Hi,
This series adds support for the BCH controller and NAND devices on
the Ingenic JZ4780 SoC.
Tested on the MIPS Creator Ci20 board. All dependencies are now in
mainline.
This version of the series is based on 4.3-rc1.
Review and feedback welcome.
Thanks,
Alex

Add DT bindings for NAND devices connected to the NEMC on JZ4780 SoCs,
as well as the hardware BCH controller, used by the jz4780_{nand,bch}
drivers.

Add device tree nodes for the NEMC and BCH to the JZ4780 device tree,
and make use of them in the Ci20 device tree to add a node for the
board's NAND.
Note that since the pinctrl driver is not yet upstream, this includes
neither pin configuration nor busy/write-protect
From: Alex Smith
Add a driver for NAND devices connected to the NEMC on JZ4780 SoCs, as
well as the hardware BCH controller. DMA is not currently implemented.
While older 47xx SoCs also have a BCH controller, they are incompatible
with the one in the 4780 due to differing register/bit positions
From: Alex Smith
If nand_wait_ready() times out, this is silently ignored, and its
caller will then proceed to read from/write to the chip before it is
ready. This can potentially result in corruption with no indication as
to why.
While a 20ms timeout seems like it should be plenty enough

v4 -> v5:
- Bump RB_DELAY up to be sufficient for the driver to work withou
. Use of the NAND relies on the boot loader to have left the pins
configured in a usable state, which should be the case when booted
from the NAND.

Hi,
This series adds support for the BCH controller and NAND devices on
the Ingenic JZ4780 SoC.
Tested on the MIPS Creator Ci20 board. All dependencies are now in
mainline.
This version of the series is based on current mainline (pre 4.3-rc1).
Review and feedback welcome.
Thanks,

Hi Ezequiel,
Thanks for reviewing the series.

v3 -> v4:
- Rebase to 4.2-rc4
- Change ECC_HW_OOB_FIRST to ECC_HW, reading
additional patch to fix an issue that was encountered in the
external Ci20 3.18 kernel branch.
Review and feedback welcome.
Thanks,

The cmdline_size field in setup_header is listed as read-only, and is
never read by the kernel. Therefore, there is no need for it to be set
by a boot loader implementing the EFI handover protocol, so remove it
from the list of fields required to be set by a boot loader.
