The driver is ported from Freescale's Linux git and can be
found in the
vendor/freescale/imx_2.6.35_maintain
branch.
The driver supports both RNG version C that's part of some Freescale
i.MX3 SoCs and version B that is available on i.MX2x chipsets.

This patch introduces a new device driver s390-trng for the
s390 platform which exploits the new PRNO TRNG cpacf
subfunction. The true-random-number-generator is accessible
from userspace, by default visible as /dev/trng. The driver
also registers at the kernel build-in hwrng API to feed the
hwrng with fresh entropy data. This generic device driver
for hardware random data is visible from userspace as
/dev/hwrng.

Replace existing hw_ranndom/exynos-rng driver with a new, reworked one.
This is a driver for pseudo random number generator block which on
Exynos4 chipsets must be seeded with some value. On newer Exynos5420
chipsets it might seed itself from true random number generator block
but this is not implemented yet.
New driver is a complete rework to use the crypto ALGAPI instead of
hw_random API. Rationale for the change:
1. hw_random interface is for true RNG devices.
2. The old driver was seeding itself with jiffies which is not a
reliable source for randomness.
3. Device generates five random 32-bit numbers in each pass but old
driver was returning only one 32-bit number thus its performance was
reduced.
Compatibility with DeviceTree bindings is preserved.
New driver does not use runtime power management but manually enables
and disables the clock when needed. This is preferred approach because
using runtime PM just to toggle clock is huge overhead.
Another difference is reseeding itself with generated random data
periodically and during resuming from system suspend (previously driver
was re-seeding itself again with jiffies).

We can directly depend on SOC_IMX31 since commit c9ee94965dce
("ARM: imx: deconstruct mxc_rnga initialization")
Since that commit, CONFIG_HW_RANDOM_MXC_RNGA could not be switched on
with unknown symbol ARCH_HAS_RNGA and mxc-rnga.o can't be generated with
ARCH=arm make M=drivers/char/hw_random
Previously, HW_RANDOM_MXC_RNGA required ARCH_HAS_RNGA
which was based on IMX_HAVE_PLATFORM_MXC_RNGA && ARCH_MXC.
IMX_HAVE_PLATFORM_MXC_RNGA was based on SOC_IMX31.

In April 2009, commit d405640 ("Driver Core: misc: add node name support
for misc devices.") inadvertently changed the device node name from
/dev/hw_random to /dev/hwrng. Since 6 years has passed since the change
it seems unpractical to change it back, as this node name is probably
considered ABI by now. So instead, we'll just change the Kconfig help
to match the current situation.

The driver for the "Picochip picoXcell true random number generator" was
added in v2.6.39. Its Kconfig symbol has always depended on
PICOXCELL_PC3X3. But that Kconfig symbol has never been part of the

It can be re-added if its dependencies are actually part of the tree.

HW_RANDOM_ATMEL should not only default to ARCH_AT91, it should depend

Likewise, HW_RANDOM_EXYNOS should depend on ARCH_EXYNOS, as it it

Also set the default to HW_RANDOM for the few architecture-specific

This moves the MTU timer driver from arch/arm/plat-nomadik
to drivers/clocksource and moves the header file to the
platform_data directory.
As this moves the last file being compiled to an object out
of arch/arm/plat-nomadik, we have to "turn off the light"
and delete the plat-nomadik directory, because it is not
allowed to have an empty Makefile in a plat-* directory.
This is probably also a desired side effect of depopulating
the arch/arm directory of drivers. Luckily we have just
deleted all the <plat/*> include files prior to this so
by moving the last one we may delete the directory.
After this all the Ux500 and Nomadik device drivers live
outside of the arch/arm hierarchy.

Pull MIPS updates from Ralf Baechle:
"More hardware support across the field including a bunch of device
drivers. The highlight however really are further steps towards
device tree.
This has been sitting in -next for ages. All MIPS _defconfigs have
been tested to boot or where I don't have hardware available, to at
least build fine."

This patch supports Exynos SOC's PRNG driver. Exynos's PRNG has 5 seeds and
5 random number outputs. Module is excuted under runtime power management control,
so it activates only while it's in use. Otherwise it will be suspended generally.
It was tested on PQ board by rngtest program.

Pull crypto updates from Herbert Xu:
- New cipher/hash driver for ARM ux500.
- Code clean-up for aesni-intel.
- Misc fixes.
Fixed up conflicts in arch/arm/mach-ux500/devices-common.h, where quite
frankly some of it made no sense at all (the pull brought in a
declaration for the dbx500_add_platform_device_noirq() function, which
neither exists nor is used anywhere).
Also some trivial add-add context conflicts in the Kconfig file in
drivers/{char/hw_random,crypto}/
* git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
crypto: aesni-intel - move more common code to ablk_init_common
crypto: aesni-intel - use crypto_[un]register_algs
crypto: ux500 - Cleanup hardware identification

mach-ux500: crypto - core support for CRYP/HASH module.
crypto: ux500 - Add driver for HASH hardware

Pull powerpc updates from Benjamin Herrenschmidt:
"Here are the powerpc goodies for 3.5. Main highlights are:
- Support for the NX crypto engine in Power7+
- A bunch of Anton goodness, including some micro optimization of our
syscall entry on Power7
- I converted a pile of our thermal control drivers to the new i2c
APIs (essentially turning the old therm_pm72 into a proper set of
windfarm drivers). That's one more step toward removing the
deprecated i2c APIs, there's still a few drivers to fix, but we are
getting close
- kexec/kdump support for 47x embedded cores
The big missing thing here is no updates from Freescale. Not sure
what's up here, but with Kumar not working for them anymore things are
a bit in a state of flux in that area."
