wolfTPM is an open-source TPM 2.0 stack with backward API compatibility,
designed for embedded use. It is highly portable, and has native support
for Linux. wolfTPM has a compact code size with low resource usage.

[Thomas:
 - Fix ordering in the DEVELOPERS file, use full name
 - Add missing !BR2_STATIC_LIBS dependency
 - Use "select" and not "select on"
 - Make sure wolftpm-config script gets post-processed by using
   <pkg>_CONFIG_SCRIPTS
 - Add missing --with-wolfcrypt option.
 - Rename WOLFTPM_CONFIG_RPATH to WOLFTPM_TOUCH_CONFIG_RPATH and use
   mkdir -p to make the hook re-executable]
