+- Enable POVDD
+  -- Refer board GSG(Getting Started Guide) for the steps to enable POVDD.
+  -- Once the POVDD is enabled, make sure to set variable POVDD_ENABLE := yes, in the platform.mk.

+      Note: SRK Hash should be carefully written keeping in mind the SFP Block Endianness.
+
+- At U-Boot prompt, verify that SNVS registers for OTPMK are correctly written:
+
+  --  Check for the OTPMK.
+   .. code:: shell
+
+        md $SNVS_HPSR_REG
+
+      Command Output:
+          01e90014: 80000900
+
+          OTPMK_ZERO_BIT is zero, indicating that the OTPMK is blown.
+
+          Note: In case it is read as 00000000, then read this register using jtag (in development mode only through CW tap).
+
+   .. code:: shell

+          01e80244: ffffffff ffffffff ffffffff ffffffff    ................
+
+          Note: OTPMK will never be visible in plain.
+
+  --  Check for the SRK Hash. For example, if following SRK hash is written:
+
+       SFP SRKHR0 = fdc2fed4
+       SFP SRKHR1 = 317f569e
+       SFP SRKHR2 = 1828425c

+       SFP SRKHR5 = df792a70
+       SFP SRKHR6 = 2dff85e1
+       SFP SRKHR7 = 32a29687,
+
+       then following would be the value on dumping SRK hash.
+
+   .. code:: shell
+
+        md $SRKHR0 0x10
+
+      Command Output:

+
+          Note: SRK Hash is visible in plain based on the SFP Block Endianness.
+
+- Caution: Donot proceed to the next step, until you are sure that OTPMK and SRKH are correctly blown from above steps.
+  -- After the next step, there is no turning back.
+  -- Fuses will be burnt, which cannot be undo.
+
+- Write SFP_INGR[INST] with the PROGFB(0x2) instruction to blow the fuses.
+  -- User need to save the SRK key pair and OTPMK Key forever, to continue using this board.

+
+Second method to do the fuse provsioning:
+=========================================
+
+This method is used for quick way to provision fuses.
+Typically used by those who needs to provision number of boards.
+
+- Enable POVDD:
+  -- Refer the table above to enable POVDD.
+
+     Note: If GPIO Pin supports enabling POVDD, it can be done through the below input_fuse_file.
+
+  -- Once the POVDD is enabled, make sure to set variable POVDD_ENABLE := yes, in the platform.mk.
+
+- User need to populate the "input_fuse_file", corresponding to the platform for:
+
+  -- OTPMK
+  -- SRKH
+
+  Table of fuse provisioning input file for every supported platform:
+

+
+- Create the TF-A binary with FUSE_PROG=1.

+
+- Deployment:
+  -- Refer the nxp-layerscape.rst for deploying TF-A images.
+  -- Deploying fip_fuse.bin:
+
+       For Flexspi-Nor:
+
+   .. code:: shell
+
+        tftp 82000000  $path/fuse_fip.bin;

+
+      For SD or eMMC [file_size_in_block_sizeof_512 = (Size_of_bytes_tftp / 512)]:
+
+   .. code:: shell
+
+        tftp 82000000  $path/fuse_fip.bin;
+        mmc write 82000000 0x4408 <file_size_in_block_sizeof_512>;

+
+      Note:
+       - 0x00000000 shows no error, then fuse provisioning is successful.
