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/atari: Call paging_init() before nf_init()

2013-11-26T10:09:23+00:00

nf_init() uses virt_to_phys(), which depends on m68k_memoffset being set and
module_fixup() having been called, but this is only done in paging_init().
Hence call paging_init() before nf_init().

This went unnoticed, as virt_to_phys() is a no-op on Atari, unless you start
fiddling with the memory blocks in the bootinfo manually.

m68k/UAPI: Move generic definitions to

2013-11-26T10:09:16+00:00

Move generic definitions used by bootstraps to uapi/asm/bootinfo.h:
  - Machine types,
  - CPU, FPU, and MMU types,
  - struct mem_info.

Keep a copy of struct mem_info for in-kernel use, and rename it to struct
m68k_mem_info, as the exported one will be modified later.

m68k: The bootinfo is located right after the kernel

2013-11-26T10:09:11+00:00

Since the introduction of init sections (which are located after BSS), the
bootinfo is no longer located right after the BSS, but after all kernel
sections.

m68k: Mark functions only called from setup_arch() __init

2013-11-26T10:08:54+00:00

Some functions that are only called (indirectly) from setup_arch() lack
__init annotations.

m68k/atari: ROM port ISA adapter support

2013-04-16T19:08:11+00:00

Atari ROM port ISA adapter support for EtherNEC and NetUSBee adapters

16 bit access for ROM port adapters follows debugging and
clarification by David Galvez . The NetUSBee
ISP1160 USB chip uses these macros.

m68k: set arch_gettimeoffset directly

2012-12-24T16:36:34+00:00

remove m68k's mach_gettimeoffset function pointer, and instead directly
set the arch_gettimeoffset function pointer. This requires multiplying
all function results by 1000, since the removed m68k_gettimeoffset() did
this. Also, s/unsigned long/u32/ just to make the function prototypes
exactly match that of arch_gettimeoffset.

m68k: add ColdFire FPU support for the V4e ColdFire CPUs

2011-12-30T00:20:47+00:00

The V4e ColdFire CPU family also has an integrated FPU (as well as the MMU).
So add code to support this hardware along side the existing m68k FPU code.

The ColdFire FPU is of course different to all previous 68k FP units. It is
close in operation to the 68060, but not completely compatible. The biggest
issue to deal with is that the ColdFire FPU multi-move instructions are
different. It does not support multi-moving the FP control registers, and
the multi-move of the FP data registers uses a different instruction
mnemonic.
