i.MX53 NAND xload support

i.MX53 NAND xload support

[Sascha Hauer]

This series adds NAND xload support for i.MX53 and more specifically
to the Garz+Fricke Vincell board. With this images bigger than the
SoC internal SRAM can be supported and the Vincell can now be enabled
in the imx_v7_defconfig. The existing vincell_defconfig unfortunately
is not obsolete though, since we still need a small image for loading
it with imx-usb-loader.
Also included some misc patches I came up with during working with the
Vincell board.

[PATCH 01/12] ARM: i.MX53: do not pass base address to imx*_boot_save_loc

[Sascha Hauer]

The functions can determine the necessary base addresses themselves.

[PATCH 02/12] ARM: i.MX: Provide bootsource functions for early boot code

[Sascha Hauer]

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.

[PATCH 03/12] ARM: i.MX53: Detect booting from USB

[Sascha Hauer]

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

[PATCH 05/12] ARM: i.MX53: Implement NAND xload

[Sascha Hauer]

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.

[PATCH 07/12] ARM: i.MX53 Vincell: Reset phy consistently from device tree

[Sascha Hauer]

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.

[PATCH 08/12] ARM: i.MX53 Vincell: Adjust bbu handler partition size to real partition size

[Sascha Hauer]

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

[PATCH 11/12] ARM: imx_v7_defconfig: Enable Vincell support

[Sascha Hauer]

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