27d706937a ARM: zynq: Fix invalid check on NAND_CMD_NONE.
The end_cmd field in the variables cmd_phase_addr and data_phase_addr
contains the value 0xFF when the end_cmd equals NAND_CMD_NONE. This
should be 0x00.

This is caused by comparing NAND_CMD_NONE (int) with end_cmd (u8).
end_cmd will be promoted by the int value -1 and therefore is not equal
to 0xFF. Solved by casting NAND_CMD_NONE to u8 which will avoid int
promotion.

9d86b89c59 dma-mapping: move dma_map_(un)single() to <linux/dma-mapping.h>
The implementation of dma_map_single() and dma_unmap_single() is
exactly the same for all the architectures that support them.

Factor them out to <linux/dma-mapping.h>, and make all drivers to
include <linux/dma-mapping.h> instead of <asm/dma-mapping.h>.

If we need to differentiate them for some architectures, we can
move the generic definitions to <asm-generic/dma-mapping.h>.

Add some comments to the helpers. The concept is quite similar to
the DMA-API of Linux kernel. Drivers are agnostic about what is
going on behind the scene. Just call dma_map_single() before the
DMA, and dma_unmap_single() after it.

336d4615f8 dm: core: Create a new header file for 'compat' features
At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in

which needs to use the system malloc() in some files.

21d4a3ca54 mtd: rawnand: denali_dt: insert udelay() after reset deassert
When the reset signal is de-asserted, the HW-controlled bootstrap
starts running unless it is disabled in the SoC integration.
It issues some commands to detect a NAND chip, and sets up registers
automatically. Until this process finishes, software should avoid
any register access.

Without this delay function, some of UniPhier boards hangs up while
executing nand_scan_ident(). (denali_read_byte() is blocked)

9925df051a mtd: rawnand: denali: Do not reset the block before booting the kernel
The Denali NAND driver in mainline Linux currently cannot deassert the
reset. The upcoming Linux 5.6 will support the reset controlling, and
also set up SPARE_AREA_SKIP_BYTES correctly. So, the Denali driver in
the future kernel will work without relying on any bootloader or firmware.
However, we still need to take care of stable kernel versions for a while.
U-boot should not assert the reset of this controller.

33672c970b mtd: rawnand: denali-spl: Add missing hardware init on SoCFPGA
On Altera SoCFPGA, upon either cold-boot or power-on reset, the
Denali NAND IP is initialized by the BootROM ; upon warm-reset,
the Denali NAND IP is NOT initialized by BootROM. In fact, upon
warm-reset, the SoCFPGA BootROM checks whether the SPL image in
on-chip RAM is valid and if so, completely skips re-loading the
SPL from the boot media.

This does sometimes lead to problems where the software left
the boot media in inconsistent state before warm-reset, and
because the BootROM does not reset the boot media, the boot
media is left in this inconsistent state, often until another
component attempts to access the boot media and fails with an
difficult to debug failure. To mitigate this problem, the SPL
on Altera SoCFPGA always resets all the IPs on the SoC early
on boot.

This results in a couple of register values, pre-programmed by
the BootROM, to be lost during this reset. To restore correct
operation of the IP on SoCFPGA, these values must be programmed
back into the controller by the driver. Note that on other SoCs
which do not use the HW-controlled bootstrap, more registers
may have to be programmed.

This also aligns the SPL behavior with the full Denali NAND
driver, which sets these values in denali_hw_init().

cb56caacf8 mtd: spi-nor-core: Fix static checker warnings
Static checker warns 'ret' variable may be used uninitialized in
spi_nor_erase() and spi_nor_write() in case of zero length requests.
Fix these warnings by checking for zero length requests and returning
early.

a11c081da3 mtd: spi: spi-nor-core: Add SST vendor specific SFDP parser
JESD216 allow vendors to define their own SFDP tables.

Add SST SFDP parser. The vendor table is allocated using resource-managed
kmalloc - the table will be freed on driver detach. It will be accessible
by getting the UCLASS_SPI_FLASH's private data.

The SST's SFDP table is particularly of interest because contains
pre-programmed globally unique EUI-48 and EUI-64 identifiers.

4806fcea1a mtd: spi: Export spi_flash_std_probe()
With of-platdata we need to create drivers for particular chips, or at
least drivers that are separate from the standard code, since C structures
are created by dtoc which are private to that driver.

To avoid duplicating the probing code, export this probe function for use
by these drivers.

fb4384490d mtd: Makefile: deep cleanup
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.

eb446ef625 cmd: nand/sf: isolate legacy code
The 'sf' command is not supposed to rely on the MTD stack, but both
'sf' and 'nand' commands use helpers located in mtd_uboot.c. Despite
their location, these functions do not depend at all on the MTD
stack.

This file (drivers/mtd/mtd_uboot.c) is only compiled if CONFIG_MTD is
selected, which is inconsistent with the current situation. Solve this
by moving these three functions (which are only used by the above two
commands) out of mtd_uboot.c and put them in a C file only compiled
with cmd/sf.c and cmd/nand.c.

85f7e9d547 mtd: spi: SPI_FLASH_MTD depends on MTD
It is already the case that all defconfigs with SPI_FLASH_MTD also
declare using MTD, but let's make this consistent and enforce it in
Kconfig. Most of the time SPI_FLASH_MTD is used in conjunction with
UBI, which already depends on MTD.

Because of the include's game, when some files are compiled for a SPI

GCC complains. Fix these warning by including <common.h>.
