m68k: Use get_signal() signal_setup_done()

2019-05-02T20:41:43+00:00

commit 0d97500d393012690f3579056629bea0369e6554 upstream.

Use the more generic functions get_signal() signal_setup_done()
for signal delivery.

m68k: Export mach_random_get_entropy to modules

m68k: Fix boot regression on machines with RAM at non-zero

2014-07-10T07:58:26+00:00

My enhancement to store the initial mapping size for later reuse in commit
486df8bc4627bdfc032d11bedcd056cc5343ee62 ("m68k: Increase initial mapping
to 8 or 16 MiB if possible") broke booting on machines where RAM doesn't
start at address zero.

Use pc-relative addressing to fix this.

Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu into next

2014-06-03T03:00:54+00:00

Pull m68knommu updates from Greg Ungerer:
 "Nothing too big, just a handfull of small changes.

  A couple of dragonball fixes, coldfire qspi cleanup and fixes, and
  some coldfire gpio cleanup, fixes and extensions"

* 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu:
  m68knommu: Implement gpio support for m54xx.
  m68knommu: Make everything thats not exported, static.
  m68knommu: setting the gpio data direction register to output doesn't dependent upon the value to output!
  m68knommu: add to_irq function so we can map gpios to external interrupts.
  m68knommu: qspi declutter.
  m68knommu: Fix the 5249/525x qspi base address.
  m68knommu: Add qspi clk for Coldfire SoCs without real clks.
  m68k: fix a compiler warning when building for DragonBall
  m68knommu: Fix mach_sched_init for EZ and VZ DragonBall chips

m68k: Increase initial mapping to 8 or 16 MiB if possible

2014-05-28T08:11:54+00:00

If the size of the first memory chunk is at least 8 or 16 MiB increase the
initial mapping to 8 resp. 16 MiB instead of 4 MiB.
This makes it possible to
  1. Map more memory in the first node without running out of space for the
     page tables,
  2. Boot kernels that don't fit in 4 MiB (e.g. multi_defconfig).

  - Add support for 8 MiB,
  - Store initial mapping size in head.S for later reuse,
  - Add comment about large kernels.

m68k/atari: fix SCC initialization for debug console

2014-05-28T08:11:53+00:00

Fix SCC initialization for Atari as was previously fixed for Mac. It's
probably not practical to share more code but some attempt is made to
align the Mac and Atari variants.

m68k/mvme16x: Adopt common boot console

2014-05-28T08:11:53+00:00

In a multi-platform kernel binary we only need one early console instance.

The difficulty here is that the common early console is started by
early_param(), whereas the MVME16x instance is started later by
config_mvme16x(). That means some interrupt setup must be done earlier.

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: Toward platform agnostic framebuffer debug logging

2014-05-26T20:41:25+00:00

Code subject to #ifdef CONSOLE is made more generic, as was apparently
intended by the original author.

Remove console_put_stats() routine. If it should be somehow useful, it
should also be useful on platforms without framebuffer debug logging. The
present implementation is only built #if defined CONFIG_MAC && defined
CONSOLE even though puts() works everywhere.
