The IMX6 has four different speed grades determined by eFUSE SPEED_GRADING
indicated by OCOTP_CFG3[17:16] which is at 0x440 in the Fusemap Description
Table. Return this frequency so that it can be used elsewhere.
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.

Move MX5 specific set_chipselect_size function into generic i.MX part,
such that MX6 based boards are able to use this function as well.
While doing this the iomuxc gpr member needed to be consolidated between
MX5 and MX6.

This allows u-boot to load different OS or Bare Metal application on
different cores of the i.MX6 SoC.
For example: running Android on cpu0 and a RT OS like QNX/FreeRTOS on cpu1.

ENGR00287268 mx6: fix the secure boot issue on the new tapout chip
commit 424cb1a79e9f5ae4ede9350dfb5e10dc9680e90b
newer i.MX6 silicon revisions have an updated ROM and HAB API table.

Instead of duplicating the CPU definitions at mx5 and mx6 sys_proto.h header
files, introduce a common header to centralize such definitions.

This patch moves the following functions into the imx-common
directory:
- mxs_wait_mask_set()
- mxs_wait_mask_clr()
- mxs_reset_block()
These are currently used by i.MX28. But the upcoming GPMI NAND port
for i.MX6 will also use these functions. So lets move them to a
common location to re-use them.

Read memory setup registers to determine size
of available ram. This routine works for mx53/mx6x
I need this because when mx6solo called get_ram_size
with a too large maximum size, the system hanged.

Previously, the same value was returned for both mx6dl and mx6solo.
Check number of processors to differeniate.
Also, a freescale patch says that sololite has its cpu/rev
stored at 0x280 instead of 0x260.
I don't have a sololite to verify.

Init the core regulator voltage to 1.2V. This is required for the correct
functioning of the GPU and when the ARM LDO is set to 1.225V. This is a
workaround to fix some memory clock jitter.
Note: This should be but can't be done in the DCD. The bootloader
prevents access to the ANATOP registers.
