a462c34602 imx:mx6ul add dram spl configuration and header file
1. Define two structures mx6ul_iomux_ddr_regs and mx6ul_iomux_grp_regs.
2. Add a new function mx6ul_dram_iocfg to configure dram io.
3. Refactor MMDC1 macro, discard "#ifdef CONFIG_MX6SX". Since
   only mmdc0 channel exists on i.MX6SX/UL, redefine MMDC1 macro support
   runtime check, but not hardcoding #ifdef macros.
4. Introduce mx6ul-ddr.h, which includes the register address for DRAM
   IO configuration.

43cb127b75 imx:mx6ul add clock support
1. Add enet, uart, i2c, ipg clock support for i.MX6UL.
2. Correct get_periph_clk, it should account for
   MXC_CCM_CBCDR_PERIPH_CLK2_PODF_MASK.
3. Refactor get_mmdc_ch0_clk to make all i.MX6 share one function,
   but not use 'ifdef'.
4. Use CONFIG_FSL_QSPI for enable_qspi_clk, but not #ifdef CONFIG_MX6SX.
5. Use CONFIG_PCIE_IMX for pcie clock settings, use CONFIG_CMD_SATA for
   sata clock settings. In this way, we not need "#if defined(CONFIG_MX6Q)
   || defined....", only need one CONFIG_PCIE_IMX in header file.

bc32fc699c imx: mx6ul: Update imx registers head file
1. Update imx register base address for i.MX6UL.
2. Remove duplicated MXS_APBH/GPMI/BCH_BASE.
3. Remove #ifdef for register addresses that equal to
   "AIPS2_OFF_BASE_ADDR + 0x34000" for different chips.
4. According fuse map, complete fuse_bank4_regs.
5. Move AIPS3_ARB_BASE_ADDR and AIPS3_ARB_END_ADDR out of #ifdef CONFIG_MX6SX,
   because we can use runtime check

19c6ec70c5 imx: mx6 add i2c4 clock support for i.MX6SX
Add I2C4 clock support for i.MX6SX. Since we use runtime check,
but not macro, we need to remove `#ifdef ..` in crm_regs.h, or
gcc will fail to compile the code succesfully.

Making the macros only for i.MX6SX open to other i.MX6x maybe not
a good choice, but we have runtime check.

Note that the IMX6SDLRM and the IMX6SXRM do not indicate this in the

In fast-exist mode the DLL is maintained such that it is ready again in about

0200020bc2 imx6: Added DEK blob generator command
Freescale's SEC block has built-in Data Encryption
Key(DEK) Blob Protocol which provides a method for
protecting a DEK for non-secure memory storage.
SEC block protects data in a data structure called
a Secret Key Blob, which provides both confidentiality
and integrity protection.
Every time the blob encapsulation is executed,
a AES-256 key is randomly generated to encrypt the DEK.
This key is encrypted with the OTP Secret key
from SoC. The resulting blob consists of the encrypted
AES-256 key, the encrypted DEK, and a 16-bit MAC.

During decapsulation, the reverse process is performed
to get back the original DEK. A caveat to the blob
decapsulation process,  is that the DEK is decrypted
in secure-memory and can only be read by FSL SEC HW.
The DEK is used to decrypt data during encrypted boot.

Commands added
--------------
  dek_blob - encapsulating DEK as a cryptgraphic blob

Commands Syntax
---------------
  dek_blob src dst len

    Encapsulate and create blob of a len-bits DEK at
    address src and store the result at address dst.
