9bac0bb374 tools: add variable padding of data image in mkimage
Use previously unused return value of function vrec_header
to return a padding size to generic mkimage. This padding
size is used in copy_files to pad with zeros after copying
the data image.

377e367a85 tools: dynamically allocate imx_header in imximage
Change to dynamically allocate the imx_header to correctly
allocate the IVT, Boot Data and DCD at correct locations
depending on the boot media.

Also check that the Image Vector Table Offset + IVT +
Boot Data + DCD <= Initial Load Region Size.

Previously struct imx_header was always 4096 bytes and was
not dealing correctly with the Image Vector Table Offset.

Now, the memory allocation looks for e.g. SD boot like this

29ce737d6f mkimage: Build signing only if board has CONFIG_FIT_SIGNATURE
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:

lib/rsa/rsa-sign.c:26:25: fatal error: openssl/rsa.h: No such file or directory

4d0985295b image: Add support for signing of FIT configurations
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).

Add support for signing of FIT configurations using the libfdt's region
support.

399c744b22 mkimage: Add -r option to specify keys that must be verified
Normally, multiple public keys can be provided and U-Boot is not
required to use all of them for verification. This is because some
images may not be signed, or may be optionally signed.

But we still need a mechanism to determine when a key must be used.
This feature cannot be implemented in the FIT itself, since anyone
could change it to mark a key as optional. The requirement for
key verification must go in with the public keys, in a place that
is protected from modification.

Add a -r option which tells mkimage to mark all keys that it uses
for signing as 'required'.

If some keys are optional and some are required, run mkimage several
times (perhaps with different key directories if some keys are very
secret) using the -F flag to update an existing FIT.

95d77b4479 mkimage: Add -F option to modify an existing .fit file
When signing images it is sometimes necessary to sign with different keys
at different times, or make the signer entirely separate from the FIT
creation to avoid needing the private keys to be publicly available in
the system.

Add a -F option so that key signing can be a separate step, and possibly
done multiple times as different keys are avaiable.

FIT image verification requires public keys. Add a convenient option to
mkimage to write the public keys to an FDT blob when it uses then for
signing an image. This allows us to use:

   mkimage -f test.its -K dest.dtb -k keys test.fit

and have the signatures written to test.fit and the corresponding public
keys written to dest.dtb. Then dest.dtb can be used as the control FDT
for U-Boot (CONFIG_OF_CONTROL), thus providing U-Boot with access to the
public keys it needs.

19c402afa2 image: Add RSA support for image signing
RSA provides a public key encryption facility which is ideal for image
signing and verification.

Images are signed using a private key by mkimage. Then at run-time, the
images are verified using a private key.

This implementation uses openssl for the host part (mkimage). To avoid
bringing large libraries into the U-Boot binary, the RSA public key
is encoded using a simple numeric representation in the device tree.

3497d43215 pxa: palmtreo680 flash programming utility
This adds a userspace linux utility that writes the u-boot image to an mtd
partition on the docg4 nand flash.

A special utility is required to do this because u-boot is partially loaded by
an initial program loader (IPL) that is permanently programmed to the boot
region of the flash.  This IPL expects the image to be written in a unique
format. The characteristics of this format can be summarized as follows:
  - Flash blocks to be loaded must have a magic number in the oob bytes of the
    first page of the block.
  - Each page must be written redundantly in the subsequent page.
  - The integrated flash controller's "reliable mode" is used, requiring that
    alternate 2k regions (4 pages) are skipped when writing.
For these reasons, a u-boot image can not be written using nandwrite from
mtd-utils.

2434c66da0 mkimage: Add map_sysmem() and IH_ARCH_DEFAULT to simplfy building
These are not actually used in mkimage itself, but the image code (which
is common with mkimage) does use them. To avoid #ifdefs in the image code
just for mkimage, define dummy version of these here. The compiler will
eliminate the dead code anyway.

A better way to handle this might be to split out more things from common.h
so that mkimage can include them. At present any file that mkimage uses
has to be very careful what headers it includes.

2386060c16 patman: fix gitutil for decorations
The git config parameter log.decorate is quite useful when working with git.
Patman, however can not handle the decorated output when parsing the commit.
To prevent this use the '--no-decorate' switch for git-log.

669dfc2ed8 fdt: Ensure that libfdt_env.h comes from U-Boot
When building host utilities, we include libfdt.h from the host, not from
U-Boot. This in turn brings in libfdt_env.h from the host, which can mess
up the types and cause a build failure, depending on the host environment.
To fix this, force inclusion of U-Boot's libfdt_env.h so that the types
are correct.

Another way to fix this is to use -nostdinc and -idirafter to ensure that
system includes are included after U-Boot ones. Unfortunately this means
that U-Boot's errno.h gets included instead of the system one. This in
turn requires a hack to errno.h to redirect things, so all in all the
solution in this patch is probably cleaner.

2979b26323 autoconfig.mk: Make it possible to define configs from other configs
Give more flexibility to define configs that can be interpreted by make, e.g. to
define fallback values of configs like in the example below.

Before this change, the config lines:
 #define CONFIG_SPL_MAX_SIZE	2048
 #define CONFIG_SPL_PAD_TO	CONFIG_SPL_MAX_SIZE
would have been changed in autoconfig.mk into:
 CONFIG_SPL_MAX_SIZE=2048
 CONFIG_SPL_PAD_TO="CONFIG_SPL_MAX_SIZE"

Hence, a make recipe using as an argument to $(OBJCOPY):
 --pad-to=$(CONFIG_SPL_PAD_TO)
would have issued:
 --pad-to="CONFIG_SPL_MAX_SIZE"
which means nothing for $(OBJCOPY) and makes it fail.

Thanks to this change, the config lines above are changed in autoconfig.mk into:
 CONFIG_SPL_MAX_SIZE=2048
 CONFIG_SPL_PAD_TO=$(CONFIG_SPL_MAX_SIZE)

Hence, the make recipe above now issues:
 --pad-to=2048
as expected from the defined config.

2b74433f36 env: Add support for UBI environment
UBI is a better place for the environment on NAND devices because it
handles wear-leveling and bad blocks.

Gluebi is needed in Linux to access the env as an MTD partition.

645b271a60 patman: Add Series-process-log tag to sort/uniq change logs
For some series with lots of changes it is annoying that duplicate change
log items are not caught. It is also helpful sometimes to sort the change
logs.

Add a Series-process-log tag to enable this, which can be placed in a
commit to control this.

The change to the Cc: line is to fix a checkpatch warning.
