c03a509304 crypto: ccp - invoke fallback for XTS ciphertext stealing
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 ccp driver already has a fallback skcipher standby for
dealing with input sizes other than [16, 512, 1024, 2048, 4096],
just drop the check against the block size.

a672705597 crypto: caam - always select job ring via RSR on i.MX8MQ
Per feedback from NXP tech support the way to use register based
service interface on i.MX8MQ is to follow the same set of steps
outlined for the case when virtualization is enabled, regardless if it
is. Current version of SRM for i.MX8MQ speaks of DECO DID_MS and DECO
DID_LS registers, but apparently those are not implemented, so the
case when SCFGR[VIRT_EN]=0 should be handled the same as the case when
SCFGR[VIRT_EN]=1

9f5db8b5ea crytpo: caam - make use of iowrite64*_hi_lo in wr_reg64
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.

f6cc45c854 crypto: inside-secure - add support for using the EIP197 without vendor firmware
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.

625f269a5a crypto: inside-secure - add support for PCI based FPGA development board
This patch adds support for a PCIE development board with FPGA from Xilinx,
to facilitate pre-silicon driver development by both Inside Secure and its
IP customers. Since Inside Secure neither produces nor has access to actual
silicon, this is required functionality to allow us to contribute.

70e39e2259 crypto: inside-secure - Remove redundant algo to engine mapping code
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.

0f6e5c8234 crypto: inside-secure - make driver selectable for non-Marvell hardware
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.

84a0b00aa4 crypto: s5p - deal gracefully with bogus input sizes
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.

04007b0e6c crypto: des - split off DES library from generic DES cipher driver
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.
