+This Malta target is intended to be used with the Qemu emulator. It can be used
+to prototype an OpenWrt firmware for MIPS processors. One could also use it to
+troubleshoot MIPS applications without access to real hardware.
+
+To use the images built by OpenWrt with qemu, use the following commands:
+
+For the little-endian image:
+qemu-system-mipsel -kernel bin/malta/openwrt-malta-le-vmlinux-initramfs.elf -nographic -m 256
+
+For the big-endian image:
+qemu-system-mips -kernel bin/malta/openwrt-malta-be-vmlinux-initramfs.elf -nographic -m 256
+
+and enjoy the system bootin.

+Subject: [PATCH 330/331] MIPS: Malta: Mark kernel code and kernel data
+ segments as BOOT_MEM_RAM.
+
+Kexec-tools requires those segments listed as "System RAM" in
+/proc/iomem, otherwise, an error message of "Invalid memory segment"
+will be emitted when trying to load the ELF kernel image.
