The functions can determine the necessary base addresses themselves.

The regular bootsource functions only work in a running barebox,
provide functions for early code. This has already been done for
i.MX6, this patch adds the same functions for the other SoCs.

The USB download mode can be detected by reading the BMOD[0|1]
bits. Add support for it.

Some i.MX53 want to setup the SDRAM from C code rather than
from DCD tables. The image size for these boards is limited
to the internal SRAM size. To overcome this limitation for
i.MX53 boards booting from NAND implement an xload mechanism
to load only the PBL to SRAM and let barebox load the rest
of the image itself after SDRAM has been initialized.

The phy reset for the Vincell board is done from device tree whereas
the Vincell-LT resets the phy from board init code. Since both boards
share the same code base the regular Vincell board ends up with a
duplicated phy reset, with the second reset being done after the
FEC has been initialized.
Fix this by removing the phy reset from the board code and adding the
phy reset to the Vincell-LT dts file.

The bootloader partition size was increased to 0xe0000, so adjust
the barebox update handler partition size accordingly.

The Vincell boards do the SDRAM setup from board init code, so the
image size is limited to the internal SRAM size. To overcome this
limitation use the NAND xload support.

Now that we can start images bigger than internal SRAM size we can
enable the Vincell support in the imx_v7_defconfig.

The image built with vincell_defconfig has become too big to fit
into the SoC internal SRAM. Make it smaller by disabling UBIFS
support.
