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.

c0a5a81f74 asm: dma-mapping.h: Fix dma mapping functions
Subsystems such as USB expect dma_map_single() and dma_unmap_single() to
do dcache flush/invalidate operations as required. For example, see
see drivers/usb/gadget/udc/udc-core.c::usb_gadget_map_request().
Currently drivers do this locally, (see drivers/usb/dwc3/ep0.c,
drivers/mtd/nand/raw/denali.c etc..)
Update arch specific dma_map_single() and dma_unmap_single() APIs to do
cache flush/invalidate  operations, so that drivers need not implement
them locally.

db41d65a97 common: Move hang() to the same header as panic()
At present panic() is in the vsprintf.h header file. That does not seem
like an obvious choice for hang(), even though it relates to panic(). So

c30b7adbca common: Move interrupt functions into a new header
These functions do not use driver model but are fairly widely used in
U-Boot. But it is not clear that they will use driver model anytime soon,
so we don't want to label them as 'legacy'.

Move them to a new irq_func.h header file. Avoid the name 'irq.h' since it
is widely used in U-Boot already.

a0aba8a2eb CONFIG_SYS_[DI]CACHE_OFF: convert to Kconfig
CONFIG_SYS_[DI]CACHE_OFF had been partially converted to Kconfig
parameters; only for the ARC architecture. This patch turns these two
parameters into Kconfig items everywhere else they are found.

All of the include/configs/* and defconfig changes in this patch are
for arm machines only. The Kconfig changes for arc, nds32, riscv,
and xtensa have been included since these symbols are found in code
under arch/{arc,nds32,riscv,xtensa}, however, no currently-defined
include/configs/* or defconfigs for these architectures exist which
include these symbols.

These results have been confirmed with tools/moveconfig.py.

b7b4af0e35 CONFIG_SYS_[ID]CACHE_OFF: unify the 'any' case
According to De Morgan's Law[1]:
	!(A && B) = !A || !B
	!(A || B) = !A && !B

There are 5 places in the code where we find:
	#if !(defined(CONFIG_SYS_ICACHE_OFF) && defined(CONFIG_SYS_DCACHE_OFF))
and 4 places in the code where we find:
	#if (!defined(CONFIG_SYS_ICACHE_OFF) || !defined(CONFIG_SYS_DCACHE_OFF))

In words, the construct:
	!defined(CONFIG_SYS_[DI]CACHE_OFF)
means:
	"is the [DI]CACHE on?"
and the construct:
	defined(CONFIG_SYS_[DI]CACHE_OFF)
means:
	"is the [DI]CACHE off?"

Therefore
	!(defined(CONFIG_SYS_ICACHE_OFF) && defined(CONFIG_SYS_DCACHE_OFF))
means:
	"the opposite of 'are they both off?'"
in other words:
	"are either or both on?"
and:
	(!defined(CONFIG_SYS_ICACHE_OFF) || !defined(CONFIG_SYS_DCACHE_OFF)
means:
	"are either or both on?"

As a result, I've converted the 4 instances of '(!A || !B)' to '!(A && B)' for
consistency.

ffd4c7c2ec dts: switch spi-flash to jedec, spi-nor compatible
There is no reason not to use the Linux "jedec,spi-nor" binding in U-Boot
dts files. This compatible has been added in sf_probe, let use it.

This patch switches to jedec,spi-nor when spi-flash is used in the DTS
and DTSI files, and removed spi-flash when jedec,spi-nor is already
present.

The x86 dts are switched in a separate commit since it depends on a change

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.

01abae4d04 Remove various unused interrupt related code
With d53ecad92f some unused interrupt related code was removed.
However all of these options are currently unused.  Rather than migrate
some of these options to Kconfig we just remove the code in question.

The only related code changes here are that in some cases we use
CONFIG_STACKSIZE in non-IRQ related context.  In these cases we rename
and move the value local to the code in question.

Fixes: d53ecad92f ("Merge branch 'master' of git://git.denx.de/u-boot-sunxi")

4491327d59 Remove arch/${ARCH}/include/asm/errno.h
Unlike Linux, nothing about errno.h is arch-specific in U-Boot.
As you see, all of arch/${ARCH}/include/asm/errno.h is just a
wrapper of <asm-generic/errno.h>.  Actually, U-Boot does not
export headers to user-space, so we just have to care about the
consistency in the U-Boot tree.

Now all of include directives for <asm/errno.h> are gone.
Deprecate <asm/errno.h>.
