The concept of BSS for using uninitialized data (meaning: implicitely initialized to zero)
However, with the current u-boot linker scripts (some of them, at least; I'm not going to make a sweeping statement about all 270), data *explicitly* initialized to zero is also going in the bss. Combined with the fact that some C code is executed before the bss is cleared, that is simply evil.
is as old as C and Unix, actualy even older than that (from IBM 7090 times, IIRC). It is simple, efficient, and powerful.
Your point being? I'm not attacking the concept of a bss, just the use of it in a codebase where C code is executed prior to being able to clear the bss.
I see zero reason to drop it.
I have stated the reason. If you prefer an environment that invites bugs and ugly workarounds thereto, then suit yourself.
