bcm47xx: remove support for kernel 4.14
We currently support three kernel versions on this target, let's just get rid of the oldest one. Cc: Rafał Miłecki <rafal@milecki.pl> Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>

Subject: [PATCH] MIPS: BCM47XX: Add Luxul XAP1500/XWR1750 WiFi LEDs
 | 
					 | 
				
			||||||
 | 
					 | 
				
			||||||
Some Luxul devices use PCIe connected GPIO LEDs that are not available
 | 
					 | 
				
			||||||
until the PCI subsytem and its drivers load. Using the same array for
 | 
					 | 
				
			||||||
these LEDs would block registering any LEDs until all GPIOs become
 | 
					 | 
				
			||||||
available. This may be undesired behavior as some LEDs should be
 | 
					 | 
				
			||||||
available as early as possible (e.g. system status LED). This patch will
 | 
					 | 
				
			||||||
allow registering available LEDs while deferring these PCIe GPIO
 | 
					 | 
				
			||||||
connected 'extra' LEDs until they become available.

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.

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.

able to use USB devices on his WNDR3400v2 device after the boot, until

he turns on GPIO #21 manually through sysfs.

On ASUS WL-500gP there are some "Data bus error"s when executing simple

commands liks "ps" or "cat /proc/1/cmdline".
 | 
					 |

These are standard probing messages when using pdc202xx_old:

With the default MAX_HWIFS value after above we get:

As you can see it's ide2 + ide3 and hde.
 | 
					 |

If SoC has a CardBus we can set resources of device at slot 1 only. It's
 | 
					 | 
				
			||||||
impossigle to set bridge resources as it simply overwrites device 1
 | 
					 | 
				
			||||||
configuration and usually results in Data bus error-s.
