ret = __do_bootm_linux and fall through?

No,
__do_bootm_linux does not return if everything works ok.
From the barebox point of view there is no difference in closing or
not the files.
The difference is when the files are from a server.

Vicente.

Yes,
for example when transferring a 51MB initramfs from PC to tablet
through omap4_usbboot_fs it goes from 6MBps to 15MBps, from 8 seconds
to 3.3.

Vicente.

+-------------- omap4_usb_booting --------------
+
+omap4 processors have support for booting from the usb port. To be able to fully
+use this feature you will need to enable the following:
+ OMAP4_USBBOOT
+ This CONFIG_ option adds the required infrastructure.
+ DRIVER_SERIAL_OMAP4_USBBOOT
+ This adds console support over the same usb port used for booting.
+ FS_OMAP4_USBBOOT
+ This adds filesystem support over the same usb port used for booting.
+
+To send the bootloader to the processor, execute the utility omap4_usbboot which
+can be found in the scripts subdirectory.
+omap4_usbboot takes two parameters:
+ the bootloader image
+ a directory name which will be the root for the guest system
+Once omap4_usbboot is running it will wait for enumeration of the omap4 cpu on
+the host usb subsystem. Then power on or reset the cpu with the correct sys_boot
+or SAR memory configuration.
+
+If everything works, barebox's first stage will boot and afterwards it will load
+the second stage found at "/barebox.bin".
+Barebox's second stage will still have access to the usb filesystem, so an
+initrd and a zImage can be loaded.
+
+Overall this procedure frees the developer of continously be changing the SD
+card or other boot media from host to target.
