Look up the LED from a GPIO machine descriptor table. The Geode LEDs
should be on the CS5535 companion chip.

These board files only use gpio_keys not gpio in general. This include is
just surplus, delete it.

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.

equal sign for the variable to be placed in the intended

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.

Add platform driver for the Soekris Engineering net5501 single-board
computer. Probes well-known locations in ROM for BIOS signature
to confirm correct platform. Registers 1 LED and 1 GPIO-based
button (typically used for soft reset).
