This patch modifies the baremetal code to include ipi related code. It moves the baremetal specific platform API from platform.c to baremetal.c. It also moves the platform specific information from baremetal.h to platform.h. The patch also updates license information in linker script Signed-off-by: Kinjal Pravinbhai Patel <patelki@xilinx.com>
