This patch implements USB Mass Storage device Class, which allows the Zephyr target Board to appear as a USB drive to a host. This code would invoke disk_read() /disk_write() hooks which are to be provided by the storage layer. The Mass Storage protocol state machine is based on mbed's implementation. We augment it by adding Zephyr's USB transport and Storage APIs, and offload disk ops to a fiber context rather than in the USB irq context. origin: https://developer.mbed.org/users/mbed_official/code/USBDevice/file/01321bd6ff89/USBMSD Jira: ZEP-233 Change-Id: I8199598c76da20ab20012d81dac7615f6a366303 Signed-off-by: Jithu Joseph <jithu.joseph@intel.com>
