b59cc516a1 xtensa: Remove arch_setup_bdinfo()
arch_setup_bdinfo() only configures the deprecated bi_memstart &
bi_memsize values, which should not be needed any more. Lets remove
this file completely.

e207f2256f global: Move from bi_memstart/memsize -> gd->ram_base/ram_size
With the planned removal of bi_memstart & bi_memsize, this patch now
moves the references to the better suiting gd->ram_base/ram_size

a4aa188948 board_f: Factor out bdinfo bi_mem{start, size} to setup_bdinfo
Move all assignments to gd->bd->bi_mem{start,size} to generic code in
setup_bdinfo.

Xtensa architecture is special in this regard as it defines its own
handling of gd->bd->bi_mem{start,size} fields. In order to avoid defining
a weak SDRAM function, let arch_setup_bdinfo overwrite the generic flags.

For ARC architecture, remove ARCH_EARLY_INIT_R from Kconfig since it is
not needed anymore.

Also, use gd->ram_base to populate bi_memstart to avoid an ifdef.

faf002c0ab Remove CROSS_COMPILE default from arch/*/config.mk
In order to support the compiler providing information used within
Kconfig itself we cannot have the compiler be determined by
arch/*/config.mk as we will not be able to evaluate that yet.  Given
that most documentation tells people to specify CROSS_COMPILE, remove
these references.

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.

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.

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>.
