The PCIe support in uboot would bring failures in i.MX6SX PCIe
EP/RC validations. Disable PCIe support in uboot here.
RootCause: The bit10(ltssm_en) of GPR12 would be set in uboot,
thus the i.MX6SX PCIe EP would be cheated that the other i.MX6SX
PCIe RC had been configured and trying to setup PCIe link
directly, although the i.MX6SX RC is not properly configured
at that time.
PCIe can be supported in uboot, if the i.MX6SX PCIe EP/RC
validation is not running.Signed-off-by: Richard Zhu

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

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.
Remove the mask freely, if the uboot pcie functions, rather than
the kernel's, are required.Signed-off-by: Richard Zhu

Android supports to two ways to pass serialno:
1. ATAG_SERIAL
2. "androidboot.serialno=" argument in boot commandline.Since we support the DTB for android, so the ATAGS can't work. We have to choose
the second way.

The kernel changes to fix the mmcblk index with USDHC controllers
as below:
mmcblk0 ---> USDHC1
mmcblk1 ---> USDHC2
mmcblk2 ---> USDHC3
mmcblk3 ---> USDHC4So 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.Signed-off-by: Ye.Li

The NOR flash PC28F00AG18 has 512 of 256KB erase blocks which are
locked after power on reset. Change the 17x17 ARM2 configurations
to match the flash parameters, and enable the CONFIG_SYS_FLASH_PROTECTION
to allow write to the flash.The EIM-NOR on 17x17 ARM2 board uses MUXed mode. This has less
effort on board rework.When boot from EIM-NOR, set SW8, SW7, SW5 to all off.
