Currently, when BR2_LINUX_KERNEL_INSTALL_TARGET=y is selected, issuing
a "saveenv" command in the U-Boot prompt may lead to rootfs corruption.
When BR2_LINUX_KERNEL_INSTALL_TARGET is not selected, then
board/freescale/common/imx/genimage.cfg.template is used as per the logic
inside board/freescale/common/imx/post-image.sh.
board/freescale/common/imx/genimage.cfg.template correctly puts the
rootfs at a safe offset.
With BR2_LINUX_KERNEL_INSTALL_TARGET=y, then
board/freescale/common/imx/genimage.cfg.template_no_boot_part or
board/freescale/common/imx/genimage.cfg.template_no_boot_part_spl
are used and no offset to the rootfs is given, which may cause U-Boot
environment area to write into the rootfs area, causing the rootfs
corruption.
Avoid this problem by placing the rootfs at an 8MB offset, just like
it is done in board/freescale/common/imx/genimage.cfg.
Tested on a imx6qp-wandboard and also on a custom imx6ull based board.
"saveenv" does not corrupt the rootfs anymore after this change.

For some SoCs (i.e.: i.MX8M Nano for now), the DDR training firmware
in the boot image depends on the type of memory installed on a board
(LPDDR4, DDR4, etc...). The previous patch makes this firmware name
agnostic of the DDR type and uses ddr_fw.bin as a generic name. This
patch makes imx8-bootloader-prepare.sh use this generic name,
independently of the kind board DDR type.

The default iamge size is 32MiB, which is quite low by today's standards.
Besides, the AArch64 kernels are relatively big, which leaves not much
room, if at all, for users to experiment on the default image.
Increase the vfat size to a more reasonable 64MiB.
Note that users who derive an in-tree defconfig for their own case will
allways hit any arbitarary size we put here, so they will anyway have to
also derive this template for their own use-cases.

In board/freescale/common/imx/imx8-bootloader-prepare.sh, when
invoking mkimage_fit_atf.sh, the U-Boot DTB is passed as parameter, to
be included in the FIT image. This parameter usually comes from
BR2_ROOTFS_POST_SCRIPT_ARGS config option. The variable
BL33=u-boot.bin set in the invocation uses the u-boot image which is
including its embedded DTB. This means the U-Boot DTB is included
twice.
The upstream script mkimage_fit_atf.sh plus its Buildroot patch are
meant to use by default the nodtb variant and use the DTB in a
separate image. See [1] and [2].
The U-Boot default DTB which will be included in u-boot.bin image is
selected with U-Boot CONFIG_DEFAULT_DEVICE_TREE, or DEVICE_TREE
variable when invoking "make". If one of those option is not aligned
to the BR2_ROOTFS_POST_SCRIPT_ARGS config option, it's possible the
two included U-Boot DTBs are different. If such case happens, the
built-in DTB is always used, regardless of the other one, selected
with BR2_ROOTFS_POST_SCRIPT_ARGS.
For example, this case happens for TechNexion Pico Pi i.MX8M and
i.MX8MMini. Since the U-Boot defconfig assumes the nodtb version will
be used, it does not set the default DTB. The u-boot.bin will include
the fsl-imx8mm-evk instead. Including the wrong board DTB breaks the
USB and UMS commands (and possibly others). Since those boards does
not have SD card slots, a recovery serial download is needed at every
update.
This patch make sure that only the separate U-Boot DTB will be
included in the FIT image by using the nodtb variant.

For boards like imx7d-pico, u-boot.img changes to u-boot-dtb.img in
U-Boot v2019.07. Therefore, we need to pick u-boot.img or u-boot-dtb.img
depending on the board configuration.
Just like was done in commit 52344e556f for the generic genimage
template, replace the U-Boot file name with UBOOTBIN, which is set
according to the BR2_TARGET_UBOOT_FORMAT_* option. We also need to set
the correct value for this variable for the u-boot.img and
u-boot-dtb.img cases.
While we're at it, rename the partition from 'u-boot-img' to 'u-boot',
to stay consistent with the generic genimage template.

Modern U-Boot assumes a layout where the first partition is an ext2 and
the kernel and dtb can be found in /boot. In other words, a layout
without boot partition.
Add a genimage.cfg template for the freescale defconfigs with such a
layout.
For now, only the layout with SPL+u-boot.img is added. It's unlikely that
the u-boot.imx approach will be used.

In order to have a better hierarchy for the genimage scripts used by
NXP mx25, mx51, mx53, mx6, mx7 SoCs, let's place them inside the
board/freescale/common/imx/ directory.
This helps in creating a more natural separation between the mxs scripts
that are placed inside the board/freescale/common/mxs/ directory.
