- The current startup sequence performs the call to the bsp_fdt_copy() and then
performs memset to the BSS region. In bsp_fdt_copy(), RTEMS allocates
memory for bsp_fdt_blob into BSS region which is yet to initialize. With
current startup sequence, the bsp_fdt_blob is getting erased after memset.
The proposed fix performs the BSS region memset operation and then performs a
call to the bsp_fdt_copy().
