Subject: tdx-cfg-block: simplify i.MX 6 module detection
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=89315f319cd9016ede10448e611aa3f2c84188df;p=u-boot.git

tdx-cfg-block: simplify i.MX 6 module detection

Use CONFIG_TARGET_... at compile time to differentiate between
Apalis iMX6, Colibri iMX6 and Colibri iMX6ULL. Avoid code
duplication by moving question about Wi-Fi / Bluetooth before
IT/non-IT decision.
