* Make all internal routines return an int error status, and check theIan Lepore2018-03-181-41/+47
| | | | | | | | status at all call points. Combine the get_status and wait_for_ready routines, since waiting for ready is the only reason to ever get status. Notes: svn path=/head/; revision=331138

* Bugfix: wait for writes/erases to complete after starting them, instead ofIan Lepore2018-03-181-1/+2
| | | | | | | | | | | | | | | before starting them. Using the wait-before logic would make sense if there was useful time- consuming work that could be done between the end of one write and the beginning of the next, but it also requires doing the wait-for-ready before reading, because a prior write or erase could still be in progress. Reading is the far more common case, so adding a whole extra bus transaction to check for ready before each read would soak up any small gains that might be had from doing async writes.

| | | | | | | | | for the same condition that the preceeding lines checked for and would have returned EIO, so the assert could never possibly trigger (sc_sectorsize must inherently be an integer multiple of FLASH_PAGE_SIZE). Notes: svn path=/head/; revision=331126
* Do not overwrite the contents of BIO_WRITE buffers. SPI inherentlyIan Lepore2018-03-181-1/+2
| | | | | | | | | | transfers data in both directions at once. When writing to the device, use a dummy buffer for the incoming data, not the same buffer as the outgoing data. Writes are done in FLASH_PAGE_SIZE chunks, which is only 256 bytes, so just put the dummy buffer into the softc. Notes: svn path=/head/; revision=331123

* sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-273-0/+6
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326255

* Enable 4-byte address support for the mx25l family of SPI flash devices.Stanislav Galabov2016-04-042-18/+93
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce 2 new flags: - FL_ENABLE_4B_ADDR (forces the use of 4-byte addresses) - FL_DISABLE_4B_ADDR (forces the use of 3-byte addresses) If an SPI flash chip is defined with FL_ENABLE_4B_ADDR in its flags, then an 'Enter 4-byte mode' command is sent to the chip at attach time and, later, all commands that require addressing are issued with 4-byte addresses. If an SPI flash chip is defined with FL_DISABLE_4B_ADDR in its flags, then an 'Exit 4-byte mode' command is sent to the chip at attach time and, later, all commands that require addressing are issued with 3-byte addresses. For chips that do not have any of these flags defined the behaviour is unchanged. This change also adds support for the MX25L25735F and MX25L25635E chips (vendor id 0xc2, device id 0x2019), which support 4-byte mode and enables 4-byte mode for them. These are 256Mbit devices (32MiB) and, as such, can only be fully addressed by using 4-byte addresses.

* [flash] Teach mx25l SPI flash driver to interact with fdt_slicer and ↵Adrian Chadd2016-01-221-0/+23
| | | | | | | | | | | | | | | | | | | | | geom_flashmap This teaches the mx25l driver (sys/dev/flash/mx25l.c) to interact with sys/dev/fdt/fdt_slicer.c and sys/geom/geom_flashmap.c. This allows systems with SPI flash to benefit from the possibility to define flash 'slices' via FDT, just the same way that it's currently possible for CFI and NAND flashes.

| | | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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.

* 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
