Per Appendix A.7 in Q/LS 0013-2014 (龙芯CPU开发系统固件与内核接口规范 V2.2, lit. Loongson DevSys Firmware Kernel Interface Specification V2.2), interface_info.size is size of this interface, not size of the LEFI BIOS ROM.
In any case, the BIOS ROM Size just cannot be several kilobytes (KB) on Loongson64 LEFI platforms.
