CONFIG_CFB_CONSOLE
Enables console device for a color framebuffer. Needs following
- defines (cf. smiLynxEM, i8042, board/eltec/bab7xx)
+ defines (cf. smiLynxEM, i8042)
VIDEO_FB_LITTLE_ENDIAN graphic memory organisation
(default big endian)
VIDEO_HW_RECTFILL graphic chip supports
'Sane' compilers will generate smaller code if
CONFIG_PRE_CON_BUF_SZ is a power of 2
+- Pre-console putc():
+ Prior to the console being initialised, console output is
+ normally silently discarded. This can be annoying if a
+ panic() happens in this time.
+
+ If the CONFIG_PRE_CONSOLE_PUTC option is defined, then
+ U-Boot will call board_pre_console_putc() for each output
+ character in this case, This function should try to output
+ the character if possible, perhaps on all available UARTs
+ (it will need to do this directly, since the console code
+ is not functional yet). Note that if the panic happens
+ early enough, then it is possible that board_init_f()
+ (or even arch_cpu_init() on ARM) has not been called yet.
+ You should init all clocks, GPIOs, etc. that are needed
+ to get the character out. Baud rates will need to default
+ to something sensible.
+
+- Safe printf() functions
+ Define CONFIG_SYS_VSNPRINTF to compile in safe versions of
+ the printf() functions. These are defined in
+ include/vsprintf.h and include snprintf(), vsnprintf() and
+ so on. Code size increase is approximately 300-500 bytes.
+ If this option is not given then these functions will
+ silently discard their buffer size argument - this means
+ you are not getting any overflow checking in this case.
+
- Boot Delay: CONFIG_BOOTDELAY - in seconds
Delay before automatically booting the default image;
set to -1 to disable autoboot.
If this defined, the driver is quiet.
The driver doen't show link status messages.
+ CONFIG_CALXEDA_XGMAC
+ Support for the Calxeda XGMAC device
+
CONFIG_DRIVER_LAN91C96
Support for SMSC's LAN91C96 chips.
Define this to use i/o functions instead of macros
(some hardware wont work with macros)
+ CONFIG_DRIVER_TI_EMAC
+ Support for davinci emac
+
+ CONFIG_SYS_DAVINCI_EMAC_PHY_COUNT
+ Define this if you have more then 3 PHYs.
+
CONFIG_FTGMAC100
Support for Faraday's FTGMAC100 Gigabit SoC Ethernet
CONFIG_SH_ETHER_CACHE_WRITEBACK
If this option is set, the driver enables cache flush.
+- TPM Support:
+ CONFIG_GENERIC_LPC_TPM
+ Support for generic parallel port TPM devices. Only one device
+ per system is supported at this time.
+
+ CONFIG_TPM_TIS_BASE_ADDRESS
+ Base address where the generic TPM device is mapped
+ to. Contemporary x86 systems usually map it at
+ 0xfed40000.
+
- USB Support:
At the moment only the UHCI host controller is
supported (PIP405, MIP405, MPC5200); define
for your device
- CONFIG_USBD_PRODUCTID 0xFFFF
+- ULPI Layer Support:
+ The ULPI (UTMI Low Pin (count) Interface) PHYs are supported via
+ the generic ULPI layer. The generic layer accesses the ULPI PHY
+ via the platform viewport, so you need both the genric layer and
+ the viewport enabled. Currently only Chipidea/ARC based
+ viewport is supported.
+ To enable the ULPI layer support, define CONFIG_USB_ULPI and
+ CONFIG_USB_ULPI_VIEWPORT in your board configuration file.
- MMC Support:
The MMC controller on the Intel PXA is supported. To
be used if available. These functions may be faster under some
conditions but may increase the binary size.
+Freescale QE/FMAN Firmware Support:
+-----------------------------------
+
+The Freescale QUICCEngine (QE) and Frame Manager (FMAN) both support the
+loading of "firmware", which is encoded in the QE firmware binary format.
+This firmware often needs to be loaded during U-Boot booting, so macros
+are used to identify the storage device (NOR flash, SPI, etc) and the address
+within that device.
+
+- CONFIG_SYS_QE_FMAN_FW_ADDR
+ The address in the storage device where the firmware is located. The
+ meaning of this address depends on which CONFIG_SYS_QE_FW_IN_xxx macro
+ is also specified.
+
+- CONFIG_SYS_QE_FMAN_FW_LENGTH
+ The maximum possible size of the firmware. The firmware binary format
+ has a field that specifies the actual size of the firmware, but it
+ might not be possible to read any part of the firmware unless some
+ local storage is allocated to hold the entire firmware first.
+
+- CONFIG_SYS_QE_FMAN_FW_IN_NOR
+ Specifies that QE/FMAN firmware is located in NOR flash, mapped as
+ normal addressable memory via the LBC. CONFIG_SYS_FMAN_FW_ADDR is the
+ virtual address in NOR flash.
+
+- CONFIG_SYS_QE_FMAN_FW_IN_NAND
+ Specifies that QE/FMAN firmware is located in NAND flash.
+ CONFIG_SYS_FMAN_FW_ADDR is the offset within NAND flash.
+
+- CONFIG_SYS_QE_FMAN_FW_IN_MMC
+ Specifies that QE/FMAN firmware is located on the primary SD/MMC
+ device. CONFIG_SYS_FMAN_FW_ADDR is the byte offset on that device.
+
+- CONFIG_SYS_QE_FMAN_FW_IN_SPIFLASH
+ Specifies that QE/FMAN firmware is located on the primary SPI
+ device. CONFIG_SYS_FMAN_FW_ADDR is the byte offset on that device.
