718cf2ccb9 sys/dev: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

fcb93d7493 Enable proper configuration of CESA MBUS windows
For all Marvell devices, MBUS windows configuration is done
in a common place. Only CESA was an exception, so move its
related code from driver to mv_common.c. This way it uses
same proper DRAM information, same as  all other interfaces
instead of parsing DT /memory node directly.

c0f1c1f8ff Fix SHA256 usage on older CESA versions
Adding SHA256 support to Marvell crypto driver resulted in regression
for older SoC's, not capable of handling this mode in hardware.

81526b839f Use SoC ID - based detection in CESA
This commit introduces following changes in order to get rid of
ifdef's from all around the driver.
* Introduce sc_soc_id field in cesa_softc structure - this value is
  obtained in cesa_attach() anyway, so make use of it.
* Replace ifdefs with SoC ID checks.
* Perform PM control status only for relevant SoC's.

2cf4c169db Use proper interface for FDT parsing and memory mapping in CESA
Improvements after r301220.
Bus space methods are not called so simple pmap_mapdev will suffice.
Use OF_getencprop to get buffer with already converted endianess.

b07df6e5a9 Add HMAC-SHA256 support in CESA
Only HMAC-SHA256 is added as it is the only SHA-2 variant supported by
cryptodev. It is not possible to register hardware support for other
algorithms in the family including regular non-keyed SHA256.

1e964f8a52 Truncate HMAC output only if requested by the client
The output of HMAC was previously truncated to 12 bytes. This was only
correct in case of one particular crypto client - the new version of IPSEC.
Fix by taking into account the cri_mlen field in cryptoini session request
filled in by the client.

22c7a03178 Split CESA memory resource into TDMA and CESA regs
TDMA and CESA registers are placed in different ranges of memory. Split
memory resource in DTS to reflect that. This change is needed to support
multiple CESA nodes as otherwise the ranges of different nodes would
overlap.

In consequence, CESA_WRITE and CESA_READ macros have been split depending
on which range of registers is accessed. Offsets for CESA registers have
been modified as the base address has changed.

5188e3cca6 Map CESA SRAM memory in driver attach for Armada38x
On other platforms with CESA accelerator the SRAM memory is mapped in
early init before driver is attached. This method only works correctly
with mappings no smaller than L1 section size (1MB). There may be more
SRAM blocks and they may have smaller sizes than 1MB as is the case
for Armada38x. Instead, map SRAM memory with bus_space_map() in CESA
driver attach. Note that we can no longer assume that VA == PA for the
SRAM.

add35ed5b8 Follow r261352 by updating all drivers which are children of simplebus
to check the status property in their probe routines.

Simplebus used to only instantiate its children whose status="okay"
but that was improper behavior, fixed in r261352.  Now that it doesn't
check anymore and probes all its children; the children all have to
do the check because really only the children know how to properly
interpret their status property strings.

Right now all existing drivers only understand "okay" versus something-
that's-not-okay, so they all use the new ofw_bus_status_okay() helper.

6ac6f295b0 Final pass at having devices use their bus parent for dma tags. The
remaining drivers that haven't been converted have various problems or
complexities that will be dealt with later.  This list includes:

hptrr, hptmv, hpt27xx - device aggregation across multiple parents
drm - want to talk to the maintainer first
tsec, sec - Openfirmware devices, not sure if changes are warranted
fatm - Done except for unused testing code
usb - want to talk to the maintainer first
ce, cp, ctau, cx - Significant driver changes needed to convey parent info

There are also devices tucked into architecture subtrees that I'll leave
for the respective maintainers to deal with.

4b7ec27007 - There's no need to overwrite the default device method with the default
one. Interestingly, these are actually the default for quite some time
  (bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9)
  since r52045) but even recently added device drivers do this unnecessarily.
  Discussed with: jhb, marcel
- While at it, use DEVMETHOD_END.
  Discussed with: jhb
- Also while at it, use __FBSDID.
