| XSK_EFUSEPS_SPK_ID | Default = 00000000 The value mentioned in this will be converted to hex buffer and written into the Zynq UltraScale+ MPSoC PS eFUSE array when write API used. This value should be given in string format. It should be 8 characters long, valid characters are 0-9,a-f,A-F. Any other character is considered as invalid string and will not burn SPK ID.
