- 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
CONFIG_CMD_IMLS List all found images
CONFIG_CMD_IMMAP * IMMR dump support
CONFIG_CMD_IMPORTENV * import an environment
+ CONFIG_CMD_INI * import data from an ini file into the env
CONFIG_CMD_IRQ * irqinfo
CONFIG_CMD_ITEST Integer/string test of 2 values
CONFIG_CMD_JFFS2 * JFFS2 Support
CONFIG_CMD_SPI * SPI serial bus support
CONFIG_CMD_TFTPSRV * TFTP transfer in server mode
CONFIG_CMD_TFTPPUT * TFTP put command (upload)
- CONFIG_CMD_TIME * run command and report execution time
+ CONFIG_CMD_TIME * run command and report execution time (ARM specific)
+ CONFIG_CMD_TIMER * access to the system tick timer
CONFIG_CMD_USB * USB support
CONFIG_CMD_CDP * Cisco Discover Protocol support
CONFIG_CMD_MFSL * Microblaze FSL support
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

+ 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.
