* parallel: Drop explicit fallback_chip_X boilerplateEdward O'Callaghan2023-01-111-6/+0
| | | | | | | | | | | | | | | | | | | | | | | A NULL func pointer is necessary and sufficient for the condition `NULL func pointer => fallback_chip_X' as to not need this explicit specification. Therefore drop the explicit need to specify these fallback callback function pointer in the par_master struct. This is a reasonable default for every driver in the tree. Furthermore, move the 'fallback_chip_X()' func from the generic programmer.c register logic into its relevant home of parallel.c and make static local to clean up link-time symbol space. This simplifies the code and driver development.

* drivers/: Make 'fallback_{un}map' the default unless definedEdward O'Callaghan2022-10-081-2/+0
| | | | | | | | | | | | | | | | | | | Drop the explicit need to specify the default 'fallback_{un}map' callback function pointer from the 'programmer_entry' struct. This is a reasonable default for every other driver in the tree with only a select few exceptions [atavia, serprog, dummyflasher and internal]. Thus this simplifies driver development and paves way to remove the 'programmer' global handle.

| | | | | | | | | | | | | | | | | | | 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(). Corresponding to flashrom svn r1642.

* Use shutdown callback mechanism to shutdown programmersDavid Hendricks2011-06-141-15/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

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. Corresponding to flashrom svn r1013.

* Only probe for chips with compatible bus protocolsCarl-Daniel Hailfinger2009-06-011-0/+2
| | | | | | | | | | | | | | | | | | It doesn't make sense to probe for SPI chips on a LPC host, nor does it make sense to probe for LPC chips on a Parallel host. This change is backwards compatible, but adding host protocol info to chipset init functions will speed up probing. Once all chipset init functions are updated and the Winbond W29EE011 and AMIC A49LF040A chip definitions are updated, the W29EE011 workaround can be deleted as the W29/A49 conflict magically disappears.

* Introduce a type "chipaddr" to abstract the offsets within flash regionsCarl-Daniel Hailfinger2009-05-161-4/+4
| | | | | | | | | | | | | | | | | | | 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.
