[commit] r719 - trunk
by svn＠flashrom.org 04 Sep '09

04 Sep '09

Author: hailfinger Date: 2009-09-05 04:30:58 +0200 (Sat, 05 Sep 2009) New Revision: 719 Modified: trunk/flash.h trunk/flashchips.c trunk/flashrom.c trunk/ft2232_spi.c trunk/it87spi.c trunk/sb600spi.c trunk/spi.c trunk/w39v040c.c Log: This is a patch which stores eraseblock sizes and corresponding block erase functions in struct flashchip. I decided to fill in the info for a few chips to illustrate how this works both for uniform and non-uniform sector sizes. struct eraseblock{ int size; /* Eraseblock size */ int count; /* Number of contiguous blocks with that size */ }; struct eraseblock doesn't correspond with a single erase block, but with a group of contiguous erase blocks having the same size. Given a (top boot block) flash chip with the following weird, but real-life structure: top 16384 8192 8192 32768 65536 65536 65536 65536 65536 65536 65536 bottom we get the following encoding: {65536,7},{32768,1},{8192,2},{16384,1} Although the number of blocks is bigger than 4, the number of block groups is only 4. If you ever add some flash chips with more than 4 contiguous block groups, the definition will not fit into the 4-member array anymore and gcc will recognize that and error out. No undetected overflow possible. In that case, you simply increase array size a bit. For modern flash chips with uniform erase block size, you only need one array member anyway. Of course data types will need to be changed if you ever get flash chips with more than 2^30 erase blocks, but even with the lowest known erase granularity of 256 bytes, these flash chips will have to have a size of a quarter Terabyte. I'm pretty confident we won't see such big EEPROMs in the near future (or at least not attached in a way that makes flashrom usable). For SPI chips, we even have a guaranteed safety factor of 4096 over the maximum SPI chip size (which is 2^24). And if such a big flash chip has uniform erase block size, you could even split it among the 4 array members. If you change int count to unsigned int count, the storable size doubles. So with a split and a slight change of data type, the maximum ROM chip size is 2 Terabytes. Since many chips have multiple block erase functions where the eraseblock layout depends on the block erase function, this patch couples the block erase functions with their eraseblock layouts. struct block_eraser { struct eraseblock{ unsigned int size; /* Eraseblock size */ unsigned int count; /* Number of contiguous blocks with that size */ } eraseblocks[NUM_ERASEREGIONS]; int (*block_erase) (struct flashchip *flash, unsigned int blockaddr, unsigned int blocklen); } block_erasers[NUM_ERASEFUNCTIONS]; Signed-off-by: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006(a)gmx.net> Acked-by: Stefan Reinauer <stepan(a)coresystems.de> Modified: trunk/flash.h =================================================================== --- trunk/flash.h 2009-09-05 01:31:32 UTC (rev 718) +++ trunk/flash.h 2009-09-05 02:30:58 UTC (rev 719) @@ -149,6 +149,17 @@ CHIP_BUSTYPE_UNKNOWN = CHIP_BUSTYPE_PARALLEL | CHIP_BUSTYPE_LPC | CHIP_BUSTYPE_FWH | CHIP_BUSTYPE_SPI, }; +/* + * How many different contiguous runs of erase blocks with one size each do + * we have for a given erase function? + */ +#define NUM_ERASEREGIONS 5 + +/* + * How many different erase functions do we have per chip? + */ +#define NUM_ERASEFUNCTIONS 5 + struct flashchip { const char *vendor; const char *name; @@ -177,6 +188,19 @@ /* Delay after "enter/exit ID mode" commands in microseconds. */ int probe_timing; int (*erase) (struct flashchip *flash); + + /* + * Erase blocks and associated erase function.

[PATCH] Reduce probe code duplication, fix 82802AB
by Carl-Daniel Hailfinger 04 Sep '09

Quite a few probe functions in flashrom are copies of probe_jedec with additional lock bit printing or other glue. Make them call probe_jedec instead. Use the correct reset sequence for 82802AB.

Author: hailfinger Date: 2009-09-05 03:16:30 +0200 (Sat, 05 Sep 2009) New Revision: 717 Modified: trunk/82802ab.c trunk/stm50flw0x0x.c trunk/w39v040c.c trunk/w39v080fa.c Log: Quite a few probe functions in flashrom are copies of probe_jedec with additional lock bit printing or other glue. Make them call probe_jedec instead. Use the correct reset sequence for 82802AB. Detailed explanation: The reset sequence before ID reading was correct, so ID always worked. But the reset sequence after ID reading was a copy-paste leftover from probe_jedec and didn't have any effect. I dug up flash_and_burn from the freebios-v1 tree and found out that 82802ab.c was indeed a copy of jedec.c with lots of experimental unannotated #if 0 and #if 1. About the wait_82802ab change: Before the patch, wait_82802ab entered read status mode, switched to ID mode, then tried an incorrect and unsupported JEDEC command to exit ID mode. Nobody ever saw that this failed because all subsequent function calls had the correct reset sequence at the beginning. With the patch, wait_82802ab enters read status mode, then switches back to read mode with the official reset command.
