15	bool "Use private libgcc"
16	depends on HAVE_PRIVATE_LIBGCC
17	help
18	  This option allows you to use the built-in libgcc implementation
19	  of U-boot instead of the one privided by the compiler.
20	  If unsure, say N.

34config SHA1
35	bool "Enable SHA1 support"
36	help
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
40	  (digest).
41
42config SHA256
43	bool "Enable SHA256 support"
44	help
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
48	  (digest).

50config SHA_HW_ACCEL
51	bool "Enable hashing using hardware"
52	help
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.
57
58config SHA_PROG_HW_ACCEL
59	bool "Enable Progressive hashing support using hardware"
60	depends on SHA_HW_ACCEL
61	help
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.
