1 menu "Library routines"
3 config CC_OPTIMIZE_LIBS_FOR_SPEED
4 bool "Optimize libraries for speed"
6 Enabling this option will pass "-O2" to gcc when compiling
11 config HAVE_PRIVATE_LIBGCC
14 config USE_PRIVATE_LIBGCC
15 bool "Use private libgcc"
16 depends on HAVE_PRIVATE_LIBGCC
18 This option allows you to use the built-in libgcc implementation
19 of U-boot instead of the one privided by the compiler.
26 The frequency of the timer returned by get_timer().
27 get_timer() must operate in milliseconds and this option must be
30 source lib/rsa/Kconfig
32 menu "Hashing Support"
35 bool "Enable SHA1 support"
37 This option enables support of hashing using SHA1 algorithm.
38 The hash is calculated in software.
39 The SHA1 algorithm produces a 160-bit (20-byte) hash value
43 bool "Enable SHA256 support"
45 This option enables support of hashing using SHA256 algorithm.
46 The hash is calculated in software.
47 The SHA256 algorithm produces a 256-bit (32-byte) hash value
51 bool "Enable hashing using hardware"
53 This option enables hardware acceleration
54 for SHA1/SHA256 hashing.
55 This affects the 'hash' command and also the
56 hash_lookup_algo() function.
58 config SHA_PROG_HW_ACCEL
59 bool "Enable Progressive hashing support using hardware"
60 depends on SHA_HW_ACCEL
62 This option enables hardware-acceleration for
63 SHA1/SHA256 progressive hashing.
64 Data can be streamed in a block at a time and the hashing
65 is performed in hardware.
