Subject: [U-Boot,1/3] vsprintf.c: Always enable CONFIG_SYS_VSNPRINTF

Enabling this function always removes some class of string saftey issues.
|
||||
The size change here in general is about 400 bytes and this seems a reasonable
|
||||
trade-off.

I ran my usual world build of buildman with size comparison options this time
|
||||
to test this out. The only exception to the general size change here are
|
||||
q8_a23_tablet_800x480 and gt90h_v4 both in the non-SPL case. These both grow
|
||||
by 3780 bytes in the non-SPL case. In all cases except those two, when paired
|
||||
with the gzwrite patch I posted yesterday we gain all of that back, or more.
