+Booting Linux/LoongArch
+=======================
+
+:Author: Yanteng Si <siyanteng@loongson.cn>
+:Date:   18 Nov 2022
+
+Information passed from BootLoader to kernel
+============================================
+
+LoongArch supports ACPI and FDT. The information that needs to be passed
+to the kernel includes the memmap, the initrd, the command line, optionally
+the ACPI/FDT tables, and so on.
+
+The kernel is passed the following arguments on `kernel_entry` :
+
+      - a0 = efi_boot: `efi_boot` is a flag indicating whether
+        this boot environment is fully UEFI-compliant.
+
+      - a1 = cmdline: `cmdline` is a pointer to the kernel command line.
+
+      - a2 = systemtable: `systemtable` points to the EFI system table.
+        All pointers involved at this stage are in physical addresses.
+
+Header of Linux/LoongArch kernel images
+=======================================
+
+Linux/LoongArch kernel images are EFI images. Being PE files, they have
+a 64-byte header structured like::
+
+	u32	MZ_MAGIC                /* "MZ", MS-DOS header */
+	u32	res0 = 0                /* Reserved */
+	u64	kernel_entry            /* Kernel entry point */
+	u64	_end - _text            /* Kernel image effective size */
+	u64	load_offset             /* Kernel image load offset from start of RAM */
+	u64	res1 = 0                /* Reserved */
+	u64	res2 = 0                /* Reserved */
+	u64	res3 = 0                /* Reserved */
+	u32	LINUX_PE_MAGIC          /* Magic number */
+	u32	pe_header - _head       /* Offset to the PE header */

+====================
+
+:作者: 司延腾 <siyanteng@loongson.cn>
+:日期: 2022年11月18日
+
+BootLoader传递给内核的信息
+==========================
+
+LoongArch支持ACPI和FDT启动，需要传递给内核的信息包括memmap、initrd、cmdline、可
+选的ACPI/FDT表等。
+
+内核在 `kernel_entry` 入口处被传递以下参数:
+
+      - a0 = efi_boot: `efi_boot` 是一个标志，表示这个启动环境是否完全符合UEFI
+        的要求。
+
+      - a1 = cmdline: `cmdline` 是一个指向内核命令行的指针。
+
+      - a2 = systemtable: `systemtable` 指向EFI的系统表，在这个阶段涉及的所有
+        指针都是物理地址。
+
+Linux/LoongArch内核镜像文件头
+=============================
+
+内核镜像是EFI镜像。作为PE文件，它们有一个64字节的头部结构体，如下所示::
+
+	u32	MZ_MAGIC                /* "MZ", MS-DOS 头 */
+	u32	res0 = 0                /* 保留 */
+	u64	kernel_entry            /* 内核入口点 */
+	u64	_end - _text            /* 内核镜像有效大小 */
+	u64	load_offset             /* 加载内核镜像相对内存起始地址的偏移量 */
+	u64	res1 = 0                /* 保留 */
+	u64	res2 = 0                /* 保留 */
+	u64	res3 = 0                /* 保留 */
+	u32	LINUX_PE_MAGIC          /* 魔术数 */
+	u32	pe_header - _head       /* 到PE头的偏移量 */
