- 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
additional board info beside
the logo
+ When CONFIG_CFB_CONSOLE_ANSI is defined, console will support
+ a limited number of ANSI escape sequences (cursor control,
+ erase functions and limited graphics rendition control).
+
When CONFIG_CFB_CONSOLE is defined, video console is
default i/o. Serial console can be forced with
environment 'console=serial'.
- 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.

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
