* Flashrom only checks for very few chips if the erase workedCarl-Daniel Hailfinger2009-06-151-2/+17
| | | | | | | | | | | | | | | | | | | 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. Uwe successfully tested LPC on an CK804 box and SPI on some SB600 box. Corresponding to flashrom svn r595.

* Eliminate all 'inline's from the flashrom codeUwe Hermann2009-05-161-6/+3
| | | | | | | | | | | They serve pretty much no purpose, compilers can optimize pretty much all of what we might mark as inline anyway, _and_ inlines are not enforced in any way by the compiler either. They're totally unneeded. Kill them. Corresponding to flashrom svn r522. Signed-off-by: Uwe Hermann <uwe@hermann-uwe.de> Acked-by: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006@gmx.net>

* Use chipaddr instead of volatile uint8_t * because when we access chips in ↵Carl-Daniel Hailfinger2009-05-161-8/+7
| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | Before we attempt trickery, we can simply rename the accessor functions. Patch created with the help of Coccinelle. Corresponding to flashrom svn r420 and coreboot v2 svn r3984.

* Use helper functions to access flash chipsCarl-Daniel Hailfinger2009-03-051-22/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
