that enable a new option that automatically loads keys from db
and MOK into the secondary keyring, so that they can be used to
verify the signature of kernel modules. Enable the required KCONFIGs.
Allows users to self-sign modules (eg: dkms).
With this option enabled, the kernel will be able to retrieve firmware
logs by looking in the coreboot table. This can be accessed from
userspace via the sysfs file /sys/firmware/log.

We were building the omap-rng driver, because the same block is used
on some recent Marvell chips and HW_RANDOM_OMAP is enabled by default
if ARCH_MVEBU is enabled.
We were also building virtio-rng, but there isn't (so far as I know)
any publicly available emulation of the ARMv5 Marvell chips.
As we're about to include HWRNG drivers to the installer, disable the
whole subsystem for armel/marvell to avoid adding useless drivers.
It appears to be technically possible to use PCMCIA cards on POWER8/9
systems through a PCI Express to PCI adapter and a PCI to
PCMCIA/CardBus adapter. But I can't believe anyone would want to.
So rather than adding a pcmcia-modules package or excluding the
drivers from udebs, disable PCMCIA altogether.
Module loading needs the issuer certificate to validate the signature,
and that certificate is not embedded in the signature itself.
For now embed both the signing certificate and the root CA.
With this option set, module text and rodata memory areas will be made
read-only. Moreover, non-text memory will be made non-executable. This
provides protection against certain security exploits. Currently, this
option is implicitly enabled in Kconfig for most configurations where it
is possible to enable it. This commit enables the option by default
explictly for all supported targets (except marvell to keep it small)
When set, this generates crash dump after being started by kexec. Useful
for debugging purpose on ARM. As this is already enabled for other arch,
enable it for ARM, as well (except marvell to keep it small).
Nowadays, Raspberry Pi 2 and Rasberry Pi 3 works perfectly fine with
Debian (including the official kernel package or the userland). RPi 1
and RPi Zero have an SoC that contains an armv6-based CPU, this means
that it cannot work with an hardfloat ABI, that is armv7 based. So we
have to use the Debian armel userland for this reason. Both boards are
supported in the mainline linux kernel and not being supported in the
debian-kernel package is the only blocking point that prevent RPI 1 and
RPI Zero from being well supported in an official Debian distribution.
This commit add a new kernel flavour for enabling support for the both
platforms.
Enabling this symbol makes rmi4_core depend on the media/v4l2
subsystem which is not only weird but also results in duplicate
modules at kernel-wedge time.
