* Add bus type annotation to struct flashchipsCarl-Daniel Hailfinger2009-05-311-14/+25
| | | | | | | | | | | | | | | | | | | Right now, the annotation only differentiates between SPI and non-SPI. Anyone who knows more about a specific flash chip should feel free to update it. The existing flashbus variable was abused to denote the SPI controller type. Use an aptly named variable for that purpose. Once this patch is merged, the chipset/programmer init functions can set supported flash chip types and flashrom can automatically select only matching probe/read/erase/write functions. A side benefit of that will be the elimination of the Winbond W29EE011 vs. AMIC A49LF040A conflict. Corresponding to flashrom svn r556.

* Use accessor functions for MMIOCarl-Daniel Hailfinger2009-05-171-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | Some MMIO accesses used volatile, others didn't (and risked non-execution of side effects) and even with volatile, some accesses looked dubious. Since the MMIO accessor functions and the onboard flash accessor functions are functionally identical (but have different signatures), make the flash accessors wrappers for the MMIO accessors. For some of the conversions, I used Coccinelle.

* Introduce a type "chipaddr" to abstract the offsets within flash regionsCarl-Daniel Hailfinger2009-05-161-52/+54
| | | | | | | | | | | | | | | | | | | 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.

ICH-style controllers exhibit this if SPI config is locked down. - The address in in a prohibited area.

Introduce separate error codes for unsupported opcode and prohibited address. Add the ability to adjust REMS and RES addresses to the minium supported read address with the help of spi_get_valid_read_addr().

* Use helper functions to access flash chipsCarl-Daniel Hailfinger2009-03-051-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
