      ARM: STi: Remove platform call to trace_hardirqs_off() · 50de4dd4
      Peter Griffin authored 
      Calling trace_hardirqs_off() from the platform specific
secondary startup code as not been necessary since Dec 2010
when Russell King consolidated the call into the common SMP
code.

      ARM: STi: Add code to release secondary cores from holding pen. · 94a8cfce
      Peter Griffin authored 
      Most upstream devs boot STi platform via JTAG which abuses the
boot process by setting the PC of secondary cores directly. As
a consquence, booting STi platforms via u-boot results in only
the primary core being brought up as the code to manage the
holding pen is not upstream.

This patch adds the necessary code to bring the secondary cores
out of the holding pen. It uses the cpu-release-addr DT property
to get the address of the holding pen from the bootloader.

With this patch booting upstream kernels via u-boot works
correctly:

[    0.045456] CPU: Testing write buffer coherency: ok
[    0.045597] CPU0: thread -1, cpu 0, socket 0, mpidr 80000000
[    0.045734] Setting up static identity map for 0x40209000 - 0x40209098
[    0.065047] CPU1: thread -1, cpu 1, socket 0, mpidr 80000001

[    0.065089] SMP: Total of 2 processors activated (5983.43 BogoMIPS).
[    0.065092] CPU: All CPU(s) started in SVC mode.

      ARM: pxa: Use setup_timer · 6d6db340
      Vaishali Thakkar authored 
      Use the timer API function setup_timer instead of structure field
assignments to initialize a timer.

A simplified version of the Coccinelle semantic patch that performs
this transformation is as follows:

@change@
expression e1, e2, a;
@@

-init_timer(&e1);
+setup_timer(&e1, a, 0UL);
... when != a = e2
-e1.function = a;

      ARM: pxa: transition to dmaengine phase 1 · 4be0856f
      Robert Jarzmik authored 
      In order to slowly transition pxa to dmaengine, the legacy code will now
rely on dmaengine to request a channel.

This implies that PXA architecture selects DMADEVICES and PXA_DMA,
which is not pretty. Yet it enables PXA drivers to be ported one by one,
with part of them using dmaengine, and the other part using the legacy
code.
