| ARM boards: Use _text rather than TEXT_BASE
|
| With compressed image support TEXT_BASE will become the base
| address of the uncompressed image. What the boards want instead
| is the base address of the decompressor code or, if not compressed,
| the base address of the uncompressed image. Use _text which is
| the correct one for both cases.

This fixes it by adding the jump. Also imx_nand_load_image is directly
called from lowlevel_init.S which fixes compilation with pbl support
enabled.

Booting from SPI on an AM35xx (and possibly other TI SOCs) requires
a special format:
- 32 bit image size in big-endian
- 32 bit load address in big-endian
- binary image converted from little- to big-endian
The mk-am35xx-spi-image tool converts barebox.bin to
this format.

On some SoCs (for example AM35xx), the ROM bootloader passes useful
information in r0 when jumping to barebox.
To avoid overwriting this in the generic reset code, we introduce
common_reset as a C function and as an assembler macro. This is then
called form the reset entry point (either in common or in board code).
This patch is based on code by Sascha Hauer <s.hauer@pengutronix.de>.

OMAP3 is the only architecture which has a arch_init_lowlevel in
which it invalidates the dcache. This can easily be done in
board_init_lowlevel aswell. Since on OMAP3 we are always executed
in SRAM we'll never need a board specific lowlevel_init. So the
easiest way of getting rid of this special handling is to just
rename the function.

When the i.MX28 boots from USB, the ROM code sets this bit. When
after a reset the ROM code detects that this bit is set it will
boot from USB again. This means that if we boot once from USB the
chip will continue to boot from USB until the next power cycle.
To prevent this (and boot from the configured bootsource instead)
clear this bit here. This bit is not documented in the datasheets,
it was figured out the hard way. Whether this is the same on i.MX23
is currently not known.
