Add KERNEL_EXTRA_ARGS parameter
With recent kernel versions, some ARM configurations need may fail to build with errors like this: multiple load addresses: 0x80008000 0x80008000 This is incompatible with uImages Specify LOADADDR on the commandline to build an uImage We cannot pass this information in EXTRA_OEMAKE, as "meta/classes/kernel.bbclass" explicitly ignores all EXTRA_OEMAKE settings. So add KERNEL_EXTRA_ARGS parameter so affected boards can add for example KERNEL_EXTRA_ARGS = "LOADADDR=0x80008000" to their configuration. We make this general enough so other needed command line options can be passed as well when compiling the kernel.
