+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".

+ 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

+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+ This is not the same as the outdated, less efficient legacy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 OF_LIBFDT
+ bool "Enable the FDT library"
+ default y if OF_CONTROL
+ help
+ This enables the FDT library (libfdt). It provides functions for
