For the "linux-imx" kernel, the package "linux-imx-rt" recipe defines a new variant of the kernel, but I don't understand how this can be used in a build. In other words, do you specify PREFERRED_PROVIDER_virtual/kernel="linux-imx-rt" or PREFERRED_VERSION_virtual/kernel_linux-imx="rt-3.10.17" Please advise, Eric
