4467ae6c28 arm: imx: hab: Make authenticate_image() return zero on open boards
The BootROM will not successfully process a HAB image passed by u-boot
unless the board has been set into locked mode. Some of the existing usages
of authenticate_image() expect and rely on unlocked boards doing the
following

1. Not calling into the BootROM authenticate_image() callback
2. Returning a pass status for authenticate_image() calls anyway

A previous patch removed the necessity to call into imx_hab_is_enabled()
twice. This patch ensures the reliance on authenticate_image() returning
zero is maintained.

imx_hab_is_enabled().

c5800b2541 arm: imx: hab: Fix authenticate_image input parameters
u-boot command "hab_auth_img" tells a user that it takes

- addr - image hex address
- offset - hex offset of IVT in the image

but in fact the callback hab_auth_img makes to authenticate_image treats
the second 'offset' parameter as an image length.

Furthermore existing code requires the IVT header to be appended to the end
of the image which is not actually a requirement of HABv4.

This patch fixes this situation by

1: Adding a new parameter to hab_auth_img
   - addr   : image hex address
   - length : total length of the image
   - offset : offset of IVT from addr

2: Updates the existing call into authenticate_image() in
   arch/arm/mach-imx/spl.c:jump_to_image_no_args() to pass
   addr, length and IVT offset respectively.

This allows then hab_auth_img to actually operate the way it was specified
in the help text and should still allow existing code to work.

It has the added advantage that the IVT header doesn't have to be appended
to an image given to HAB - it can be prepended for example.

Note prepending the IVT is what u-boot will do when making an IVT for the
BootROM. It should be possible for u-boot properly authenticate images
made by mkimage via HAB.

This patch is the first step in making that happen subsequent patches will
focus on removing hard-coded offsets to the IVT, which again is not
mandated to live at the end of a .imx image.

9535b3975f arm: imx: hab: Fix authenticate_image result code
authenticate_image returns 1 for success and 0 for failure. That result
code is mapped directly to the result code for the command line function
hab_auth_img - which means when hab_auth_img succeeds it is returning
CMD_RET_FAILURE (1) instead of CMD_RET_SUCCESS (0).

This patch fixes this behaviour by making authenticate_image() return 0 for
success and 1 for failure. Both users of authenticate_image() as a result
have some minimal churn. The upshot is once done when hab_auth_img is
called from the command line we set $? in the standard way for scripting
functions to act on.

Fixes: 36c1ca4d46 ("imx: Support i.MX6 High Assurance Boot
authentication")

adbb051f08 arm: imx: hab: Make authenticate_image return int
Both usages of authenticate_image treat the result code as a simple binary.
The command line usage of authenticate_image directly returns the result
code of authenticate_image as a success/failure code.

Right now when calling hab_auth_img and test the result code in a shell a
passing hab_auth_img will appear to the shell as a fail.

The first step in fixing this behaviour is to fix-up the result code return
by authenticate_image() itself, subsequent patches fix the interpretation
of authenticate_image so that zero will return CMD_RET_SUCCESS and non-zero
will return CMD_RET_FAILURE.

The first step is fixing the return type in authenticate_image() so do that
now.

dbeaa1d131 ARM: imx: cm_fx6: export board and soc info to env
Like many other i.MX6 based boards, there are multiple variants of
the cm-fx6 module featuring different SoC variants. Furthermore, the
module can be paired with multiple baseboards.

At the same time modern distribution like Fedora require U-Boot to
select a proper devicetree which depends on the SoC variant and the
baseboard.

Thus, export the SoC variant and the actual board to the environment
following the conventions of other i.MX6 devices (e.g. the NXP boards)
such that the environment can select a devicetree file to load.

