* Add support for Intel Silvermont: Bay Trail, Rangeley and AvotonDuncan Laurie2014-08-201-6/+8
| | | | | | | | | | | | | | | | | | | | | | The core of this patch to support Bay Trail originally came from the Chromiumos flashrom repo and was modified by Sage to support the Rangeley/Avoton parts as well. Because that was not complicated enough already Stefan Tauner refactored and refined everything. Bay Trail seems to be the first Atom SoC able to support hwseq. No SPI Programming Guide could be obtained so it is handled similarly to Lynx Point which seems to be its nearest relative. Corresponding to flashrom svn r1844.

| | | | | | | | | | | | | | | Possible values as well as encodings have changed in newer chipsets as follows. - Pre-PCH (i.e. ICH) chipsets had a maximum frequency of 33 MHz for all operations - Since Cougar Point the chipsets support dual output fast reads (encoded in bit 30). - Flash component density encoding has changed from 3 to 4 bits with Lynx Point, currently allowing for up to 64 MB chips.

* ichspi: fix missing set_addr on erases and possible crossings of 256 B ↵Stefan Tauner2014-08-051-0/+8
| | | | | | | | | | | | | | | | | | boundaries Apparently the erase function did never set any address before issuing the erase commands. How could this ever work? Also, according to PCH documentation crossing 256 byte boundaries is invalid and may cause wraparound due to the flash chip's pages. Check for this on reads as well as writes.

* ichspi: ignore bogus FREGsStefan Tauner2012-08-271-1/+1
| | | | | | | | | | | | | | | | | | Some vendors forget to disable regions properly and set their FRAP bits and FREG to 0. While not documented publicly this is being ignored by the chipset(s)[1] and hence flashrom should do so too. Without this patch flashrom prints a warning and disables writes. The check for i (region index) excludes the descriptor region which should not be becessary because specs suggest that the descriptor region should not be locked, but if vendors would follow the specs this patch would not have been necessary in the first place.

* Fix VIA VX*** supportHelge Wagner2012-08-241-5/+3
| | | | | | | | | | | | | | | | | | | | | | Helge Wagner's patch that added VIA VX900 chipset support made me look closer at the datasheets which led to some concise documentation about newer VIA chipsets: http://flashrom.org/VIA Based on that this patch adds full support for VX800/VX820, VX855/VX875 and VX900, including SPI and LPC. VT8237S was not changed (SPI support only) because there is no public datasheet and it is not clear how to distinguish between LPC and SPI strapping and investigations in (NDAed) documents have not brought up anything conclusively. enable_flash_vt823x could probably be enhanced too due to various ignored LPC options of the chipset.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | All programmer types (Parallel, SPI, Opaque) now register themselves into a generic programmer list and probing is now programmer-centric instead of chip-centric. Registering multiple SPI/... masters at the same time is now possible without any problems. Handling multiple flash chips is still unchanged, but now we have the infrastructure to deal with "dual BIOS" and "one flash behind southbridge and one flash behind EC" sanely. A nice side effect is that this patch kills quite a few global variables and improves the situation for libflashrom. Hint for developers: struct {spi,par,opaque}_programmer now have a void *data pointer to store any additional programmer-specific data, e.g. hardware configuration info.

The separation between struct flashchip/flashctx shrinks the memory requirement of the big flashchips array and allows future extension of flashctx without having to worry about bloat.

* ichspi: add support for Intel Hardware SequencingStefan Tauner2011-11-081-10/+292
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on the new opaque programmer framework this patch adds support for Intel Hardware Sequencing on ICH8 and its successors. By default (or when setting the ich_spi_mode option to auto) the module tries to use swseq and only activates hwseq if need be: - if important opcodes are inaccessible due to lockdown - if more than one flash chip is attached. The other options (swseq, hwseq) select the respective mode (if possible). A general description of Hardware Sequencing can be found in this blog entry: http://blogs.coreboot.org/blog/2011/06/11/gsoc-2011-flashrom-part-1/ Besides adding hwseq this patch also introduces these unrelated changes: - Fix enable_flash_ich_dc_spi to pass ERROR_FATAL from ich_init_spi. The whole error handling looks a bit odd to me, so this patch does change very little. Also, it does not touch the tunnelcreek method, which should be refactored anyway. - Add null-pointer guards to find_opcode and find_preop to matches the other opcode methods better: curopcodes == NULL has some meaning and is actively used/checked in other functions.

* ichspi: use a variable to distinguish ich generations instead of ↵Stefan Tauner2011-11-061-52/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | spi_programmer->type The type member is enough most of the time to derive the wanted information, but - not always (e.g. ich_set_bbar), - only available after registration, which we want to delay till the end of init, and - we really want to distinguish between chipset version-grained attributes which are not reflected by the registered programmer. Hence this patch introduces a new static variable which is set up early by the init functions and allows us to get rid of all "switch (spi_programmer->type)" in ichspi.c. We reuse the enum introduced for descriptor mode for the type of the new variable. Previously magic numbers were passed by chipset_enable wrappers. Now they use the enumeration items too. To get this working the enum definition had to be moved to programmer.h. Another noteworthy detail: previously we have checked for a valid programmer/ich generation all over the place. I have removed those checks and added one single check in the init method. Calling any function of a programmer without executing the init method first, is undefined behavior.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on the work of Matthias 'mazzoo' Wenzel this patch adds pretty printing of those ICH/PCH flash descriptor sections that are cached/mapped by the chipset (and which are therefore reachable via FDOC/FDOD registers). this includes the following: - content section: describes the image and some generic properties (number of sections, offset of sections, PCH/ICH and MCH/PROC strap offsets and lengths) - component section: identify the different SPI flash chips and their capabilities. - region section similarly to a partition table this describes the different regions. the content of FLREG* is derived from this section. - master section defines SPI master (host, ME, GbE) access rights of the individual regions. the content of PR* is derived from this section. this is only a part of the data included in the descriptor. other information can be retrieved from a complete binary dump of the descriptor region only. this patch also adds macros and pretty printing for "Vendor Specific Component Capabilities" registers: there are two of them: lower and upper. they describe the properties of the address space divided by FPBA (which allows to use multiple flash chips or partitions with different properties). the properties of all supported flash chips (together with their RDIDs) are stored in the same format in table in a descriptor section (which is used by the ME apparently). a later patch will use the macros outside of ichspi.c which is the reason why the prettyprinting function and the register bit macros are not defined in ichspi.c but ich_descriptors.h (else they would be moved in the follow-up patch). because this patch relies on (compiler) implementation-specific layouting of bit-fields, it checks for correct layout before taking any action on runtime.
