* MFC r242625:Dimitry Andric2012-11-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | - Loop up to 3 seconds when waiting for a device to get ready. [1] - 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] Notes: svn path=/stable/9/; revision=237384
* Modify the spi flash driver to allow smaller read IO sizes, but enforceAdrian Chadd2011-02-161-17/+18
| | | | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=218747

| | | | | | | | | | flags. Some of these parts will support 4K/32K block erases rather than a sector erase. This includes (at least) the MX25L128. Notes: svn path=/head/; revision=210262

* Rename the kthread_xxx (e.g. kthread_create()) callsJulian Elischer2007-10-201-1/+1
| | | | | | | | | | | | | | to kproc_xxx as they actually make whole processes. Thos makes way for us to add REAL kthread_create() and friends that actually make theads. it turns out that most of these calls actually end up being moved back to the thread version when it's added. but we need to make this cosmetic change first. I'd LOVE to do this rename in 7.0 so that we can eventually MFC the new kthread_xxx() calls. Notes: svn path=/head/; revision=172836

Preliminary support for Atmel AT45D series of DataFlash on the SPI bus (ok, not really a hardware bus, but a logical connection). This works only for the 8MB version of the part due to hard coding. Both read and write are supported. Notes: svn path=/head/; revision=164742
