[PATCH v2 5/5] rockchip: roc-pc-rk3399: Enable redundant environment

[Fabio Estevam via U-Boot <u-boot@lists.u-boot-project.org>]

From: Fabio Estevam <festevam@nabladev.com>

Use the final 64 KiB of the first 4 MiB of SPI NOR for two 32 KiB
U-Boot environment copies. Place the primary copy at 0x3f0000 and
the redundant copy at 0x3f8000.

Both copies are aligned to the 4 KiB erase-sector size and together
occupy 0x3f0000 through 0x3fffff. Redundancy protects the environment
against power loss or an interrupted update.
