…hotard/sti into next/soc
Merge "STi SoC changes for v4.8" from Patrice Chotard:
- Add a dummy L2 cache's write_sec callback as in non secure mode execution,
we can't get access to L2 cache secure registers
- Cosmetics change, in case of dump_stack, update the hardware name with a
more generic for the STi SoCs family* tag 'sti-soc-for-v4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/pchotard/sti:

This patch implements the write_sec callback that handle PL310
secure registers writes.
This callback is just a stub for now, to avoid system crash.
Later, it could handle SMC calls so that TZ handles the needed writes.Signed-off-by: Patrice Chotard

This string is used by dump_stack and as we now support
more SoC's than just STiH415/6 it is misleading to have
the current string in the stack trace.This patch updates it to be more generic for the STi
family of SoCs.So instead of looking like this
[ 271.672555] Hardware name: STiH415/416 SoC with Flattened Device Tree
[ 271.678998] [] (unwind_backtrace) from [] (show_stack+0x10/0x14)
[ 271.686746] [] (show_stack) from [] (dump_stack+0x98/0xac)

This replaces:
- "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can
now be selected directly.- "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB
is now selectable by everyone, so we need not declare our
intent to select it.When ordering the symbols the following rationale was used:
if the selects were in alphabetical order, I moved select GPIOLIB
to be in alphabetical order, but if the selects were not
maintained in alphabetical order, I just replaced
"select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".Cc: Michael Büsch

Many ARM sub-architectures use prompts followed by "if" conditional,
but it is wrong.Please notice the difference between
config ARCH_FOO
bool "Foo SoCs" if ARCH_MULTI_V7and
config ARCH_FOO
bool "Foo SoCs"
depends on ARCH_MULTI_V7These two are *not* equivalent!
In the former statement, it is not ARCH_FOO, but its prompt that
depends on ARCH_MULTI_V7. So, it is completely valid that ARCH_FOO
is selected by another, but ARCH_MULTI_V7 is still disabled. As it is
not unmet dependency, Kconfig never warns. This is probably not what
you want.The former should be used only when you need to do so, and you really
understand what you are doing. (In most cases, it should be wrong!)For enabling/disabling sub-architectures, the latter is always correct.
As a good side effect, this commit fixes some entries over 80 columns
(mach-imx, mach-integrator, mach-mbevu).[Arnd: I note that there is not really a bug here, according to
the discussion that followed, but I can see value in being consistent

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

A number of configurations spit out warnings similar to:

warning: (SOC_IMX6 && SOC_VF610 && ARCH_OMAP4) selects PL310_ERRATA_727915 which has unmet direct dependencies (CACHE_L2X0)Clean up the dependencies here:
* PL310 symbols should only be selected when CACHE_L2X0 is enabled.
* Since the cache-l2x0 code detects PL310 presence at runtime, and we will
eventually get rid of CACHE_PL310, surround these errata options with an
if CACHE_L2X0 conditional rather than repeating the dependency against

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

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.
