Some MIPS boards can be configured for either little or big endian
byte order. These modes require different U-Boot images. In general there
is one preferred byteorder for a particular system but some systems are
just as commonly used in the one or the other endianness.

menu "General setup"
config ROM_EXCEPTION_VECTORS
bool "Build U-Boot image with exception vectors"
help
Enable this to include exception vectors in the U-Boot image. This is
required if the U-Boot entry point is equal to the address of the
CPU reset exception vector (e.g. U-Boot as ROM loader in Qemu,
U-Boot booted from parallel NOR flash).
Disable this, if the U-Boot image is booted from DRAM (e.g. by SPL).
In that case the image size will be reduced by 0x500 bytes.
config MIPS_CM_BASE
hex "MIPS CM GCR Base Address"
depends on MIPS_CM
default 0x16100000 if TARGET_BOSTON
default 0x1fbf8000
help
The physical base address at which to map the MIPS Coherence Manager
Global Configuration Registers (GCRs). This should be set such that
the GCRs occupy a region of the physical address space which is
otherwise unused, or at minimum that software doesn't need to access.
config MIPS_CACHE_INDEX_BASE
hex "Index base address for cache initialisation"
default 0x80000000 if CPU_MIPS32
default 0xffffffff80000000 if CPU_MIPS64
help
This is the base address for a memory block, which is used for
initialising the cache lines. This is also the base address of a memory
block which is used for loading and filling cache lines when
SYS_MIPS_CACHE_INIT_RAM_LOAD is selected.
Normally this is CKSEG0. If the MIPS system needs to move this block
to some SRAM or ScratchPad RAM, adapt this option accordingly.
config MIPS_MACH_EARLY_INIT
bool "Enable mach specific very early init code"
help
Use this to enable the call to mips_mach_early_init() very early
from start.S. This function can be used e.g. to do some very early
CPU / SoC intitialization or image copying. Its called very early
and at this stage the PC might not match the linking address
(CONFIG_TEXT_BASE) - no absolute jump done until this call.
config MIPS_CACHE_SETUP
bool "Allow generic start code to initialize and setup caches"
default n if SKIP_LOWLEVEL_INIT
default y
help
This allows the generic start code to invoke the generic initialization
of the CPU caches. Disabling this can be useful for RAM boot scenarios
(EJTAG, SPL payload) or for machines which don't need cache initialization
or which want to provide their own cache implementation.
If unsure, say yes.
config MIPS_CACHE_DISABLE
bool "Allow generic start code to initially disable caches"
default n if SKIP_LOWLEVEL_INIT
default y
help
This allows the generic start code to initially disable the CPU caches
and run uncached until the caches are initialized and enabled. Disabling
this can be useful on machines which don't need cache initialization or
which want to provide their own cache implementation.
If unsure, say yes.
config MIPS_RELOCATION_TABLE_SIZE
hex "Relocation table size"
range 0x100 0x10000
default "0x8000"
---help---
A table of relocation data will be appended to the U-Boot binary
and parsed in relocate_code() to fix up all offsets in the relocated
U-Boot.
This option allows the amount of space reserved for the table to be
adjusted in a range from 256 up to 64k. The default is 32k and should
be ok in most cases. Reduce this value to shrink the size of U-Boot
binary.
The build will fail and a valid size suggested if this is too small.
If unsure, leave at the default value.
config RESTORE_EXCEPTION_VECTOR_BASE
bool "Restore exception vector base before booting linux kernel"
help
In U-Boot the exception vector base will be moved to top of memory,
to be used to display register dump when exception occurs.
But some old linux kernel does not honor the base set in CP0_EBASE.
A modified exception vector base will cause kernel crash.
This option will restore the exception vector base to its previous
value.
If unsure, say N.
config OVERRIDE_EXCEPTION_VECTOR_BASE
bool "Override the exception vector base to be restored"
depends on RESTORE_EXCEPTION_VECTOR_BASE
help
Enable this option if you want to use a different exception vector
base rather than the previously saved one.
config NEW_EXCEPTION_VECTOR_BASE
hex "New exception vector base"
depends on OVERRIDE_EXCEPTION_VECTOR_BASE
range 0x80000000 0xbffff000
default 0x80000000
help
The exception vector base to be restored before booting linux kernel
config INIT_STACK_WITHOUT_MALLOC_F
bool "Do not reserve malloc space on initial stack"
help
Enable this option if you don't want to reserve malloc space on
initial stack. This is useful if the initial stack can't hold large
malloc space. Platform should set the malloc_base later when DRAM is
ready to use.
config SPL_INIT_STACK_WITHOUT_MALLOC_F
bool "Do not reserve malloc space on initial stack in SPL"
help
Enable this option if you don't want to reserve malloc space on
initial stack. This is useful if the initial stack can't hold large
malloc space. Platform should set the malloc_base later when DRAM is
ready to use.

config MIPS_BOOT_CMDLINE_LEGACY
bool "Hand over legacy command line to Linux kernel"
default y
help
Enable this option if you want U-Boot to hand over the Yamon-style
command line to the kernel. All bootargs will be prepared as argc/argv
compatible list. The argument count (argc) is stored in register $a0.
The address of the argument list (argv) is stored in register $a1.
config MIPS_BOOT_ENV_LEGACY
bool "Hand over legacy environment to Linux kernel"
default y
help
Enable this option if you want U-Boot to hand over the Yamon-style
environment to the kernel. Information like memory size, initrd
address and size will be prepared as zero-terminated key/value list.
The address of the environment is stored in register $a2.
config MIPS_BOOT_FDT
bool "Hand over a flattened device tree to Linux kernel"
help
Enable this option if you want U-Boot to hand over a flattened
device tree to the kernel. According to UHI register $a0 will be set

Select this if the initial stack frame could be setup in SRAM.
Normally the initial stack frame is set up in DRAM which is often
only available after lowlevel_init. With this option the initial
stack frame and the early C environment is set up before
lowlevel_init. Thus lowlevel_init does not need to be implemented
in assembler.

Select this (or let it be auto-selected by not defining any cache
sizes) in order to allow U-Boot to automatically detect the sizes
