From: Kexy Biscuit <kexybiscuit@xxxxxxx>
commit bd2212d658d7659b9d83c7e2f3a06789d4db1e90 upstream.
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.
