* Rework internal bus handling and laptop bail-outNico Huber2019-06-061-31/+39
| | | | | | | | | | | | | | | | | | | | | | We used to bail out on any unknown laptop. However, modern systems with SPI flashes don't suffer from the original problem. Even if a flash chip is shared with the EC, the latter has to expect the host to send regular JEDEC SPI commands any time. So instead of bailing out, we limit the set of buses to probe. If we suspect to be running on a laptop, we only allow probing of SPI and opaque programmers. The user can still use the existing force options to probe all buses. This will obsolete some board-enables that could be moved to `print.c` in follow-up commits.

But practical concerns (i.e., bugs) have meant we don't quite do this. For reads: Bug https://b/35573113 shows that some SPI-based MTD drivers don't yet handle very large transactions. So we artificially limit this to block-sized chunks. For writes: It's not clear there is a hard limit. Some drivers will already split large writes into smaller chunks automatically. Others don't do any splitting. At any rate, using *small* chunks can actually be a problem for some devices (b:35104688), as they get worse performance (doing an internal read/modify/write). This could be fixed in other ways by advertizing their true "write chunk size" to user space somehow, but this isn't so easy. As a simpler fix, we can just increase the loop increment to match the read loop. Per David, the original implementation (looping over page chunks) was just being paranoid. So this patch: * clarifies comments in linux_mtd_read(), to note that the chunking is somewhat of a hack that ideally can be fixed (with bug reference) * simplifies the linux_mtd_write() looping to match the structure in linux_mtd_read(), including dropping several unnecessary seeks, and correcting the error messages (they referred to "reads" and had the wrong parameters) * change linux_mtd_write() to align its chunks to eraseblocks, not page sizes Note that the "->page_size" parameter is still somewhat ill-defined, and only set by the upper layers for "opaque" flash. And it's not actually used in this driver now. If we could figure out what we really want to use it for, then we could try to set it appropriately.

* Automatically release I/O permissions on shutdownCarl-Daniel Hailfinger2012-07-211-2/+2
| | | | | | | | | | | | | | | | | | | | | 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. Corresponding to flashrom svn r1551.

* Fix parallel-style programmer access from ITE IT87/Winbond W83627 SPICarl-Daniel Hailfinger2012-03-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | The ITE IT87 SPI driver uses a trick to speed up reading and writing: If a flash chip is 512 kByte or less, the flash chip can be completely mapped in memory and both read and write accesses are faster that way. The current IT87 SPI code did use the parallel programmer interface for memory mapped reads and writes, but that's the wrong abstraction. It has been fixed to use mmio_read*/mmio_write* for that purpose. The Winbond W83627 SPI driver uses the same trick in its read path for all supported chip sizes. Fix it the same way. Switch internal_chip_readn to use mmio_readn as proper abstraction. Kudos to Michael Karcher for spotting the bugs.

* Use shutdown callback mechanism to shutdown programmersDavid Hendricks2011-06-141-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | 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").

* Revamp board-specific quirk handling, allow for laptop supportCarl-Daniel Hailfinger2011-05-051-3/+10
| | | | | | | | | | | | | | | | | | | | | | | | Handle board-specific quirks in three phases: 1. Before Super I/O probing (e.g. blacklisting of some Super I/O probes, or unhiding the Super I/O) 2. Before the laptop enforcement decision (e.g. whitelisting a laptop for flashing) 3. After chipset enabling (all current board enables) Implementation note: All entries in board_pciid_enables get an additional phase parameter. Alternative variants (3 tables instead of 1) also have their downsides, and I chose table bloat over table multiplication). With this patch, it should be possible to whitelist supported laptops with a matching entry (phase P2) in board_pciid_enables which points to a function setting laptop_ok=1. (In case DMI is broken, matching might be a little bit more difficult, but it is still doable.) Corresponding to flashrom svn r1294.

Allow detection and initialization of up to 3 Super I/O and/or EC chips. WARNING! If a Super I/O or EC responds on multiple ports (0x2e and 0x4e), the code will do the wrong thing (namely, initialize the hardware twice). I have no idea if we should handle such situations, and whether we should ignore the second chip with identical ID or not. Initializing the hardware twice for the IT87* family is _not_ a problem, but I don't know how well IT85* can handle it (and whether IT85* would listen at more than one port anyway).
