Added 38.4MHz/48MHz entries to pll_x_table for CPU PLL. Needs
to be measured - should be close to 700MHz (1.4G/2).
Note that some freqs aren't in the PLLU table in T210 TRM
(13, 26MHz), so I used the 12MHz table entry for them. They
shouldn't be selected since they're not viable T210 OSC freqs.
Since there are now 2 new OSC defines, all tables (pll_x_table,
PLLU) had to increase by two entries, but since 38.4/48MHz are
not viable osc freqs on T20/30/114, etc, they're just set to 0.

This introduces code to read the value of the SYS_BOOT pins on the OMAP3, as
well as the memory-preferred scheme for the interpretation of each value.
Signed-off-by: Paul Kocialkowski <contact@paulk.fr>
OMAP devices might boot from peripheral devices, such as UART or USB.
When that happens, the U-Boot SPL tries to boot the next stage (complete U-Boot)
from that peripheral device, but in most cases, this is not a valid boot device.
This introduces a fallback option that reads the SYS_BOOT pins, that are used by
the bootrom to determine which device to boot from. It is intended for the
SYS_BOOT value to be interpreted in the memory-preferred scheme, so that the
U-Boot SPL can load the next stage from a valid location.
Practically, this options allows loading the U-Boot SPL through USB and have it
load the next stage according to the memory device selected by SYS_BOOT instead
of stalling.

This cleans up the SPL boot devices for omap platforms and introduces support
for missing boot devices.
Signed-off-by: Paul Kocialkowski <contact@paulk.fr>
This introduces OMAP3 support for the common omap boot code, as well as a
major cleanup of the common omap boot code.
First, the omap_boot_parameters structure becomes platform-specific, since its
definition differs a bit across omap platforms. The offsets are removed as well
since it is U-Boot's coding style to use structures for mapping such kind of
data (in the sense that it is similar to registers). It is correct to assume
that romcode structure encoding is the same as U-Boot, given the description
of these structures in the TRMs.
The original address provided by the bootrom is passed to the U-Boot binary
instead of a duplicate of the structure stored in global data. This allows to
have only the relevant (boot device and mode) information stored in global data.
It is also expected that the address where the bootrom stores that information
is not overridden by the U-Boot SPL or U-Boot.
The save_omap_boot_params is expected to handle all special cases where the data
provided by the bootrom cannot be used as-is, so that spl_boot_device and
spl_boot_mode only return the data from global data.
All of this is only relevant when the U-Boot SPL is used. In cases it is not,
save_boot_params should fallback to its weak (or board-specific) definition.
save_omap_boot_params should not be called in that context either.

IODelay recalibration, there is a potential for a significant glitch
which may cause functional impairment to certain hardware. It is
hence recommended to do muxing as part of IOdelay recalibration.

- Unlock IODLAY config registers.
- Perform IO delay calibration with predefined values.

Note that the IMX6SDLRM and the IMX6SXRM do not indicate this in the
their Fusemap Description Table however Freescale has confirmed that these
eFUSE bits match the description within the IMX6DQRM and that they will
be added to the next revision of the respective reference manuals.
These have been tested with IMX6 Quad/Solo/Dual-light 800Mhz and 1GHz grades.
