ARM: Clean up CONFIG_ARMV7_NONSEC/VIRT/PSCI conditions

2015-05-13T16:24:13+00:00

CONFIG_ARMV7_VIRT depends on CONFIG_ARMV7_NONSEC, thus doesn't need to
be taken into account additionally. CONFIG_ARMV7_PSCI is only set on
boards that support CONFIG_ARMV7_NONSEC, and it only works on those.

common: Make sure arch-specific map_sysmem() is defined

2015-04-18T17:11:09+00:00

In the case where the arch defines a custom map_sysmem(), make sure that
including just mapmem.h is sufficient to have these functions as they
are when the arch does not override it.

Also split the non-arch specific functions out of common.h

armv8/fsl-lsch3: Convert flushing L3 to assembly to avoid using stack

2015-02-24T21:08:46+00:00

Flushing L3 cache in CCN-504 requries d-cache to be disabled. Using
assembly function to guarantee stack is not used before flushing is
completed. Timeout is needed for simualtor on which CCN-504 is not
implemented. Return value can be checked for timeout situation.

Change bootm.c to disable dcache instead of simply flushing, required
by flushing L3.

ARM: bootm: do not add PSCI to fdt when booting in secure mode.

2015-01-05T20:02:03+00:00

Commit 8bc347e2ec17 "ARM: bootm: Allow booting in secure mode on hyp capable
systems" added the capability to select nonsec vs sec mode boot via an
environment var.

There is a subtle gotcha with this functionality, which is that the PSCI nodes
are still created in the fdt (via armv7_update_dt->fdt_psci) even when booting
in secure mode. Which means that if the kernel is PSCI aware then it will fail
to boot because it will try and do PSCI from secure world, which won't work.

This likely didn't get noticed before because the original purpose was to
support booting the legacy linux-sunxi kernels which don't understand PSCI.

To fix expose boot_nonsec (renaming with armv7_ prefix) outside of bootm.c and
use from the virt-dt code.

As well as avoiding the creation of the PSCI nodes we should also avoid
reserving the secure RAM, so do so.

ARM: bootm: Allow booting in secure mode on hyp capable systems

2014-11-24T08:09:52+00:00

Older Linux kernels will not properly boot in hyp mode, add support for a
bootm_boot_mode environment variable, which can be set to "sec" or "nonsec"
to force booting in secure or non-secure mode when build with non-sec support.

The default behavior can be selected through CONFIG_ARMV7_BOOT_SEC_DEFAULT,
when this is set booting in secure mode is the default. The default setting
for this Kconfig option is N, preserving the current behavior of booting in
non-secure mode by default when non-secure mode is supported.

ARM: prevent compiler warnings from bootm.c

2014-10-21T08:47:13+00:00

Without preceding declarations, "make C=1" generates
"Should it be static?" warnings for symbols
	do_bootm_linux,
	boot_prep_vxworks, and
	boot_jump_vxworks

Include of bootm.h also identified a signature mismatch
(const on argv[]).
