expect it to be in bytes, others in MB.
Define CONFIG_MEMSIZE_IN_BYTES to make it in bytes.
+ CONFIG_OF_FLAT_TREE
+
+ New kernel versions are expecting firmware settings to be
+ passed using flat open firmware trees.
+ The environment variable "disable_of", when set, disables this
+ functionality.
+
+ CONFIG_OF_FLAT_TREE_MAX_SIZE
+
+ The maximum size of the constructed OF tree.
+
+ OF_CPU - The proper name of the cpus node.
+ OF_TBCLK - The timebase frequency.
+
- Serial Ports:
CFG_PL010_SERIAL
- Console UART Number:
CONFIG_UART1_CONSOLE
- IBM PPC4xx only.
+ AMCC PPC4xx only.
If defined internal UART1 (and not UART0) is used
as default U-Boot console.
allows for a "silent" boot where a splash screen is
loaded very quickly after power-on.
+- Gzip compressed BMP image support: CONFIG_VIDEO_BMP_GZIP
+
+ If this option is set, additionally to standard BMP
+ images, gzipped BMP images can be displayed via the
+ splashscreen support or the bmp command.
+
- Compression support:
CONFIG_BZIP2
remaining RAM in a form that can be passed as boot
argument to Linux, for instance like that:
- setenv bootargs ... mem=\$(mem)
+ setenv bootargs ... mem=\${mem}
saveenv
This way you can tell Linux not to use this memory,
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 tftpsrcp
+ is used to supply the TFTP UDP source port value.
+ If tftpsrcp isn't defined, the normal pseudo-random port
+ number generator is used.
+
+ Also, the environment variable tftpdstp is used to supply
+ the TFTP UDP destination port value. If tftpdstp isn't
+ defined, the normal port 69 is used.
+
+ The purpose for tftpsrcp 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
This option also enables the building of the cfi_flash driver
in the drivers directory
+- CFG_FLASH_QUIET_TEST
+ If this option is defined, the common CFI flash doesn't
+ print it's warning upon not recognized FLASH banks. This
+ is useful, if some of the configured banks are only
+ optionally available.
+
- CFG_RX_ETH_BUFFER:
Defines the number of ethernet receive buffers. On some
ethernet controllers it is recommended to set this value

+ tftpsrcport - If this is set, the value is used for TFTP's
+ UDP source port.
+
+ tftpdstport - If this is set, the value is used for TFTP's UDP
+ destination port instead of the Well Know Port 69.

ethernet is encapsulated/received over 802.1q
VLAN tagged frames.
- supports environment variables (through setenv / saveenv commands)

-- variable substitution using "... $(name) ..." syntax
+- variable substitution using "... ${name} ..." syntax

for example:
- setenv bootcmd bootm \$(address)

- You can also escape text by enclosing in single apostrophes, for example:
setenv addip 'setenv bootargs $bootargs ip=$ipaddr:$serverip:$gatewayip:$netmask:$hostname::off'

Implementation Internals:
CFG_INIT_RAM_ADDR should be somewhere that won't interfere
with your processor/board/system design. The default value
you will find in any recent u-boot distribution in
- Walnut405.h should work for you. I'd set it to a value larger
+ walnut.h should work for you. I'd set it to a value larger
than your SDRAM module. If you have a 64MB SDRAM module, set
it above 400_0000. Just make sure your board has no resources
that are supposed to respond to that address! That code in
establish some rules. Submissions which do not conform to these rules
may be rejected, even when they contain important and valuable stuff.
+Patches shall be sent to the u-boot-users mailing list.
When you send a patch, please include the following information with
it:
(using #ifdef), and the resulting code with the new feature
disabled must not need more memory than the old code without your
modification.
+
+* Remember that there is a size limit of 40 kB per message on the
+ u-boot-users mailing list. Compression may help.
