This is initial code written by Davide Ferri for the PCTV 340e, including
a new xc4000 driver. I am checking in all the code unmodified, and making
no assertions about its quality (other than confirming it compiles).

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.

Tuner, DVB frontend and video helper chip drivers are by default
autoselected by their respective host cards, this, however, doesn't make
much sense on SoC-based systems. Disable autoselection on EMBEDDED

There are several Kconfig items using CUSTOMIZE. Yet, most use the English
writing CUSTOMISE. This generates lots of trouble, because people sometimes type
the Kbuild item different.
Let's standardise every occurrence using the same syntax.
The changes were generated by this small shell script:
for i in `find linux -type f`; do sed s,CUSTOMIZE,CUSTOMISE,g $i >/tmp/a && mv /tmp/a $i; done

The build option, MEDIA_TUNER_CUSTOMIZE, allows us to disable tuner drivers
that would have otherwise been selected by default. This is an advanced
customization option that should be disabled by default.

-tip testing found the following build failure:
LD .tmp_vmlinux1
drivers/built-in.o: In function `generic_set_freq':
tuner-xc2028.c:(.text+0xbd896): undefined reference to `request_firmware'

with this config:
http://redhat.com/~mingo/misc/config-Tue_May_20_18_11_34_CEST_2008.bad
the reason is another kconfig tool bug that has to be worked around in
the driver's Kconfig file: if FW_LOADER is selected in a second
dependency, that is not properly propagated up the dependencies.
in this case, FW_LOADER is selected from MEDIA_TUNER_XC2028:
config MEDIA_TUNER_XC2028
tristate "XCeive xc2028/xc3028 tuners"
depends on VIDEO_MEDIA && I2C
depends on HOTPLUG
select FW_LOADER
which got selected by MEDIA_TUNER:
config MEDIA_TUNER
tristate
default VIDEO_MEDIA && I2C
depends on VIDEO_MEDIA && I2C
select FW_LOADER if !MEDIA_TUNER_CUSTOMIZE && HOTPLUG
but the kconfig tool did not pick up this second-order dependency and
allowed CONFIG_FW_LOADER=m to be selected - in which case the build
fails.
the workaround i found was to move the select of FW_LOADER one level up,
so that the buggy kconfig tool can notice it and can act appropriately.
This problem can probably be worked around in other ways as well, i went
for the minimal fix.
Obviously, the kconfig tool should be fixed, it is not reasonable to
expect driver authors to do manual dependency resolution (that kconfig
itself already does) and uglify the Kconfig files. The kconfig tool did
nothing to warn about this situation and did not prevent this faulty
.config from being constructed.

- MEDIA_ATTACH now applies also for V4L;
- select a FW_LOADER dependent driver should happen only if HOTPLUG;
- apply the common tuner dependency to all tuners. This helps to avoid latter
issues.

Since:
1) FW_LOADER is defined as:
config FW_LOADER
tristate "Userspace firmware loading support"
depends on HOTPLUG
2) several V4L/DVB driver just selects it;
3) select is not smart enough to auto-select HOTPLUG, if select FW_LOADER.
So, All drivers that select FW_LOADER should also depend on HOTPLUG.
An easier solution (for the end-user perspective) would be to "select HOTPLUG".
However, live is not simple. This would cause recursive dependency issues like
this one:
drivers/usb/Kconfig:62:error: found recursive dependency: USB -> USB_OHCI_HCD
-> I2C -> MEDIA_TUNER -> MEDIA_TUNER_XC2028 -> HOTPLUG -> PCCARD -> PCMCIA ->
USB_ARCH_HAS_HCD -> MOUSE_APPLETOUCH -> USB

em28xx-dvb doesn't need FW_LOADER. Instead, tuner-xc2028 needs to select
FW_LOADER.
Also, this can happen only if HOTPLUG is selected, since FW_LOADER
is dependent on HOTPLUG.

Since all tuners are dependent of I2C, move I2C dependency to MEDIA_TUNER.
Also, simplifies the dependencies for the other Kconfig items.

Those tuners are currently used only under media/dvb. However,
they can support also analog TV. Better to move them to the same place
as the other hybrid tuners. This would make easier to use those tuners also
by analog drivers.

There were several issues in the past, caused by the hybrid tuner design, since
now, the same tuner can be used by drivers/media/dvb and drivers/media/video.
Kconfig items were rearranged, to split V4L/DVB core from their drivers.
