mips: remove arch specific early_init_dt_alloc_memory_arch

2018-01-30T17:15:55+00:00

Now that the DT core code handles bootmem arches, we can remove the MIPS
specific early_init_dt_alloc_memory_arch function.

MIPS: Use early_init_fdt_reserve_self to protect DTB location

2017-01-03T15:34:45+00:00

early_init_fdt_reserve_self is used to tell the boot memory allocator
that a memory is occupied by the DTB, so add it in the MIPS init code to
ensure information about the DTB is added to the boot memory array.

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.
