# Format of this file: description<nl>variable<nl> helptext<nl>...<nl><nl>.
# If the question being documented is of type "choice", we list
# only the first occurring config variable. The help texts
# must not contain empty lines. No variable should occur twice; if it
# does, only the first occurrence will be used by Configure. The lines
# in a help text should be indented two positions. Lines starting with
# `#' are ignored. To be nice to menuconfig, limit your lines to 70
# characters. Use emacs' kfill.el to edit this file or you lose.

CONFIG_RTL8389
RTL8389 Environment
CONFIG_MIPS16
Building the U-Boot with MIPS16 instruction set.
CONFIG_FLASH_SRAM_ONLY
If this option is Y, U-boot does not use the DRAM chip.
The data/bss/partial program text (for example, the flash driver)
is placed in SRAM, and the static data/program text is placed in FLASH.
CONFIG_AUTO_DRAM_DETECT
If this option is Y, the DRAM size, bus width,
DRAM chip number is auto-detected.
The U-Boot must be executed from the Flash or EEPROM.
CONFIG_RTK_BOOT
Enable the Realtek's integrated menu.
CFG_LXBUS_MHZ
Lexra bus frequency, it is the reference clock of the ns16550 driver.
CFG_MHZ
CPU clock frequency
CONFIG_FLASH_BOOTING_BASE
Flash Bootup Address
0x9bc00000/0x9d000000: Flash data/instruction will be cached
0xbfc00000/0xbd000000: Flash data/instruction will not be cached
CONFIG_FLASH_SIZE_GT4MB
If the flash size is greater than 4 megabytes,
this option must be selected.
CFG_MAX_FLASH_SECT_64
Maximal Flash Sector Number.
CONFIG_CMD_DUMPREGS
Add dumpreg command.
Display CP0 registers command support.
CONFIG_SYS_TEXT_BASE
User may need to change the U-Boot bootup location based on the DRAM size.
Suggestions:
dram_size= 8MB, U-Boot Text Base=80700000
dram_size= 16MB, U-Boot Text Base=80F00000
dram_size= 32MB, U-Boot Text Base=81F00000
dram_size= 64MB, U-Boot Text Base=83F00000
dram_size=128MB, U-Boot Text Base=87F00000
CONFIG_CONSTRUCT_LOADER
Construct basic parameters for PHY and MAC chips. This procedure
was designed in both RTK's bootloader and SDK. Should turn on one of them.
CONFIG_CONSTRUCT_DISABLED
While choosing Chip Construct (e.g. new patch), it's allowed to
disable itself during booting. That is, no any patch procedure
will be applied.
(A command "rtk construct" can do the Chip Construct any time
in uboot.)
