[PATCH v2 1/2] colibri-imx6ull: improve env badblock management

[Marcel Ziswiler]

From: Francesco Dolcini <francesco.dolcini at toradex.com>

Use the complete 512kb (4 blocks) nand partition reserved for u-boot
environment instead of just the first block, this allows the module to
have a working environment even if 3 blocks are bad.

Changes in v2:
- Re-based on top of today's master taking our recent addition of the
  eMMC SKU into account.
- Just remove stale eMMC environment comment after Kconfig move.
