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.

ae0f418aa4 Remove remaining ifdefs from CESA header
Commit r312743 ("Use SoC ID - based detection in CESA") resulted
in build failing for Marvell armv5 platforms, which don't support
the newer version of CESA controller. This patch provides a fix by
removing ifdefs around bitfields' definitions, so that they are
known to all platforms.

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.

99eef68204 Move initialization of CESA decoding windows from common section
to driver specific files.

- window initialization is done during device attach
- CESA TDMA decoding windows values are set based on DTS,
 not copied from CPU registers
- remove unnecessary virtual mapping
- update dts file
