Hi so the output of my attempt to flash is sudo flashrom -V -w '/home/vince/Téléchargements/BIOS_R01-C0/61AO615.BIN' flashrom v0.9.4-r1394 on Linux 3.0.0-15-generic (x86_64), built with libpci 3.1.7, GCC 4.6.1, little endian flashrom is free software, get the source code at http://www.flashrom.org Calibrating delay loop...

Author: hailfinger Date: Thu Feb 9 00:28:54 2012 New Revision: 1490 URL: http://flashrom.org/trac/flashrom/changeset/1490 Log: SPI command black-/ignorelisting for the flash chip emulator in the dummy programmer Usage: flashrom -p dummy:spi_blacklist=commandlist flashrom -p dummy:spi_ignorelist=commandlist If commandlist is 0302, flashrom will refuse (blacklist) or ignore (ignorelist) command 0x03 (READ) and command 0x02 (WRITE). The commandlist can be up to 512 bytes (256 commands) long. Specifying flash chip emulation is a good idea to get useful results. Very useful for testing corner cases if you don't own a locked down Intel chipset and want to simulate such a thing.

Quite a few other SPI masters have the one-dummy-byte functionality as well. This needs to be implemented in a generic way (I have a totally bitrotted patch for it), but it should not hold back this patch. > - move sfdp_add_uniform_eraser to spi25.c for further use like > spi_get_erasefn_from_opcode? > - is setting the generic SPI unlock method safe? > - what page_size should be set? > > Tested-by: David Hendricks <dhendrix(a)google.com> > on W25Q64CV > > Signed-off-by: Stefan Tauner <stefan.tauner(a)student.tuwien.ac.at> > --- > Makefile | 2 +- > chipdrivers.h | 4 + > flash.h | 2 + > flashchips.c | 23 ++++ > flashchips.h | 1 + > flashrom.c | 28 +++++- > sfdp.c | 355 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++ > spi.h | 5 + > spi25.c | 31 +++++ > 9 files changed, 449 insertions(+), 2 deletions(-) > create mode 100644 sfdp.c > > diff --git a/Makefile b/Makefile > index 83aa038..b890d8a 100644 > --- a/Makefile > +++ b/Makefile > @@ -252,7 +252,7 @@ endif > CHIP_OBJS = jedec.o stm50flw0x0x.o w39.o w29ee011.o \ > sst28sf040.o m29f400bt.o 82802ab.o pm49fl00x.o \ > sst49lfxxxc.o sst_fwhub.o flashchips.o spi.o spi25.o sharplhf00l04.o \ > - a25.o at25.o opaque.o > + a25.o at25.o opaque.o sfdp.o > > LIB_OBJS = layout.o > > diff --git a/chipdrivers.h b/chipdrivers.h > index a1d0cd9..bd81098 100644 > --- a/chipdrivers.h > +++ b/chipdrivers.h > @@ -41,6 +41,7 @@ int spi_block_erase_d7(struct flashctx *flash, unsigned int addr, unsigned int b > int spi_block_erase_d8(struct flashctx *flash, unsigned int addr, unsigned int blocklen); > int spi_block_erase_60(struct flashctx *flash, unsigned int addr, unsigned int blocklen); > int spi_block_erase_c7(struct flashctx *flash, unsigned int addr, unsigned int blocklen); > +erasefunc_t *spi_get_erasefn_from_opcode(uint8_t opcode); > int spi_chip_write_1(struct flashctx *flash, uint8_t *buf, unsigned int start, unsigned int len); > int spi_chip_write_256(struct flashctx *flash, uint8_t *buf, unsigned int start, unsigned int len); > int spi_chip_read(struct flashctx *flash, uint8_t *buf, unsigned int start, int unsigned len); > @@ -58,6 +59,9 @@ int spi_read_chunked(struct flashctx *flash, uint8_t *buf, unsigned int start, u > int spi_write_chunked(struct flashctx *flash, uint8_t *buf, unsigned int start, unsigned int len, unsigned int chunksize); > int spi_aai_write(struct flashctx *flash, uint8_t *buf, unsigned int start, unsigned int len); > > +/* sfdp.c */ > +int probe_spi_sfdp(struct flashctx *flash); > + > /* opaque.c */ > int probe_opaque(struct flashctx *flash); > int read_opaque(struct flashctx *flash, uint8_t *buf, unsigned int start, unsigned int len); > diff --git a/flash.h b/flash.h > index e51b6d4..6bcae71 100644 > --- a/flash.h > +++ b/flash.h > @@ -174,6 +174,8 @@ struct flashctx { > struct registered_programmer *pgm; > }; > > +typedef int (erasefunc_t)(struct flashctx *flash, unsigned int addr, unsigned int blocklen); I believe that typedef to be pretty unreadable, but I see that avoiding the typedef would probably be even worse. > + > #define TEST_UNTESTED 0 > > #define TEST_OK_PROBE (1 << 0) > diff --git a/flashchips.c b/flashchips.c > index 0c8257b..b22e709 100644 > --- a/flashchips.c > +++ b/flashchips.c > @@ -8872,6 +8872,29 @@ const struct flashchip flashchips[] = { > .read = read_memmapped, > .voltage = {3000, 3600}, /* Also has 12V fast program */ > }, > + > + { > + .vendor = "Unknown", > + .name = "SFDP device", > + .bustype = BUS_SPI, > + .manufacture_id = GENERIC_MANUF_ID, > + .model_id = SFDP_DEVICE_ID, > + /* We present our own "report this" text hence we do not > + * want the default "This flash part has status UNTESTED..." > + * text to be printed. */ > + .tested = TEST_OK_PREW, > + .probe = probe_spi_sfdp, > + .unlock = spi_disable_blockprotect, /* is this safe? */ Should be safe AFAICS, but that's not a hard statement, it's a gut feeling. > + .read = spi_chip_read, > + .page_size = 256, /* ? */ Argh, page_size comes to bite us again.

[PATCH] dummy programmer: blacklist SPI commands
by Carl-Daniel Hailfinger 08 Feb '12

08 Feb '12

Add optional SPI command blacklisting to the flash chip emulator in the dummy programmer. Usage: flashrom -p dummy:spi_blacklist=hexstring If hexstring is 0302, flashrom will blacklist command 0x03 (READ) and command 0x02 (WRITE). The hexstring can have up to 521 bytes (256 commands) length, and must not start with 0x. TODO: Should 0x at the beginning of hexstring be tolerated? Very useful for testing corner cases if you don't own a locked down Intel chipset and want to simulate such a thing.
