 Building and Running Zephyr tests
 =================================
-Presently only toolchains for ARM and x86 are supported.
+Presently only toolchains for ARM, x86, IAMCU and Nios2 are supported.
 (For ARM we use CortexM3 toolchain)
 
-Default Zephyr BOARD is selected as follows:
-
-BOARD_arm ?= "qemu_cortex_m3"
-BOARD_x86 ?= "qemu_x86"

 You can build and test an individual existing Zephyr test.
 This is done by appending the actual test name to the "zephyr-kernel-test",
 for example:
 
-    $ MACHINE=qemux86 bitbake zephyr-kernel-test-test_sleep
-    $ MACHINE=qemux86 bitbake zephyr-kernel-test-test_sleep -ctestimage
