  Since the qspi2_clk_root is the root clock of u_gpmi_bch_input_gpmi_io_clk,
  before switching the parent of qspi2_clk_root, we must gate off it.

• 7feb8533f   ENGR00320125 iMX6: Change to use dynamical mmcroot ... Browse Code »

  The kernel changes to fix the mmcblk index with USDHC controllers
  as below:
  mmcblk0 ---> USDHC1
  mmcblk1 ---> USDHC2
  mmcblk2 ---> USDHC3
  mmcblk3 ---> USDHC4

  So in u-boot, the "mmcroot" must be updated together.

  When booting from SD/MMC device, change the "mmcroot" to
  dynamically set according to the boot USDHC controller.
  It is the same mechanism as "mmcdev" used for kernel image loading.
  Therefore, the uboot, kernel image, dtb and rootfs are required
  in same SD/MMC card.
  To disable the mmc dynamical detection, set the "mmcautodetect" to "no",
  then "mmcroot" and "mmcdev" will not be overwritten.

  When booting from other devices which needs to load kernel, dtb and
  rootfs from SD/MMC card, their "mmcdev" reset vaule is
  CONFIG_SYS_MMC_ENV_DEV and "mmcroot" reset value is CONFIG_MMCROOT.

• da0e5e9e1   ENGR00319772 iMX6SX:ARM2: Add EIM-NOR support for 17x17 ARM2 board ... Browse Code »

  The NOR flash PC28F00AG18 has 512 of 256KB erase blocks which are
  locked after power on reset. Change the 17x17 ARM2 configurations
  to match the flash parameters, and enable the CONFIG_SYS_FLASH_PROTECTION
  to allow write to the flash.

  The EIM-NOR on 17x17 ARM2 board uses MUXed mode. This has less
  effort on board rework.

  When boot from EIM-NOR, set SW8, SW7, SW5 to all off.

  Currently, kernel common regulator framework can't support setting pmic mode
  by common DTS, so move the related code to u-boot firstly.

  Enable the "CONFIG_CMD_BMODE" and add BSP support.

  "bmode" supports to reboot:
  SD4, QSPI2 (SABRESD)
  SD2, SD3, eMMC, QSPI2, NAND, SPINOR (17x17 ARM2)
  SD1, QSPI2, SPINOR, EIMNOR (19x19 ARM2)

  BTW: Board rework is needed on ARM2 for NAND, SPINOR or EIMNOR boot.

  Add BSP codes for iMX6SX 17x17 ARM2 board to support SD/MMC,
  USB, QSPI2 NOR Flash, SPI NOR flash, NAND Flash, Ethernet, I2C
  ,PMIC and M4 command boot (bootaux).

  Some features has conflicts, so can't be enabled at same time:
  QSPI NAND pin conflict
  QSPI SPI-NOR u-boot driver conflict
  SPI-NOR SD2 pin conflict

  Add board build targets of 17x17 ARM2 for boot device:
  mx6sx_17x17_arm2 --- SD/MMC/eMMC
  mx6sx_17x17_arm2_spinor --- SPINOR on ECSPI4 CS0
  mx6sx_17x17_arm2_nand --- NAND flash
  mx6sx_17x17_arm2_qspi2 --- QuadSPI2 NOR flash
