imx: hab: extend hab_auth_img to calculate ivt_offset
Current implementation of hab_auth_img command needs ivt_offset to
authenticate the image. But ivt header is placed at the end of image
date after padding.
This leaves the usage of hab_auth_img command to fixed size or static
offset for ivt header. New function "get_image_ivt_offset" is introduced
to find the ivt offset during runtime. The case conditional check in this
function is same as boot_get_kernel in common/bootm.c

have IVT at the end and ivt_offset option can be left optional

SPL: Add HAB image authentication to FIT
Introduce two board level callback functions to FIT image loading process, and
a SPL_FIT_FOUND flag to differentiate FIT image or RAW image.
Implement functions in imx common SPL codes to call HAB funtion
to authenticate the FIT image. Generally, we have to sign multiple regions
in FIT image:
1. Sign FIT FDT data (configuration)
2. Sign FIT external data (Sub-images)
Because the CSF supports to sign multiple memory blocks, so that we can use one
signature to cover all regions in FIT image and only authenticate once.
The authentication should be done after the entire FIT image is loaded into
memory including all sub-images.
We use "-p" option to generate FIT image to reserve a space for FIT IVT
and FIT CSF, also this help to fix the offset of the external data (u-boot-nodtb.bin,
ATF, u-boot DTB).
The signed FIT image layout is as below:

| FIT | FIT | FIT | | U-BOOT | ATF | U-BOOT |
| FDT | IVT | CSF | | nodtb.bin | | DTB |

dra7: Allow selecting a new dtb after board detection.
The DRA7 platforms requires that the dtb used in the SPL really matches the
platform to have the best MMC performances.
To detect the board type/version an I2C EEPROM is read. This requires that
DM is initialized before the detection. As a consequence we must reset the
DM after the board detection is a new dtb would better match the platform.
drivers: core: nullify gd->dm_root after dm_uninit()
To reset the DM after a new dtb is loaded, we need to call dm_uninit()
and then dm_init(). This fails however because gd->dm_root is not nullified
by dm_uninit().
Fixing it by setting gd->dm_root in dm_uninit().
drivers: core: Add the option SPL_DM_DEVICE_REMOVE to the Kconfig
It is currently not possible to include the support to remove devices in
the SPL. This is however needed by platforms that re-select their dtb after
DM is initialized; they need to remove all the previously bound devices
before triggering a scan of the new DT.
Add a Kconfig option to be able to include the support for device removal
in the SPL.
lib: fdtdec: Add function re-setup the fdt more effeciently
In some cases it may be useful to be able to change the fdt we have been
using and use another one instead. For example, the TI platforms uses an
EEPROM to store board information and, based on the type of board,
different dtbs are used by the SPL. When DM_I2C is used, a first dtb must
be used before the I2C is initialized and only then the final dtb can be
selected.
To speed up the process and reduce memory usage, introduce a new function
fdtdec_setup_best_match() that re-use the DTBs loaded in memory by
fdtdec_setup() to select the best match.
configs: dra7xx-evm: increase the size of the malloc's pool before relocation
This is required to take advantage of MULTI_DTB_FIT before relocation.
If it is too low, DM will be initialized only after relocation has
taken place. That is too late for the DRA7 because I2C DM is used before
the relocation to setup the voltages required, among other things, to
properly initialize the DRAM.
ti: remove usage of DM_I2C_COMPAT and don't disable DM_I2C in SPL
DM_I2C_COMPAT is a compatibility layer that allows using the non-DM I2C
API when DM_I2C is used. The goal is to eventually remove DM_I2C_COMPAT
when all I2C "clients" have been migrated to use the DM API.
This a step in that direction for the TI based platforms.

Enable SPI flash support under U-Boot and SPL. The ENV size and offset,
ported from U-Boot 2013.01 Marvell version: 2015_T1.0p16
To create U-Boot image for SPI flash, user would need to replace
* CONFIG_MVEBU_SPL_BOOT_DEVICE_MMC with CONFIG_MVEBU_SPL_BOOT_DEVICE_SPI
* CONFIG_ENV_IS_IN_MMC with CONFIG_ENV_IS_IN_SPI_FLASH

arm: mvebu: helios4: Reduce U-Boot image size
Remove unused I2C support in SPL and use simple_malloc functions to
reduce SPL image size.
Since Helios4 does not have any PCIe allocated on SerDes, remove PCI
support. MTD layer on top of SPI flash is not needed, remove it also.

Store the environment before 1M into the block device.
This constant is easier to remember, saves a little space,

clearfog.
