Subject: [PATCH] MIPS: BCM47XX: Add support for Netgear WNR1000 V3
This adds support for detecting this model board and registers some LEDs
and buttons.
There are two uncommon things regarding this device:
1) It can use two different "board_id" ID values.
Unit I have uses "U12H139T00_NETGEAR" value. This magic is also used
in firmware file header. There are two reports (one from an OpenWrt
user) of a different "U12H139T50_NETGEAR" magic though.
2) Power LEDs share GPIOs with buttons.
Amber one seems to share GPIO 2 with WPS button and green one seems
to share GPIO 3 with reset button. It remains unknown how to support
them and handle buttons at the same time. For that reason they aren't
added to the list of supported LEDs.

Subject: [PATCH] firmware: bcm47xx_nvram: support small (0x6000 B) NVRAM
partitions
Some old devices with 4 MiB flashes were using 0x1000 block size and
could use smaller (0x6000 bytes) flash partition for storing NVRAM
content. This adds support for reading NVRAM on Netgear WNR1000 V3.

Subject: [PATCH] MIPS: BCM47XX: Add support for Netgear WNR1000 V3
This adds support for detecting this model board and registers some LEDs
and buttons.
There are two uncommon things regarding this device:
1) It can use two different "board_id" ID values.
Unit I have uses "U12H139T00_NETGEAR" value. This magic is also used
in firmware file header. There are two reports (one from an OpenWrt
user) of a different "U12H139T50_NETGEAR" magic though.
2) Power LEDs share GPIOs with buttons.
Amber one seems to share GPIO 2 with WPS button and green one seems
to share GPIO 3 with reset button. It remains unknown how to support
them and handle buttons at the same time. For that reason they aren't
added to the list of supported LEDs.

Subject: [PATCH] firmware: bcm47xx_nvram: support small (0x6000 B) NVRAM
partitions
Some old devices with 4 MiB flashes were using 0x1000 block size and
could use smaller (0x6000 bytes) flash partition for storing NVRAM
content. This adds support for reading NVRAM on Netgear WNR1000 V3.
