Adrian Chadd 917721a495 Modify the spi flash driver to allow smaller read IO sizes, but enforce
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.

Adrian Chadd a565668bc5 Add support for the m25p64; lifted straight from Linux.
This flash chip is found on the Ubiquiti LS-SR71 board.
I've successfully tested reading; I've not tried writing to it yet.

Adrian Chadd a122fea4ff Add s25sl064a, an 8mb SPI flash part. 2010-08-17 16:27:13 +00:00
Adrian Chadd 62c3a412df Fix naming to be consistent. 2010-07-19 21:50:43 +00:00
Adrian Chadd 53436ace02 Extend the mx25l erase function to support different erase commands. 2010-07-19 21:46:40 +00:00
Adrian Chadd d2cf1fd5e4 Extend the mx25l flash device support to include a set of per-device
flags.

Some of these parts will support 4K/32K block erases rather than
a sector erase. This includes (at least) the MX25L128.

Adrian Chadd dddd00f6a4 Include 4k/32k erase commands.
These were sourced from the MX25L128 datasheet and match up
with what is used in Linux mtd/devices/m25p80.c .

Add a FreeBSD keyword whilst I'm here.

Warner Losh 0d633f654d o Move the driveid.h file
o lots of tweaks to header paths.
o comment out SMP for the moment

# we now make it through the .c make depend, the .s needs more work.

Warner Losh d0b7b80503 Part of the cf driver missed. 2009-06-14 04:16:58 +00:00
Warner Losh b02713c7a4 Move dev/flash/ cf driver into octeon dir where it belongs. 2009-06-14 03:55:27 +00:00
Warner Losh 5be117dfac Merge in Cavium's CF driver. This too is in the wrong place and will
be moved.

Oleksandr Tymoshenko ab88d607a5 - Remove nonexistent header file from includes list 2009-05-13 18:31:28 +00:00
Julian Elischer 3745c395ec Rename the kthread_xxx (e.g. kthread_create()) calls
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.

Warner Losh 674a914028 MFp4:
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.
