+ * Memory layout for where various images get loaded by boot scripts:
+ *
+ * I suspect address 0 is used as the SMP pen on the RPi2, so avoid this.
+ *
+ * Older versions of the boot firmware place the firmware-loaded DTB at 0x100,
+ * newer versions place it in high memory. So prevent U-Boot from doing its own
+ * DTB + initrd relocation so that we won't accidentally relocate the initrd
+ * over the firmware-loaded DTB and generally try to lay out things starting
+ * from the bottom of RAM.
+ *
+ * kernel_addr_r has different constraints on ARM and Aarch64.  For 32-bit ARM,
+ * it must be within the first 128M of RAM in order for the kernel's
+ * CONFIG_AUTO_ZRELADDR option to work. The kernel itself will be decompressed
+ * to 0x8000 but the decompressor clobbers 0x4000-0x8000 as well. The
+ * decompressor also likes to relocate itself to right past the end of the
+ * decompressed kernel, so in total the sum of the compressed and
+ * decompressed kernel needs to be reserved.
+ *
+ *   For Aarch64, the kernel image is uncompressed and must be loaded at
+ *   text_offset bytes (specified in the header of the Image) into a 2MB
+ *   boundary. The 'booti' command relocates the image if necessary. Linux uses
+ *   a default text_offset of 0x80000.  In summary, loading at 0x80000
+ *   satisfies all these constraints and reserving memory up to 0x02400000
+ *   permits fairly large (roughly 36M) kernels.
+ *
+ * scriptaddr and pxefile_addr_r can be pretty much anywhere that doesn't
+ * conflict with something else. Reserving 1M for each of them at
+ * 0x02400000-0x02500000 and 0x02500000-0x02600000 should be plenty.
+ *
+ * On ARM, both the DTB and any possible initrd must be loaded such that they
+ * fit inside the lowmem mapping in Linux. In practice, this usually means not
+ * more than ~700M away from the start of the kernel image but this number can
+ * be larger OR smaller depending on e.g. the 'vmalloc=xxxM' command line
+ * parameter given to the kernel. So reserving memory from low to high
+ * satisfies this constraint again. Reserving 1M at 0x02600000-0x02700000 for
+ * the DTB leaves rest of the free RAM to the initrd starting at 0x02700000.
+ * Even with the smallest possible CPU-GPU memory split of the CPU getting
+ * only 64M, the remaining 25M starting at 0x02700000 should allow quite
+ * large initrds before they start colliding with U-Boot.

+    contains one or more fields, with each field separated by a ",". Fields are
+    either of the form "key=value" to set a specific value, or simple "flag" to
+    set a boolean flag
+
+    The first descriptor can optionally be used to describe parameters for the
+    whole disk with the following fields:
+
+    * uuid_disk=UUID - Set the UUID for the disk
+
+    Partition descriptors can have the following fields:
+
+    * name=<NAME> - The partition name, required
+    * start=<BYTES> - The partition start offset in bytes, required
+    * size=<BYTES> - The partition size in bytes or "-" to expand it to the whole free area
+    * bootable - Set the legacy bootable flag
+    * uuid=<UUID> - The partition UUID, optional if CONFIG_RANDOM_UUID=y is enabled
+    * type=<UUID> - The partition type GUID, requires CONFIG_PARTITION_TYPE_GUID=y
+
+
+    If 'uuid' is not specified, but CONFIG_RANDOM_UUID is enabled, a random UUID
+    will be generated for the partition
+
+gpt enumerate
+~~~~~~~~~~~~~
+
+Sets the variable 'gpt_partition_list' to be a list of all the partition names
+on the device.
+
+gpt guid
+~~~~~~~~
+
+Report the GUID of a disk. If 'varname' is specified, the command will set the
+variable to the GUID, otherwise it will be printed out.
+
+gpt read
+~~~~~~~~
+
+Prints the current state of the GPT partition table. If 'varname' is specified,
+the variable will be filled with a partition string in the same format as a
+'<partition string>', suitable for passing to other 'gpt' commands.  If the
+argument is omitted, a human readable description is printed out.
+CONFIG_CMD_GPT_RENAME=y is required.
+
+gpt rename
+~~~~~~~~~~
+
+Renames all partitions named 'part' to be 'name'. CONFIG_CMD_GPT_RENAME=y is
+required.
+
+gpt repair
+~~~~~~~~~~
+
+Repairs the GPT partition tables if it they become corrupted.
+
+gpt setenv
+~~~~~~~~~~
+
+The 'gpt setenv' command will set a series of environment variables with
+information about the partition named '<partition name>'. The variables are:
+
+gpt_partition_addr
+    the starting offset of the partition in blocks as a hexadecimal number
+
+gpt_partition_size
+    the size of the partition in blocks as a hexadecimal number
+
+gpt_partition_name
+    the name of the partition
+
+gpt_partition_entry
+    the partition number in the table, e.g. 1, 2, 3, etc.
+
+gpt swap
+~~~~~~~~
+
+Changes the names of all partitions that are named 'name1' to be 'name2', and
+all partitions named 'name2' to be 'name1'. CONFIG_CMD_GPT_RENAME=y is
+required.
+
+gpt verify
+~~~~~~~~~~
+
+Sets return value $? to 0 (true) if the partition layout on the

