after boot.
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.
Tested this code with android team colleague and did not find problem.

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.

Current only set VDDARM_IN@1.175V/VDDSOC_IN@1.175V before ldo bypass switch.
So untile ldo bypass switch happened, these voltage setting is set in ldo-enable
mode. But in datasheet, we need 1.15V + 125mV = 1.275V for VDDARM_IN. We need
to downgrade cpufreq to 400Mhz and restore after ldo bypass mode switch.

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.

Enable pcie support in uboot on imx6sx sd boards
- enable_pcie_clock should be call before ssp_en is set,
since that ssp_en control the phy_ref clk gate, turn on
it after the source of the pcie clks are stable.
- add debug info
- add rx_eq of gpr12 on imx6sx
- there are random link down issue on imx6sx. It's

Commit 3d622b78 (mx6: soc: Introduce set_ldo_voltage()) introduces
set_ldo_voltage() function that can be used to set the voltages
of any of the three LDO regulators controlled by the PMU_REG_CORE register.
Prior to this commit there was a single set_vddsoc() which only configured the
VDDSOC regulator.
Update the comments to align with the new set_ldo_voltage() implementation.

There are about 0.02% percentage on some imx6q/dl/solo
hw boards, random pcie link down when warm-reset is used.
Make sure to clear the ref_ssp_en bit16 of gpr1 before
warm-rst, and set ref_ssp_en after the pcie clks are
stable to workaround it.
rootcause:
* gpr regisers wouldn't be reset by warm-rst, while the
ref_ssp_en is required to be reset by pcie.
(work-around in u-boot)
* ref_ssp_en should be set after pcie clks are stable.

iMX6SX has different enet system clocks with iMX6SL, and has two ENET
controllers. So update clocks and soc APIs accordingly to support this
features.
1. Modify the clock API "enable_enet_clock" to enable enet system clock
for enet controllers.
2. Enet RGMII TX clock source may come from external or internal PLL.
By default, use the external phy CLK_25M output as TX clock source.
When using internal PLL as source, the function enable_fec_anatop_clock
must be called to enable clock for each enet controller.
3. Modify the MAC address function "imx_get_mac_from_fuse" to get either
ENET MAC address.
4. Add configuration "CONFIG_FEC_MXC_25M_REF_CLK" to enable ENET 25Mhz
reference clock.
5. Modify imx6slevk BSP to fit the new APIs.

U-Boot has supported two kinds of asm-offsets.h.
One is generic for all architectures and its source is located at
./lib/asm-offsets.c.
The other is SoC specific and its source is under SoC directory.
The problem here is that only boards with SoC directory can use
the asm-offsets infrastructure.
Putting asm-offsets.c right under CPU directory does not work.
Now a new demand is coming. PowerPC folks want to use asm-offsets.
But no PowerPC boards have SoC directory.
It seems inconsistent that some boards add asm-offsets.c to SoC
directoreis and some to CPU directories.
It looks more reasonable to put asm-offsets.c under arch/$(ARCH)/lib.
This commit merges asm-offsets.c under SoC directories into
arch/$(ARCH)/lib/asm-offsets.c.
By the way, I doubt the necessity of some entries in asm-offsets.c.
I am leaving refactoring to the board maintainers.
Please check "TODO" in the comment blocks in
arch/{arm,nds32}/lib/asm-offsets.c.

This patch adds the groundwork for generating signed BootStream, which
can be used by the HAB library in i.MX28. We are adding a new target,
u-boot-signed.sb , since the process for generating regular non-signed
BootStream is much easier. Moreover, the signed bootstream depends on
external _proprietary_ _binary-only_ tool from Freescale called 'cst',
which is available only under NDA.
To make things even uglier, the CST or HAB mandates a kind-of circular
dependency. The problem is, unlike the regular IVT, which is generated
by mxsimage, the IVT for signed boot must be generated by hand here due
to special demands of the CST. The U-Boot binary (or SPL binary) and IVT
are then signed by the CST as a one block. But here is the problem. The
size of the entire image (U-Boot, IVT, CST blocks) must be appended at
the end of IVT. But the size of the entire image is not known until the
CST has finished signing the U-Boot and IVT. We solve this by expecting
the CST block to be always 3904B (which it is in case two files, U-Boot
and the hand-made IVT, are signed in the CST block).
