Handle 0x0000, DMI type 0, 26 bytes BIOS Information Vendor: Loongson Version: vUDK2018-LoongArch-V2.0.pre-beta8 Release Date: 06/15/2022 ROM Size: 4 MB According to "BIOS Information (Type 0) structure" in the SMBIOS Reference Specification [1], it shows 64K * (n+1) is the size of the physical device containing the BIOS if the size is less than 16M. Additionally, we can see the related code in dmidecode [2]: u64 s = { .l = (code1 + 1) << 6 }; So the output of dmidecode is correct, the output of boardinfo is wrong, fix it. By the way, at present no need to consider the size is 16M or greater on LoongArch, because it is usually 4M or 8M which is enough to use.

That's the reason why fcsr cannot be modified by ptrace. This patch fixs this problem and allows users using ptrace to modify the fcsr.

So fix it by multiplying nodes_per_package.
