- DMA operations not supported. Remove it
- Adapt DT parsing to U-Boot APIs
v2:
- Add linux reference version in the commit message from which the
driver is ported from
- Reword the commit message to describe the changes clearly

The EBI is used to access peripherals like NAND, SRAM, NOR etc. Add
this driver to probe the nand flash controller. This is a dummy driver
and not yet a complete device driver for EBI.

This patch series adds support for NAND flash. The series adds DM
support and replaces the existing NAND driver NAND_ATMEL. The drivers
are ported from Linux based on the work done by Boris brezillon
Balamanikandan Gunasundar (9):
nand: atmel: Add DM based NAND driver
nand: atmel: Add pmecc
This implementation is ported from the rework done by Boris Brezillon
in Linux. The driver is tested in sam9x60ek, sama5d3_xplained,
sam9x75eb and sama7g54-ddr3-eb.
