This patch add support of hsdk platform-specific commands: hsdk_clock set - set clock from axi_freq, cpu_freq and tun_freq environment variables/command line arguments hsdk_clock get - save clock frequencies to axi_freq, cpu_freq and tun_freq environment variables hsdk_clock print - show CPU, AXI, DDR and TUNNEL current clock frequencies. hsdk_clock print_all - show all currently used clock frequencies. hsdk_init - setup board HW in one of pre-defined configuration (hsdk_hs34 / hsdk_hs36 / hsdk_hs36_ccm / hsdk_hs38 / hsdk_hs38_ccm / hsdk_hs38x2 / hsdk_hs38x3 / hsdk_hs38x4) hsdk_go - run baremetal application on hsdk configured by hsdk_init command. This patch changes default behaviour of 'bootm' command: now we are able to set number of CPUs to be kicked by setting 'core_mask' environment variable before 'bootm' command run.
