# 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_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.
|
|

|
|
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.)
