[U-Boot] [PATCH 00/12] MX6: SPL NAND support

[Tim Harvey]

This series adds some necessary framework for IMX6 SPL support. The series
includes support for NAND SPL and has been tested with MMC as well. I have
tested this on five differing Ventana baseboards with a variety of memory
(32bit 512MB, 32bit 1024MB, 64bit 1024MB) and CPU configurations (IMX6Q,
IMX6DL, IMX6S).

v2:
 - use compatible linker script instead of creating new one
 - remove structure passing data from SPL to u-boot
 - remove dependence on mtdpart, mtdcore, nand_util, nand_ecc, nand_base
   and nand_bbt to bring SPL down in size. This reduced codesize by about 32k
   where now mxs_spl_nand is about 12k total
 - adjust CONFIG_SPL_TEXT_BASE, CONFIG_SPL_STACK and CONFIG_SPL_MAX_SIZE
   to accomodate the IMX6SOLO/DUALLITE which have half the iRAM of the
   IMX6DUAL/IMX6QUAD
 - move boot dev detection into imx-common/spl.c
 - move macros for using pinmux array into iomux-v3.h
 - remove missing/unnecessary include
 - revert mtdparts change
 - use get_ram_size() to detect memory
 - add support for MX6SOLO and MX6DUAL
 - set CS0_END for 4GB so get_ram_size() works
 - updated DDR3 calibration values for ventana boards
 - fixed build issue - only compile spl if doing spl build
 - fixed line length issue in README
 - remove CONFIG_SPL* conditions and conditionally compile instead
 - removed prints for CPU type and DRAM size/width - uboot will print these l
 - removed unused gw_ventana_spl.cfg
 - use common read_eeprom function
 - added MMC support to SPL
 - added Masahiro Yamada's boot mode consolidation patch
   http://patchwork.ozlabs.org/patch/341817 and rebase on top of it

Masahiro Yamada (1):
  spl: consolidate arch/arm/include/asm/arch-*/spl.h

Tim Harvey (11):

  IMX: add comments and remove unused struct fields
  MX6: add structs for mmdc and ddr iomux registers
  MX6: add mmdc configuration for MX6Q/MX6DL
  IMX: add additional function for pinmux using an array
  imx: ventana: split read_eeprom into standalone file
  imx: ventana: auto-configure for IMX6Q vs IMX6DL
  imx: ventana: switch to SPL
