This patch refines data structures, which are used to control engine's
data path, to make it more efficient. Hence current change are:

- gathers the broken pieces of structures 'mtk_aes_ct''mtk_aes_tfm'
into struct mtk_aes_info hence avoiding additional DMA-mapping.

- adds 'keymode' in struct mtk_aes_base_ctx. When .setkey() callback is
called, we store keybit setting in keymode. Doing so, there is no need
to check keylen second time in mtk_aes_info_init() / mtk_aes_gcm_info_init().

Besides, this patch also removes unused macro definitions and adds helper
inline function to write security information(key, IV,...) to info->state.

This patch replaces cmd_pos/res_pos with pointer cmd_next/res_next.

In old code, we must to add one to shift ring to the next segment, and
then use this value to caculate current offset from ring base for each

This is a transitional patch. It merges mtk_sha_xmit() and mtk_sha_xmit2()
to make transmit function more generic.
In addition, res->buf and cryp->tmp_dma in mtk_sha_xmit() are useless, since
crypto engine writes the result digests into ctx->tfm.digest instead of
res->buf. It's better to remove it.

Currently, the code that takes a reference to the clock and enables it
is located inside of_get_omap_rng_device_details(), called only when
probing through the Device Tree.

However, there is nothing that makes this clock logic dependent on the
Device Tree, so it makes more sense to have it in omap_rng_probe()
directly.

Moreover, we make sure to bail out if we can't enable the clock. Indeed,
while the clock is optional, if a clock is present, we really want to
succeed in enabling it. And we fix the error message to fit on one line,
so that it is grep-friendly.

When requesting a fallback algorithm, we should propagate the
NEED_FALLBACK bit when search for the underlying algorithm.

This will prevents drivers from allocating unnecessary fallbacks that
are never called. For instance, currently the vmx-crypto driver will use
the following chain of calls when calling the fallback implementation:

p8_aes_ctr -> ctr(p8_aes) -> aes-generic

However p8_aes will always delegate its calls to aes-generic. With this

To prevent unnecessary branching, mark the exit condition of the
primary loop as likely(), given that a carry in a 32-bit counter
occurs very rarely.

On arm64, the resulting code is emitted by GCC as

     9a8:   cmp     w1, #0x3
     9ac:   add     x3, x0, w1, uxtw
     9b0:   b.ls    9e0 <crypto_inc+0x38>

     9c8:   cbz     w2, 9d0 <crypto_inc+0x28>
     9cc:   ret

where the two remaining branch conditions (one for size < 4 and one for
the carry) are statically predicted as non-taken, resulting in optimal
execution in the vast majority of cases.

Also, replace the open coded alignment test with IS_ALIGNED().

Currently, the bit sliced NEON AES code for ARM has a link time
dependency on the scalar ARM asm implementation, which it uses as a
fallback to perform CBC encryption and the encryption of the initial
XTS tweak.

The bit sliced NEON code is both fast and time invariant, which makes
it a reasonable default on hardware that supports it. However, the
ARM asm code it pulls in is not time invariant, and due to the way it
is linked in, cannot be overridden by the new generic time invariant
driver. In fact, it will not be used at all, given that the ARM asm
code registers itself as a cipher with a priority that exceeds the
priority of the fixed time cipher.

So remove the link time dependency, and allocate the fallback cipher
via the crypto API. Note that this requires this driver's module_init
call to be replaced with late_initcall, so that the (possibly generic)
fallback cipher is guaranteed to be available when the builtin test
is performed at registration time.

Interrupt handling routine was calling req->base.complete() under
spinlock.  In most cases this wasn't fatal but when combined with some
of the cipher modes (like LRW) this caused recursion - starting the new
encryption (s5p_aes_crypt()) while still holding the spinlock from
previous round (s5p_aes_complete()).

Beside that, the s5p_aes_interrupt() error handling path could execute
two completions in case of error for RX and TX blocks.

Rewrite the interrupt handling routine and the completion by:

1. Splitting the operations on scatterlist copies from
   s5p_aes_complete() into separate s5p_sg_done(). This still should be
   done under lock.
   The s5p_aes_complete() now only calls req->base.complete() and it has
   to be called outside of lock.

2. Moving the s5p_aes_complete() out of spinlock critical sections.
   In interrupt service routine s5p_aes_interrupts(), it appeared in few
   places, including error paths inside other functions called from ISR.
   This code was not so obvious to read so simplify it by putting the
   s5p_aes_complete() only within ISR level.

The INTMASK_REG register does not exist on EIP76. Due to this, the call:

   omap_rng_write(priv, RNG_INTMASK_REG, RNG_SHUTDOWN_OFLO_MASK);

ends up, through the reg_map_eip76[] array, in accessing the register at
offset 0, which is the RNG_OUTPUT_0_REG. This by itself doesn't cause
any problem, but clearly doesn't enable the interrupt as it was
expected.

On EIP76, the register that allows to enable the interrupt is
RNG_CONTROL_REG. And just like RNG_INTMASK_REG, it's bit 1 of this
register that allows to enable the shutdown_oflo interrupt.

Commit 38321242 ("hwrng: omap - Add device variant for SafeXcel
IP-76 found in Armada 8K") added support for the SafeXcel IP-76 variant
of the IP. This modification included getting a reference and enabling a
clock. Unfortunately, this was done *after* writing to the
RNG_INTMASK_REG register. This generally works fine when the driver is
built-in because the clock might have been left enabled by the
bootloader, but fails short when the driver is built as a module: it
causes a system hang because a register is being accessed while the
clock is not enabled.

This commit fixes that by making the register access *after* enabling
the clock.

This issue was found by the kernelci.org testing effort.

Turning on crypto self-tests on a POWER8 shows:

Comparing the code with the Intel CRC32c implementation on which
ours is based shows that we are doing an init with 0, not ~0
as CRC32c requires.

This probably wasn't caught because btrfs does its own weird
open-coded initialisation.

Initialise our internal context to ~0 on init.

This makes the self-tests pass, and btrfs continues to work.
