m68k: Multi-platform EARLY_PRINTK

2014-05-28T08:10:04+00:00

Make the boot console available to more m68k platforms by leveraging
the head.S debug console.

The boot console is enabled by the "earlyprintk" command line argument
which is how most other architectures do this.

This is a change of behaviour for the Mac but does not negatively impact
the common use-case which is not debugging.

This is also a change of behaviour for other platforms because it means
the serial port stays quiet when CONFIG_EARLY_PRINTK is not enabled. This
is also an improvement for the common use-case.

m68k: Add support to export bootinfo in procfs

2013-12-08T10:01:48+00:00

Add optional support to export the bootinfo used to boot the kernel in a
"bootinfo" file in procfs.  This is useful with kexec.

This is based on the similar feature for ATAGS on ARM.

m68k: Sort out !CONFIG_MMU_SUN3 vs. CONFIG_HAS_DMA

2013-02-09T13:23:36+00:00

In two places, we check !CONFIG_MMU_SUN3 while we should check
CONFIG_HAS_DMA instead.
While fixing this, the check in  became redundant
( already handles this case), so just remove it.

m68k: common PCI support definitions and code

2012-07-17T05:49:41+00:00

Basic set of definitions and support code required to turn on CONFIG_PCI
for the m68k architecture. Nothing specific to any PCI implementation in
any m68k class CPU hardware yet.

m68k: Use generic init_task

2012-05-05T11:00:23+00:00

Same code. Use the generic version.

m68k: do not use m68k startup or interrupt code for ColdFire CPUs

2011-12-30T00:20:48+00:00

The ColdFire CPUs have their own startup and interrupt code (in the
platform/coldfire directory), and do not use the general m68k startup and
interrupt code. In fact the use of the arch/m68k/kernel/head.o is not about
CONFIG_MMU or not, it is really about the machine type we are compiling for.

Modify the selection and use of head.o to be based on the machine type.
Only select the local ints.o and vectors.o code if we are using the classic
68k CPU types (that use the conventional Morotola MMU or SUN3 MMU).

m68k: merge the init_task code for mmu and non-mmu targets

2011-12-24T11:47:56+00:00

The init_task code can be the same for both mmu and non-mmu targets.
None of the alignment carried out in the the current init_task code
is necessary. The linker script takes care of aligning the init_thread
structure to a THREAD SIZE boundary, and that is all we need.

So use the init_task.c code for all target types, that makes m68k
code consistent with what most other architectures do.
