Error in enabling usb support in u-boot

Question

I have Am-1808, and i need to boot from usb instead of sd-card as explained here. Previously i was using Davinci-PSP-SDK-03.21.00.4, but the uboot of this psp don't have usb support (i confirmed this by typing 'help' in the uboot menu and it didn't have 'usb' command available). So i downloaded u-boot from denx tree which had 'usb 'command in the u-boot menu and then i added the usb configurations in the da850evm.h as suggested by Ti employee. Here's the configuration:

/*
 * USB configuration
 */
#define CONFIG_USB_DA8XX        /* Platform hookup to MUSB controller */
#define CONFIG_MUSB_UDC

#ifdef CONFIG_USB_DA8XX

#ifdef CONFIG_MUSB_HCD          /* include support for usb host */
#define CONFIG_CMD_USB          /* include support for usb cmd */

#define CONFIG_USB_STORAGE      /* MSC class support */
#define CONFIG_CMD_STORAGE      /* inclue support for usb-storage cmd */
#define CONFIG_CMD_FAT          /* inclue support for FAT/storage */
#define CONFIG_DOS_PARTITION    /* inclue support for FAT/storage */

#ifdef CONFIG_USB_KEYBOARD      /* HID class support */
#define CONFIG_SYS_USB_EVENT_POLL
#define CONFIG_PREBOOT "usb start"
#endif /* CONFIG_USB_KEYBOARD */

#endif /* CONFIG_MUSB_HCD */

#ifdef CONFIG_MUSB_UDC
/* USB device configuration */
#define CONFIG_USB_DEVICE               1
#define CONFIG_USB_TTY                  1
#define CONFIG_SYS_CONSOLE_IS_IN_ENV    1
/* Change these to suit your needs */
#define CONFIG_USBD_VENDORID            0x0451
#define CONFIG_USBD_PRODUCTID           0x5678
#define CONFIG_USBD_MANUFACTURER        "Texas Instruments"
#define CONFIG_USBD_PRODUCT_NAME        "DA830EVM"
#endif /* CONFIG_MUSB_UDC */

#endif /* CONFIG_USB_DA8XX */

And on compiling i get these errors:

usbtty.c:126: error: 'EP0_MAX_PACKET_SIZE' undeclared here (not in a function)
usbtty.c:219: error: 'UDC_INT_ENDPOINT' undeclared here (not in a function)

make[1]: Leaving directory `/home/user/Desktop/Uboot_Screwed/u-boot-    omapl1/drivers/serial'
make: *** [drivers/serial/libserial.a] Error 2

If u can please tell how can i get rid of these errors, [I have googled it but didn't find anything useful] or if u can please give me a link of u-boot for Am-1808 which has 'usb' command supported in the u-boot menu.

Update:

I defined CONFIG_USB_TTY in the da850evm.h as auselen pointed, now i am able to resolve previous errors, but i am getting new errors, here's the output of the terminal:

Any idea how can i fix them ?

It looks like you need to define/enable CONFIG_USB_TTY.
