Hi guys,
We would like to share with you the cross reference search for TI u-boot at https://code-grep.com/view/project/54b59bdd3b2082545000000d/
You can do searching for definitions/references of variables/functions as well as quick popup when clicking on them.
Hopefully this would ease the pain of browsing huge source code like u-boot for you guys.
Feel free to drop us a note at contact@code-grep.com
