4914af1286 image: add IH_OS_ARM_TRUSTED_FIRMWARE for ARM Trusted Firmware
To boot on ARMv8 systems with ARM Trusted Firmware, we need to
assemble an ATF-specific parameter structure and also provide the
address of the images started by ATF (e.g. BL3-3, which may be the
full U-Boot).

To allow us to identify an ARM Trusted Firmware contained in a FIT
image, this adds the necessary definitions.

089df18bfe lib: move hash CONFIG options to Kconfig
Commit 94e3c8c4fd ("crypto/fsl - Add progressive hashing support
using hardware acceleration.") created entries for CONFIG_SHA1,
CONFIG_SHA256, CONFIG_SHA_HW_ACCEL, and CONFIG_SHA_PROG_HW_ACCEL.
However, no defconfig has migrated to it.  Complete the move by first
adding additional logic to various Kconfig files to select this when
required and then use the moveconfig tool.  In many cases we can select
these because they are required to implement other drivers.  We also
correct how we include the various hashing algorithms in SPL.

This commit was generated as follows (after Kconfig additions):

[1] tools/moveconfig.py -y SHA1 SHA256 SHA_HW_ACCEL
[2] tools/moveconfig.py -y SHA_PROG_HW_ACCEL

Note:
We cannot move SHA_HW_ACCEL and SHA_PROG_HW_ACCEL simultaneously
because there is dependency between them.

c2e7e72bb9 bootm: relocate ramdisk if CONFIG_SYS_BOOT_RAMDISK_HIGH set
In 35fc84f, bootm was refactored so plain 'bootm' and
'bootm <subcommand>' shared a common implementation.
The 'bootm ramdisk' command implementation is now part of the common
implementation but not invoke by plain 'bootm' since the original
implementation never did ramdisk relocation.  Instead, ramdisk
relocation happened in image_setup_linux() which is typically called
during the OS portion of 'bootm'.

On ARM, parameters to the Linux kernel can either be passed by FDT or
ATAGS. When using FDT, image_setup_linux() is called which also triggers
ramdisk relocation.  When using ATAGS, image_setup_linux() is _not_
called because it mostly does FDT setup.

Instead of calling image_setup_linux() in both FDT and ATAGS cases,
include BOOTM_STATE_RAMDISK in the requested states during a plain
'bootm' if CONFIG_SYS_BOOT_RAMDISK_HIGH is set and remove the ramdisk
relocation from image_setup_linux().  This causes ramdisk relocation to
happen on any system where CONFIG_SYS_BOOT_RAMDISK_HIGH regardless of
the OS being booted. Also remove IMAGE_ENABLE_RAMDISK_HIGH as it was
only used by the now-removed code from image_setup_linux().

d21bd69b6e tools: mkimage: add firmware-ivt image type for HAB verification
When we want to use Secure Boot with HAB from SPL over U-Boot.img,
we need to append the IVT to the image and leave space for the CSF.
Images generated as firmware_ivt can directly be signed using the
Freescale code signing tool. For creation of a CSF, mkimage outputs
the correct HAB Blocks for the image.
The changes to the usual firmware image class are quite small,
that is why I implemented that directly into the default_image.

ff87b08107 image: fix IH_ARCH_... values for uImage compatibility
Commit 555f45d8f9 ("image: Convert the IH_... values to enums")
accidentally changed some IH_ARCH_... values.

Prior to that commit, there existed a gap between IH_ARCH_M68K and
IH_ARCH_MICROBLAZE, like follows.

  #define IH_ARCH_SPARC64         11      /* Sparc 64 Bit */
  #define IH_ARCH_M68K            12      /* M68K         */
  #define IH_ARCH_MICROBLAZE      14      /* MicroBlaze   */
  #define IH_ARCH_NIOS2           15      /* Nios-II      */

The enum conversion broke the compatibility with existing uImage
files.  Reverting 555f45d8f9 will cause build error unfortunately,
so here is a more easy fix.

I dug the git history and figured out the gap was introduced by
commit 1117cbf2ad ("nios: remove nios-32 arch").  So, I revived
IH_ARCH_NIOS just for filling the gap.

I added comments to each enum block.  Once we assign a value to
IH_... it is not allowed to change it.

6f41751f46 Revert "image.h: Tighten up content using handy CONFIG_IS_ENABLED() macro."
This reverts commit 56adbb3872.

Since commit 56adbb3872 ("image.h: Tighten up content using handy
CONFIG_IS_ENABLED() macro."), I found my boards fail to boot Linux
because the commit changed the logic of macros it touched.  Now,
IMAGE_ENABLE_RAMDISK_HIGH and IMAGE_BOOT_GET_CMDLINE are 0 for all
the boards.

As you can see in include/linux/kconfig.h, CONFIG_IS_ENABLE() (and
IS_ENABLED() as well) can only take a macro that is either defined
as 1 or undefined.  This is met for boolean options defined in
Kconfig.  On the other hand, CONFIG_SYS_BOOT_RAMDISK_HIGH and
CONFIG_SYS_BOOT_GET_CMDLINE are defined without any value in
arch/*/include/asm/config.h .  This kind of clean-up is welcome,
but the options should be moved to Kconfig beforehand.

