6f6058bfd8 imx: imx-common: introduce boot auxiliary core
To boot a auxiliary core in asymmetric multicore system, introduce the
new command "bootaux" to do it. Example of boot auxliary core from
0x70000000 where stores the boot head information that should be
parsed by auxiliary core, "bootaux 0x70000000".
Introduce Kconfig option IMX_BOOTAUX.

40f4839ce1 imx_common: check for Serial Downloader in spl_boot_device
Check for bmode before reading the boot device
to check if a serial downloader is started,
and returns UART if the serial downloader is set,
letting SPL to wait for an image if
CONFIG_SPL_YMODEM_SUPPORT is set.

This allows to load again a SPL based board
with imx_usb_loader together with a tool
such as kermit.

ee3899aa6c imx: hab: add mx7 secure boot support
Add mx7 secure boot support, add helper macro IS_HAB_ENABLED_BIT
to get the corresponding bit mask per SoC (mx7 or mx6) to identify
if securue boot feature is enabled/disabled.

On authenticate_image only check for mmu enabled on mx6 SoC to
force pu_irom_mmu_enabled so ROM code can perform mmu cache flush
mx7 SoC ROM code does not have this issue as ROM enables cache support
based on fuse settings.

cf226d9942 imx-common: consider mux_ctrl_ofs when setting mux_mode
Some i.MXes use __NA_ or 0 to avoid setting mux_mode, but the following patch
only take i.MX6/7 into consideration.

"c3c8a5748897b24f18618047804317167a531dd3 imx-common: fix iomux settings"

Use is_soc_type(MXC_CPU_MX7) to avoid breaking other i.MXes when
setting mux_mode.

In this patch, switch to use "asm/imx-common/sys_proto.h" to avoid
build break for "is_soc_type" for vf610 and mx25.

71204e95ce i2c: mxc: refactor i2c driver and support dm
1. Introduce a new structure `struct mxc_i2c_bus`, this structure will
   used for non-DM and DM.
2. Remove `struct mxc_i2c_regs` structure, but use register offset to access
   registers based on `base` entry of `struct mxc_i2c_bus`.
3. Remove most `#ifdef I2C_QUIRK_REG`. Using driver_data to contain platform
   flags. A new flag is introduced, I2C_QUIRK_FLAG.
4. Most functions use `struct mxc_i2c_bus` as one of the parameters.
   Make most functions common to DM and non-DM, try to avoid duplicated code.
5. Support DM, but pinctrl is not included. Pinmux setting is still set
   by setup_i2c, but we do not need bus_i2c_init for DM.
6. struct i2c_parms and struct sram_data are removed.
7. Remove bus_i2c_read bus_i2c_write prototype in header file. The frist
   paramter of bus_i2c_init is modified to i2c index. Add new prototype
   i2c_idle_bus and force_bus_idle. Since bus_i2c_init is not good for
   DM I2C and pinctrl is missed, we use a weak function for i2c_idle_bus.
   Board file take the responsibility to implement this function, like this:
   "
   int i2c_idle_bus(struct mxc_i2c_bus *i2c_bus)
   {
	   if (i2c_bus->index == 0)
		   force_bus_idle(i2c_pads_info0);
	   else if (i2c_bus->index == 1)
		   force_bus_idle(i2c_pads_info1);
	   else
		   xxxxxx
   }
   "

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.

cd3c5896b6 imx: i2c: Zap unnecessary malloc() calls
The malloc() calls are unnecessary, just allocate the stuff on stack.
While at it, reorder the code a little, so that only one variable is
used for the text, use snprintf() instead of sprintf() and use %01d
as a formatting string to avoid any possible overflows.

dd1c8f1b5f sata: fix reset_sata for dwc_ahsata
- fix crash when sata device is not initialized
- remove disable_sata_clock() since it is not clear which clock for which
  device should be disabled here
- call disable_sata_clock() for mx6 in preboot_os instead

44b9841d78 arm: imx: stop sata on boot
Ideally, the Linux kernel should get the hardware in its most
untouched state. For the most part, U-Boot does not reset the various
subsystems it touches before boot, and usually Linux deals with it, but
on some boards (cm_fx6) the Linux kernel fails to detect the ssd
correctly if sata is used by U-Boot.

Power off sata on OS boot so that Linux will have a clean state to work
with.

32c81ea65c imx: consolidate set_chipselect_size function
Move MX5 specific set_chipselect_size function into generic i.MX part,
such that MX6 based boards are able to use this function as well.

While doing this the iomuxc gpr member needed to be consolidated between
MX5 and MX6.

Many boards use a minimal .cfg file in the SPL case.

Introduce spl_sd.cfg so that we can reuse it.
