mips: convert fdt pointers to opaque pointers

2014-04-30T05:59:13+00:00

The architecture code does not need to access the internals of the FDT
blob directly, so make the pointers to it void * and use char arrays
for section variables.

of: remove early_init_dt_setup_initrd_arch

2013-10-09T16:39:01+00:00

All arches do essentially the same thing now for
early_init_dt_setup_initrd_arch, so it can now be removed.

of: Specify initrd location using 64-bit

2013-07-24T10:10:01+00:00

On some PAE architectures, the entire range of physical memory could reside
outside the 32-bit limit.  These systems need the ability to specify the
initrd location using 64-bit numbers.

This patch globally modifies the early_init_dt_setup_initrd_arch() function to
use 64-bit numbers instead of the current unsigned long.

There has been quite a bit of debate about whether to use u64 or phys_addr_t.
It was concluded to stick to u64 to be consistent with rest of the device
tree code. As summarized by Geert, "The address to load the initrd is decided
by the bootloader/user and set at that point later in time. The dtb should not
be tied to the kernel you are booting"

MIPS: using strlcpy() instead of strncpy()

2013-06-10T16:01:26+00:00

Ensure strings are always '\0' terminated.  Or in the next pr_info() shit
may hit the fan.

MIPS: move mips_{set,get}_machine_name() to a more generic place

2013-05-07T23:19:07+00:00

Previously this functionality was only available to users of the mips_machine
api. Moving the code to prom.c allows us to also add a OF wrapper.

MIPS: Prune some target specific code out of prom.c

2012-07-23T12:54:52+00:00

This code is not common enough to be in a shared file.  It is also not
used by any existing boards, so just remove it.

[ralf@linux-mips.org: Dropped removal of irq_create_of_mapping which was
already removed by abd2363f6a5f1030b935e0bdc15cf917313b3b10
[irq_domain/mips: Allow irq_domain on MIPS].  Moved device_tree_init() and

MIPS: Add helper function to allow platforms to point at a DTB.

2012-05-15T15:49:19+00:00

Add __dt_setup_arch() that can be called to load a builtin DT.
Additionally we add a macro to allow loading a specific symbol
from the __dtb_* section.
