Why This File Exists

CPU and platform-specific kernel glue: boot entry, traps, syscall entry, interrupts, page tables, context switch, and low-level barriers.

		  The EN751221 family includes EN7512, RN7513, EN7521, EN7526.
		  They are based on single core MIPS 34Kc processors. To boot
		  this kernel, you will need a device tree such as
		  MIPS_RAW_APPENDED_DTB=y, and a root filesystem.

		  The SmartFiber XP8421-B is a device based on the EN751221 SoC.
		  It has 512MB of memory and 256MB of NAND flash. This kernel
		  needs only an appended initramfs to boot. It can be loaded
		  through XMODEM and booted from memory in the bootloader, or
		  it can be packed in tclinux.trx format and written to flash.
