MIPS: Fix build with CONFIG_OF=y for non OF-enabled targets

2015-08-03T07:25:00+00:00

Commit 01306aeadd75 ("MIPS: prepare for user enabling of CONFIG_OF")
changed the guards in asm/prom.h from CONFIG_OF to CONFIG_USE_OF, but
missed the actual function declarations in kernel/prom.c, which have
additional dependencies.

Fixes the following build error:

  CC      arch/mips/kernel/prom.o
arch/mips/kernel/prom.c: In function '__dt_setup_arch':
arch/mips/kernel/prom.c:54:2: error: implicit declaration of function 'early_init_dt_scan' [-Werror=implicit-function-declaration]
  if (!early_init_dt_scan(bph))
  ^

MIPS: prepare for user enabling of CONFIG_OF

2015-06-21T19:54:14+00:00

In preparation to allow users to enable DeviceTree without arch or
machine selecting it, we need to fix build errors on MIPS. When
CONFIG_OF is enabled, device_tree_init cannot be resolved. This is
trivially fixed by using CONFIG_USE_OF instead of CONFIG_OF for prom.h.

MIPS: Let __dt_register_buses accept a single bus type

2015-04-01T15:21:38+00:00

Some machines only have one bus type to register (e.g. "simple-bus").

MIPS: Create a helper function for DT setup

2014-11-24T06:45:12+00:00

A couple of platforms register two buses and call of_platform_populate().
Move this into a common function to reduce duplication.

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.
