[PATCH 2/2] bmips: add device tree example for BCM6358

[Álvaro Fernández Rojas]

This adds a device tree example for SFR Neufbox4 (Sercomm version), which
also serves as a real example for brcm,bcm6358-leds.

Why do we need alias for LEDs?

You shouldn't need both here. Just stdout-path.

Okay, I will remove this, but you should know it was accepted for 
BCM6328 and BCM6368 too:

Okay, I will use stdout-path only, but once again you should know that 
both are used on every bmips board:

[PATCH v4 1/2] bmips: add BCM6358 support

[Álvaro Fernández Rojas]

BCM6358 has a shared TLB which conflicts with current SMP support, so it must
be disabled for now.
BCM6358 uses >= 0xfffe0000 addresses for internal registers, which need to be
remapped (by using a simplified version of BRCM63xx ioremap.h).
However, 0xfff80000 is a better address, since it also covers BCM3368, leaving
the possibility to add it in the future.

Signed-off-by: Álvaro Fernández Rojas <noltari@gmail.com>

 v4: no changes, resend
 v3: Use a hardcoded constant for is_bmips_internal_registers (BCM3368 base
  address)
 v2: Use a different approach for remapping internal registers

[PATCH 2/2] bmips: add device tree example for BCM6358

[Álvaro Fernández Rojas]

This adds a device tree example for SFR Neufbox4 (Sercomm version), which
also serves as a real example for brcm,bcm6358-leds.

Signed-off-by: Álvaro Fernández Rojas <noltari@gmail.com>
---
 v5: more device tree improvements
  - There is just ohci/ehci node.
  - Avoid using underscores in node names.
  - Use interrupt-controller for cpu_intc.
  - Rename uart aliases to serial.
 v4: Device tree improvements:
  - Switch to native-endian for syscon.
  - Switch to bcm6345-l1-intc interrupt controller.
  - Add ehci and ohci nodes.
 v3: Device tree fixes
  - Use interrupt-controller instead of periph_intc.
  - Use led@# instead of naming the LEDs.
 v2: Remove led0 alias and use stdout-path only
