0b660259e9 ARM: dts: BCM5301X: Don't use nonexistent "default-off" LED trigger
Such a trigger doesn't exist in Linux and is not needed as LED is being
turned off by default. This could cause errors in LEDs core code when
trying to set default trigger.

a252ccd3d2 ARM: dts: BCM5301X: Specify all RAM by including an extra block
The first 128 MiB of RAM can be accessed using an alias at address 0x0.

In theory we could access whole RAM using 0x80000000 - 0xbfffffff range
(up to 1 GiB) but it doesn't seem to work on Northstar. For some reason
(hardware setup left by the bootloader maybe?) 0x80000000 - 0x87ffffff
range can't be used. I reproduced this problem on:
1) Buffalo WZR-600DHP2 (BCM47081)
2) Netgear R6250 (BCM4708)
3) D-Link DIR-885L (BCM47094)

So it seems we're forced to access first 128 MiB using alias at 0x0 and
the rest using real base address + 128 MiB offset which is 0x88000000.

7b790d3b29 ARM: dts: BCM5301X: Enable UART by default for BCM4708(1), BCM4709(4) & BCM53012
Every device tested so far got UART0 (at 0x18000300) working as serial
console. It's most likely part of reference design and all vendors use
it that way.

It seems to be easier to enable it by default and just disable it if we
ever see a device with different hardware design.

5f79985dcf ARM: BCM5301X: Enable SPI-NOR on dual flash devices
Commit 1b47b98acc ("ARM: BCM5301X: Add DT entry for SPI controller and
NOR flash") enabled SPI-NOR device on routers using serial flash only.
However there are also devices with two flash memories:
1) Small SPI attached flash used mostly for booting
2) Bigger NAND used mostly for storing firmware
On such devices we still need SPI-NOR e.g. to access NVRAM data.

dd70ccfaa7 ARM: BCM5301X: Set vcc-gpio for USB controllers of few devices
There are few devices that have USB power controlled using GPIO. Linux
USB host driver (bcma-hcd) already supports this by reading vcc-gpio
from DT. Set it properly for all known devices.

0dfc7f6879 ARM: BCM5301X: Enable UART0 on tested devices
There are two possible UARTs so we have (both of) them disabled by
default. Override uart0 status on devices that were verified to use it.
In case of Netgear R6250 also drop an old (and invalid) overwrite. It
doesn't have uart1 connected.
