As QSPI and IFC are pin-multiplexed on LS1021A, only IFC is supported
in SD boot now. For the customer's demand, QSPI needs to be supported
in SD boot too.

This patch adds QSPI or IFC support in SD boot according to the
corresponding defconfig. For detail, ls1021aqds_sdcard_ifc_defconfig
is used to support IFC in SD boot and ls1021aqds_sdcard_qspi_defconfig
is used to support QSPI in SD boot.

The output ring needs to be invalidated before enqueuing the job to SEC.
While allocation of space to output ring, it should be taken care that the
size is cacheline size aligned inorder to prevent invalidating valid data.

The patch also correct the method of aligning end of structs while flushing caches

    Since start = align(start_of_struct), it is incorrect to assign
    end = align(start + struct_size). It should instead be,
    end = align(start_of_struct + struct_size).

In current design, if any peripheral was assigned to both A7 and M4,
it will receive ipg_stop or ipg_wait when any of the 2 platforms
enter low power mode. We will have a risk that, if A7 enter wait,
M4 enter stop, peripheral will have chance to get ipg_stop and ipg_wait
asserted same time. Also if M4 enters stop mode, A7 will have no
chance to access the peripheral.
There are 26 peripherals affected by this IC issue:
SIM2(sim2/emvsim2)
SIM1(sim1/emvsim1)
UART1/UART2/UART3/UART4/UART5/UART6/UART7
SAI1/SAI2/SAI3
WDOG1/WDOG2/WDOG3/WDOG4
GPT1/GPT2/GPT3/GPT4
PWM1/PWM2/PWM3/PWM4
ENET1/ENET2
Software Workaround:
The solution is to set the peripherals to Domain0 by A core, since A core
in Domain0. The peripherals which will be used by M4, will be set to Domain1
by M4.
For example, A core set WDOG4 to domain0, but when M4 boots up, M4 will
set WDOG4 to domain1, because M4 will use WDOG4.

So the peripherals are not shared by them. This way requires
the uboot implemented the RDC driver and set the 26 IPs above
to domain 0 only. M4 image will set the M4 to domain 1 and
set peripheral which it will use to domain 1.

This patch enables the CONFIG_IMX_RDC and CONFIG_IMX_BOOTAUX for
i.MX7D SABRESD board, and setup the 26 IP resources to domain 0.

Introduce pinctrl for i.MX6
1. pinctrl-imx.c is for common usage. It's used by i.MX6/7.
2. Add PINCTRL_IMX PINCTRL_IMX6 Kconfig entry.
3. To the pinctrl_ops implementation, only set_state is implemented.
   To i.MX6/7, the pinctrl dts entry is as following:
&iomuxc {
        pinctrl-names = "default";

        pinctrl_csi1: csi1grp {
                fsl,pins = <
                MX6UL_PAD_CSI_MCLK__CSI_MCLK            0x1b088
                MX6UL_PAD_CSI_PIXCLK__CSI_PIXCLK        0x1b088
                MX6UL_PAD_CSI_VSYNC__CSI_VSYNC          0x1b088
                >;
        };

        [.....]
};
  there is no property named function or groups. So pinctrl_generic_set_state
  can not be used here.
5. This driver is a simple implementation for i.mx iomux controller,
   only parse the fsl,pins property and write value to registers.
6. With DEBUG enabled, we can see log when "i2c bus 0":
   "
   set_state_simple op missing
   imx_pinctrl_set_state: i2c1grp
   mux_reg 0x14c, conf_reg 0x3bc, input_reg 0x5d8, mux_mode 0x0, input_val 0x1, config_val 0x4000007f
   write mux: offset 0x14c val 0x10
   select_input: offset 0x5d8 val 0x1

Intel IvyBridge FSP seems to be buggy that it does not report memory
used by FSP itself as reserved in the resource descriptor HOB. The
FSP specification does not describe how resource descriptor HOBs are
generated by the FSP to describe what memory regions. It looks newer
FSPs like Queensbay and BayTrail do not have such issue. This causes
U-Boot relocation overwrites the important boot service data which is
used by FSP, and the subsequent call to fsp_notify() will fail.

To resolve this, we find out the lowest memory base address allocated
by FSP for the boot service data when walking through the HOB list in
fsp_get_usable_lowmem_top(). Check whether the memory top address is
below the FSP HOB list, and if not, use the lowest memory base address
allocated by FSP as the memory top address.
