+ Support for Intel 8254x/8257x gigabit chips.
+
+ CONFIG_E1000_SPI
+ Utility code for direct access to the SPI bus on Intel 8257x.

+ example with the "sspi" command.
+
+ CONFIG_CMD_E1000
+ Management command for E1000 devices. When used on devices
+ with SPI support you can reprogram the EEPROM from U-Boot.
CONFIG_E1000_FALLBACK_MAC
default MAC for empty EEPROM after production.
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
Define a default value for the IP address to use for
the default Ethernet interface, in case this is not
determined through e.g. bootp.
+ (Environment variable "ipaddr")
- Server IP address:
CONFIG_SERVERIP
Defines a default value for the IP address of a TFTP
server to contact when using the "tftboot" command.
+ (Environment variable "serverip")
CONFIG_KEEP_SERVERADDR
Keeps the server's MAC address, in the env 'serveraddr'
for passing to bootargs (like Linux's netconsole option)
+- Gateway IP address:
+ CONFIG_GATEWAYIP
+
+ Defines a default value for the IP address of the
+ default router where packets to other networks are
+ sent to.
+ (Environment variable "gatewayip")
+
+- Subnet mask:
+ CONFIG_NETMASK
+
+ Defines a default value for the subnet mask (or
+ routing prefix) which is used to determine if an IP
+ address belongs to the local subnet or needs to be
+ forwarded through a router.
+ (Environment variable "netmask")
+
- Multicast TFTP Mode:
CONFIG_MCAST_TFTP
CONFIG_MXC_SPI
Enables the driver for the SPI controllers on i.MX and MXC
- SoCs. Currently only i.MX31 is supported.
+ SoCs. Currently i.MX31/35/51 are supported.
- FPGA Support: CONFIG_FPGA

+Board initialization settings:
+------------------------------
+
+During Initialization u-boot calls a number of board specific functions
+to allow the preparation of board specific prerequisites, e.g. pin setup
+before drivers are initialized. To enable these callbacks the
+following configuration macros have to be defined. Currently this is
+architecture specific, so please check arch/your_architecture/lib/board.c
+typically in board_init_f() and board_init_r().
+
+- CONFIG_BOARD_EARLY_INIT_F: Call board_early_init_f()
+- CONFIG_BOARD_EARLY_INIT_R: Call board_early_init_r()
+- CONFIG_BOARD_LATE_INIT: Call board_late_init()
+- CONFIG_BOARD_POSTCLK_INIT: Call board_postclk_init()
Configuration Settings:
-----------------------
that is executed before the actual U-Boot. E.g. when
compiling a NAND SPL.
+- CONFIG_SYS_NAND_HW_ECC_OOBFIRST
+ define this, if you want to read first the oob data
+ and then the data. This is used for example on
+ davinci plattforms.
+
- CONFIG_USE_ARCH_MEMCPY
CONFIG_USE_ARCH_MEMSET
If these options are used a optimized version of memcpy/memset will
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.
