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
