Introduce a new configuration "CONFIG_MXC_GPT_HCLK". When it is set,
the GPT will use 24Mhz OSC as clock source. Otherwise, the GPT will
use 32Khz OSC as clock source.
Since only the GPT on iMX6 series provide the clock source option for
24Mhz OSC. For other series(MX5), if the configuration is set, the
perclk will be selected as clock source.
MX6Q/D Rev 1.0 and MX6SL can't use the 24Mhz OSC clock source option,
so select the perclk for them. For MX6SL, we will set the OSC 24Mhz to
perclk in CCM, so eventually the clock comes from OSC 24Mhz.

The self-bias circuit is used by the bandgap during startup.
Once the bandgap has stabilized, the self-bias circuit should be
disabled for best noise performance of analog blocks.
Also this bit should be disabled before the chip enters STOP mode or
when ever the regular bandgap is disabled.

THe anatop registers structure is duplicated with CCM structure at
PLL fields.
Since we are suggested not to use the name "anatop" any longer, merge
the anatop registers to the CCM structure "mxc_ccm_reg" and use CCM
to replace anatop.

This problem is found when debugging QuadSPI. When "A" bit is enabled,
unaligned access will cause data abort exception. Actually, we do not
want this exception. So clear the align bit for MX6 SOCs.

To fsl_qspi_write_data and fsl_qspi_ip_read, pointer txbuf and
rxbuf are not guaranteed that they are 4 Bytes aligned. Also,
it it not a good idea to cast type 'u8 *' to 'u32 *', except
we are sure that pointer type 'u8 *' is 4 Bytes aligned and
cast it to 'u32 *' will not pass memory boundary.
The problem is found when using fsl_qspi_write_data to write
registers in flash devices. The err msg:

The asm code which cause data abort is:

From the dump msg, r6 is not 4 Bytes aligned, and data abort exception.
So, Use mempcy but not unsafe type casting.

The QSPI clock rate was set without disabling the clock gate, the
randomly glitch may mess up the clock and there will be no clock output,
when kernel boot up the QSPI access will fail.
To debug this issueon i.MX6SX SDB, changed the u-boot bootscript to 'sf probe; reset'
to keep rebooting, the issue can be reproduced in 20 mins, set clock out
register in CCM and measured TP86, found there is no clock ouput.
To fix this bug, disable clock gate before changing clock rate.
NOTICE: QSPI2 and GPMI_BCH_INPUT_GPMI_IO share the same clock gate, need
to disable both of them.

So untile ldo bypass switch happened, these voltage setting is set in ldo-enable

From i2c spec, if device pull down the SDA line that causes
i2c bus dead, host can send out 9 clock to let device release
SDA.
But for some special device like pfuze100, it pull down SDA line
and the solution cannot take effort.
The patch just add NACK and STOP signal after 8 dummy clock, and pmic
can release SDA line after the recovery. Test case catch 375 times of
i2c hang, and all are recovered.

u-boot v2014 upstream codes have a problem in pfd reset (s_init function)
that imx6 Dual is not applied for PLL2 PFD2 reset. It is originated by
using dynamical cpu type checking and introducing two cpu types:
MXC_CPU_MX6Q and MXC_CPU_MX6D for iMX6 Dual/Quad platform.
Fixed this problem by checking the pre_periph_clk_sel and pre_periph2_clk
of CCM CBCMR register, if the PLL2 PFD0 or PLL2 PFD2 is used for the clock
source, do not reset this PFD to avoid system hang.

Let's use the i.MX common miscellaneous reset API
to reset the LCDIF block so that we may eliminate
a random hang issue at the arch_preboot_os() stage
when we disable the LCDIF. This patch also waits
for a VSYNC interrupt to guarantee the reset is
done at the VSYNC edge, which somehow makes the
LCDIF consume the display FIFO(?) and helps the
LCDIF work normally at the kernel stage.

imx6 q/dl/solo pcie would be failed to work properly in kernel, if
the pcie module is iniialized/enumerated both in uboot and linux
kernel.
rootcause:imx6 q/dl/solo pcie don't have the reset mechanism.
it is only be RESET by the POR. So, the pcie module only be
initialized/enumerated once in one POR.
Set to use pcie in kernel defaultly, mask the pcie config here.

Commit 3d622b78 (mx6: soc: Introduce set_ldo_voltage()) introduces
set_ldo_voltage() function that can be used to set the voltages

Prior to this commit there was a single set_vddsoc() which only configured the
VDDSOC regulator.

The kernel changes to fix the mmcblk index with USDHC controllers
as below:
mmcblk0 ---> USDHC1
mmcblk1 ---> USDHC2
mmcblk2 ---> USDHC3
mmcblk3 ---> USDHC4
So in u-boot, the "mmcroot" must be updated together.
When booting from SD/MMC device, change the "mmcroot" to
dynamically set according to the boot USDHC controller.
It is the same mechanism as "mmcdev" used for kernel image loading.
Therefore, the uboot, kernel image, dtb and rootfs are required
in same SD/MMC card.
To disable the mmc dynamical detection, set the "mmcautodetect" to "no",
then "mmcroot" and "mmcdev" will not be overwritten.
When booting from other devices which needs to load kernel, dtb and
rootfs from SD/MMC card, their "mmcdev" reset vaule is
CONFIG_SYS_MMC_ENV_DEV and "mmcroot" reset value is CONFIG_MMCROOT.
