keep the emergency messages after a failed pure erase. That part is
debatable because if someone wants erase, he pretty sure doesn't care
about the flash contents anymore.

Please note that this introduces additional overhead of a full chip read
before write. This is frowned upon by people with slow programmers. A
followup patch will make this configurable.
