For arm - Fix the cross-prelink (no patches available) or - Fix glibc (as proposed by Szabolcs) 2. For aarch64 - Try to upstream patches from Joseph to OE/Yocto's cross-prelink or - Fix glibc (if required) or - Do nothing (aarch64 will not be prelinked in OE/Yocto, which means that it will work correctly) Best regards, Lukasz Majewski -- DENX Software Engineering GmbH, Managing Director: Wolfgang Denk HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-59 Fax: (+49)-8142-66989-80 Email: lu...@denx.de
