* [U-Boot] [PATCH v3 0/2] IMX6: Add Gateworks Ventana support

  To: u-boot

Changes in v3:
  - update README fixing typo and removing Freescale document link
  - use debug() instead of printf()
  - be more explicit with hwmon error output and use macro for min/max percent
  - use #defines for GSC slave address and registers
  - remove extern from function prototype
  - moved gpio config into structure for better readability
  - use enum for eeprom bit configs and array to map to fdt property alias
  - add SATA regardless of cpu type
  - add FIT support regardless of flash type
  - display PMIC and device id in misc_init_r() instead of pmic driver

Changes in v2:
  - rebase on top of u-boot-imx
  - use switch..case for model specific init instead of strcmps
  - move checkboard to late init allowing i2c_setup to be moved to board_init()
    eeprom reading to be done after relocation, and move eeprom struct from
    data segment
  - move SPI/I2C init to board_init()
  - update README
  - remove unnecessary console overwrite function
  - fix multiline comment style and eliminate >80 char lines
  - eliminate unnecessary loop in board_mmc_init()
  - add missing copyright to clocks.cfg
  - avoid duplicating cfg files where no changes exist
  - added missing SPDX header to ventana_eeprom.h
  - use puts() instead of printf() for constant strings
  - remove messages regarding /dev/i2c-<n>
  - use get_ram_size() for determing ram_size
  - cleanup gpio configuration using tables for baseboard pinmux combinations
  - remove phy init errata as it doesn't pertain to use case
    (it is for 802.3az which IMX6 MAC does not support)
  - added pfuze100_pmic driver using PMIC API
  - moved GSC code (gsc command and i2c_read/i2c_write wrappers into own file)
  - allow user to quiet down some of the data displayed
  - remove display support for now - will revisit later
  - remove display of boot mode info - may revisit later
  - replace bitwise fields in eeprom structure with bit definitions
