This patch had support for the TRNG present in the CE.
Note that according to the algorithm ID, 2 version of the TRNG exists,
the first present in H3/H5/R40/A64 and the second present in H6.
This patch adds support for both, but only the second is working
reliabily according to rngtest.

The code in the current implementation of safexcel_hmac_alg_setkey
can be reused by safexcel_cipher. This patch does just that by
renaming the previous safexcel_hmac_setkey to __safexcel_hmac_setkey.
The now-shared safexcel_hmac_alg_setkey becomes safexcel_hmac_setkey
and a new safexcel_hmac_alg_setkey has been added for use by ahash
transforms.
As a result safexcel_aead_setkey's stack frame has been reduced by
about half in size, or about 512 bytes.

MDIO reads can happen during PHY probing, and printing an error with
dev_err can result in a large number of error messages during device
probe. On a platform with a serial console this can result in
excessively long boot times in a way that looks like an infinite loop
when multiple busses are present. Since 0f183fd151c (net/fsl: enable
extended scanning in xgmac_mdio) we perform more scanning so there are
potentially more failures.
Reduce the logging level to dev_dbg which is consistent with the
Freescale enetc driver.

Move the lapb_register/lapb_unregister calls into the ndo_open/ndo_stop
functions.
This makes the LAPB protocol start/stop when the network interface
starts/stops. When the network interface is down, the LAPB protocol
shouldn't be running and the LAPB module shoudn't be generating control
frames.
2.
Move netif_start_queue/netif_stop_queue into the ndo_open/ndo_stop
functions.
This makes the TX queue start/stop when the network interface
starts/stops.
(netif_stop_queue was originally in the ndo_stop function. But to make
the code look better, I created a new function to use as ndo_stop, and
made it call the original ndo_stop function. I moved netif_stop_queue
from the original ndo_stop function to the new ndo_stop function.)

For far layout, the discard region is not continuous on disks. So it needs
far copies r10bio to cover all regions. It needs a way to know all r10bios
have finish or not. Similar with raid10_sync_request, only the first r10bio
master_bio records the discard bio. Other r10bios master_bio record the
first r10bio. The first r10bio can finish after other r10bios finish and
then return the discard bio.

Now the discard request is split by chunk size. So it takes a long time
to finish mkfs on disks which support discard function. This patch improve
handling raid10 discard request. It uses the similar way with patch
29efc390b (md/md0: optimize raid0 discard handling).
But it's a little complex than raid0. Because raid10 has different layout.
If raid10 is offset layout and the discard request is smaller than stripe
size. There are some holes when we submit discard bio to underlayer disks.
For example: five disks (disk1 - disk5)
D01 D02 D03 D04 D05
D05 D01 D02 D03 D04
D06 D07 D08 D09 D10
D10 D06 D07 D08 D09
The discard bio just wants to discard from D03 to D10. For disk3, there is
a hole between D03 and D08. For disk4, there is a hole between D04 and D09.
D03 is a chunk, raid10_write_request can handle one chunk perfectly. So
the part that is not aligned with stripe size is still handled by
raid10_write_request.
If reshape is running when discard bio comes and the discard bio spans the
reshape position, raid10_write_request is responsible to handle this
discard bio.
I did a test with this patch set.

In current implementation, grow_buffers() uses alloc_page() to
allocate the buffers for each stripe_head, i.e. allocate a page
for each dev[i] in stripe_head.
After setting stripe_size as a configurable value by writing
sysfs entry, it means that we always allocate 64K buffers, but
just use 4K of them when stripe_size is 4K in 64KB arm64.
To avoid wasting memory, we try to let multiple sh->dev share
one real page. That means, multiple sh->dev[i].page will point
to the only page with different offset. Example of 64K PAGE_SIZE
and 4K stripe_size as following:
64K PAGE_SIZE
+---+---+---+---+------------------------------+
| | | | |
| | | | |
+-+-+-+-+-+-+-+-+------------------------------+
^ ^ ^ ^
| | | +----------------------------+
| | | |
| | +-------------------+ |
| | | |
| +----------+ | |

+-+ | | |
| | | |
+-----+-----+------+-----+------+-----+------+------+
sh | offset(0) | offset(4K) | offset(8K) | offset(12K) |
+ +-----------+------------+------------+-------------+
+----> dev[0].page dev[1].page dev[2].page dev[3].page
A new 'pages' array will be added into stripe_head to record shared
page used by this stripe_head. Allocate them when grow_buffers()
and free them when shrink_buffers().
After trying to share page, the users of sh->dev[i].page need to take
care of the related page offset: page of issued bio and page passed
to xor compution functions. But thanks for previous different page offset
supported. Here, we just need to set correct dev[i].offset.

For now, syndrome compute functions require common offset in the pages

Since the only caller of async_gen_syndrome() and async_syndrome_val()

interface directly. After that, replacing old interfaces with new ones
