[PATCH v2 1/4] powerpc: wii_defconfig: Disable Ethernet driver support code

[PATCH v2 1/4] powerpc: wii_defconfig: Disable Ethernet driver support code

[Jonathan Neuschäfer]

The Wii doesn't have built-in Ethernet and USB Ethernet adapters are in
a different menu. Disable CONFIG_ETHERNET to save some space in support
code for Ethernet drivers.

Note that this patch doesn't disable any Ethernet drivers, because they
are not enabled by default.

[PATCH v2 2/4] powerpc: wii_defconfig: Enable GPIO-related options

[Jonathan Neuschäfer]

Now that there's a GPIO driver for the Wii, let's enable the following
drivers:

- the GPIO driver itself
- gpio-keys
- gpio-poweroff
- gpio-leds and a few LED triggers

Signed-off-by: Jonathan Neuschäfer <j.neuschaefer@gmx.net>

v2:
- Set CONFIG_NEW_LEDS=y and CONFIG_LEDS_TRIGGERS=y, without which some
  of the other options can't be set.

[PATCH v2 3/4] powerpc: wii_defconfig: Enable Wii SDHCI driver

[Jonathan Neuschäfer]

This allows access to the SD card and the BCM4318 Wifi module.

Note that until some fixes in the interrupt controller drivers used on
the Wii, the SDHCI controllers will not be usable.

[PATCH v2 4/4] powerpc: wii_defconfig: Disable BCMA support

[Jonathan Neuschäfer]

The B43 driver only needs CONFIG_SSB to support the WLAN card found in
the Wii. Configure it accordingly, and disable BCMA bus support to save
a bit of space.

I forgot to CC the right set of people/mailing lists on the cover
