... and while we are at it,
                        for (miter = 0, s = optrom, d = dwptr;
                            miter < OPTROM_BURST_DWORDS; miter++, s++, d++)
                                *s = cpu_to_le32(*d);

                        ret = qla2x00_load_ram(ha, optrom_dma,
                            flash_data_to_access_addr(faddr),
                            OPTROM_BURST_DWORDS);

in qla24xx_write_flash_data() looks bloody odd.  We have dwptr pointing
to fixed-endian data, so conversion gets us host-endian and then we pass
the area filled with results of conversion for DMA?

And yes, dwptr points to fixed-endian - it comes from
qla24xx_write_optrom_data(struct scsi_qla_host *ha, uint8_t *buf,
    uint32_t offset, uint32_t length)
{
...
        rval = qla24xx_write_flash_data(ha, (uint32_t *)buf, offset >> 2,
            length >> 2);

Comments?
