[U-Boot] [PATCH 00/11] MX6: SPL NAND support

[Tim Harvey]

Here is a stab at adding SPL NAND support for i.MX6. I tried to take into
account comments from previous attempts by others but there is still some
work to be done and in particular I need some help with the issue of dealing
with IMX6Q vs IMX6DL iomux in a way where the current defines can be shared
by SPL as well as imximage.

Some of these can be split out of the series if needed but I wanted to post
them originally as a series to provide full context.

The resulting SPL+u-boot.img has been tested on 4 different Ventana baseboards
with a variety of CPU and DDR3 options.

Tim Harvey (11):
  SPL: NAND: remove CONFIG_SYS_NAND_PAGE_SIZE
  SPL: NAND: add support for mxs nand
  MX6: provide linker script for SPL
  MX6: add common SPL configuration
  MX6: add boot device support SPL
  MX6: add struct for sharing data between SPL and uboot
  MX6: use macro building for MX6Q/MX6DL iomux regs
  MX6: add mmdc configuration for MX6Q/MX6DL
  IMX: add additional function for pinmux using an array
  ventana: auto-configure for IMX6Q vs IMX6DL
  ventana: switch to SPL
