the Intel i6300esb is QEMU's default watchdog. And unlike
the real "Intel i6300ESB I/O Controller hub" hardware, the

ARM (armvirt 32bit) and potentially virtual PowerPC and MIPS
targets (if there was any).

The driver maintains elapsed times by repeatedly accumulating the time
since the previous update in a loop. For the elapsed showtime time, the
time difference is truncated to seconds before adding it, leading to a
sizable error over time.
Move the truncation to before calculation of the time difference in
order to remove this error. Also maintain the total elapsed time in the
same way in full seconds, to prevent the unsigned 32-bit counter from
wrapping around after about 50 days.
Testing on a VR9 device shows that the reported line uptime now matches
the actual elapsed wall time. The ADSL variant is only compile-tested,
but it should also work as the relevant code is identical.

Right now, both ltq-adsl-mei and ltq-vdsl-mei are always built, even
when they aren't necessary for the selected variant. This can cause the
build to fail, for example ltq-vdsl-mei doesn't build successfully here
on xway target due to the vectoring callback.
Make these dependencies conditional on the specific package variants,
so they are only built when actually needed.

"The patch looks wrong to me. I'm pretty sure that AR_CH0_TOP2 is the

I believe this patch works by accident because it avoids writing a wrong

ath9k is setting the TX PA DC bias level different on QCA9561 and QCA9565
although they have the same radio IP-core, which results in a very low
output power and very low throughput as devices are further away from
the AP (compared to other 2.4GHz APs.)
In real life testing, without this patch the 2.4GHz throughput on Yuncore
XD3200 is around 10Mbps sitting close to the AP, and close to theoretical

Some users noticed repeated resyncs at random intervals, which go away
when the MEI driver is configured to use polling instead of interrupts.
Debugging shows that this seems to be caused by concurrent calls to
MEI_ReadMailbox (in the interrupt handler) and MEI_WriteMailbox. This
appears to be mostly triggered when there is an interrupt for vectoring
error reports.
In polling mode, calls to MEI_ReadMailbox are protected by the same
semaphore as is used in MEI_WriteMailbox. When interrupts are used,
MEI_WriteMailbox appears to rely on MEI_DisableDeviceInt and
MEI_EnableDeviceInt to provide mutual exclusion with the interrupt
handler. These functions mask/unmask interrupts, and there is an
additional check of the mask in the interrupt handler itself. However,
this is not sufficient on systems with SMP, as the interrupt handler
may be running in parallel, and could already be past the interrupt
mask check at this point.
This adds a lock to the interrupt handler, and also acquires this lock
in MEI_DisableDeviceInt. This should make sure that after a call to
MEI_DisableDeviceInt the interrupt is masked, and the interrupt handler
is either not running, has alread finished its work, or is still before
the interrupt mask check, and is thus going to detect the change.

In order to calculate the required pre-distortion for downstream
vectoring, the vectoring control entity (VCE) at the carrier office
needs error samples from the modem. On Lantiq VR9 modems, error reports
are generated by the firmware, but need to be multiplexed into the data
stream by the driver on the main processor when L2 encapsulation is
selected by the VCE.
This driver provides the necessary callback function, which is called by
the MEI driver after receiving an error report from the firmware.
Originally, it is part of the Lantiq PPA driver, but after a few changes
it also works with the PTM driver used in OpenWrt. The direct call to
ndo_start_xmit needs to be replaced, as the PTM driver relies on locks
from the kernel. Instead dev_queue_xmit is used, which is called from a
work queue, as it is not safe to call from an interrupt handler.
Additional changes include fixes to support recent kernel versions and
a change of the used interface from ptm0 to dsl0.

Package the ability to log kernel crashes to 'ramoops' pstore
files into RAM in /sys/fs/pstore
Reference to the ramoops admin guide in upstream Linux:
https://www.kernel.org/doc/html/v5.10/admin-guide/ramoops.html
The files in RAM survive a warm reboot, but not a cold reboot.
Note: kmod-ramoops selects kmod-pstore and kmod-reed-solomon.
The feature can be used by selecting the kmod-ramoops and
adding a ramoops reserved-memory definition to the device DTS.
Example from R7800:
reserved-memory {
rsvd@5fe00000 {
reg = <0x5fe00000 0x200000>;
reusable;
};
ramoops@42100000 {
compatible = "ramoops";
reg = <0x42100000 0x40000>;
record-size = <0x4000>;
console-size = <0x4000>;
ftrace-size = <0x4000>;
pmsg-size = <0x4000>;
};
};
If no definition has been made in DTS, no crash log is stored
for the device.

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 53b6783 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.

Remove the dependency on kernel 5.4 from the Makefile to allow the
driver to compile with kernel 5.10 or kernel versions higher than
5.4.

The lantiq AES hardware does not support the xts algorithm. Apart
from the cipher text stealing (XTS), the AES XTS implementation is
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.
