Paul Gortmaker 605a46ee83 x86/platform: Make platform/geode/net5501.c explicitly non-modular
The Kconfig currently controlling compilation of this code is:

  arch/x86/Kconfig:config NET5501
  arch/x86/Kconfig:       bool "Soekris Engineering net5501 System Support (LEDS, GPIO, etc)"

...meaning that it currently is not being built as a module by anyone.

Lets remove the couple traces of modularity, so that when reading
the driver there is no doubt it is builtin-only.

Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

We replace module.h with moduleparam.h since the file does declare

easiest way to remain compatible with existing boot arg use cases.

Bjarke Istrup Pedersen d1d0589a56 arch/x86/platform/geode/net5501.c: change active_low to 0 for LED driver
It seems that there was an error with the active_low = 1 for the
LED, since it should be set to 0 (meaning that active is high,
since 0 is false, hence the confusion.

The wiki article about it confuses it, since it contradicts itself,
regarding what turns on the LED.

I have tested 3.4-rc2 on my net5501 with this patch, and it makes the LED
behave correctly, where "none" turns it off, and "default-on" turns it on,
when echoed onto the trigger "file" in /sys/class/leds.

Philip A. Prindeville 3197059af0 geos: Platform driver for Geos and Geos2 single-board computers.
Trivial platform driver for Traverse Technologies Geos and Geos2
single-board computers. Uses SMBIOS to identify platform.
Based on progressive revisions of the leds-net5501 driver that
was rewritten by Ed Wildgoose as a platform driver.

Supports GPIO-based LEDs (3) and 1 polled button which is
typically used for a soft reset.

Rusty Russell 476bc0015b module_param: make bool parameters really bool (arch)
module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.

Ed Wildgoose d4f3e35017 x86: geode: New PCEngines Alix system driver
This new driver replaces the old PCEngines Alix 2/3 LED driver with a
new driver that controls the LEDs through the leds-gpio driver. The
old driver accessed GPIOs directly, which created a conflict and
prevented also loading the cs5535-gpio driver to read other GPIOs on
the Alix board. With this new driver, we hook into leds-gpio which in
turn uses GPIO to control the LEDs and therefore it's possible to
control both the LEDs and access onboard GPIOs

Driver is moved to platform/geode as requested by Grant and any other
geode initialisation modules should move here also

This driver is inspired by leds-net5501.c by Alessandro Zummo.

Ideally, leds-net5501.c should also be moved to platform/geode. 
Additionally the driver relies on parts of the patch: 7f131cf3ed ("leds:
leds-alix2c - take port address from MSR) by Daniel Mack to perform
detection of the Alix board.
