Fixed ACPI conflict with SMBus

  • Two options to add the acpi_enforce_resources=lax into kernel cmdline.
 1. modify the BOOTX64.conf under EFI/BOOT directly on your bootable disk
 2. modify grub-usb.conf and the rest grub-xx.conf under 
    Project/layers/wr-idp/wr-idp-devkit/recipes-uefi/grub-efi/files/grub-conf 
    for your image just add acpi_enforce_resources=lax behind /bzImage
  • Two options to load i2c-dev by default
  1. add modprobe i2c-dev in /etc/rc.local
  2. make i2c-dev as built-in driver instead of kernel module
