Instead of selecting REGEX when NET is enabled, make it the default, but allow boards that are tiny to disable it and lose functionality on all but the first Ethernet adapter. cm-bf548, bf538f-ezkit, and bf533-stamp need this. None appear to have more than one Ethernet interface. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>

bool "Enable safe version of sprintf()"
|
|
help
|
|
Since sprintf() can overflow its buffer, it is common to use
|
|
snprintf() instead, which knows the buffer size and can avoid
|
|
overflow. However, this does increase code size slightly (for
|
|
Thumb-2, about 420 bytes). Enable this option for safety when
|
|
using sprintf() with data you do not control.
