Subject: Fixes bug clearing the bss section for i386
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=644e6fb4eb8be90ea04ba34b643a8bf019d680e0;p=u-boot.git

Fixes bug clearing the bss section for i386

Hi,
There is a bug in the code of clearing the bss section for processor
i386.(File: cpu/i386/start.S)
In the code, bss_start addr (starting addr of bss section) is put into
the register %eax, but the code which clears the bss section refers to
the addr pointed by %edi.

This patch fixes this bug by putting bss_start into %edi register.
