[U-Boot] [PATCH V4 00/19] Introduce cm-fx6 board

[Nikita Kiryanov <nikita@compulab.co.il>]

This patch series introduces the mx6 based cm-fx6 board.
cm-fx6 comes with either single, dual, or quad core mx6 soc, and various dram
configurations.

First 12 patches are preparatory steps which include:
	- Cleanups and bug fixes for the mx6 dram config code
	- New functions and macros for enabling clocks, i2c setup, querying
	  the status of sata port, and more
	- Support for M25PE16 and M25PX16 spi flashes
	- sf probe command fix when using mxc_spi driver

NOTE: the correctness of this series depends on https://patchwork.ozlabs.org/patch/376095/

Changes in V4:
	- Rebase whole series over latest code (commit e49f14af1349eef94e41b636320bbfcace7403b5)
	- Patch "arm: mx6: add get_cpu_type()" is new to the series.
	- Adapt to use Kconfig
	- Initialize all ddr related structs statically
	- Don't #define CONFIG_SYS_L2CACHE_OFF for cm_fx6
	- Use load instead of fatload in environment scripts
	- Refactoring across board support patches (introduce some functions
	  in later patches, move/remove variables, coding style, etc. etc.);
	  Details in the patches

Changes in V3:
	- Remove CONFIG_SYS_TEXT_BASE from config file to not clash with the
	  one supplied by imx6_spl.h
	- Use (clr|set)bits_le32() where possible

Changes in V2:
	- Patch "spl: improve spi configuration" is replaced with "spl: replace
	  CONFIG_SPL_SPI_* with CONFIG_SF_DEFAULT_*", which kills CONFIG_SPL_SPI_*
	  defines in favor of using CONFIG_SF_DEFAULT_*.
	- Updated commit message of "sf: fix sf probe", renaming it in the process
	  to "spi: mxc: fix sf probe when using mxc_spi".
	- Return value handling.
	- Update commit message of "arm: mx6: ddr: configure MMDC for slow_pd"
	- Remove unnecessary line removal from arch/arm/cpu/armv7/mx6/ddr.c
	- Move probe_mmdc_config() code straight to dram_init()
	- Use imx6_spl.h
	- Use imx_ddr_size()
