libfdt: Introduce new ARCH_FIXUP_FDT option

2016-08-01T01:37:08+00:00

Add new Kconfig option to disable arch_fixup_fdt() calls for cases where
U-Boot shouldn't update memory setup in DTB file.
One example of usage of this option is to boot OS with different memory
setup than U-Boot use.

MIPS: bootm: Add fixup of '/memory' node.

2016-04-19T11:21:48+00:00

MIPS arch do not update 'reg' property of /memory node.
As a result Linux bootup will not work unless board.dts
file contains right /memory offset-size information or
board implements required memory fixup.
Fixing by renaming (unused) _arch_fixup_memory_node_ to
_arch_fixup_fdt_ in arch/mips/lib/bootm.c inline with ARM arch.

MIPS: bootm: rework and fix broken bootm code

2015-11-06T12:27:28+00:00

The move to 'generic board' as well as changes in the generic
bootm code broke the boot of FIT uImage's. Especially uImage's
with additional initramfs images or FDT's do not work anymore.

Refactor the bootm code to work again with the generic bootm code.

Always relocate ramdisk and FDT in step 'bootm prep' because the
generic bootm code does this only for legacy uImage's.

Move the step 'bootm cmdline' to 'bootm prep' because the Linux
kernel parameters rd_start and rd_size have to be initialized after
the relocation of the ramdisk.

Furthermore support the step 'bootm fake'.

MIPS: fix syntax for fdt_chosen/initrd.

2015-08-21T13:22:41+00:00

The syntax for the fdt_chosen/initrd
functions seem to deprecated in usage
from MIPS bootm implementation.

Third parameter is no more used in these api's

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.
