Tim Harvey 79e315761c board: gateworks: venice: update board doc to show other emmc parts
Update the venice board documentation to show how to install to the
various eMMC hardware partitions available as the same binary firmware
can be placed in either user/boot0/boot1 without build-time config
changes. Note that the boot offsets differ depending on the SoC and the
eMMC hardware partition.

=============
U-Boot for the Gateworks i.MX8M Mini Venice Development Kit boards
Quick Start
-----------
- Build the ARM Trusted firmware binary
- Get DDR firmware
- Build U-Boot
- Flash to eMMC
- Boot
Get and Build the ARM Trusted firmware
--------------------------------------
.. code-block:: bash
$ git clone https://github.com/nxp-imx/imx-atf.git -b lf_v2.4
$ make PLAT=imx8mm bl31 CROSS_COMPILE=aarch64-linux-gnu-
$ cp build/imx8mm/release/bl31.bin .
Get the DDR Firmware
--------------------
.. code-block:: bash
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.9.bin
$ chmod +x firmware-imx-8.9.bin
$ ./firmware-imx-8.9.bin
$ cp firmware-imx-8.9/firmware/ddr/synopsys/lpddr4*.bin .
Build U-Boot
------------
.. code-block:: bash
$ make imx8mm_venice_defconfig
$ make CROSS_COMPILE=aarch64-linux-gnu-
Update eMMC
-----------
.. code-block:: bash
=> tftpboot $loadaddr flash.bin
=> setexpr blkcnt $filesize + 0x1ff && setexpr blkcnt $blkcnt / 0x200
=> mmc dev 2 0 && mmc write $loadaddr 0x42 $blkcnt # emmc user hw part
=> mmc dev 2 1 && mmc write $loadaddr 0x42 $blkcnt # or emmc boot0 hw part
=> mmc dev 2 2 && mmc write $loadaddr 0x42 $blkcnt # or emmc boot1 hw part