For now, we only know for sure that the cm-fx6 module and the SB-fx6m
baseboard amount to a Utilite Computer variant (depending on the SoC).
Further combinations may be added in the future; e.g. CompuLab's
evaluation board once someone can verify the identification string
stored in its eeprom.

af104ae5b8 imx: spl: Fix NAND bootmode detection
commit 20f1471416 ("imx: spl: Update NAND bootmode detection bit")
broke the NAND bootmode detection by checking if
BOOT_CFG1[7:4] == 0x8 for NAND boot mode.
This commit essentially reverts it, while using the IMX6_BMODE_*
macros that were introduced since.

Tables 8-7 & 8-10 from IMX6DQRM say the NAND boot mode selection
is done when BOOT_CFG1[7] is 1, but BOOT_CFG1[6:4] is not
necessarily 0x0 in this case.
Actually, NAND boot mode is when 0x8 <= BOOT_CFG1[7:4] <= 0xf,
like it was in the code before.

baefb63a13 mx6: Add board mx6memcal for use in validating DDR
This is a virtual "board" that uses configuration files and
Kconfig to define the memory layout used by a real board during
the board bring-up process.

It generates an SPL image that can be loaded using imx_usb or
SB_LOADER.exe.

When run, it will generate a set of calibration constants for
use in either or both a DCD configuration file for boards that
use u-boot.imx or struct mx6_mmdc_calibration for boards that
boot via SPL.

In essence, it is a configurable, open-source variant of the
Freescale ddr-stress tool.

e203dcf23e imx_common: detect USB serial downloader reliably
The current mechanism using SCR/GPR registers work well when
the serial downloader boot mode has been selected explicitly
(either via boot mode pins or using bmode command). However,
in case the system entered boot ROM due to unbootable primary
boot devices (e.g. empty eMMC), the SPL fails to detect that
it has been downloaded through serial loader and tries to
continue booting from eMMC:
  Trying to boot from MMC1
  mmc_load_image_raw_sector: mmc block read error
  SPL: failed to boot from all boot devices
  ### ERROR ### Please RESET the board ###

The only known way to reliably detect USB serial downloader
is by checking the USB PHY receiver block power state...

Also replace BMODE_UART with BMODE_RESERVED, which is more appropriate.
Commit 96aac843b6 ("imx: Use IMX6_BMODE_* macros instead of numericals")
added macros for boot modes, in the process the reserved boot mode got
named BMODE_UART. We use the reserved boot mode in the bmode command to
let the boot ROM enter serial downloader recovery mode. But this is only
a side effect, the actual boot mode is reserved...

c1c3fe2307 env: Convert CONFIG_ENV_IS_IN... to a choice
At present we support multiple environment drivers but there is not way to
select between them at run time. Also settings related to the position and
size of the environment area are global (i.e. apply to all locations).

Until these limitations are removed we cannot really support more than one
environment location. Adjust the location to be a choice so that only one
can be selected. By default the environment is 'nowhere', meaning that the
environment exists only in memory and cannot be saved.

Also expand the help for the 'nowhere' option and move it to the top since
it is the default.

2be296538e Convert CONFIG_ENV_IS_IN_MMC/NAND/UBI and NOWHERE to Kconfig
This converts the following to Kconfig:
   CONFIG_ENV_IS_IN_MMC
   CONFIG_ENV_IS_IN_NAND
   CONFIG_ENV_IS_IN_UBI
   CONFIG_ENV_IS_NOWHERE

In fact this already exists for sunxi as a 'choice' config. However not
all the choices are available in Kconfig yet so we cannot use that. It
would lead to more than one option being set.

In addition, one purpose of this series is to allow the environment to be
stored in more than one place. So the existing choice is converted to a
normal config allowing each option to be set independently.

There are not many opportunities for Kconfig updates to reduce the size of
this patch. This was tested with

   ./tools/moveconfig.py -i CONFIG_ENV_IS_IN_MMC

And then manual updates.  This is because for CHAIN_OF_TRUST boards they
can only have ENV_IS_NOWHERE set, so we enforce that via Kconfig logic
now.