+Booting from TPL/SPL
+====================
+
+The main U-Boot binary may be too large to be loaded directly by the Boot ROM.
+This was the original driver for splitting up U-Boot into multiple boot stages.
+
+U-Boot typically goes through the following boot phases where TPL, VPL, and SPL
+are optional. While many boards use SPL only few use TPL.
+
+TPL
+   Tertiary Program Loader. Very early init, as tiny as possible. This loads SPL
+   (or VPL if enabled).
+
+VPL
+   Verifying Program Loader. Optional verification step, which can select one of
+   several SPL binaries, if A/B verified boot is enabled. Implementation of the
+   VPL logic is work-in-progress. For now it just boots into SPL.
+
+SPL
+   Secondary Program Loader. Sets up SDRAM and loads U-Boot proper. It may also
+   load other firmware components.
+
+U-Boot
+   U-Boot proper. This is the only stage containing command. It also implements
+   logic to load an operating system, e.g. via UEFI.
+
+.. note::
+
+   The naming convention on the PowerPC architecture deviates from the other
+   archtitectures. Here the boot sequence is SPL->TPL->U-Boot.
+
+Further usages for U-Boot SPL comprise:
+
+* launching BL31 of ARM Trusted Firmware which invokes U-Boot as BL33
+* launching EDK II
+* launching Linux, e.g. :doc:`Falcon Mode <../develop/falcon>`
+* launching RISC-V OpenSBI which invokes main U-Boot
+
+Target binaries
+---------------
+
+Binaries loaded by SPL/TPL can be:
+
+* raw binaries where the entry address equals the start address. This is the
+  only binary format supported by TPL.
+* :doc:`FIT <fit/index>` images
+* legacy U-Boot images
+
+Configuration
+~~~~~~~~~~~~~
+
+Raw images are only supported in SPL if CONFIG_SPL_RAW_IMAGE_SUPPORT=y.
+
+CONFIG_SPL_FIT=y and CONFIG_SPL_LOAD_FIT=y are needed to load FIT images.
+
+CONFIG_SPL_LEGACY_IMAGE_FORMAT=y is needed to load legacy U-Boot images.
+CONFIG_SPL_LEGACY_IMAGE_CRC_CHECK=y enables checking the CRC32 of legacy U-Boot
+images.
+
+Image load methods
+------------------
+
+The image boot methods available for a board must be defined in two places:
+
+The board code implements a function board_boot_order() enumerating up to
+five boot methods and the sequence in which they are tried. (The maximum
+number of boot methods is currently hard coded as variable spl_boot_list[]).
+If there is only one boot method function, spl_boot_device() may be implemented
+instead.
+
+The configuration controls which of these boot methods are actually available.

- * Memory layout for where various images get loaded by boot scripts:
- *
- * I suspect address 0 is used as the SMP pen on the RPi2, so avoid this.
- *
- * Older versions of the boot firmware place the firmware-loaded DTB at 0x100,
- * newer versions place it in high memory. So prevent U-Boot from doing its own
- * DTB + initrd relocation so that we won't accidentally relocate the initrd
- * over the firmware-loaded DTB and generally try to lay out things starting
- * from the bottom of RAM.
- *
- * kernel_addr_r has different constraints on ARM and Aarch64.  For 32-bit ARM,
- * it must be within the first 128M of RAM in order for the kernel's
- * CONFIG_AUTO_ZRELADDR option to work. The kernel itself will be decompressed
- * to 0x8000 but the decompressor clobbers 0x4000-0x8000 as well. The
- * decompressor also likes to relocate itself to right past the end of the
- * decompressed kernel, so in total the sum of the compressed and and
- * decompressed kernel needs to be reserved.
- *
- *   For Aarch64, the kernel image is uncompressed and must be loaded at
- *   text_offset bytes (specified in the header of the Image) into a 2MB
- *   boundary. The 'booti' command relocates the image if necessary. Linux uses
- *   a default text_offset of 0x80000.  In summary, loading at 0x80000
- *   satisfies all these constraints and reserving memory up to 0x02400000
- *   permits fairly large (roughly 36M) kernels.
- *
- * scriptaddr and pxefile_addr_r can be pretty much anywhere that doesn't
- * conflict with something else. Reserving 1M for each of them at
- * 0x02400000-0x02500000 and 0x02500000-0x02600000 should be plenty.
- *
- * On ARM, both the DTB and any possible initrd must be loaded such that they
- * fit inside the lowmem mapping in Linux. In practice, this usually means not
- * more than ~700M away from the start of the kernel image but this number can
- * be larger OR smaller depending on e.g. the 'vmalloc=xxxM' command line
- * parameter given to the kernel. So reserving memory from low to high
- * satisfies this constraint again. Reserving 1M at 0x02600000-0x02700000 for
- * the DTB leaves rest of the free RAM to the initrd starting at 0x02700000.
- * Even with the smallest possible CPU-GPU memory split of the CPU getting
- * only 64M, the remaining 25M starting at 0x02700000 should allow quite
- * large initrds before they start colliding with U-Boot.
