U-Boot can be booted from NAND without SPL by prepending the DCD header to
the actual U-Boot binary. However this requires prepending 1024 bytes to
u-boot.imx (DCD + u-boot.bin).
There is already a similar target to build spl/u-boot-nand-spl.imx, add the
same option for no-SPL boot.
Tested on i.MX6ULL.
The resulting layout of u-boot-nand.imx is:
- Offset 0x0000 (0 KiB): padding
- Offset 0x0400 (1 KiB): DCD header
- Offset 0x1000 (4 KiB): u-boot.bin

The ROM API is thoroughly undocumented, but apparently passing the xor
of the real arguments as an extra argument is required [1]. Also, we
need to do the "save gd/restore gd" dance. These are both error-prone,
and lead to a lot of code duplication.
Since both imx8m[np] and imx8ulp SOCs have this, add a separate
translation unit which is included precisely when the new
CONFIG_IMX8_ROMAPI symbol is set, which provide convenience wrappers
that take care of computing the xor value as well as doing the gd
dance, and that thus have a more intuitive API. Subsequent patches
will make use of these to reduce boilerplate.
[1] One wonders, for example, if the check is only applied to the
lower 32 bits, or if we're implicitly relying on all 64-bit pointer
values we're passing effectively have 0 in the upper 32 bits.

The private key is unique and generated once per device.
And it is stored in secure memory and only accessible by CAAM.
Therefore, the public key generation and signature functions

The u-boot-with-spl.imx is a concatenation of SPL and u-boot.uim.
The u-boot.uim is u-boot.bin wrapped in uImage. In case OF_SEPARATE
is enabled, the u-boot.bin does not contain control DT for U-Boot,
and so u-boot.uim does not contain the DT, and so u-boot-with-spl.imx
does not contain the DT, and a system where u-boot-with-spl.imx is
written to offset 1024B to the start of storage no longer boots, as
it is missing DT.
In case OF_SEPARATE is enabled, u-boot.img contains both u-boot.bin
and the necessary DTs. Therefore, use u-boot.img instead of u-boot.uim
to generate u-boot-with-spl.imx when OF_SEPARATE is enabled.

Place imx_ddr_size() into a separate file.

is not built for i.MX7ULP.
Changing the logic to allow building cpu.c for i.MX7UP would

Writing/updating boot image in nand device is not
straight forward in i.MX6 platform and it requires
boot control block(BCB) to be configured.
It becomes difficult to use uboot 'nand' command to
write BCB since it requires platform specific attributes
need to be taken care of.
It is even difficult to use existing msx-nand.c driver by
incorporating BCB attributes like mxs_dma_desc does
because it requires change in mtd and nand command.
So, cmd_nandbcb implemented in arch/arm/mach-imx
BCB contains two data structures, Firmware Configuration Block(FCB)
and Discovered Bad Block Table(DBBT). FCB has nand timings,
DBBT search area, page address of firmware.
On summary, nandbcb update will
- erase the entire partition
- create BCB by creating 2 FCB/DBBT block followed by
1 FW block based on partition size and erasesize.
- fill FCB/DBBT structures
- write FW/SPL on FW1
- write FCB/DBBT in first 2 blocks
for nand boot, up on reset bootrom look for FCB structure in
first block's if FCB found the nand timings are loaded for
further reads. once FCB read done, DTTB will load and finally
firmware will be loaded which is boot image.
Refer section "NAND Boot" from doc/imx/common/imx6.txt for more usage
information.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

Each imx image is created by a separate sub-make and during this process
the mkimage config file is run though cpp.
The cpp output is to the same file no matter what imx image is being
created.
This means if two imx images are generated in parallel they will attempt
to independently produce the same pre-processed mkimage config file at
the same time.
Avoid the problem by making the pre-processed config file name unique
based on the imx image it will be used in. This way each image will
create a unique config file and they won't clobber each other when run
in parallel.
This should fixed the build bug referenced in b5b0e4e3 ("imximage:
