Carl-Daniel Hailfinger a5bcbceb58 Rename programmer registration functions
Register_programmer suggests that we register a programmer. However,
that function registers a master for a given bus type, and a programmer
may support multiple masters (e.g. SPI, FWH). Rename a few other
functions to be more consistent.

Niklas Söderlund 89edf36c17 Add additional error handling to pcidev_readbar() callers
This is mostly a leftover of Niklas' "remove exit call from pcidev_init" patch.
While not explicitly necessary detecting errors early is usually a good idea.

Carl-Daniel Hailfinger a2faddf7d3 Decouple BAR reading from pci device init, handle errors gracefully
Pcidev_init() now returns struct pci_device * instead of a BAR stored in
PCI config space. This allows for real error checking instead of having
exit(1) everywhere in pcidev.c.
Thanks to Niklas Söderlund for coming up with the original error
handling patch which was slightly modified and folded into this patch.
Move the declaration of struct pci_device in programmer.h before the
first user.

Stefan Tauner 5561955b11 Unify PCI init and let pcidev clean itself up
Previously the internal programmer used its own code to initialize pcilib.
This patch extracts the common code from the internal programmer and
pcidev_init() into pcidev_init_common().
This fixes the non-existent PCI cleanup of the internal programmer and adds
an additional safety by checking for an already existing PCI context.

We got a nice shutdown function registration infrastructure, but did not use it
very wisely. Instead we added shutdown functions to a myriad of programmers
unnecessarily. In this patch we get rid of those that do only call pci_cleanup(pacc)
by adding a shutdown function the pcidev.c itself that gets registered by
pcidev_init().

Stefan Tauner 4b24a2d70b Unify usbdev_status and pcidev_status into dev_entry
Once upon a time usbdev_status was created for the ft2232
programmer. Its IDs are semantically different to pcidev_status
because they indicate USB instead of PCI IDs, but apart from that
both data structures are equal. This change makes life easier for
everything involved in handling and printing the status of devices
that is noted in those structures by combining them into dev_entry.

It is still possible to distinguish between PCI and USB devices
indirectly by using the struct programmer's type field.

Also, add a programmer column to the PCI and USB devices lists.

Carl-Daniel Hailfinger 1c6d2ff03d Some ISO C fixes
This patch just fixes a limited number of bits not conforming to c99 by using
 - __asm__ instead of just asm
 - {0} instead of {} for struct initialization
 - h_addr_list[0] instead of h_addr to access the host address in
   struct hostent
 - #include <strings.h> where needed (for ffs and strcasecmp)

Based on a previous patch by Carl-Daniel.

Carl-Daniel Hailfinger d6bb828b01 Automatically release I/O permissions on shutdown
Get_io_perms() is renamed to rget_io_perms() and automatically registers
a function to release I/O permissions on shutdown.

Actually release I/O permissions on Solaris and iopl()-supporting
operating systems like Linux.

This patch fixes quite a few programmers which forgot to release I/O
permissions on shutdown, and it simplifies the shutdown and error
handling code for all others.

Do not call exit(1) if I/O permissions are denied and return an error
instead. This part of the patch was written by Niklas Söderlund.

David Hendricks 8bb2021d77 Use shutdown callback mechanism to shutdown programmers
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).

Carl-Daniel Hailfinger 40446eef1b Remove vendorid parameter from pcidev_init()
Simplify pcidev_init by killing the vendorid parameter which was pretty
useless anyway since it was present in the pcidevs parameter as well.

This also allows us to handle multiple programmers with different vendor
IDs in the same driver.

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

Carl-Daniel Hailfinger 744132af4b Various places in the flashrom source feature custom parameter extraction from programmer_param
This led to wildly differing syntax for programmer parameters, and
it also voids pretty much every assumption you could make about
programmer_param. The latter is a problem for libflashrom.

Use extract_param everywhere, clean up related code and make it more
foolproof. Add two instances of exit(1) where we have no option to
return an error. Remove six instances of exit(1) where returning an
error was possible.

WARNING: This changes programmer parameter syntax for a few programmers!

Carl-Daniel Hailfinger ad3cc55e13 Kill global variables, constants and functions if local scope suffices
Constify variables where possible.
Initialize programmer-related variables explicitly in programmer_init to
allow running programmer_init from a clean state after
programmer_shutdown.
Prohibit registering programmer shutdown functions before init or after
shutdown.
Kill some dead code.
Rename global variables with namespace-polluting names.
Use a previously unused locking helper function in sst49lfxxxc.c.

This is needed for libflashrom.

Effects on the binary size of flashrom are minimal (300 bytes
shrinkage), but the data section shrinks by 4384 bytes, and that's a
good thing if flashrom is operating in constrained envionments.

Carl-Daniel Hailfinger cceafa2ad0 Handle the following architectures in generic flashrom code
- x86/x86_64 (little endian)
- PowerPC (big endian)
- MIPS (big+little endian)

No changes to programmer specific code. This means any drivers with MMIO
access will _not_ suddenly start working on big endian systems, but with
this patch everything is in place to fix them.

Compilation should work on all architectures listed above for all
drivers except nic3com and nicrealtek which require PCI Port IO which is
x86-only for now.

To compile without nic3com and nicrealtek, run
make distclean
make CONFIG_NIC3COM=no CONFIG_NICREALTEK=no

Thanks to Misha Manulis for testing early versions of this patch on
PowerPC (big endian) with the satasii programmer.
Thanks to Segher Boessenkool for design review and for helping out with
compiler tricks and pointing out that we need eieio on PowerPC.
Thanks to Vladimir Serbinenko for compile testing on MIPS (little
endian) and PowerPC (big endian) and for runtime testing on MIPS (little
endian).
Thanks to David Daney for compile testing on MIPS (big endian).
Thanks to Uwe Hermann for compile and runtime testing on x86_64.

DO NOT RUN flashrom ON NON-X86 AFTER APPLYING THIS PATCH!
This patch only provides the infrastructure, but does not convert any
drivers, so flashrom will compile, but it won't do the right thing on
non-x86 platforms.
