e526861687 sunxi_nand_spl: Rename SPL_NAND_SUNXI to NAND_SUNXI
We eventually want to add full nand support, since it makes no sense
to build SPL with nand support and u-boot without, or the other way
around, a single option will suffice.

Renaming the Kconfig option now makes things easier when we add full
nand support in the future.

The "obj-$(CONFIG_NAND_SUNXI) += sunxi_nand_spl.o" is moved to an
"ifdef CONFIG_SPL_BUILD" block in the Makefile.

873960c89e mtd: nand: Add mvebu (PXA / AXP / A38x) NAND device driver
Cloned from the Linux driver v4.2.0-rc2. Plus some patches from
Antoine Tenart enabling controller initialization and ONFI timing
support:

http://lists.infradead.org/pipermail/linux-mtd/2015-July/060197.html

Please note that this driver needs the Linux NAND subsystem sync to v4.1
from Scott to be applied:

https://www.mail-archive.com/u-boot@lists.denx.de/msg175762.html

Otherwise it will not compile.

Tested on the Marvell Armada XP DB-MV784MP-GP eval board.

d3963721d9 nand: Sync with Linux v4.1
Update the NAND code to match Linux v4.1.  The previous sync was
from Linux v3.15 in commit 4e67c57125.

CONFIG_SYS_NAND_RESET_CNT is removed, as the upstream Linux code now
has its own timeout.  Plus, CONFIG_SYS_NAND_RESET_CNT was undocumented
and not selected by any board.

dcfd37e5ef nand: lpc32xx: add SLC NAND controller support
The change adds support of LPC32xx SLC NAND controller.

LPC32xx SoC has two different mutually exclusive NAND controllers to
communicate with single and multiple layer chips.

This simple driver allows to specify NAND chip timings and defines
custom read_buf()/write_buf() operations, because access to 8-bit data
register must be 32-bit aligned.

Support of hardware ECC calculation is not implemented (data
correction is always done by software), since it requires a working
DMA engine.

The driver can be included to an SPL image.

ELM hardware engine which is used for ECC error detection, is present on all

- mv arch/arm/cpu/armv7/am33xx/elm.c drivers/mtd/nand/omap_elm.c

956b03e180 mtd: nand: add driver for diskonchip g4 nand flash
This patch adds a driver for the diskonchip G4 nand flash device.  It is based
on the driver from the linux kernel.

This also includes a separate SPL driver.  A separate SPL driver is used because
the device operates in a different mode (reliable mode) when loading a boot
image, and also because the storage format of the boot image is different from
normal data (pages are stored redundantly).  The SPL driver basically mimics how
a typical IPL reads data from the device.  The special operating mode and
storage format are used to compensate for the fact that the IPL does not contain
the BCH ecc decoding algorithm (due to size constraints).  Although the u-boot
SPL *could* use ecc, it operates like an IPL for the sake of simplicity and
uniformity, since the IPL and SPL share the task of loading the u-boot image.
As a side benefit, the SPL driver is very small.

The reverted patch should be resubmitted with documentation, and with the

start by looking at what NAND driver the board selects, and whether

52f90dad60 nand: Freescale Integrated Flash Controller NAND support
Add NAND support (including spl) on IFC, such as is found on the p1010.

Note that using hardware ECC on IFC with small-page NAND (which is what
comes on the p1010rdb reference board) means there will be insufficient
OOB space for JFFS2, since IFC does not support 1-bit ECC.  UBI should
work, as it does not use OOB for anything but ECC.

When hardware ECC is not enabled in CSOR, software ECC is now used.

6d8962e814 Switch from archive libraries to partial linking
Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

165fa406ad SPEAr : nand driver support for SPEAr SoCs
SPEAr SoCs contain an FSMC controller which can be used to interface
with a range of memories eg. NAND, SRAM, NOR.
Currently, this driver supports interfacing FSMC with NAND memories

36fab997d8 mxc_nand: add nand driver for MX2/MX3
Driver for NFC NAND controller found on Freescale's MX2 and MX3
processors. Ported from Linux. Tested only with i.MX27 but should
works with other MX2 and MX3 processors too.

be33b046b5 Remove legacy NAND and disk on chip code.
Legacy NAND had been scheduled for removal.  Any boards that use this
were already not building in the previous release due to an #error.

The disk on chip code in common/cmd_doc.c relies on legacy NAND,
and it has also been removed.  There is newer disk on chip code
in drivers/mtd/nand; someone with access to hardware and sufficient
time and motivation can try to get that working, but for now disk
on chip is not supported.
