armv8: LS2080A: Consolidate LS2080A and LS2085A

2016-04-06T17:26:46+00:00

LS2080A is the primary SoC, and LS2085A is a personality with AIOP
and DPAA DDR. The RDB and QDS boards support both personality. By
detecting the SVR at runtime, a single image per board can support
both SoCs. It gives users flexibility to swtich SoC without the need
to reprogram the board.

crypto/fsl: Make CAAM transactions cacheable

2016-03-29T15:46:22+00:00

This commit solves CAAM coherency issue on ls2080. When caches are
enabled and CAAM's DMA's AXI transcations are not made cacheable,
Core reads/writes data from/to caches and CAAM does from main memory.
This forces data flushes to synchronize various data structures. But
even if any data in proximity of these structures is read by core,
these structures again are fetched in caches.

To avoid this problem, either all the data that CAAM accesses can be
made cache line aligned or CAAM transcations can be made cacheable.

So, this commit makes CAAM transcations as write back with write and
read allocate.

crypto/fsl: Correct 64-bit write when MMU disabled

2016-03-29T15:46:22+00:00

When MMU is disabled, 64-bit write must be aligned at 64-bit
boundary. Becaue the memory location is not guaranteed to be 64-bit
aligned, the 64-bit write needs to be split into two 32-bit writes
to avoid the alignment exception.

drivers/crypto/fsl: define structures for PDB

2016-03-21T19:42:11+00:00

Structures are defined for PDB (Protocol Data Blcks) for various
operations. These structure will be used to add PDB data while
creating the PDB descriptors.

drivers/crypto/fsl: correct error checking in run_descriptor

2016-03-21T19:42:11+00:00

When CAAM runs a descriptor and an error occurs, a non-zero
value is set in Output Status Register. The if condition should
check the status for a non-zero value.

powerpc/SECURE_BOOT: Add PAMU driver

2016-02-24T16:40:55+00:00

PAMU driver basic support for usage in Secure Boot.
In secure boot PAMU is not in bypass mode. Hence to use
any peripheral (SEC Job ring in our case), PAMU has to be
configured.

The patch reverts commit 7cad2e38d61e27ea59fb7944f7e647e97ef292d3.

The Header file pamu.h and few functions in driver have been derived
from Freescale Libos.

drivers/crypto/fsl : Allocate output ring with size aligned to CACHELNE SIZE

2016-02-24T16:40:55+00:00

The output ring needs to be invalidated before enqueuing the job to SEC.
While allocation of space to output ring, it should be taken care that the
size is cacheline size aligned inorder to prevent invalidating valid data.

The patch also correct the method of aligning end of structs while flushing caches

    Since start = align(start_of_struct), it is incorrect to assign
    end = align(start + struct_size). It should instead be,
    end = align(start_of_struct + struct_size).

imx: Refactoring CAAM Job Ring structure and Secure Memory for imx7

2016-02-21T10:20:54+00:00

Refactored data structure for CAAM's job ring and Secure Memory
to support i.MX7.

The new memory map use macros to resolve SM's offset by version.
This will solve the versioning issue caused by the new version of
secure memory of i.MX7

drivers/crypto/fsl: fix endianness issue in RNG

2015-12-15T00:57:35+00:00

For Setting and clearing the bits in SEC Block registers
sec_clrbits32() and sec_setbits32() are used which work as
per endianness of CAAM block.
So these must be used with SEC register address as argument.
If the value is read in a local variable, then the functions
will not behave correctly where endianness of CAAM and core is
different.
