      ARM: imx: cm_fx6: env: don't run boot scripts twice · 5a6440ca
      由 Christopher Spinrath 提交于 
      Boot scripts located in the root directory of the first partition of
USB, mmc, and SATA drives are executed twice: first by the distro boot
command and then by the legacy boot command. This may have weird side
effects if those scripts only change or extend the environment
(including parts of the boot command itself).

Removing the script execution from the legacy boot command has its own
caveats. For instance, the distro boot command may execute the boot.scr
on the mmc drive, then the boot.scr on the SATA drive, before the
legacy boot command actually boots from the mmc drive. However, the
current behavior would only execute the boot.scr once more before the
actual boot, but it does not prevent the script located on the SATA
drive from being executed, and thus, both scripts from being mixed up.

Considering that the legacy boot command is only in place to boot old
(standard) installations, let's go with the resolution having less
custom code and remove the script execution from the legacy boot
command.

      ARM: imx: cm_fx6: env: support distro boot command · 3ef5f671
      由 Christopher Spinrath 提交于 
      The current default environment of the cm_fx6 is not suitable for
booting modern distributions.

Instead of extending the custom environment, let's use the distro
boot command, which has been developed for precisely this use case.

If the distro boot command fails, fall back to the old behavior
(except for USB drives where the old behaviour is completely covered
by the distro boot command). That way it is still possible to create
"rescue SD cards" for old installations (e.g. if one messes up the
on-flash environment).

      ARM: imx: cm_fx6: env: use standard variables · 6b79f71c
      由 Christopher Spinrath 提交于 
      In preparation for supporting the distro boot command, introduce the
standard variables for specifying load addresses, which are documented
in README and doc/README.distro, and replace the custom variables
used so far with them.

Since the current address layout disregards an address for an initramfs,
also switch to the load addresses used and proven by other imx6 boards
(e.g. the wandboard and nitrogen6x), instead of going on with our own
way.

      imx: spl: Fix NAND bootmode detection · af104ae5
      由 Eran Matityahu 提交于 
      commit 20f14714 ("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.

      mx6: Add board mx6memcal for use in validating DDR · baefb63a
      由 Eric Nelson 提交于 
      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.

	https://community.nxp.com/docs/DOC-105652

File mx6memcal_defconfig configures the board for use with
mx6sabresd or mx6qsabreauto.
