Currently the hash functions used in RSA are called directly from the sha1
and sha256 libraries. Change the RSA checksum library to use the progressive
hash API's registered with struct hash_algo. This will allow the checksum
library to use the hardware accelerated progressive hash API's once available.

The dumpimage is able to extract components contained in a FIT image:
$ ./dumpimage -T flat_dt -i CONTAINER.ITB -p INDEX FILE
The CONTAINER.ITB is a regular FIT container file. The INDEX is the poisition
of the sub-image to be retrieved, and FILE is the file (path+name) to save the
extracted sub-image.
For example, given the following kernel.its to build a kernel.itb:
/dts-v1/;
/ {
...
images {
kernel@1 {
description = "Kernel 2.6.32-34";
data = /incbin/("/boot/vmlinuz-2.6.32-34-generic");
type = "kernel";
arch = "ppc";
os = "linux";
compression = "gzip";
load = <00000000>;
entry = <00000000>;
hash@1 {
algo = "md5";
};
};
...
};
...
};
The dumpimage can extract the 'kernel@1' node through the following command:
$ ./dumpimage -T flat_dt -i kernel.itb -p 0 kernel
Extracted:
Image 0 (kernel@1)
Description: Kernel 2.6.32-34
Created: Wed Oct 22 15:50:26 2014
Type: Kernel Image
Compression: gzip compressed
Data Size: 4040128 Bytes = 3945.44 kB = 3.85 MB
Architecture: PowerPC
OS: Linux
Load Address: 0x00000000
Entry Point: 0x00000000
Hash algo: md5
Hash value: 22352ad39bdc03e2e50f9cc28c1c3652
Which results in the file 'kernel' being exactly the same as '/boot/vmlinuz-2.6.32-34-generic'.

Like many platforms, the Altera socfpga platform requires that the
preloader be "signed" in a certain way or the built-in boot ROM will
not boot the code.
This change automatically creates an appropriately signed preloader
from an SPL image.
The signed image includes a CRC which must, of course, be generated
with a CRC generator that the SoCFPGA boot ROM agrees with otherwise
the boot ROM will reject the image.
Unfortunately the CRC used in this boot ROM is not the same as the
Adler CRC in lib/crc32.c. Indeed the Adler code is not technically a
CRC but is more correctly described as a checksum.
Thus, the appropriate CRC generator is added to lib/ as crc32_alt.c.

Commit e3a5bbce broke the FIT image tests by not loading a ramdisk even if

will be loaded if a non-zero load address is provided.

The new atmelimage converts a machine code BLOB to bootable ROM image. Atmel
ROM has no sophisticated image format, it only checks the first 7 ARM vectors.
The vectors can contain valid B or LDR opcodes, the 6'th vector contains the
image size to load.
Additionally the PMECC header can be written by the atmelimage target. The
parameters must be given via the -n switch as a coma separated list. For
example:
mkimage -T atmelimage \
-n usePmecc=1,sectorPerPage=4,sectorSize=512,spareSize=64,eccBits=4,eccOffset=36 \
-d spl/u-boot-spl.bin boot.bin
A provided image can be checked for correct header setup. It prints out the
PMECC header parameters if it has one and the 6'th interrupt vector content.

This patch adds support for the Android boot-image format. The header
file is from the Android project and got slightly alterted so the struct +
its defines are not generic but have something like a namespace. The
header file is from bootloader/legacy/include/boot/bootimg.h. The header
parsing has been written from scratch and I looked at
bootloader/legacy/usbloader/usbloader.c for some details.
The image contains the physical address (load address) of the kernel and
ramdisk. This address is considered only for the kernel image.
The "second image" defined in the image header is currently not
supported. I haven't found anything that is creating this.
v3 (Rob Herring):
This is based on http://patchwork.ozlabs.org/patch/126797/ with the
following changes:
- Rebased to current mainline
- Moved android image handling to separate functions in
common/image-android.c
- s/u8/char/ in header to fix string function warnings
- Use SPDX identifiers for licenses
- Cleaned-up file source information:
android_image.h is from file include/boot/bootimg.h in repository:
https://android.googlesource.com/platform/bootable/bootloader/legacy
The git commit hash is 4205b865141ff2e255fe1d3bd16de18e217ef06a
usbloader.c would be from the same commit, but it does not appear
to have been used for any actual code.
v4:
- s/andriod/android/
- Use a separate flag ep_found to track if the entry point has been set
rather than using a magic value.

Add mkimage support for generating and verifying MXS bootstream.
The implementation here is mostly a glue code between MXSSB v0.4
and mkimage, but the long-term goal is to rectify this and merge
MXSSB with mkimage more tightly. Once this code is properly in
U-Boot, MXSSB shall be deprecated in favor of mkimage-mxsimage
support.
Note that the mxsimage generator needs libcrypto from OpenSSL, I
therefore enabled the libcrypto/libssl unconditionally.

If a specific configuraion is selected by the bootm command, e.g. with
'bootm 84000000#recoveryconf' we must honour this for not just the kernel,
but also the ramdisk and FDT.
In the conversion to using a common fit_image_load() function for loading
images from FITs (commits a51ec63 and 53f375f) this feature was lost.
Reinstate it by passing the selected configuration back from
fit_image_load() to boot_get_kernel(), then use this configuration
(which is stored in images->fit_uname_cfg) in both boot_get_ramdisk()
and boot_get_fdt().

At present mkimage is set up to always build with image signing support.
This means that the SSL libraries (e.g. libssl-dev) are always required.
Adjust things so that mkimage can be built with and without image signing,
controlled by the presence of CONFIG_FIT_SIGNATURE in the board config file.
If CONFIG_FIT_SIGNATURE is not enabled, then mkimage will report a warning
that signing is not supported. If the option is enabled, but libraries are
not available, then a build error similar to this will be shown:

While signing images is useful, it does not provide complete protection
against several types of attack. For example, it it possible to create a
FIT with the same signed images, but with the configuration changed such
that a different one is selected (mix and match attack). It is also possible
to substitute a signed image from an older FIT version into a newer FIT
(roll-back attack).

For tracing it is useful to run as much of U-Boot as possible so as to get

to have to stop tracing before bootm starts.

At present the bootm code is mostly duplicated for the plain 'bootm'
command and its sub-command variant. This makes the code harder to
maintain and means that changes must be made to several places.
Introduce do_bootm_states() which performs selected portions of the bootm
work, so that both plain 'bootm' and 'bootm <sub_command>' can use the
same code.
Additional duplication exists in bootz, so tidy that up as well. This

previously-duplicated code missed some chunks of code.

Much of the image code uses addresses as ulongs and pointers interchangeably,
casting between the two forms as needed.
This doesn't work with sandbox, which has a U-Boot RAM buffer which is
separate from the host machine's memory.
Adjust the cost so that translating from a U-Boot address to a pointer uses
map_sysmem(). This allows bootm to work correctly on sandbox.
Note that there are no exhaustive tests for this code on sandbox, so it is
possible that some dark corners remain.
