This directory contains the source code for U-Boot, a boot loader for
-Embedded boards based on PowerPC and ARM processors, which can be
-installed in a boot ROM and used to initialize and test the hardware
-or to download and run application code.
+Embedded boards based on PowerPC, ARM, MIPS and several other
+processors, which can be installed in a boot ROM and used to
+initialize and test the hardware or to download and run application
+code.
The development of U-Boot is closely related to Linux: some parts of
the source code originate in the Linux source tree, we have some

Enables SPI driver (so far only tested with
SPI configuration items (port pins to use, etc). For
an example, see include/configs/sacsng.h.
-- FPGA Support: CONFIG_FPGA_COUNT
-
- Specify the number of FPGA devices to support.
-
- CONFIG_FPGA
-
- Used to specify the types of FPGA devices. For
- example,
- #define CONFIG_FPGA CFG_XILINX_VIRTEX2
-
- CFG_FPGA_PROG_FEEDBACK
-
- Enable printing of hash marks during FPGA
- configuration.
-
- CFG_FPGA_CHECK_BUSY

- be written.
-
- CONFIG_FPGA_DELAY
-
- If defined, a function that provides delays in the
- FPGA configuration driver.
-
- CFG_FPGA_CHECK_CTRLC
-

- loading. For example, abort during Virtex II
- configuration if the INIT_B line goes low (which
- indicated a CRC error).
-
- CFG_FPGA_WAIT_INIT
-

+
CFG_HUSH_PARSER
Define this variable to enable the "hush" shell (from
When SystemACE support is added, the "ace" device type
becomes available to the fat commands, i.e. fatls.
+- TFTP Fixed UDP Port:
+ CONFIG_TFTP_PORT
+
+ If this is defined, the environment variable tftpport
+ is used to supply the TFTP UDP source port value.
+ If tftpport isn't defined, the normal pseudo-random port
+ number generator is used.
+
+ The purpose for this is to allow a TFTP server to
+ blindly start the TFTP transfer using the pre-configured
+ target IP address and UDP port. This has the effect of
+ "punching through" the (Windows XP) firewall, allowing
+ the remainder of the TFTP transfer to proceed normally.
+ A better solution is to properly configure the firewall,
+ but sometimes that is not allowed.
+
- Show boot progress:
CONFIG_SHOW_BOOT_PROGRESS
14 common/cmd_bootm.c No initial ramdisk, no multifile, continue.
15 common/cmd_bootm.c All preparation done, transferring control to OS

The length in bytes of the EEPROM memory array address. Note
that this is NOT the chip address length!
+ - CFG_I2C_EEPROM_ADDR_OVERFLOW:
+ EEPROM chips that implement "address overflow" are ones
+ like Catalyst 24WC04/08/16 which has 9/10/11 bits of
+ address and the extra bits end up in the "chip address" bit
+ slots. This makes a 24WC08 (1Kbyte) chip look like four 256
+ byte chips.
+
+ Note that we consider the length of the address field to
+ still be one byte because the extra address bits are hidden
+ in the chip address.
+
- CFG_EEPROM_SIZE:
The size in bytes of the EEPROM device.
environment area within the total memory of your DataFlash placed
at the specified address.
+- CFG_ENV_IS_IN_NAND:
+
+ Define this if you have a NAND device which you want to use
+ for the environment.
+
+ - CFG_ENV_OFFSET:
+ - CFG_ENV_SIZE:
+
+ These two #defines specify the offset and size of the environment
+ area within the first NAND device.

+ doing! (11-4) [MPC8xx/82xx systems only]
- CFG_INIT_RAM_ADDR:
CFG_POCMR2_MASK_ATTRIB: (MPC826x only)
Overrides the default PCI memory map in cpu/mpc8260/pci.c if set.
+- CONFIG_ETHER_ON_FEC[12]
+ Define to enable FEC[12] on a 8xx series processor.
+
+- CONFIG_FEC[12]_PHY
+ Define to the hardcoded PHY address which corresponds
+ to the given FEC; i. e.
+ #define CONFIG_FEC1_PHY 4
+ means that the PHY with address 4 is connected to FEC1
+
+ When set to -1, means to probe for first available.
+
+- CONFIG_FEC[12]_PHY_NORXERR
+ The PHY does not have a RXERR line (RMII only).
+ (so program the FEC to ignore it).

+ Note that this is a global option, we can't
+ have one FEC in standard MII mode and another in RMII mode.
+
+- CONFIG_CRC32_VERIFY

+ The syntax is:
+
+ => crc32 -v <address> <count> <crc32>
+
+ Where address/count indicate a memory area
+ and crc32 is the correct crc32 which the
+ area should have.
+
+- CONFIG_LOOPW
+ Add the "loopw" memory command. This only takes effect if
+ the memory commands are activated globally (CFG_CMD_MEM).
+
+- CONFIG_MX_CYCLIC
+ Add the "mdc" and "mwc" memory commands. These are cyclic
+ "md/mw" commands.
+ Examples:
+
+ => mdc.b 10 4 500
+ This command will print 4 bytes (10,11,12,13) each 500 ms.
+
+ => mwc.l 100 12345678 10
+ This command will write 12345678 to address 100 all 10 ms.
+
+ This only takes effect if the memory commands are activated
+ globally (CFG_CMD_MEM).
+
+- CONFIG_SKIP_LOWLEVEL_INIT
+- CONFIG_SKIP_RELOCATE_UBOOT
+
+ [ARM only] If these variables are defined, then
+ certain low level initializations (like setting up
+ the memory controller) are omitted and/or U-Boot does
+ not relocate itself into RAM.
+ Normally these variables MUST NOT be defined. The
+ only exception is when U-Boot is loaded (to RAM) by
+ some other boot loader or by a debugger which
+ performs these intializations itself.
