help
Force the each linker list to be aligned to this boundary. This
is required if ll_entry_get() is used, since otherwise the linker
may add padding into the table, thus breaking it.
See linker_lists.rst for full details.

config SYS_ARCH
string
help
This option should contain the architecture name to build the
appropriate arch/<CONFIG_SYS_ARCH> directory.
All the architectures should specify this option correctly.
config SYS_CPU
string
help
This option should contain the CPU name to build the correct
arch/<CONFIG_SYS_ARCH>/cpu/<CONFIG_SYS_CPU> directory.
This is optional. For those targets without the CPU directory,
leave this option empty.
config SYS_SOC
string
help
This option should contain the SoC name to build the directory
arch/<CONFIG_SYS_ARCH>/cpu/<CONFIG_SYS_CPU>/<CONFIG_SYS_SOC>.
This is optional. For those targets without the SoC directory,
leave this option empty.
config SYS_VENDOR
string
help
This option should contain the vendor name of the target board.
If it is set and
board/<CONFIG_SYS_VENDOR>/common/Makefile exists, the vendor common
directory is compiled.
If CONFIG_SYS_BOARD is also set, the sources under
board/<CONFIG_SYS_VENDOR>/<CONFIG_SYS_BOARD> directory are compiled.
This is optional. For those targets without the vendor directory,
leave this option empty.
config SYS_BOARD
string
help
This option should contain the name of the target board.
If it is set, either board/<CONFIG_SYS_VENDOR>/<CONFIG_SYS_BOARD>
or board/<CONFIG_SYS_BOARD> directory is compiled depending on
whether CONFIG_SYS_VENDOR is set or not.
This is optional. For those targets without the board directory,
leave this option empty.
config SYS_CONFIG_NAME
string
help
This option should contain the base name of board header file.
The header file include/configs/<CONFIG_SYS_CONFIG_NAME>.h
should be included from include/config.h.
config SYS_DISABLE_DCACHE_OPS
bool
help
This option disables dcache flush and dcache invalidation
operations. For example, on coherent systems where cache
operatios are not required, enable this option to avoid them.
Note that, its up to the individual architectures to implement
this functionality.
config SKIP_LOWLEVEL_INIT
bool "Skip the calls to certain low level initialization functions"
depends on ARM || NDS32 || MIPS || RISCV
help
If enabled, then certain low level initializations (like setting up
the memory controller) are omitted and/or U-Boot does not relocate
itself into RAM.
Normally this variable MUST NOT be defined. The only exception is
when U-Boot is loaded (to RAM) by some other boot loader or by a
debugger which performs these initializations itself.
config SPL_SKIP_LOWLEVEL_INIT
bool "Skip the calls to certain low level initialization functions"
depends on SPL && (ARM || NDS32 || MIPS || RISCV)
help
If enabled, then certain low level initializations (like setting up
the memory controller) are omitted and/or U-Boot does not relocate
itself into RAM.
Normally this variable MUST NOT be defined. The only exception is
when U-Boot is loaded (to RAM) by some other boot loader or by a
debugger which performs these initializations itself.

config SKIP_LOWLEVEL_INIT_ONLY
bool "Skip the call to lowlevel_init during early boot ONLY"

This allows just the call to lowlevel_init() to be skipped. The
normal CP15 init (such as enabling the instruction cache) is still
performed.
