- 85xx CPU Options:
+ CONFIG_SYS_PPC64
+
+ Specifies that the core is a 64-bit PowerPC implementation (implements
+ the "64" category of the Power ISA). This is necessary for ePAPR
+ compliance, among other possible reasons.
+
CONFIG_SYS_FSL_TBCLK_DIV
Defines the core time base clock divider ratio compared to the
- Boot Delay: CONFIG_BOOTDELAY - in seconds
Delay before automatically booting the default image;
set to -1 to disable autoboot.
+ set to -2 to autoboot with no delay and not check for abort
+ (even when CONFIG_ZERO_BOOTDELAY_CHECK is defined).
See doc/README.autoboot for these options that
work with CONFIG_BOOTDELAY. None are required.

Define this to enable 32 bit addressing
- CONFIG_DRIVER_SMC91111
+ CONFIG_SMC91111
Support for SMSC's LAN91C111 chip
CONFIG_SMC91111_BASE
viewport is supported.
To enable the ULPI layer support, define CONFIG_USB_ULPI and
CONFIG_USB_ULPI_VIEWPORT in your board configuration file.
+ If your ULPI phy needs a different reference clock than the
+ standard 24 MHz then you have to define CONFIG_ULPI_REF_CLK to
+ the appropriate value in Hz.
- MMC Support:
The MMC controller on the Intel PXA is supported. To
This will also enable the command "fatwrite" enabling the
user to write files to FAT.
+CBFS (Coreboot Filesystem) support
+ CONFIG_CMD_CBFS
+
+ Define this to enable support for reading from a Coreboot
+ filesystem. Available commands are cbfsinit, cbfsinfo, cbfsls
+ and cbfsload.
+
- Keyboard Support:
CONFIG_ISA_KEYBOARD
can be displayed via the splashscreen support or the
bmp command.
+- Do compresssing for memory range:
+ CONFIG_CMD_ZIP
+
+ If this option is set, it would use zlib deflate method
+ to compress the specified memory at its best effort.
+
- Compression support:

29,916,167 26,005,792 bootm_start
30,361,327 445,160 start_kernel
+ CONFIG_CMD_BOOTSTAGE
+ Add a 'bootstage' command which supports printing a report
+ and un/stashing of bootstage data.
+
+ CONFIG_BOOTSTAGE_FDT
+ Stash the bootstage information in the FDT. A root 'bootstage'
+ node is created with each bootstage id as a child. Each child
+ has a 'name' property and either 'mark' containing the
+ mark time in microsecond, or 'accum' containing the
+ accumulated time for that bootstage id in microseconds.
+ For example:
+
+ bootstage {
+ 154 {
+ name = "board_init_f";
+ mark = <3575678>;
+ };
+ 170 {
+ name = "lcd";
+ accum = <33482>;
+ };
+ };
+
+ Code in the Linux kernel can find this in /proc/devicetree.

+ CONFIG_SPL_FRAMEWORK
+ Enable the SPL framework under common/. This framework
+ supports MMC, NAND and YMODEM loading of U-Boot and NAND
+ NAND loading of the Linux Kernel.
+
+ CONFIG_SPL_DISPLAY_PRINT
+ For ARM, enable an optional function to print more information
+ about the running system.
+
