a768386746 mx6: Read silicon revision from register
Instead of hardcoding the mx6 silicon revision, read it in run-time.

Also, besides the silicon version print the mx6 variant type: quad,dual/solo
or solo-lite.

Tested on a mx6qsabrelite, where it shows:

CPU:   Freescale i.MX6Q rev1.0 at 792 MHz

cece262209 mx6: Fix reset cause for Power On Reset case
After booting mx6qsabrelite from POR the following is reported:

CPU:   Freescale i.MX61 family rev1.0 at 792 MHz
Reset cause: unknown reset

This is because both the POR and WDOG bits are set after reset.

Fix this by also checking both bits in the POR case.

1c9ceff8ca i.MX6: mx6q_sabrelite: add CONFIG_REVISION_TAG
This is needed to support Freescale-supplied userspaces.

At the moment, both the IPU and VPU libraries provided by Freescale
in the "imx-lib" package contain routines which scrape the system
revision from /proc/cpuinfo. In the VPU library, this information is
used to load the proper firmware, allowing a single binary to be used
across various i.MX processors.

49d3e27211 imximage: Remove overwriting of flash_offset
The flash header supports different flash offsets for different
boot devices. E.g. parallel NOR or OneNAND use a different offset
than FLASH_OFFSET_STANDARD (== 0x400).

The flash offset is correctly read from the configuration in
parse_cfg_cmd(). But is then overwritten wrongly in set_imx_hdr_v1/2().

Fix this by removing this overwriting. Use the flash offset
correctly read from the configuration, instead.

If there is no flash_offset read from the configuration file, i.e.
the BOOT_FROM tag is missing, exit with an error message.

toolchain's one, this works around the use of libraries from GCC, which might be
little endian.
