line. This happens normally in certain configurations.

* drivers/usbhost: Sheref Younan reported an error in the error handling when

connection to a USB device fails. In certain fail cases, the logic would try

to free the device class instance twice, the first was okay, but the second

nxbe_colormap was change to nxbe_configure... apparently "search-and-replace"

RGMP stands for RTOS and GPOS on Multi-Processor. RGMP is a project for

running GPOS and RTOS simultaneously on multi-processor platforms. You can

port your favorite RTOS to RGMP together with an unmodified Linux to form a

hybrid operating system. This makes your application able to use both RTOS

# CONFIG_DEBUG - enables built-in debug options

# CONFIG_DEBUG_VERBOSE - enables verbose debug output

# CONFIG_DEBUG_SYMBOLS - build without optimization and with

# CONFIG_MM_REGIONS - If the architecture includes multiple

# number of memory regions that the memory manager must

# handle and enables the API mm_addregion(start, end);
|

# CONFIG_ARCH_LOWPUTC - architecture supports low-level, boot

# CONFIG_MSEC_PER_TICK - The default system timer is 100Hz

# inheritance on mutexes and semaphores.
|

# CONFIG_SEM_PREALLOCHOLDERS: This setting is only used if priority

# to zero if no more than one thread is expected to wait for

# CONFIG_DEBUG_VERBOSE - enables verbose debug output
|

# CONFIG_DEBUG_SYMBOLS - build without optimization and with

# debug symbols (needed for use with a debugger).
|

# CONFIG_MM_REGIONS - If the architecture includes multiple

# number of memory regions that the memory manager must

# handle and enables the API mm_addregion(start, end);
|

# CONFIG_ARCH_LOWPUTC - architecture supports low-level, boot

# semaphore.
