CONFIG_SHA1 - support SHA1 hashing
CONFIG_SHA256 - support SHA256 hashing
CONFIG_SHA1 - This option enables support of hashing using SHA1
algorithm. The hash is calculated in software.
CONFIG_SHA256 - This option enables support of hashing using
SHA256 algorithm. The hash is calculated in software.
CONFIG_SHA_HW_ACCEL - This option enables hardware acceleration
for SHA1/SHA256 hashing.
This affects the 'hash' command and also the
hash_lookup_algo() function.
CONFIG_SHA_PROG_HW_ACCEL - This option enables
hardware-acceleration for SHA1/SHA256 progressive hashing.
Data can be streamed in a block at a time and the hashing
is performed in hardware.
Note: There is also a sha1sum command, which should perhaps
be deprecated in favour of 'hash sha1'.

Freescale ARM64 SoCs like LS2085A have ARM TrustZone components like
TZPC-BP147 (TrustZone Protection Controller) and TZASC-400 (TrustZone
Address Space Controller).
While most of the configuration related programming of these peripherals
is left to a root-of-trust security software layer (running in EL3
privilege mode), but still some configurations of these peripherals
might be required while the bootloader is executing in EL3 privilege
mode. The following sections define how to turn on these features for
LS2085A like SoCs.
TZPC-BP147 (TrustZone Protection Controller)
============================================
- Depends on CONFIG_FSL_TZPC_BP147 configuration flag.
- Separates Secure World and Normal World on-chip RAM (OCRAM) spaces.
- Provides a programming model to set access control policy via the TZPC
TZDECPROT Registers.
TZASC-400 (TrustZone Address Space Controller)
==============================================
- Depends on CONFIG_FSL_TZASC_400 configuration flag.
- Separates Secure World and Normal World external memory spaces for bus masters
such as processors and DMA-equipped peripherals.
- Supports 8 fully programmable address regions, initially inactive at reset,
and one base region, always active, that covers the remaining address space.
