crypto: fsl_hash: fix flush dcache alignment in caam_hash()
Loading a FIT kernel image with hash hardware acceleration enabled
(CONFIG_SHA_HW_ACCEL=y) displays the following CACHE warning:
[...]
Trying 'kernel-1' kernel subimage
[...]
Verifying Hash Integrity ... sha256CACHE: Misaligned operation at
range [16000128, 1673fae8]
[...]
Trying 'ramdisk-1' ramdisk subimage
[...]
Verifying Hash Integrity ... sha256CACHE: Misaligned operation at
range [1676d6d4, 1737a5d4]
[...]
Trying 'fdt-imx6q-xxx.dtb' fdt subimage
[...]
Verifying Hash Integrity ... sha256CACHE: Misaligned operation at
range [1673fbdc, 1674b0dc]
[...]
This patch fixes it.
Tested on:
- i.MX 6 custom board
- LS1021A custom board
