* Simplify calls to inner write functionsCarl-Daniel Hailfinger2010-10-101-13/+0

* Unify chip write functionsCarl-Daniel Hailfinger2010-10-101-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Remove progress printing from individual flash chip driversCarl-Daniel Hailfinger2010-10-081-6/+0
| | | | | | | | | | Progress printing should be handled in the generic code, and will end up there once partial write is possible. Corresponding to flashrom svn r1207. Signed-off-by: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006@gmx.net> Acked-by: Sean Nelson <audiohacked@gmail.com>
* Move implicit erase out of chip driversCarl-Daniel Hailfinger2010-10-081-4/+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.

| | | | | | | | | | | | | | | Unistd.h was only used to get a definition of NULL in all files. Add our own NULL #define and remove unistd.h from flash.h stdio.h has no place in flash.h, it should be included only in files which really need it. Add #include statements in individual .c files where needed. Replace a few printf with msg_* to eliminate the need for stdio.h. Corresponding to flashrom svn r1021.

* Refine support for the JEDEC Software Data ProtectionMichael Karcher2009-11-261-1/+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.

* Standardize on using __func__ instead of __FUNCTION__Uwe Hermann2009-09-021-1/+1
| | | | | | | | | | | | | | | 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.

* Flashrom only checks for very few chips if the erase workedCarl-Daniel Hailfinger2009-06-151-4/+10
| | | | | | | | | | | | | | | | | | | And even when it checks if the erase worked, the result of that check is often ignored. Convert all erase functions and actually check return codes almost everywhere. Check inside all erase_* routines if erase worked, not outside. erase_sector_jedec and erase_block_jedec have changed prototypes to enable erase checking.

* Introduce a type "chipaddr" to abstract the offsets within flash regionsCarl-Daniel Hailfinger2009-05-161-9/+9
| | | | | | | | | | | | | | | | | | | 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 Hailfinger2009-03-051-29/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
