usb: ums: add error handling for failed registration

Without this, if g_dnl_register() fails, the UMS code continues on
blindly and crashes. This fix makes it simply print an error message
instead.

ums: support block devices not MMC devices

The USB Mass Storage function could equally well support a SATA device
as support an MMC device. Update struct ums to contain a block device
descriptor, not an MMC device descriptor.

ums: remove UMS_{NUM,START}_SECTORS + UMS_START_SECTOR

These values aren't set anywhere at present, and hence have no effect.
The concept of a single global offset/number of sectors to expose through
USB Mass Storage doesn't even make sense in the face of multiple storage
devices. Remove these defines to simplify the code.

ums: remove error-checking of MMC device size

There's no reason to believe that an MMC device will incorrectly report
its capacity. Remove error checking of this value from ums_disk_init()
to simplify it.

ums: remove ums_disk_init()

Now that ums_disk_init() is so simple, there's no need for it to be a
separate function. Instead, just add it to the tail end of ums_init().

ums: move IO support code to common location

There's nothing Samsung-/board-specfic about the implementation of
ums_init(). Move the code into cmd_usb_mass_storage.c, so that it can
be shared by any user of that command.

ums: use get_device() not find_mmc_device();

get_device() is a generic routine that will support any type of block
device. Use this instead of the type-specific find_mmc_device(), for
future flexibility.

ums: move all variable declarations to the start of the block

It's easier to assign values to the variables inside an if statement body

ums: allow the user to specify the device type

Allow an optional devtype parameter to the ums command, which specifies
the type of the device to be exported. This could allow exporting a SATA
or even another USB device.

image: add support for Android's boot image format

This patch adds support for the Android boot-image format. The header
file is from the Android project and got slightly alterted so the struct +
its defines are not generic but have something like a namespace. The
header file is from bootloader/legacy/include/boot/bootimg.h. The header
parsing has been written from scratch and I looked at
bootloader/legacy/usbloader/usbloader.c for some details.
The image contains the physical address (load address) of the kernel and
ramdisk. This address is considered only for the kernel image.
The "second image" defined in the image header is currently not
supported. I haven't found anything that is creating this.

v3 (Rob Herring):
This is based on http://patchwork.ozlabs.org/patch/126797/ with the
following changes:
- Rebased to current mainline
- Moved android image handling to separate functions in
  common/image-android.c
- s/u8/char/ in header to fix string function warnings
- Use SPDX identifiers for licenses
- Cleaned-up file source information:
  android_image.h is from file include/boot/bootimg.h in repository:
  https://android.googlesource.com/platform/bootable/bootloader/legacy
  The git commit hash is 4205b865141ff2e255fe1d3bd16de18e217ef06a
  usbloader.c would be from the same commit, but it does not appear
  to have been used for any actual code.
v4:
- s/andriod/android/
- Use a separate flag ep_found to track if the entry point has been set
rather than using a magic value.

usb/gadget: add the fastboot gadget

This patch contains an implementation of the fastboot protocol on the
device side and documentation. This is based on USB download gadget
infrastructure. The fastboot function implements the getvar, reboot,
download and reboot commands. What is missing is the flash handling i.e.
writting the image to media.

v3 (Rob Herring):
This is based on http://patchwork.ozlabs.org/patch/126798/ with the
following changes:
- Rebase to current mainline and updates for current gadget API
- Use SPDX identifiers for licenses
- Traced the history and added missing copyright to cmd_fastboot.c
- Use load_addr/load_size for transfer buffer
- Allow vendor strings to be optional
- Set vendor/product ID from config defines
- Allow Ctrl-C to exit fastboot mode
v4:
- Major re-write to use the USB download gadget. Consolidated function
code to a single file.
- Moved globals into single struct.
- Use puts and putc as appropriate.
- Added CONFIG_USB_FASTBOOT_BUF_ADDR and CONFIG_USB_FASTBOOT_BUF_SIZE to
set the fastboot transfer buffer.
v5:
- Add CONFIG option documentation to README
- Rebase using new downloader registration
