PowerPC 601 has been retired.
Remove all associated specific code.
CPU_FTRS_PPC601 has CPU_FTR_COHERENT_ICACHE and CPU_FTR_COMMON.
CPU_FTR_COMMON is already present via other CPU_FTRS.
None of the remaining CPU selects CPU_FTR_COHERENT_ICACHE.
So CPU_FTRS_PPC601 can be removed from the possible features,
hence can be removed completely.

Apparently, 15 cycles of the peripheral clock are used by the controller
for sampling and filtering. Because this was not known before, the rate
calculation is slightly off.

SCL rate appears to be different than what is expected. For example,
We get 164kHz on i2c3 of the vim3 when 400kHz is expected. This is
partially due to the peripheral clock being disabled when the clock is
set.
Let's keep the peripheral clock on after probe to fix the problem. This
does not affect the SCL output which is still gated when i2c is idle.

When the slave address is written in do_start(), SLAVE_ADDR is written
completely. This may overwrite some setting related to the clock rate
or signal filtering.
Fix this by writing only the bits related to slave address. To avoid

Simon reported an issue with the current scalar32_min_max_or() implementation.
That is, compared to the other 32 bit subreg tracking functions, the code in
scalar32_min_max_or() stands out that it's using the 64 bit registers instead

The bound tests on the map value force the upper unsigned bound to be 25769803777
in 64 bit (0b11000000000000000000000000000000001) and then lower one to be 1. By
using OR they are truncated and thus result in the range [1,1] for the 32 bit reg
tracker. This is incorrect given the only thing we know is that the value must be
positive and thus 2147483647 (0b1111111111111111111111111111111) at max for the
subregs. Fix it by using the {u,s}32_{min,max}_value vars instead. This also makes
sense, for example, for the case where we update dst_reg->s32_{min,max}_value in
the else branch we need to use the newly computed dst_reg->u32_{min,max}_value as
we know that these are positive. Previously, in the else branch the 64 bit values
of umin_value=1 and umax_value=32212254719 were used and latter got truncated to
be 1 as upper bound there. After the fix the subreg range is now correct:

handling it:

...

Reduce the build time by doing only one kernel-doc call
per functions that belong to the same group. With that, there's now
50 calls to kernel-doc, which makes the build time for those docs
62% faster:

PD 3.0 spec defines a new mechanism for power role swap called
Fast role swap. This change enables TCPM to support FRS when
acting as sink.
Once the explicit contract is negotiated, sink port is
expected to query the source port for sink caps to
determine whether the source is FRS capable.
Bits 23 & 24 of fixed pdo of the sink caps from the source, when
set, indicates the current needed by the source when fast role
swap is in progress(Implicit contract phasae). 0 indicates that
the source does not support Fast Role Swap.
Upon receiving the FRS signal from the source,
TCPC(TCPM_FRS_EVENT) informs TCPM to start the Fast role swap sequence.
1. TCPM sends FRS PD message: FR_SWAP_SEND
2. If response is not received within the expiry of
SenderResponseTimer, Error recovery is triggered.:
FR_SWAP_SEND_TIMEOUT
3. Upon receipt of the accept message, TCPM waits for
PSSourceOffTimer for PS_READY message from the partner:
FR_SWAP_SNK_SRC_NEW_SINK_READY.
TCPC is expected to autonomously turn on vbus once the FRS
signal is received and vbus voltage falls below vsafe5v within
tSrcFrSwap. This is different from traditional power role swap
where the vbus sourcing is turned on by TCPM.
4. By this time, TCPC most likely would have started to
source vbus, TCPM waits for tSrcFrSwap to see if the
lower level TCPC driver signals TCPM_SOURCING_VBUS event:
FR_SWAP_SNK_SRC_SOURCE_VBUS_APPLIED.
5. When TCPC signals sourcing vbus, TCPM sends PS_READY msg and
changes the CC pin from Rd to Rp. This is the end of fast
role swap sequence and TCPM initiates the sequnce to negotiate
explicit contract by transitioning into SRC_STARTUP after
SwapSrcStart.
The code is written based on the sequence described in "Figure 8-107:
Dual-role Port in Sink to Source Fast Role Swap State Diagram" of
USB Power Delivery Specification Revision 3.0, Version 1.2.

The sm2 code was split out of public_key.c in a way that breaks
modular builds. This patch moves the code back into the same file
as the original motivation was to minimise ifdefs and that has
nothing to do with splitting the code out.

Clang warns:
crypto/xor.c:101:4: warning: variable 'count' is uninitialized when used
here [-Wuninitialized]
count++;
^~~~~
crypto/xor.c:86:17: note: initialize the variable 'count' to silence
this warning
int i, j, count;
^
= 0
1 warning generated.
After the refactoring to use ktime that happened in this function, count
is only assigned, never read. Just remove the variable to get rid of the
warning.

The setkey function for GCM/CCM algorithms didn't verify the key
length before copying the key and subtracting the salt length.
This patch delays the copying of the key til after the verification
has been done. It also adds checks on the key length to ensure
that it's at least as long as the salt.

The pm80xx driver currently sets the controller queue depth to
256. Hoewver, the controller supports outstanding I/Os up 1024.
Increase the number of outstanding I/Os from 256 to 1024. CCBs and tags
are allocated according to outstanding I/Os. Also update the can_queue
value (max_out_io - PM8001_RESERVE_SLOT) used by the SCSI midlayer.

Remove DMA memory allocation for Devices and CCB structure. Instead
allocate memory outside of DMA memory. DMA memory is a limited system
resource and it is better to allocate memory outside of DMA memory when
possible.
