MIPS: implement device-tree handover to Linux kernel

2015-04-24T10:15:34+00:00

Add device-tree handover to Linux kernel conforming with MIPS UHI [1].
Register $a0 will be set to the reserved value -2. The address of
the device-tree blob will be stored as KSEG0 address in $a1. $a2 and
$a3 are set to zero.

MIPS: bootm: prepare a flattened device tree for the kernel

2015-01-21T13:02:49+00:00

Add the initial code to prepare a flattened device tree for
the kernel like relocating the FDT blob and fixing up the
/chosen and /memory nodes.

The final hand over to the kernel is not yet implemented. After
the community agreed on the MIPS boot interface for device trees,
the corresponding code will be added.

MIPS: bootm: add mem, rd_start and rd_size to kernel command line

2015-01-21T13:02:48+00:00

If the user wants to boot a kernel without legacy environment,
information like memory size, initrd address and size should be
handed over to the kernel in the command line.

MIPS: bootm: refactor preparation of Linux kernel environment

2015-01-21T13:02:48+00:00

Move preparation of Linux kernel environment in a separate
function and mark it as legacy. Add a Kconfig option to make
that legacy mode configurable.

MIPS: bootm: add missing initramfs relocation

2014-11-27T15:20:37+00:00

The initramfs is currently only relocated if the user calls
the bootm ramdisk subcommand. If bootm should be used without
subcommands, the arch-specific bootm code needs to implement
the relocation.

mips: don't hardcode Malta env baudrate

2013-11-26T20:49:17+00:00

The baudrate passed to Linux in the environment was hardcoded at 38400.
Instead pass the correct baudrate from global data, allowing Linux to
correctly inherit the baudrate used by U-boot when console setup is not
explicitly specified.

qemu-malta: rename to just "malta"

2013-11-09T16:21:01+00:00

This is in preparation for adapting this board to function correctly on
a physical MIPS Malta board. The board is moved into an "imgtec" vendor
directory at the same time in order to ready us for any other boards
supported by Imagination in the future.
