* Add struct flashctx * parameter to all functions accessing flash chipsCarl-Daniel Hailfinger2011-12-181-31/+34
| | | | | | | | | | | | | | | | All programmer access function prototypes except init have been made static and moved to the respective file. A few internal functions in flash chip drivers had chipaddr parameters which are no longer needed. The lines touched by flashctx changes have been adjusted to 80 columns except in header files.

* Use struct flashctx instead of struct flashchip for flash chip accessCarl-Daniel Hailfinger2011-12-141-5/+5
| | | | | | | | | | | | | | | | | | | | | | Struct flashchip is used only for the flashchips array and for operations which do not access hardware, e.g. printing a list of supported flash chips. struct flashctx (flash context) contains all data available in struct flashchip, but it also contains runtime information like mapping addresses. struct flashctx is expected to grow additional members over time, a prime candidate being programmer info. struct flashctx contains all of struct flashchip with identical member layout, but struct flashctx has additional members at the end. 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.

* Revert "Unsignify lengths and addresses in chip functions and structs"Stefan Tauner2011-09-181-1/+1
| | | | | | | | | | | | | | | | | | | | - probe_timing was changed to unsigned although we use negative values for special cases - some code was not changed along hence did no longer compile: * dediprog's read and write functions * linux_spi's read and write functions - it introduced a number of new sign conversion warnings (http://paste.flashrom.org/view.php?id=832) To be safe this patch reverts all changes made in r1448, a corrected patch will follow later.

* Move erase verification to generic codeCarl-Daniel Hailfinger2011-06-261-8/+2
| | | | | | | | | | | | Erase functions are no longer called from chip drivers and thus their internal erase verification can be moved to generic code. This also makes it easier to skip the verify step if desired and to differentiate between failed command submission and failed erase verification. Corresponding to flashrom svn r1353.

* Unify chip write functionsCarl-Daniel Hailfinger2010-10-101-13/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The currently used write functions (wrappers) all use helpers which perform the actual write (inner functions). The signature of the write wrappers is: int write_chip(struct flashchip *flash, uint8_t * buf); The signature of the inner write functions varied a lot. This patch changes them to: int write_part(struct flashchip *flash, uint8_t *src, int start, int len); Did you know that flashrom has only 8 inner write functions for all flash chips? write_page_write_jedec_common write_sector_jedec_common write_sector_28sf040 spi_chip_write_256_new spi_chip_write_1_new spi_aai_write_new write_page_82802ab write_page_m29f400bt Export all inner write functions. Change the function signature of wait_82802ab to eliminate single-use variables. Remove an error message in write_page_m29f400bt which was printed for every byte written regardless of success. Add sharplhf00l04.c to the list of flash chip drivers in the Makefile. While the functions in there are unused, I suspect we will need them later, and by hooking the file up we ensure that compilation won't break. Corresponding to flashrom svn r1208.

* Move implicit erase out of chip driversCarl-Daniel Hailfinger2010-10-081-21/+0
| | | | | | | | | | | | | | | | | | Flashrom had an implicit erase-on-write for most flash chip and programmer drivers, but it was not entirely consistent. Some drivers had their own hand-rolled partial update functionality which made handling partial updates from generic code impossible. Move implicit erase out of chip drivers, and kill some dead erase functions at the same time. A full chip erase is now performed in the generic code for all flash chips on write, and after that the whole chip is written. Corresponding to flashrom svn r1206.

* Use common jedec functionality where appropriateMichael Karcher2009-11-271-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | The deleted function in en29f002a.c is reintroduced as write_by_byte_jedec in jedec.c as it contains no chip-specific instructions. It is not yet used in other chip drivers, as key addresses (0x2AAA/0x5555) are often specified with less bits. After crosschecking datasheets, most of the fixmes can probably be resolved as indicated in them, causing significant code reduction. The common JEDEC code for bytewise programming does not program 0xFF at all. The chips that had a dedicated bytewise flash function which has been changed to write_jedec_1 thus changed flashing behaviour and the "write" test flag has been removed. This applies to: AMD Am29F002BB/Am29F002NBB AMD Am29F002BT/Am29F002NBT (TEST_OK_PREW before) AMIC A29002B AMIC A29002T (TEST_OK_PREW before) EON EN29F002(A)(N)B EON EN29F002(A)(N)T (TEST_OK_PREW before) Macronix MX29F001B (TEST_OK_PREW before) Macronix MX29F001T (TEST_OK_PREW before) Macronix MX29F002B Macronix MX29F002T (TEST_OK_PREW before) Macronix MX29LV040 Similar analysis should be performed for the read id stuff.

* Refine support for the JEDEC Software Data ProtectionMichael Karcher2009-11-261-11/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the extremely dangerous unprotect_jedec function which is not used at all within flashrom code, and renames the misleadingly named protect_jedec function to start_program_jedec. Calls to protect_jedec after flashing are removed, because a) on LPC chips, the command sent by protoct_jedec is not even in the datasheet and b) on parallel chips, the block write command issued before already contained the software protection sequence, so software protection is definitely enabled. This patch also removes two clones of protect_jedec Background: JEDEC Software Data Protection started as an optional feature, which was disabled on the first single-voltage-flash chips. The software data protection is the need to prefix a write with a magic "write enable" command, while without write protection every write access into the chip's address space modifies flash content. This magic write enable command also tells the flash chip that the programmer obviously support sending write-enable commands and turns off the "any write modifies flash content" mode. There also exist a two-command (6 writes) sequence that disables Software Data Protection completey, which should only ever be used to prepare updating with a device that can't handle software data protection.

| | | | | | | | | | | | | | | The __func__ variant is standardized in C99 and recommended to be used instead of __FUNCTION__ in the gcc info page. Only _very_ old versions of gcc did not know about __func__, but we've been using both __func__ and __FUNCTION__ for a long while now, and nobody complained about this, so all our users seem to use recent enough compilers.

* Introduce a type "chipaddr" to abstract the offsets within flash regionsCarl-Daniel Hailfinger2009-05-161-12/+12
| | | | | | | | | | | | | | | | | | | Use chipaddr instead of volatile uint8_t * because when we access chips in external flashers, they are not accessed via pointers at all. Benefits: This allows us to differentiate between volatile machine memory accesses and flash chip accesses. It also enforces usage of chip_{read,write}[bwl] to access flash chips, so nobody will unintentionally use pointers to access chips anymore. Some unneeded casts are removed as well. Grepping for chip operations and machine memory operations doesn't yield any false positives anymore. Compile tested on 32 bit and 64 bit Linux. Corresponding to flashrom svn r519.

* Use helper functions to access flash chipsCarl-Daniel Hailfinger2009-03-051-28/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
