Genode log test on i.MX8 EVK board

[jklmnn]

Building uBoot image:

• tool/create_builddir arm_v8a
• additions to etc/build.conf:

  RUN_OPT += --include image/uboot
  KERNEL ?= hw
  BOARD ?= imx8q_evk

• Custom uBoot: https://genode.org/documentation/release-notes/20.02#USB_and_Input
• uBoot configuration: https://genodians.org/tomga/2019-07-07-rpi-booting

To create a bootable SD card:

• create Genodes custom uBoot
• format the SD card with GPT and an ext4 partition starting with at least 2 MB offset
• move the uImage file created in var/run/<name>/uImage to the ext4 partition
• set the board to SD boot by setting the 4 switches to 1100
• boot
• in U-Boot:

  => ext4load mmc 1:1 ${loadaddr} uImage
  => bootm ${loadaddr}

  This should boot the Genode image. Example:

  
  u-boot=> ext4load mmc 1:1 ${loadaddr} /uImage
  875649 bytes read in 60 ms (13.9 MiB/s)
  u-boot=> bootm ${loadaddr}

To use this with the gart image, the load address has to be 0x60000000.