Moreover, CONFIG_IS_ENABLED(SPL_CRC32_SUPPORT) looks weird.
It should be either CONFIG_IS_ENABLED(CRC32_SUPPORT) or
IS_ENABLED(CONFIG_SPL_CRC32_SUPPORT).  But, I see no define for
CONFIG_SPL_CRC32_SUPPORT anywhere.  Likewise for the other three.

The logic of IMAGE_OF_BOARD_SETUP and IMAGE_OF_SYSTEM_SETUP were
also changed for SPL.  This can be a problem for boards defining
CONFIG_SPL_OF_LIBFDT.  I guess it should have been changed to
IS_ENABLED(CONFIG_OF_BOARD_SETUP).

In the first place, if we replace the references in C code,
the macros IMAGE_* will go away.

  if (IS_ENABLED(CONFIG_OF_BOARD_SETUP) {
          ...
  }

f1dcee59a2 spl: Add an option to load a FIT containing U-Boot
This provides a way to load a FIT containing U-Boot and a selection of device
tree files. The board can select the correct device tree by probing the
hardware. Then U-Boot is started with the selected device tree.

4b307f2387 spl: Add a way for boards to select which device tree to load
SPL calls this function with each device tree it can find in the FIT. The
board should implement this function, using whatever hardware detection it
can muster to determine the correct device tree.

aa34fbc087 fdt: Allow libfdt to be used in SPL
Add an option to enable libfdt in SPL. This can be useful when decoding
FIT files in SPL.

We need to make sure this option is not enabled in SPL by this change.
Also this option needs to be enabled in host builds. Si add a new
IMAGE_USE_LIBFDT #define which can be used in files that are built on the
host but must also build for U-Boot and SPL.

73223f0e1b Kconfig: Move CONFIG_FIT and related options to Kconfig
There are already two FIT options in Kconfig but the CONFIG options are
still in the header files. We need to do a proper move to fix this.

Move these options to Kconfig and tidy up board configuration:

   CONFIG_FIT
   CONFIG_OF_BOARD_SETUP
   CONFIG_OF_SYSTEM_SETUP
   CONFIG_FIT_SIGNATURE
   CONFIG_FIT_BEST_MATCH
   CONFIG_FIT_VERBOSE
   CONFIG_OF_STDOUT_VIA_ALIAS
   CONFIG_RSA

Unfortunately the first one is a little complicated. We need to make sure
this option is not enabled in SPL by this change. Also this option is
enabled automatically in the host builds by defining CONFIG_FIT in the
image.h file. To solve this, add a new IMAGE_USE_FIT #define which can
be used in files that are built on the host but must also build for U-Boot
and SPL.

Note: Masahiro's moveconfig.py script is amazing.

7a80de4641 image: Correct the OS location code to work on sandbox
A recent change broke the 'bootm' command on sandbox. The root cause is
using a pointer as an address. Conversion from pointer to address needs to
use map_to_sysmem() so that sandbox can do the right thing. The problem was
pre-existing but uncovered by a recent commit.

Fix this. Also move fit_get_end() to the C file to avoid needing to include
mapmem.h (and thus asm/io.h) everywhere.

Fixes: 1fec3c5d (common/image.c: Make boot_get_ramdisk() perform a check for Android images)

66eef1e780 tools: zynqimage: Add Xilinx Zynq boot header generation to mkimage
As with other platforms vendors love to create their own boot header
formats. Xilinx is no different and for the Zynq platform/SoC there
exists the "boot.bin" which is read by the platforms bootrom. This
format is described to a useful extent within the Xilinx Zynq TRM.

This implementation adds support for the 'zynqimage' to mkimage. The
implementation only considers the most common boot header which is
un-encrypted and packed directly after the boot header itself (no
XIP, etc.). However this implementation does take into consideration the
other fields of the header for image dumping use cases (vector table and
register initialization).

027b728d4a Add support for LZ4 decompression algorithm
This patch adds support for LZ4-compressed FIT image contents. This
algorithm has a slightly worse compression ration than LZO while being
nearly twice as fast to decompress. When loading images from a fast
storage medium this usually results in a boot time win.

Sandbox-tested only since I don't have a U-Boot development system set
up right now. The code was imported unchanged from coreboot where it's
proven to work, though. I'm mostly interested in getting this recognized
by mkImage for use in a downstream project.

10b84fe1b5 rockchip: Add support for the SPI image
The Rockchip boot ROM requires a particular file format for booting from SPI.
It consists of a 512-byte header encoded with RC4, some padding and then up
to 32KB of executable code in 2KB blocks, separated by 2KB empty blocks.

Add support to mkimage so that an SPL image (u-boot-spl-dtb.bin) can be
converted to this format. This allows booting from SPI flash on supported
machines.
