  kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT

kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT

2011-01-21T01:02:05+00:00

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

tty: move drivers/serial/ to drivers/tty/serial/

2011-01-13T20:10:18+00:00

The serial drivers are really just tty drivers, so move them to
drivers/tty/ to make things a bit neater overall.

This is part of the tty/serial driver movement proceedure as proposed by
Arnd Bergmann and approved by everyone involved a number of months ago.

cs5535: deprecate older cs5535_gpio driver

2011-01-13T16:03:13+00:00

The newer drivers/gpio/cs5535-gpio.c replaces drivers/misc/cs5535_gpio.c.
The new driver has been in the tree for a little while, and has received
some testing; it's time to mark the old one as deprecated.  I'm thinking
removal around 2.6.40 would be good, provided we're not missing critical
functionality in the newer driver.

drivers: char: hvc: add arm JTAG DCC console support

2010-12-01T01:27:13+00:00

This driver adds a basic console that uses the arm JTAG
DCC to transfer data back and forth. It has support for
ARMv6 and ARMv7.

This console is created under the HVC driver, and should be named
/dev/hvcX (or /dev/hvc0 for example).

add ttyprintk driver

2010-10-22T17:20:02+00:00

Ttyprintk is a pseudo TTY driver, which allows users to make printk
messages, via output to ttyprintk device. It is possible to store
"console" messages inline with kernel messages for better analyses of
the boot process, for example.

pc8736x_gpio: depends on X86_32

2010-08-12T15:43:29+00:00

Fix kconfig dependency warning for PC8736x_GPIO by restricting it to
X86_32.

  warning: (SCx200_GPIO && SCx200 || PC8736x_GPIO && X86) selects NSC_GPIO which has unmet direct dependencies (X86_32)

NSC_GPIO is X86_32 only.  The other driver (SCx200_GPIO) that selects
NSC_GPIO is X86_32 only (indirectly, since SCx200 depends on X86_32), so
limit this driver also.

ramoops: add HAS_IOMEM dependency

2010-06-04T22:21:44+00:00

The driver fails to compile on s390:

drivers/char/ramoops.c: In function 'ramoops_init':
drivers/char/ramoops.c:122: error: implicit declaration of function 'ioremap'

Since we won't make use of the driver anyway on s390 just let it depend on
HAS_IOMEM.

char drivers: RAM oops/panic logger

2010-05-27T16:12:50+00:00

Ramoops, like mtdoops, can log oops/panic information but in RAM.  It can
be used with persistent RAM for systems without flash support.  In
addition, for this systems, with this driver, it's no more needed add to
the kernel the mtd subsystem with advantage in footprint.

It can be used in a very easy way with persistent RAM for systems without
flash support.  For these systems, with this driver, it is no longer
required to cinlude mtd subsystem with an advantage in footprint.  In
addition, you can save flash space and store this information only in RAM.
