Subject: [PATCH] MIPS: Loongson64: remove ROM Size unit in boardinfo
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

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.
