MIPS: tools: Fix relocs tool compiler warnings

2016-08-03T07:00:55+00:00

When using clang as HOSTCC, the following warnings appear:

Fix them by making Elf64_Mips_Rela a union

MIPS: Octeon: Delete built-in DTB pruning code for D-Link DSR-1000N.

2016-08-02T12:00:16+00:00

Users will get more complete functionality by using the appended DTB,
so delete the legacy booting support for this board.

MIPS: ZBOOT: copy appended dtb to the end of the kernel

2016-08-02T12:00:16+00:00

Instead of rewriting the arguments, just move the appended dtb to where
the decompressed kernel expects it. This eliminates the need for special
casing vmlinuz.bin appended dtb files.

MIPS: devicetree: fix cpu interrupt controller node-names

2016-05-28T10:35:12+00:00

Here is the quote from [1]:

    The unit-address must match the first address specified
    in the reg property of the node. If the node has no reg property,
    the @ and unit-address must be omitted and the node-name alone
    differentiates the node from other nodes at the same level

This patch adjusts MIPS dts-files and devicetree binding
documentation in accordance with [1].

MIPS: JZ4740: Probe OHCI platform device via DT

2016-05-13T17:09:24+00:00

The DT fragment will select the ohci-platform driver, since that can
handle the JZ4740 OHCI just fine. While I don't have a JZ4740-based
board with anything connected to the USB host controller, I did test
the generic OHCI driver successfully on a JZ4770-based board.

The device is disabled by default; boards that want to use it can
override the "status" property. The mass-production Qi LB60 boards
don't use the USB host controller.

MIPS: BMIPS: Adjust mips-hpt-frequency for BCM7435

2016-05-13T15:44:53+00:00

The CPU actually runs at 1405Mhz which gives us a 175625000 Hz MIPS timer
frequency (CPU frequency / 8).

2016-05-13T12:02:10+00:00

- Remove unneeded leds0 alias.
- Switch to bcm6345-l1-intc interrupt controller.
- Use interrupt-controller instead of periph_intc and cpu_intc.
- Add uart1 node.
- Single ohci and ehci nodes.
- Avoid using underscores in node names.
- Rename uart aliases to serial.
- Remove blank line in cpus node.
