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
default y if HAVE_PRIVATE_LIBGCC && ((ARM && !ARM64) || MIPS)
help
This option allows you to use the built-in libgcc implementation
of U-Boot instead of the one provided 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.
config USE_TINY_PRINTF
bool "Enable tiny printf() version"
help
This option enables a tiny, stripped down printf version.
This should only be used in space limited environments,
like SPL versions with hard memory limits. This version
reduces the code size by about 2.5KiB on armv7.
The supported format specifiers are %c, %s, %u/%d and %x.
config REGEX
bool "Enable regular expression support"
default y if NET
help
If this variable is defined, U-Boot is linked against the
SLRE (Super Light Regular Expression) library, which adds
regex support to some commands, for example "env grep" and
"setexpr".
config LIB_RAND
bool "Pseudo-random library support "
help
This library provides pseudo-random number generator functions.
config SPL_TINY_MEMSET
bool "Use a very small memset() in SPL"
help
The faster memset() is the arch-specific one (if available) enabled
by CONFIG_USE_ARCH_MEMSET. If that is not enabled, we can still get
better performance by writing a word at a time. But in very
size-constrained envrionments even this may be too big. Enable this
option to reduce code size slightly at the cost of some speed.
config RBTREE
bool
source lib/dhry/Kconfig
menu "Security support"
config AES
bool "Support the AES algorithm"
help
This provides a means to encrypt and decrypt data using the AES
(Advanced Encryption Standard). This algorithm uses a symetric key
and is widely used as a streaming cipher. Different key lengths are
supported by the algorithm but only a 128-bit key is supported at
present.
source lib/rsa/Kconfig
config TPM
bool "Trusted Platform Module (TPM) Support"
depends on DM
help
This enables support for TPMs which can be used to provide security
features for your board. The TPM can be connected via LPC or I2C
and a sandbox TPM is provided for testing purposes. Use the 'tpm'
command to interactive the TPM. Driver model support is provided
for the low-level TPM interface, but only one TPM is supported at
a time by the TPM library.

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.
config MD5
bool
endmenu
menu "Compression Support"
config LZ4
bool "Enable LZ4 decompression support"
help
If this option is set, support for LZ4 compressed images
is included. The LZ4 algorithm can run in-place as long as the
compressed image is loaded to the end of the output buffer, and
trades lower compression ratios for much faster decompression.
NOTE: This implements the release version of the LZ4 frame
format as generated by default by the 'lz4' command line tool.
This is not the same as the outdated, less efficient legacy
frame format currently (2015) implemented in the Linux kernel
(generated by 'lz4 -l'). The two formats are incompatible.
config LZO
bool

config ERRNO_STR
bool "Enable function for getting errno-related string message"
help
The function errno_str(int errno), returns a pointer to the errno
corresponding text message:
- if errno is null or positive number - a pointer to "Success" message
- if errno is negative - a pointer to errno related message
config OF_LIBFDT
bool "Enable the FDT library"
default y if OF_CONTROL
help
This enables the FDT library (libfdt). It provides functions for
accessing binary device tree images in memory, such as adding and
removing notes and properties, scanning through the tree and finding
particular compatible nodes. The library operates on a flattened
version of the device tree.
config OF_LIBFDT_OVERLAY
bool "Enable the FDT library overlay support"
help
This enables the FDT library (libfdt) overlay support.
config SPL_OF_LIBFDT
bool "Enable the FDT library for SPL"
default y if SPL_OF_CONTROL
help
This enables the FDT library (libfdt). It provides functions for
accessing binary device tree images in memory, such as adding and
removing notes and properties, scanning through the tree and finding
particular compatible nodes. The library operates on a flattened
version of the device tree.
config FDT_FIXUP_PARTITIONS
bool "overwrite MTD partitions in DTS through defined in 'mtdparts'"

help
Allow overwriting defined partitions in the device tree blob
using partition info defined in the 'mtdparts' environment
variable.

help
The System Management BIOS (SMBIOS) specification addresses how
motherboard and system vendors present management information about
their products in a standard format by extending the BIOS interface
on Intel architecture systems.
