Use PHASE_ as the symbol to select a particular XPL build. This means
that SPL_TPL_ is no-longer set.
Update the comment in bootstage to refer to this symbol, instead of
SPL_

Move MTD-related lines out of the root Makefile. Put them in their
respective directories. Enclose some of these new lines to skip them
when building the SPL. MTD core files and some MTD device drivers are
compiled in a mtd.o object and included in the final object only if
MTD support is required (there are two different symbols for that, one
for U-Boot and one for the SPL).
Now that all defconfigs have been fixed, we can stop the logic where
enabling a command selects the core files to compile. This logic is
broken since selecting a symbol with a 'depends on' will not enforce
this secondary dependency.

NAND flavors, like serial and parallel, have a lot in common and would
benefit to share code. Let's move raw (parallel) NAND specific code in a
raw/ subdirectory, to ease the addition of a core file in nand/ and the
introduction of a spi/ subdirectory specific to SPI NANDs.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

A patch for NAND uclass support was proposed about half a year ago:
https://patchwork.ozlabs.org/patch/722282/
It was not merged and I do not see on-going work for this.
Without DM-based probing, we need to set up pinctrl etc. in an ad-hoc
way and give lots of crappy CONFIG options for base addresses and
properties, which are supposed to be specified by DT. This is painful.
This commit just provides a probe hook to retrieve "reg" from DT and
allocate private data in a DM manner. This DT driver is not essentially
a NAND driver, in fact it is (ab)using UCLASS_MISC. Once UCLASS_NAND is
supported, it would be possible to migrate to it.

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.

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/[email protected]/msg175762.html
Otherwise it will not compile.
Tested on the Marvell Armada XP DB-MV784MP-GP eval board.

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

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.

platforms
ELM hardware engine which is used for ECC error detection, is present on all
latest OMAP SoC (like OMAP4xxx, OMAP5xxx, DRA7xxx, AM33xx, AM43xx). Thus ELM
driver should be moved to common drivers/mtd/nand/ folder so that all SoC
having on-chip ELM hardware engine can re-use it.
This patch has following changes:
- mv arch/arm/include/asm/arch-am33xx/elm.h arch/arm/include/asm/omap_elm.h
- mv arch/arm/cpu/armv7/am33xx/elm.c drivers/mtd/nand/omap_elm.c
- update Makefiles
- update #include <asm/elm.h>
- add CONFIG_NAND_OMAP_ELM to compile driver/mtd/nand/omap_elm.c
and include in all board configs using AM33xx SoC platform.

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.
