Add support for two new winbond SPI flash parts.

The 8devices carambola 2 board uses the 16MB part. Here's how it looks: spibus0: on spi0 mx25l0: at cs 0 on spibus0 mx25l0: w25q128, sector 65536 bytes, 256 sectors Tested: * 8devices Carambola 2 board

Remove duplicate const specifiers in many drivers (I hope I got all of

them, please let me know if not). Most of these are of the form: static const struct bzzt_type { [...list of members...] } const bzzt_devs[] = { [...list of initializers...] }; The second const is unnecessary, as arrays cannot be modified anyway, and if the elements are const, the whole thing is const automatically (e.g. it is placed in .rodata). I have verified this does not change the binary output of a full kernel build (except for build timestamps embedded in the object files). Reviewed by: yongari, marius MFC after: 1 week

Revert r236529, re-enabling verification of the flashed content as

the underlying problem was dealt with in r237239 (in fact, disabling verification also actually only made the problem less likely to occur).

Disable verification of the flashed content for now; for reasons unknown

- Make the device description match the driver name. - Identify the chip variant based on the JEDEC and use that information to use the proper values for page count, offset and size instead of hardcoding a AT45DB642x with 2^N byte page support disabled. - Take advantage of bioq_takefirst(). - Given that CONTINUOUS_ARRAY_READ_HF (0x0b) command isn't even mentioned in Atmel's DataFlash Application Note, as suggested by the previous comment may not work on all all devices and actually doesn't properly on at least AT45DB321D (JEDEC 0x1f2701), rewrite at45d_task() to use CONTINUOUS_ARRAY_READ (0xe8) for reading instead. This rewrite is laid out in a way allowing to easily add support for BIO_DELETE later on. - Add support for reads and writes not starting on a page boundary. - Verify the flash content after writing. - Let at45d_task() gracefully handle errors on SPI transfers and the device not becoming ready afterwards again. [1] - Use DEVMETHOD_END. [1] - Use NULL instead of 0 for pointers. [1] Additional testing by: Ian Lepore Submitted by: Ian Lepore [1] MFC after: 1 week

Modify the spi flash driver to allow smaller read IO sizes, but enforce

2011-02-16T20:07:44Z

the larger, aligned write+erase sizes the driver currently implements. This preserves write behaviour but makes the flash driver usable for things like a read-only FFS or a geom_uzip/geom_compress . Note that since GEOM will now return the sector size as being smaller, writes of sector size/alignment will now fail with an EIO. Code which writes to the flash device will have to be (for now) manually taught about the flash write blocksize.
