[U-Boot-Users] u-boot-1.0 and clearing of BSS segment on ARM
Hi folks,
I wonder why there seems to be no BSS clearing function for the SMDK2410 and other ARM platforms like in i386/start.s:bss
Is it assumed that the memory is already cleared on reset?

Hi,
hardware-reset does not clear the contents of RAM, so such function is certainly needed.
This morning I submitted a patch which - among other things - added BSS clearing to all ARMs, so there's hope that the problem will disappear soon :-)
Cheers Anders

We inherited this from the ARMboot port, and so far nobody fixed it - but see the recent patches by Anders larsen on this list.

I don't know what the guys who implemented this assumed. The code as is is broken.
Best regards,
