Both qi.h and cammalg_qi2.h seem to define identical versions of
MAX_SDLEN. Move it to desc_constr.h to avoid duplication.

Since 32-bit of both wr_reg64 and rd_reg64 now use 64-bit IO helpers,
these functions should no longer be necessary. No functional change intended.

In order to be able to unify 64 and 32 bit implementations of
wr_reg64, let's convert it to use helpers from
<linux/io-64-nonatomic-hi-lo.h> first. Here are the steps of the
transformation:
1. Inline wr_reg32 helpers:
if (!caam_imx && caam_little_end) {
if (caam_little_end) {
iowrite32(data >> 32, (u32 __iomem *)(reg) + 1);
iowrite32(data, (u32 __iomem *)(reg));
} else {
iowrite32be(data >> 32, (u32 __iomem *)(reg) + 1);
iowrite32be(data, (u32 __iomem *)(reg));
}
} else {
if (caam_little_end) {
iowrite32(data >> 32, (u32 __iomem *)(reg));
iowrite32(data, (u32 __iomem *)(reg) + 1);
} else {
iowrite32be(data >> 32, (u32 __iomem *)(reg));
iowrite32be(data, (u32 __iomem *)(reg) + 1);
}
}
2. Transfrom the conditionals such that the check for
'caam_little_end' is at the top level:
if (caam_little_end) {
if (!caam_imx) {
iowrite32(data >> 32, (u32 __iomem *)(reg) + 1);
iowrite32(data, (u32 __iomem *)(reg));
} else {
iowrite32(data >> 32, (u32 __iomem *)(reg));
iowrite32(data, (u32 __iomem *)(reg) + 1);
}
} else {
iowrite32be(data >> 32, (u32 __iomem *)(reg));
iowrite32be(data, (u32 __iomem *)(reg) + 1);
}
3. Invert the check for !caam_imx:
if (caam_little_end) {
if (caam_imx) {
iowrite32(data >> 32, (u32 __iomem *)(reg));
iowrite32(data, (u32 __iomem *)(reg) + 1);
} else {
iowrite32(data >> 32, (u32 __iomem *)(reg) + 1);
iowrite32(data, (u32 __iomem *)(reg));
}
} else {
iowrite32be(data >> 32, (u32 __iomem *)(reg));
iowrite32be(data, (u32 __iomem *)(reg) + 1);
}
4. Make use of iowrite64* helpers from <linux/io-64-nonatomic-hi-lo.h>
if (caam_little_end) {
if (caam_imx) {
iowrite32(data >> 32, (u32 __iomem *)(reg));
iowrite32(data, (u32 __iomem *)(reg) + 1);
} else {
iowrite64(data, reg);
}
} else {
iowrite64be(data, reg);
}
No functional change intended.

Until now, the inside-secure driver required a set of firmware images
supplied by the silicon vendor, typically under NDA, to be present in
/lib/firmware/inside-secure in order to be able to function.
This patch removes the dependence on this official vendor firmware by
falling back to generic "mini" FW - developed specifically for this
driver - that can be provided under GPL 2.0 through linux-firmwares.

This removes some code determine which engine has which algorithms which
was effectively redundant (may have been forward-looking?) due to always
enabling all algorithms for all currently supported engines.
A future patch will use a different, more scalable approach to achieve
this. This is removed now because otherwise the next patch will add new
hardware which would otherwise have to be added to all algorithms, so
now is a convenient time to just get rid of this.

While being a generic EIP97/EIP197 driver, the driver was only selectable
for Marvell Armada hardware. This fix makes the driver selectable for any
Device Tree supporting kernel configuration, allowing it to be used for
other compatible hardware by just adding the correct device tree entry.
It also allows the driver to be selected for PCI(E) supporting kernel con-
figurations, to be able to use it with PCIE based FPGA development boards
for pre-silicon driver development by both Inside Secure and its IP custo-
mers.

The s5p skcipher driver returns -EINVAL for zero length inputs, which
deviates from the behavior of the generic ECB template, and causes fuzz
tests to fail. In cases where the input is not a multiple of the AES
block size (and the chaining mode is not CTR), it prints an error to
the kernel log, which is a thing we usually try to avoid in response
to situations that can be triggered by unprivileged users.

For correctness and compliance with the XTS-AES specification, we are
adding support for ciphertext stealing to XTS implementations, even
though no use cases are known that will be enabled by this.
Since the Power8 implementation already has a fallback skcipher standby
for other purposes, let's use it for this purpose as well. If ciphertext
stealing use cases ever become a bottleneck, we can always revisit this.

Another one for the cipher museum: split off DES core processing into
a separate module so other drivers (mostly for crypto accelerators)
can reuse the code without pulling in the generic DES cipher itself.
This will also permit the cipher interface to be made private to the
crypto API itself once we move the only user in the kernel (CIFS) to
this library interface.

The kthread calling this function is freezable after commit 03a3bb7ae631
("hwrng: core - Freeze khwrng thread during suspend") is applied.
Unfortunately, this function uses wait_event_interruptible() but doesn't
check for the kthread being woken up by the fake freezer signal. When a
user suspends the system, this kthread will wake up and if it fails the
entropy size check it will immediately go back to sleep and not go into
the freezer. Eventually, suspend will fail because the task never froze
and a warning message like this may appear:
PM: suspend entry (deep)
Filesystems sync: 0.000 seconds
Freezing user space processes ... (elapsed 0.001 seconds) done.
OOM killer disabled.
Freezing remaining freezable tasks ...
Freezing of tasks failed after 20.003 seconds (1 tasks refusing to freeze, wq_busy=0):

Check for a freezer signal here and skip adding any randomness if the
task wakes up because it was frozen. This should make the kthread freeze
properly and suspend work again.

The hwrng_fill() function can run while devices are suspending and
resuming. If the hwrng is behind a bus such as i2c or SPI and that bus
is suspended, the hwrng may hang the bus while attempting to add some
randomness. It's been observed on ChromeOS devices with suspend-to-idle
(s2idle) and an i2c based hwrng that this kthread may run and ask the
hwrng device for randomness before the i2c bus has been resumed.
Let's make this kthread freezable so that we don't try to touch the
hwrng during suspend/resume. This ensures that we can't cause the hwrng
backing driver to get into a bad state because the device is guaranteed
to be resumed before the hwrng kthread is thawed.
