-----------------------------------------
-Qemu is a full system emulator. See
-
-http://www.nongnu.org/qemu/
-
-Limitations & comments
-----------------------
-Supports the "-M mips" configuration of qemu: serial,NE2000,IDE.
-Supports little and big endian as well as 32 bit and 64 bit.
-Derived from au1x00 with a lot of things cut out.
-
-Supports emulated flash (patch Jean-Christophe PLAGNIOL-VILLARD) with
-recent qemu versions. When using emulated flash, launch with
--pflash <filename> and erase mips_bios.bin.
-
-
-
-Notes for the Qemu MIPS port
-----------------------------
-
-I) Example usage:
-
-Using u-boot.bin as ROM (replaces Qemu monitor):
-
-32 bit, big endian:
-# make qemu_mips
-# qemu-system-mips -M mips -bios u-boot.bin -nographic
-
-32 bit, little endian:
-# make qemu_mipsel
-# qemu-system-mipsel -M mips -bios u-boot.bin -nographic
-
-64 bit, big endian:
-# make qemu_mips64
-# qemu-system-mips64 -cpu MIPS64R2-generic -M mips -bios u-boot.bin -nographic
-
-64 bit, little endian:
-# make qemu_mips64el
-# qemu-system-mips64el -cpu MIPS64R2-generic -M mips -bios u-boot.bin -nographic
-
-or using u-boot.bin from emulated flash:
-
-if you use a qemu version after commit 4224
-
-create image:
-# dd of=flash bs=1k count=4k if=/dev/zero
-# dd of=flash bs=1k conv=notrunc if=u-boot.bin
-start it (see above):
-# qemu-system-mips[64][el] [-cpu MIPS64R2-generic] -M mips -pflash flash -nographic
-
-2) Download kernel + initrd
-
-On ftp://ftp.denx.de/pub/contrib/Jean-Christophe_Plagniol-Villard/qemu_mips/
-you can downland
-
-#config to build the kernel
-qemu_mips_defconfig
-#patch to fix mips interrupt init on 2.6.24.y kernel
-qemu_mips_kernel.patch
-initrd.gz
-vmlinux
-vmlinux.bin
-System.map
-
-4) Generate uImage
-
-# tools/mkimage -A mips -O linux -T kernel -C gzip -a 0x80010000 -e 0x80245650 -n "Linux 2.6.24.y" -d vmlinux.bin.gz uImage
-
-5) Copy uImage to Flash
-# dd if=uImage bs=1k conv=notrunc seek=224 of=flash
-
-6) Generate Ide Disk
-
-# dd of=ide bs=1k cout=100k if=/dev/zero
-
-# sfdisk -C 261 -d ide
-# partition table of ide
-unit: sectors
-
-     ide1 : start=       63, size=    32067, Id=83
-     ide2 : start=    32130, size=    32130, Id=83
-     ide3 : start=    64260, size=  4128705, Id=83
-     ide4 : start=        0, size=        0, Id= 0
-
-7) Copy to ide
-
-# dd if=uImage bs=512 conv=notrunc seek=63 of=ide
-
-8) Generate ext2 on part 2 on Copy uImage and initrd.gz
-
-# Attached as loop device ide offset = 32130 * 512
-# losetup -o 16450560 -f ide
-# Format as ext2 ( arg2 : nb blocks)
-# mke2fs /dev/loop0 16065
-# losetup -d /dev/loop0
-# Mount and copy uImage and initrd.gz to it
-# mount -o loop,offset=16450560 -t ext2 ide /mnt
-# mkdir /mnt/boot
-# cp {initrd.gz,uImage} /mnt/boot/
-# Umount it
-# umount /mnt
-
-9) Set Environment
-
-setenv rd_start 0x80800000
-setenv rd_size 2663940
-setenv kernel BFC38000
-setenv oad_addr 80500000
-setenv load_addr2 80F00000
-setenv kernel_flash BFC38000
-setenv load_addr_hello 80200000
-setenv bootargs 'root=/dev/ram0 init=/bin/sh'
-setenv load_rd_ext2 'ide res; ext2load ide 0:2 ${rd_start} /boot/initrd.gz'
-setenv load_rd_tftp 'tftp ${rd_start} /initrd.gz'
-setenv load_kernel_hda 'ide res; diskboot ${load_addr} 0:2'
-setenv load_kernel_ext2 'ide res; ext2load ide 0:2 ${load_addr} /boot/uImage'
-setenv load_kernel_tftp 'tftp ${load_addr} /qemu_mips/uImage'
-setenv boot_ext2_ext2 'run load_rd_ext2; run load_kernel_ext2; run addmisc; bootm ${load_addr}'
-setenv boot_ext2_flash 'run load_rd_ext2; run addmisc; bootm ${kernel_flash}'
-setenv boot_ext2_hda 'run load_rd_ext2; run load_kernel_hda; run addmisc; bootm ${load_addr}'
-setenv boot_ext2_tftp 'run load_rd_ext2; run load_kernel_tftp; run addmisc; bootm ${load_addr}'
-setenv boot_tftp_hda 'run load_rd_tftp; run load_kernel_hda; run addmisc; bootm ${load_addr}'
-setenv boot_tftp_ext2 'run load_rd_tftp; run load_kernel_ext2; run addmisc; bootm ${load_addr}'
-setenv boot_tftp_flash 'run load_rd_tftp; run addmisc; bootm ${kernel_flash}'
-setenv boot_tftp_tftp 'run load_rd_tftp; run load_kernel_tftp; run addmisc; bootm ${load_addr}'
-setenv load_hello_tftp 'tftp ${load_addr_hello} /examples/hello_world.bin'
-setenv go_tftp 'run load_hello_tftp; go ${load_addr_hello}'
-setenv addmisc 'setenv bootargs ${bootargs} console=ttyS0,${baudrate} rd_start=${rd_start} rd_size=${rd_size} ethaddr=${ethaddr}'
-setenv bootcmd 'run boot_tftp_flash'
-
-10) Now you can boot from flash, ide, ide+ext2 and tfp
-
-# qemu-system-mips -M mips -pflash flash -monitor null -nographic -net nic -net user -tftp `pwd` -hda ide
-
-II) How to debug U-Boot
-
-In order to debug U-Boot you need to start qemu with gdb server support (-s)
-and waiting the connection to start the CPU (-S)
-
-# qemu-system-mips -S -s -M mips -pflash flash -monitor null -nographic -net nic -net user -tftp `pwd` -hda ide
-
-in an other console you start gdb
-
-1) Debugging of U-Boot Before Relocation
-
-Before relocation, the addresses in the ELF file can be used without any problems
-by connecting to the gdb server localhost:1234
-
-# mipsel-unknown-linux-gnu-gdb u-boot

-
-2) Debugging of U-Boot After Relocation
-
-For debugging U-Boot after relocation we need to know the address to which
-U-Boot relocates itself to 0x87fa0000 by default.
-And replace the symbol table to this offset.
-
-(gdb) symbol-file
-Discard symbol table from `/private/u-boot-arm/u-boot'? (y or n) y
-Error in re-setting breakpoint 1:
-No symbol table is loaded.  Use the "file" command.
-No symbol file now.
