Now that we have separate files for each kernel version,
only the version/hash for the target kernel are available.
This cause a missing hash error (and wrong kernel version) for
bpf-headers when a testing kernel version is used for the current target.

Fix this error by manually including the kernel version/hash file for the
specific kernel version requested.

this should have been removed together with linux 5.4 APM821XX

will in the next stable kernel release.

GENERIC_PLATFORM_DIR to make it work. This points it at the files from

The lantiq AES hardware does not support the gcm algorithm. But it
can be implemented in the driver as a combination of the aes_ctr
algorithm and the xor plus gfmul operations for the hashing.
Due to the wrapping of the several algorithms and the inefficient
16 byte block by 16 byte block invokation in the kernel
implementations, this driver is about 3 times faster for the larger
block sizes.

After adding xts and cbcmac the aes algorithm source had three sections
for setting the aes key to the hardware which are identical.
Method aes_set_key_hw was created which is now called from within the
spinlock secured control sections in methods ifx_deu_aes, ifx_deu_aes_xts
and aes_cbcmac_final_impl and reduces the size of ifxmips_aes.c.

Since commit 53b67839 hostapd is using the kernel api which includes the
cbcmac-aes shash algorithm. The kernels implementation is a wrapper around
the aes encryption algorithm, which encrypts block (16 bytes) by block.
When the ltq-deu driver is present, it uses hardware aes, but every 16 byte
encrypt requires setting the key. This is very inefficient and is a huge
overhead. Since the cbcmac-aes is simply a hash that uses the cbc aes
algorithm starting with an iv set to x'00' with an optional ecb aes
encryption of a possible last incomplete block that is padded with the
positional bytes of the last cbc encrypted block, this algorithm is now
added to the driver. Most of the code is derived from md5-hmac and
tailored for aes. Tested with the kernels crypto testmgr including extra
tests against the kernels generic ccm module implementation.
This patch also fixes the overallocation in the aes_ctx that is caused
by using u32 instead of u8 for the aes keys.

just an XOR with the IV, followed by AES ECB, followed by another
XOR with the IV and as such can be also implemented by using the
lantiq hardware's CBC AES implemention plus one additional XOR with
the IV in the driver. The output IV by CBC AES is also not usable
and the gfmul operation not supported by lantiq hardware. Both need
to be done in the driver too in addition to the IV treatment which is
the initial encryption by the other half of the input key and to
set the IV to the IV registers for every block.
In the generic kernel implementation, the block size for XTS is set
to 16 bytes, although the algorithm is designed to process any size
of input larger than 16 bytes. But since there is no way to
indicate a minimum input length, the block size is used. This leads
to certain issues when the skcipher walk functions are used, e.g.
processing less than block size bytes is not supported by calling
skcipher_walk_done.
The walksize is 2 AES blocks because otherwise for splitted input
or output data, less than blocksize is to be returned in some cases,
which cannot be processed. Another issue was that depending on
possible split of input/output data, just 16 bytes are returned while
less than 16 bytes were remaining, while cipher text stealing
requires 17 bytes or more for processing.
For example, if the input is 60 bytes and the walk is 48, then
processing 48 bytes leads to a return code of -EINVAL for
skcipher_walk_done. Therefor the processed counter is used to
figure out, when the actual cipher text stealing for the remaining
bytes less than blocksize needs to be applied.
Measured with cryptsetup benchmark, this XTS AES implementation is
about 19% faster than the kernels XTS implementation that uses the
hardware ECB AES (ca. 18.6 MiB/s vs. 15.8 MiB/s decryption 256b key).
The implementation was tested with the kernels crypto testmgr against
the kernels generic XTS AES implementation including extended tests.

The processing in the hmac algorithms depends on the status fields:
count, dbn and started. Not all were initialised in the init method
and after finishing the final method. Added missing fields to init
method and call init method after finishing final.
The memsets have the wrong size in the original driver and did not
clear everything and are not necessary. Since no memset is done in
the kernels generic implementation, memsets were removed.

Removing hash pointer in _hmac_setkey since its not needed and causes
a compiler warning.
Make the spinlock control sections shorter and move initializations
out of the control sections to free the spinlock faster for allowing
other threads to use the hash engine.
Minor improvements for indentation and removal of blanks and blank
lines in some areas.

Exceeding the temp array size was not checked and instead storage not
allocated by the driver was used/overwritten which in most cases
resulted in reboots. This patch implements processing the input to the
hash algorithm in tempsize chunks.
The _hmac_final methods were changed to _hmac_final_impl adding a
parameter that indicates intermediate or final processing. The started
variable was added to the context to indicate, if there is an
intermediate result in the context. For sha1_hmac the variable to store
the intermediate hash was added to the context too.
In order to avoid md5_hmac_final_impl being recursively called if the
padding of the input and the resulting last transform during the hmac
algorighms final processing causes the temp array to overflow and to
make sure that there is at least one block in the temp array when the
_hmac_final for final processing is called, the check for exceeding
the temp array in _hmac_transform was moved before copying the block
and incrementing dbn. dbn needs to be at least 1 at final processing
time to let the hash engine apply the opad operation.
To make the hash engine not apply the hmac algorithms final opad
operation, for intermediate processing the dbn in the control register
is set to a higher value than number of dbns are actually processed.

The hmac algorithms state, that keys larger than the key size should be
hashed with the underlying hash algorithms and then those hashes are to
be used as keys. This patch implements this. In order to avoid allocating
a descriptor during setkey, a shash_desc pointer is added to the context.
Another issue for multithreaded callers is the shared temp array.
The temp array is static and as such would be shared among multithreaded
callers, which obviously would neither work nor produce correct results.
The temp array (4k size) is moved to the context and since the size of
the context is limited, it can only be defined as pointer otherwise the
initialisation of the hash algorithm fails.
The allocations and freeing of both the temp and the desc pointer in the
context are done by implementing cra_init and cra_exit functions for
the hmac algorithms.
Also improved indentation in some areas.

The algorithms sha1, sha1_hmac and md5_hmac all use ENDI=1. The md5
algorithm uses ENDI=0 and the endian_swap methods to reverse the
endianess switch by using user CPU time, which is unnecessary overhead.
Danube and AR9 devices do not set endianess for SHA1, so is done for
MD5.
Furthermore the patch replaces endian_swap with le32_to_cpu for md5 and
md5 hmac algorithms and removes endian_swap for them.
The init functions initialize the algorithm in the hardware. The lock is
not used to write to the control register. If another thread calls
another hash algo before update or final, the result will be wrong.
Therefore move the algorithm init to the lock protected sections in the
transform or final methods.
Setting the hw key for the hmac algorithms is now done from within the
lock protected sections in their final methods. The lock protecting is
removed from the _hmac_setkey_hw functions.
In final for md5 and sha1 the lock section is removed, because all the
work was already done in transform (which is called from final). As such
only copying the hash to the output is required.
MD5 and MD5_HMAC produce 16 byte hashes (4 DWORDS) only, therefor
writing register D5R to the hash output is removed for MD5_HMAC.

All hash algorithms use the same base IFX_HASH_CON to access the hash unit.
Parallel threads should not be able to call different hash algorithms and
therefor a global lock is required.
Fixed linker warning, that md5_hmac_init, md5_hmac_update and
md5_hmac_final are static export symbols. The export symbols are not
required, because the functions are exposed using shash_alg structure.
