Subject: arm: mach-sc5xx: Remove manual bss_clear
X-Git-Tag: v2025.07-rc1~18^2~49^2~1
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3ce975ab888b583cb5816b1aa453136ea9549a3c;p=pandora-u-boot.git

arm: mach-sc5xx: Remove manual bss_clear

The arm library includes an implementation of bss_clear that is already
called from crt0.S. This re-clearing of BSS should not be performed in
the machine code and should therefore be removed.
