+ * are enabled in any given DTS).  This function maps from a DT-node back
+ * onto a BOOT_DEVICE_... constant, considering the currently active devices.
+ *
+ * Returns
+ *   -ENOENT, if no device matching the node could be found
+ *   -ENOSYS, if the device matching the node can not be mapped onto a
+ *            SPL boot device (e.g. the third MMC device)

-	bool "Support swapping dtbs at a later point in boot"
-	depends on FIT_EMBED
-	help
-	  It is possible during initial boot you may need to use a generic
-	  dtb until you can fully determine the board your running on. This
-	  config allows boards to implement a function at a later point
-	  during boot to switch to the "correct" dtb.
-
-config FIT_EMBED
-	bool "Support a FIT image embedded in the U-boot image"
-	help
-	  This option provides hooks to allow U-boot to parse an
-	  appended FIT image and enable board specific code to then select
-	  the correct DTB to be used.

+MULTI DTB FIT and SPL_MULTI_DTB_FIT
+
+The purpose of this feature is to enable U-Boot or the SPL to select its DTB
+from a FIT appended at the end of the binary.
+It comes in two flavors: U-Boot (CONFIG_MULTI_DTB_FIT) and SPL
+(CONFIG_SPL_MULTI_DTB_FIT).
+
+U-Boot flavor:
+Usually the DTB is selected by the SPL and passed down to U-Boot. But some
+platforms don't use the SPL. In this case MULTI_DTB_FIT can used to provide
+U-Boot with a choice of DTBs.
+The relevant DTBs are packed into a FIT (list provided by CONFIG__OF_LIST). The
+FIT is automatically generated at the end of the compilation and appended to
+u-boot.bin so that U-Boot can locate it and select the correct DTB from inside
+the FIT.
+The selection is done using board_fit_config_name_match() (same as what the SPL
+uses to select the DTB for U-Boot). The selection happens during fdtdec_setup()
+which is called during before relocation by board_init_f().
+
+SPL flavor:
+the SPL uses only a small subset of the DTB and it usually depends more
+on the SOC than on the board. So it's usually fine to include a DTB in the
+SPL that doesn't exactly match the board. There are howerver some cases
+where it's not possible. In the later case, in order to support multiple
+boards (or board revisions) with the same SPL binary, SPL_MULTI_DTB_FIT
+can be used.
+The relevant DTBs are packed into a FIT. This FIT is automatically generated
+at the end of the compilation, compressed and appended to u-boot-spl.bin, so
+that SPL can locate it and select the correct DTB from inside the FIT.
+CONFIG_SPL__OF_LIST is used to list the relevant DTBs.
+The compression stage is optional but reduces the impact on the size of the
+SPL. LZO and GZIP compressions are supported. By default, the area where the
+FIT is uncompressed is dynamicaly allocated but this behaviour can be changed
+for platforms that don't provide a HEAP big enough to contain the uncompressed
+FIT.
+The SPL uses board_fit_config_name_match() to find the correct DTB within the
+FIT (same as what the SPL uses to select the DTB for U-Boot).
+Uncompression and selection stages happen in fdtdec_setup() which is called
+during the early initialization stage of the SPL (spl_early_init() or
+spl_init())
+
+Impacts and performances (SPL flavor):
+The impact of this option is relatively small. Here are some numbers measured
+for a TI DRA72 platform:

+Booting from an SD card on RK3288 with TPL
+==========================================
+
+Since the size of SPL can't be exceeded 0x8000 bytes in RK3288, it is not possible add
+new SPL features like Falcon mode or etc.
+
+So introduce TPL so-that adding new features to SPL is possible because now TPL should
+run minimal with code like DDR, clock etc and rest of new features in SPL.
+
+As of now TPL is added on Vyasa-RK3288 board.
+
+To write an image that boots from an SD card (assumed to be /dev/mmcblk0):
+
+   ./tools/mkimage -n rk3288 -T rksd -d ./tpl/u-boot-tpl.bin out &&
+    cat ./spl/u-boot-spl-dtb.bin >> out &&
+    sudo dd if=out of=/dev/mmcblk0 seek=64 &&
+    sudo dd if=u-boot-dtb.img of=/dev/mmcblk0 seek=256

+A special specifier "same-as-spl" can be used at any position in the
+boot-order to direct U-Boot to insert the device the SPL was booted
+from there.  Whether this is indeed inserted or silently ignored (if
+it is not supported on any given SoC/board or if the boot-device is
+not available to continue booting from) is implementation-defined.
+Note that if "same-as-spl" expands to an actual node for a given
+board, the corresponding node may appear multiple times in the
+boot-order (as there currently exists no mechanism to suppress
+duplicates from the list).

+       detecting the absence of a lookahead is sufficient to determine
+       that there is no unexpected or expected token to report.  In that
+       case, just report a simple "syntax error".
+     - Don't assume there isn't a lookahead just because this state is a
+       consistent state with a default action.  There might have been a
+       previous inconsistent state, consistent state with a non-default
+       action, or user semantic action that manipulated yychar.
+     - Of course, the expected token list depends on states to have
+       correct lookahead information, and it depends on the parser not
+       to perform extra reductions after fetching a lookahead from the
+       scanner and before detecting a syntax error.  Thus, state merging
+       (from LALR or IELR) and default reductions corrupt the expected
+       token list.  However, the list is correct for canonical LR with
+       one exception: it will still contain any token that will not be
+       accepted due to an error action in a later state.

+# Simple script to update the version of DTC carried by the Linux kernel
+#
+# This script assumes that the dtc and the linux git trees are in the
+# same directory. After building dtc in the dtc directory, it copies the
+# source files and generated source files into the scripts/dtc directory
+# in the kernel and creates a git commit updating them to the new
+# version.
+#
+# Usage: from the top level Linux source tree, run:
+# $ ./scripts/dtc/update-dtc-source.sh
+#
+# The script will change into the dtc tree, build and test dtc, copy the
+# relevant files into the kernel tree and create a git commit. The commit
+# message will need to be modified to reflect the version of DTC being
+# imported
+#
+# TODO:
+# This script is pretty basic, but it is seldom used so a few manual tasks
+# aren't a big deal. If anyone is interested in making it more robust, the
+# the following would be nice:
+# * Actually fail to complete if any testcase fails.
+#   - The dtc "make check" target needs to return a failure
+# * Extract the version number from the dtc repo for the commit message
+# * Build dtc in the kernel tree
