* 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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* Kill central list of SPI programmersMichael Karcher2011-05-111-3/+0
| | | | | | | | | | | | | | | | | | 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").

* Revert MMIO space writes on shutdown as neededCarl-Daniel Hailfinger2011-05-031-0/+8
| | | | | | | | | | | | | | | | | | Reversible MMIO space writes now use rmmio_write*(). Reversible PCI MMIO space writes now use pci_rmmio_write*(). If a MMIO value needs to be queued for restore without writing it, use rmmio_val*(). MMIO space writes which are one-shot (e.g. communication with some chip) should continue to use the permanent mmio_write* variants. Corresponding to flashrom svn r1292.

* Remove vendorid parameter from pcidev_init()Carl-Daniel Hailfinger2011-03-071-2/+1
| | | | | | | | | | | | | | | 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. Fix compilation of flashrom with only the nicrealtek driver. Corresponding to flashrom svn r1274.

* SPI bitbanging: request/release busCarl-Daniel Hailfinger2010-09-151-10/+2
| | | | | | | | | | | | | | | | | | | | | | | | | SPI bitbanging on devices which speak SPI natively has a dual-use problem: We need to shut down normal SPI operations to do the bitbanging ourselves. Once we're done, it makes a lot of sense to reenable "normal" SPI operations again. Add request_bus/release_bus functions to struct bitbang_spi_master. Add a bitbang shutdown function (not used yet). Change MCP SPI and Intel NIC SPI to use the new request/release bus infrastructure. Cosmetic changes to a few error messages (80 column limit). There are multiple possible strategies for bus request/release: - Request at the start of a SPI command, release immediately afterwards. - Request at the start of a SPI multicommand, release once all commands of the multicommand are done. - Request on programmer init, release on shutdown. Each strategy has its own advantages. For now, we will stay with the first strategy which worked fine so far. Corresponding to flashrom svn r1171.

Tested on a 82541PI (0x8086, 0x107c) using 32-bit hardware. The last line in nicintel_request_spibus() could be changed so that FL_BUSY is used instead. Shortened sample log: [...] Found "Intel 82541PI Gigabit Ethernet Controller" (8086:107c, BDF 01:03.0). Found chip "ST M25P10.RES" (128 KB, SPI) at physical address 0xfffe0000.
