arch/tile: add hypervisor-based character driver for SPI flash ROM

2011-06-10T17:07:48+00:00

The first version of this patch proposed an arch/tile/drivers/ directory,
but the consensus was that this was probably a poor choice for a place to
group Tilera-specific drivers, and that in any case grouping by platform
was discouraged, and grouping by function was preferred.

This version of the patch addresses various issues raised in the
community, primarily the absence of sysfs integration.  The sysfs
integration now handles passing information on sector size, page size,
and total partition size to userspace as well.  In addition, we now
use a single "struct cdev" to manage all the partition minor devices,
and dynamically discover the correct number of partitions from the
hypervisor rather than using a module_param with a default value.

This driver has no particular "peer" drivers it can be grouped with.
It is sort of like an MTD driver for SPI ROM, but it doesn't group well
with the other MTD devices since it relies on hypervisor virtualization
to handle many of the irritating aspects of flash ROM management: sector
awareness, background read for sub-sector writes, bit examination to
determine whether a sector erase needs to be issued, etc.  It is in fact
more like an EEPROM driver, but the hypervisor virtualization does require
a "flush" command if you wish to commit a sector write prior to writing
to a different sector, and this is sufficiently different from generic
I2C/SPI EEPROMs that as a result it doesn't group well with them either.

The simple character device is already in use by a range of Tilera
SPI ROM management tools, as well as by customers.  In addition, using
the simple character device actually simplifies the userspace tools,
since they don't need to manage sector erase, background read, etc.
This both simplifies the code (since we can uniformly manage plain files
and the SPI ROM) as well as makes the user code portable to non-Linux
platforms that don't offer the same MTD ioctls.

Allow setting of number of raw devices as a module parameter

2011-05-07T00:52:31+00:00

Allow setting of maximal number of raw devices as a module parameter. This
requires changing of static array into a vmalloced one (the array is going to
be too large for kmalloc).

tty: move obsolete and broken generic_serial drivers to drivers/staging/generic_serial/

2011-02-23T01:09:33+00:00

As planned by Arnd Bergmann, this moves the following drivers to the
drivers/staging/generic_serial directory where they will be removed
after 2.6.41 if no one steps up to claim them.

tty: move Kconfig entries into drivers/tty from drivers/char

2011-02-22T23:41:47+00:00

The Kconfig options for the drivers/tty/ files still were hanging around
in the "big" drivers/char/Kconfig file, so move them to the proper
location under drivers/tty and drivers/tty/hvc/

hvc: add Blackfin JTAG console support

2011-02-17T19:12:40+00:00

This converts the existing bfin_jtag_comm TTY driver to the HVC layer so
that the common HVC code can worry about all of the TTY/polling crap and
leave the Blackfin code to worry about the Blackfin bits.
