106 To boot a kernel directly from a Linux build tree:
111         -kernel arch/arm/boot/zImage \
112         -dtb arch/arm/boot/dts/aspeed-ast2600-evb.dtb \
118 The machine options specific to Aspeed to boot from a flash image are :
120  * ``execute-in-place`` which emulates the boot from the CE0 flash
125    support for the chip model to boot.
129 To boot the machine from the flash image, use an MTD drive :
169 The machine options specific to Aspeed machines to boot from an eMMC
172  * ``boot-emmc`` to set or unset boot from eMMC (AST2600).
175 boot from an eMMC device. In this case, the machine assumes that the
176 eMMC image includes special boot partitions. Such an image can be
182    $ dd if=u-boot-spl.bin of=mmc-bootarea.img conv=notrunc
183    $ dd if=u-boot.bin of=mmc-bootarea.img conv=notrunc count=64 bs=1K
195 The ``boot-emmc`` option can be set or unset, to change the default
196 boot mode of machine: SPI or eMMC. This can be useful to boot the
198 boot the ``rainier-bmc`` machine from a flash device (default being
201 As an example, here is how to to boot the ``rainier-bmc`` machine from
202 the flash device with ``boot-emmc=false`` and let the machine use an
207    $ qemu-system-arm -M rainier-bmc,boot-emmc=false \
213 boot partitions, otherwise the contents will not be accessible to the
223    -device emmc,bus=sdhci-bus.2,drive=emmc0,boot-partition-size=1048576,boot-config=8
234    machines use the ``UART5`` device for a boot console, which is
238 To change the boot console and use device ``UART3`` (``/dev/ttyS2``
313 Manual boot using ``-device loader``:
321   UBOOT_SIZE=$(stat --format=%s -L ${IMGDIR}/u-boot-nodtb.bin)
324        -device loader,force-raw=on,addr=0x400000000,file=${IMGDIR}/u-boot-nodtb.bin \
325        -device loader,force-raw=on,addr=$((0x400000000 + ${UBOOT_SIZE})),file=${IMGDIR}/u-boot.dtb \
336 Boot using a virtual boot ROM (``-bios``):
349 image to be loaded during boot. This will load the vbootrom image from the
363 Steps to boot the AST2700fc machine:
367  * u-boot-nodtb.bin
368  * u-boot.dtb
380   UBOOT_SIZE=$(stat --format=%s -L ${IMGDIR}/u-boot-nodtb.bin)
383        -device loader,force-raw=on,addr=0x400000000,file=${IMGDIR}/u-boot-nodtb.bin \
