是不是口误了哈哈哈，direct linux boot 根本不需要 legacy multiboot？但是qemu要求内核支持 legacy multiboot 吗？ |

完成了legacy multiboot引导的支持：
需要注意的是，这个PR并不意味着能通过legacy multiboot启动DragonOS进入到用户态。原因是legacy multiboot的协议没有提供rsdp表的信息。因此会在acpi初始化的时候报错（如下图所示）。
要解决这个问题，那么可以通过完善内核的UEFI支持，通过uefi的system table来获取rsdp的信息。（但是目前只实现了riscv64下的uefi支持）。
我正在开发对direct linux boot的支持，而qemu必须要求内核能通过legacy multiboot启动，所以我才搞了这个PR，虽然direct linux boot根本不需要使用direct linux boot...我也觉得很神奇。
由于legacy multiboot支持不是很急切，因此上述的解决方案（通过UEFI获取rsdp表），这个就暂时不急了。
