Commit f4dc714aaa ("arm64: Turn u-boot.bin back into an ELF file after
relocate-rela")
introduce REMAKE_ELF option to recreate u-boot.elf from u-boot ->
u-boot.bin + DT -> u-boot.elf.
The best is to ilustrate it from make V=1 output
cat u-boot-nodtb.bin dts/dt.dtb > u-boot-dtb.bin
cp u-boot-dtb.bin u-boot.bin
aarch64-linux-gnu-objcopy -I binary -B aarch64 -O elf64-littleaarch64 u-boot.bin u-boot-elf.o
aarch64-linux-gnu-ld.bfd u-boot-elf.o -o u-boot.elf --defsym="_start"=0x8000000 -Ttext=0x8000000
Last command has no explicit linker script passed that's why toolchain
internal linker script is used.
In Binutils 2.32 case it contains SIZEOF_HEADERS symbol which has changed
behavior by commit
https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=64029e93683a266c38d19789e780f3748bd6a188
which result in situation that program headers has changed from
(xilinx_zynqmp_mini_defconfig)
Program Headers:
Type Offset VirtAddr PhysAddr
FileSiz MemSiz Flags Align
LOAD 0x0000000000010000 0x00000000fffc0000 0x00000000fffc0000

0x0000000000028918 0x0000000000028918 RW 0x10000
Xilinx tools like XSDB or Bootgen are using program headers for loading ELF
to the right location and by above binutils change ELF is loaded to
incorrect location.
The patch is explicitly use u-boot-elf.lds (just cat now) for u-boot.elf
recreation which is called when REMAKE_ELF is setup.
By purpose u-boot-elf.lds doesn't contain OUTPUT_FORMAT/OUTPUT_ARCH to be
able to use by all archs.

Normally with the SPL framework a legacy image is generated as part
|
|
of the build. This contains U-Boot along with information as to
|
|
where it should be loaded. This option instead enables generation
|
|
of a FIT (Flat Image Tree) which provides more flexibility. In
|
|
particular it can handle selecting from multiple device tree
|
|
and passing the correct one to U-Boot.

from the U-Boot FIT image like stripping off headers or modifying the

size of the blob, verification, authentication, decryption etc. in a

platform or board specific way. In order to use this feature a platform

|
or board-specific implementation of board_fit_image_post_process() must
|
|
be provided. Also, anything done during this post-processing step would
|
|
need to be comprehended in how the images were prepared before being

injected into the FIT creation (i.e. the blobs would have been pre-
|

processed before being added to the FIT image).

The old configuration infrastructure (= mkconfig + boards.cfg)

"HAS_BAR,BAZ=64", the optional options

#define CONFIG_HAS

#define CONFIG_BAZ 64

will be defined in include/config.h.

This option was prepared for the smooth migration from the old

configuration to Kconfig. Since this option will be removed sometime,
|

new boards should not use this option.
