ARM: berlin: do not select RESET_CONTROLLER

2014-11-18T19:27:53+00:00

RESET_CONTROLLER is meant to be user-selectable. To respect that,
do not select it automatically when using ARCH_BERLIN.

ARM: Berlin: select the reset controller

2014-10-21T09:35:15+00:00

The Marvell Berlin SoCs now has a reset controller. Add the needed
configuration. While at it reorder Kconfigs alphabetically.

ARM: use menuconfig for sub-arch menus

2014-06-17T15:09:48+00:00

The System Type menu is getting quite long with platforms and is
inconsistent in handling of sub-arch specific options. Tidy up the menu
by making platform options a menuconfig entry containing any platform
specific config items.

ARM: berlin: add SMP support

2014-06-16T11:16:44+00:00

Adds SMP support for Berlin SoCs. Secondary CPUs are reset, then
execute the instruction we put in the reset exception register, setting
the pc at the address contained in the software reset address register,
which is the physical address of the Berlin secondary startup.

This implementation avoid using the pen lock mechanism.

Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm into next

2014-06-05T22:57:04+00:00

Pull ARM updates from Russell King:

 - Major clean-up of the L2 cache support code.  The existing mess was
   becoming rather unmaintainable through all the additions that others
   have done over time.  This turns it into a much nicer structure, and
   implements a few performance improvements as well.

 - Clean up some of the CP15 control register tweaks for alignment
   support, moving some code and data into alignment.c

 - DMA properties for ARM, from Santosh and reviewed by DT people.  This
   adds DT properties to specify bus translations we can't discover
   automatically, and to indicate whether devices are coherent.

 - Hibernation support for ARM

 - Make ftrace work with read-only text in modules

 - add suspend support for PJ4B CPUs

 - rework interrupt masking for undefined instruction handling, which
   allows us to enable interrupts earlier in the handling of these
   exceptions.

 - support for big endian page tables

 - fix stacktrace support to exclude stacktrace functions from the
   trace, and add save_stack_trace_regs() implementation so that kprobes
   can record stack traces.

 - Add support for the Cortex-A17 CPU.

 - Remove last vestiges of ARM710 support.

 - Removal of ARM "meminfo" structure, finally converting us solely to
   memblock to handle the early memory initialisation.

ARM: l2c: berlin: convert to generic l2c OF initialisation

2014-05-29T23:49:06+00:00

Remove the explicit call to l2x0_of_init(), converting to the generic
infrastructure instead.  We can remove the explicit machine init too
as this becomes identical to the generic version.

ARM: l2c: remove platforms/SoCs setting early BRESP

2014-05-29T23:48:51+00:00

Since we now automatically enable early BRESP in core L2C-310 code when
we detect a Cortex-A9, we don't need platforms/SoCs to set this bit
explicitly.  Instead, they should seek to preserve the value of bit 30
in the auxiliary control register.
