confusion, after we had a grace period to get people to move over to the new repository. History stays available for the archaeologists and for ancient checkouts (potentially with local changes). Use "svn diff" to get local changes, and apply it to a newer tree (if you manage to apply it, that is).

2009-03-05flashrom: Use helper functions to access flash chips.Carl-Daniel Hailfinger
Right now we perform direct pointer manipulation without any abstraction to read from and write to memory mapped flash chips. That makes it impossible to drive any flasher which does not mmap the whole chip. Using helper functions readb() and writeb() allows a driver for external flash programmers like Paraflasher to replace readb and writeb with calls to its own chip access routines. This patch has the additional advantage of removing lots of unnecessary casts to volatile uint8_t * and now-superfluous parentheses which caused poor readability. I used the semantic patcher Coccinelle to create this patch. The semantic patch follows: @@ expression a; typedef uint8_t; volatile uint8_t *b; @@ - *(b) = (a); + writeb(a, b); @@ volatile uint8_t *b; @@ - *(b) + readb(b) @@ type T; T b; @@ ( readb | writeb ) (..., - (T) - (b) + b ) In contrast to a sed script, the semantic patch performs type checking before converting anything.

2008-09-26Activate proper support for EN29F002(A)(N)[BT].Mats Erik Andersson
Fully tested for Probe/Read/Erase/Write on EN29F002NT. Jedec subroutines 'probe_jedec()' and 'erase_chip_jedec()' are still in use, but a tailored 'write_en29f002a()' is needed due to a byte wise writing mechanism for this chip.

2007-12-31Add continuation ID support to jedec.cCarl-Daniel Hailfinger
The continuation ID code does not go further than checking for IDs of the type 0x7fXX, but does this for vendor and product ID. The current published JEDEC spec has a list where the largest vendor ID is 7 bytes long, but all leading bytes are 0x7f. The list will grow in the future, and using a 64bit variable will not be enough anymore. Besides that, it seems that the location of the ID byte after the first continuation ID byte is very vendor specific, so we may have to revisit that code some time in the future. (Suggestion for a new encoding: Use a two-byte data type for the ID, the lower byte contains the only non-0x7f byte, the upper byte contains the number of 0x7f bytes used as prefix, which is the bank number minus 1 the vendor ID appears in.) Add support for EON EN29F002AT.
