menu "Library routines"
config CC_OPTIMIZE_LIBS_FOR_SPEED
bool "Optimize libraries for speed"
help
Enabling this option will pass "-O2" to gcc when compiling
under "lib" directory.
If unsure, say N.
config HAVE_PRIVATE_LIBGCC
bool
config USE_PRIVATE_LIBGCC
bool "Use private libgcc"
depends on HAVE_PRIVATE_LIBGCC
help
This option allows you to use the built-in libgcc implementation
of U-boot instead of the one privided by the compiler.
If unsure, say N.
config SYS_HZ
int
default 1000
help
The frequency of the timer returned by get_timer().
get_timer() must operate in milliseconds and this option must be
set to 1000.

menu "Hashing Support"
config SHA1
bool "Enable SHA1 support"
help
This option enables support of hashing using SHA1 algorithm.
The hash is calculated in software.
The SHA1 algorithm produces a 160-bit (20-byte) hash value
(digest).
config SHA256
bool "Enable SHA256 support"
help
This option enables support of hashing using SHA256 algorithm.
The hash is calculated in software.
The SHA256 algorithm produces a 256-bit (32-byte) hash value
(digest).
config SHA_HW_ACCEL
bool "Enable hashing using hardware"
help
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
bool "Enable Progressive hashing support using hardware"
depends on SHA_HW_ACCEL
help
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.
