Today, md5sum fails with error -ENOKEY because a setkey
function is set for non hmac hashing algs, see strace output below:
mmap(NULL, 378880, PROT_READ, MAP_SHARED, 6, 0) = 0x77f50000
accept(3, 0, NULL) = 7
vmsplice(5, [{"bin/\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 378880}], 1, SPLICE_F_MORE|SPLICE_F_GIFT) = 262144
splice(4, NULL, 7, NULL, 262144, SPLICE_F_MORE) = -1 ENOKEY (Required key not available)
write(2, "Generation of hash for file kcap"..., 50) = 50
munmap(0x77f50000, 378880) = 0
This patch ensures that setkey() function is set only
for hmac hashing.

An updated patch that also handles the additional key length requirements
for the AEAD algorithms.
The max keysize is not 96. For SHA384/512 it's 128, and for the AEAD
algorithms it's longer still. Extend the max keysize for the
AEAD size for AES256 + HMAC(SHA512).

SEC1 doesn't have IPSEC_ESP descriptor type but it is able to perform
IPSEC using HMAC_SNOOP_NO_AFEU, which is also existing on SEC2
In order to be able to define descriptors templates for SEC1 without
breaking SEC2+, we have to give lower priority to HMAC_SNOOP_NO_AFEU
so that SEC2+ selects IPSEC_ESP and not HMAC_SNOOP_NO_AFEU which is
less performant.
This is done by adding a priority field in the template. If the field
is 0, we use the default priority, otherwise we used the one in the
field.

This patchs enhances the IPSEC_ESP related functions for them to
also supports the same operations with descriptor type
HMAC_SNOOP_NO_AFEU.
The differences between the two descriptor types are:
* pointeurs 2 and 3 are swaped (Confidentiality key and
Primary EU Context IN)
* HMAC_SNOOP_NO_AFEU has CICV out in pointer 6
* HMAC_SNOOP_NO_AFEU has no primary EU context out so we get it
from the end of data out

In preparation of IPSEC for SEC1, first step is to make the mapping
helpers more generic so that they can also be used by AEAD functions.
First, the functions are moved before IPSEC functions in talitos.c
talitos_sg_unmap() and unmap_sg_talitos_ptr() are merged as they
are quite similar, the second one handling the SEC1 case an calling
the first one for SEC2
map_sg_in_talitos_ptr() and map_sg_out_talitos_ptr() are merged
into talitos_sg_map() and enhenced to support offseted zones
as used for AEAD. The actual mapping is now performed outside that
helper. The DMA sync is also done outside to not make it several
times.
talitos_edesc_alloc() size calculation are fixed to also take into
account AEAD specific parts also for SEC1

The probe error path for this driver, for all intents and purposes,
is the talitos_remove() function due to the common "goto err_out".
Without this patch applied, talitos_remove() will panic under these
two conditions:
1. If the RNG device hasn't been registered via
talitos_register_rng() prior to entry into talitos_remove(),
then the attempt to unregister the RNG "device" will cause a panic.
2. If the priv->chan array has not been allocated prior to entry
into talitos_remove(), then the per-channel FIFO cleanup will panic
because of the dereference of that NULL "array".
Both of the above scenarios occur if talitos_probe_irq() fails.
This patch resolves issue #1 by introducing a boolean to mask the
hwrng_unregister() call in talitos_unregister_rng() if RNG device
registration was unsuccessful.
It resolves issue #2 by checking that priv->chan is not NULL in the
per-channel FIFO cleanup for loop.

Therefore, for SEC1 we have to do it by SW. For that, we reserve
space at the end of the extended descriptor, in lieu of the space
reserved for the link tables on SEC2, and we perform sg_copy() when
preparing the descriptors

This patch adapts the interrupts handling and reset function for
SEC1. On SEC1, registers are almost similar to SEC2+, but bits
are sometimes located at different places. So we need to define
TALITOS1 and TALITOS2 versions of some fields, and manage according
to whether it is SEC1 or SEC2.
On SEC1, only one interrupt vector is dedicated to the SEC, so only
interrupt_4ch is needed.
On SEC1, interrupts are enabled by clearing related bits in IMR,
while on SEC2, interrupts are enabled by seting the bits in IMR.
SEC1 also performs parity verification in the DES Unit. We have
to disable this feature because the test vectors provided in
the kernel have parity errors.
In reset functions, only SEC2 supports continuation after error.
For SEC1, we have to reset in all cases.
For errors handling, SEC2+ names have been kept, but displayed
text have been amended to reflect exact meaning on SEC1.

A platform_driver does not need to set an owner, it will be populated by the
driver core.

In function talitos_probe(), it will jump to err_out when getting an
error in talitos_probe_irq(). Then the uninitialized list head
priv->alg_list will be used in function talitos_remove(). In this case
we would get a call trace like the following. So move up the
initialization of priv->alg_list.
