Re: [flashrom] [coreboot] Dualbios on GA-MA770-UD3

by Carl-Daniel Hailfinger

Hi Vadim, thanks for your mail. I have added the flashrom mailing list in CC: because we should develop a generic way to handle DualBIOS and similar techniques.

It will help us make a flashrom design decision that works for all boards with multiple flash chips. By the way, some of us have good contacts at ITE, so we can ask ITE for details about the undocumented registers. Regards, Carl-Daniel -- http://www.hailfinger.org/

[RFC] Layout handling...

by Carl-Daniel Hailfinger

Hi, before we change flashrom to work with current layout requirements, we should summarize the features we need/want, and then decide how to handle the individual layout regions internally. Terms: "write strategy" describes a combination of erase+write commands with a given block size, touching some blocks. "read protected" describes a region which can not be read. "write protected" describes a region which can not be written. "write once" describes a region which can be written exactly once in the chip lifetime. If you add a feature to the list, please give it a nickname so we know which feature people are referring to. Some of the features below might not be desirable, but I want to list them anyway so we can explicitly declare them as unsupported if needed. fullwrite-unrestricted: Write a chip-sized image, no special read/write restrictions of the chip, no layout file needs to be specified. Default write case right now. fullwrite-noread: Write a chip-sized image, reading anything from the chip is not possible. Many DVD writers fall in that category. No verification, violates our reliability guarantees. fullwrite-postread: Write a chip-sized image, reading anything from the chip is only possible after write. Chips which are read-locked until a full erase/write fall in that category. Do those exist as standalone flash chips or only integrated into processors? fullwrite-partialread: Write a chip-sized image, reading is only possible in some chip regions. Only partial verification, violates our reliability guarantees. fullwrite-partialwrite: Write a chip-sized image, but writing is only possible in some regions. This is obviously a conflict unless the image has the same contents as the chip in the write-protected regions and there is a possible write strategy for the whole image which does not touch the write-protected regions. Should flashrom always refuse this scenario, or only refuse it in case of conflicts? partialwrite-unrestricted: Write only parts of an image, the rest of the chip contents is kept, no special read/write restrictions. partialwrite-partialread: Write only parts of an image, the rest of the chip contents is kept, reading is only possible in some chip regions. If no read-protected regions are written and a suitable write strategy exists, should flashrom warn? If a read-protected region is written, should flashrom warn/refuse due to reliability requirements? partialwrite-partialwrite: Write only parts of an image, the rest of the chip contents is kept, writing is only possible in some chip regions. If no write-protected regions are written and a suitable write strategy exists, should flashrom warn? flashrom will refuse to write a write-protected region. fullread-unrestricted: Read the full chip, no special read restrictions of the chip. partialread-unrestricted: Read only parts of a chip, no special read restrictions of the chip. partialread-partialread: Read only parts of a chip, some regions are read-protected. flashrom should refuse to read any read-protected regions. partialread-imagefiller: If only parts of a chip are read and the read image has full chip size, what should be used as filler for unread regions? 0x00 or 0xff? partialread-layout-imagesize: If only parts of a chip are read, should the read image still have full chip size with all read regions filled in at the respective locations? partialread-layout-split: If only parts of a chip are read, should it be possible to write each region (or a combination thereof) to a separate image file, and would that mapping be specified in the layout file? partialwrite-layout-split: If only parts of a chip are written, should it be possible to collect each part of the new image from a separate image file, and would that mapping be specified in the layout file? readwrite-protection-time: Which read protection and write protection times exist? Temporary lock until unlock, temporary lock until chip soft reset, temporary lock until chip/programmer hard reset (powerdown or reset line), permanent eternal lock. readwrite-protection-type: Which read protection and write protection types exist? Programmer lock (e.g. Intel SPI), hardware chip lock (WP pin), software chip lock (chip command). readwrite-protection-interaction: How should we express this situation: A region is write-locked with a software chip lock, but to remove that software chip lock, a hardware chip lock has to be disabled first, then the software chip lock can be disabled. partialaccess-crash: Some regions in the chip are really off-limits and will cause an unrecoverable error (system crash) when accessed (read or write). That seems to be the case for some EC/flash interactions. Comments? Any forks of flashrom (e.g. chromium) which need infrastructure features not mentioned above?

[PATCH] Add Altera USB Blaster SPI programmer

Adds support for the Altera USB Blaster programming dongle in SPI mode. It has only been tested against a cheap clone ($10, unclear origin), and so is marked as not tested. It should also support several variants which are present on Altera dev boards (PID 6002,6003...), although I believe these are hardwired to their targets.

Maybe not a direct patch hunk conflict, but having a standalone function which verifies the flash chip according to some layout rules is a good thing. I'd keep verify_flash for now. OTOH, the hunk below makes it painfully obvious that the current verify_flash abstraction is not the right abstraction. Two functions compare_all_ranges() defaulting to a full chip range and verify_all_ranges() with similar characteristics would IMHO be a good abstraction, especially in light of the pending improved layout support. > - > int read_buf_from_file(unsigned char *buf, unsigned long size, > const char *filename) > { > @@ -1838,15 +1823,22 @@ int doit(struct flashctx *flash, int force, const char *filename, int read_it, > } > > if (verify_it) { > - /* Work around chips which need some time to calm down. */ > - if (write_it) > + msg_cinfo("Verifying flash...

(p. 98). other interesting bits of this chips: - bit#5 of the status register "is used in conjunction with the Block Protect (BP3, BP2, BP1, BP0) bits to determine if the protected area defined by the Block Protect bits starts from the top or the bottom of the memory array" - a flag status register that gives more info than the "legacy spi status register" - a non-volatile configuration register to configure dummy clock cycles, output driver strength and other stuff, and a volatile register that overrides the nvm settings the first two points can be somewhat ignored by us, the generic "write 0 to the status register" is good enough to unlock the device. regarding the ME: are you aware of my layout patches, that enable read, erase and verify on user-definable address ranges? see the patches from 2011-12-25 at http://patchwork.coreboot.org/project/flashrom/list/ -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner
