I added this to the begin of "ltq_mtd_probe" function:

bool mtd_addr_swap;

        if ( ltq_ebu_r32(LTQ_EBU_BUSCON0) & EBU_ENDIAN_SWAP ) {
                switch (ltq_soc_type()) {
                        case SOC_TYPE_VR9_2 :
                        case SOC_TYPE_AR10 :
                                mtd_addr_swap = false;
                                break;
                        default :
                                mtd_addr_swap = true;
                }
        } else mtd_addr_swap = true;


It's easier to add other architectures as needed. I tried it on my
OpenWrt release, and got it working fine. Is it correct in this way ?
