4d49ce1bde rockchip: fix boot from non-MMC devices
Booting from non-MMC devices on Rockchip targets without this
change results in a boot failure:

Model: FriendlyElec NanoPi R5S
Net:   eth0: ethernet@fe2a0000
Hit any key to stop autoboot:  0
** Booting bootflow 'nvme#0.blk#1.bootdev.part_1' with script
** No partition table - mmc 0 **
** No partition table - mmc 0 **
Couldn't find partition mmc 0:1
Can't set block device
Wrong Image Type for bootm command
ERROR -91: Protocol wrong type for socket: can't get kernel image!
Boot failed (err=1)

This change fixes the default boot script for Rockchip targets to
support booting from non-MMC devices such as NVMe or USB drives.

Some targets with only a boot rom (e.g. NanoPi R5S) may require u-boot
to be installed on the eMMC or a MicroSD card in order to boot from
non-MMC devices.

c2d194a34e kernel: enable (ARM|ARM64)_MODULE_PLTS in generic config
This allows loading modules with large memory requirements, recently needed
while testing on armvirt/32. Past forum discussions [1] and bug reports [2]
also raised this and the ipq806x target already set it in response [3].
Given this increases kernel image size by only ~1KB, is generally useful on
multi-platform kernels, and enabled by default on upstream arm32 Linux, add
it to the generic config.

The setting has similar utility on arm64, is a requirement for KASLR, and
already enabled on most OpenWrt aarch64 targets, so pull this into the
top-level generic config.

3d66f55161 kernel: improve handling of CONFIG_IO_URING
Kernel setting CONFIG_IO_URING supports high-performance I/O for file
access and servers, generally for more performant platforms, and adds
~45 KB to kernel sizes. The need for this on less "beefy" devices is
questionable, as is the size cost considering many platforms have kernel
size limits which require tricky repartitioning if outgrown. The size
cost is also large relative to the ~180 KB bump expected between major
OpenWRT kernel releases.

No OpenWrt packages have hard dependencies on this; samba4 and mariadb
can take advantage if available (+KERNEL_IO_URING:liburing) but
otherwise build and work fine.

Since CONFIG_IO_URING is already managed via the KERNEL_IO_URING setting
in Config-kernel.in (default Y), remove it from those target configs
which unconditionally enable it, and update the defaults to enable it
conditionally only on more powerful 64-bit x86 and arm devices. It may
still be manually enabled as needed for high-performance custom builds.

7815c55f7d kernel: Deactivate CONFIG_COMPAT
This deactivates the CONFIG_COMPAT kernel option.
With CONFIG_COMPAT the kernel will provide syscall interfaces for arm32
binaries in addition to the interfaces needed for arm64 binaries.

In OpenWrt the complete userspace is compiled for this specific
architecture and support for 32 bit ARM applications is not needed.
This reduces the size and the attack surface for the systems.

On all other targets CONFIG_COMPAT is already deactivated.

adds additional checks in the copy_from_user() and copy_to_user()
functions.

This was not activated for ARCHS38 before because of a bug in the Linux
kernel 5.4 till 5.14, which as fixed and is described here:
https://github.com/foss-for-synopsys-dwc-arc-processors/linux/issues/15

I do not know why this was deactivated for mt7629 and rockchip.

c7d3bbb909 sunxi: ensure NanoPi R1 has unique MAC address
Ensure the MAC address for all NanoPi R1 boards is assigned uniquely for
each board.

The vendor ships the device in two variants; one with and one without
eMMC; but both without static mac-addresses.
In order to assign both board types unique MAC addresses, fall back on
the same method used for the NanoPi R2S and R4S in case the EEPROM
chip is not present by generating the board MAC from the SD card CID.

kernel: disable CONFIG_CPU_LITTLE_ENDIAN in generic config
Endianness depends on CPU architecture. CONFIG_CPU_(BIG/LITTLE)_ENDIAN should
be enabled on target or subtarget based on SoC architecture.

Fixes warning:
$ make kernel_oldconfig CONFIG_TARGET=subtarget
...
.config:1008:warning: override: CPU_LITTLE_ENDIAN changes choice state
....

Summary:
- ARC - only the CONFIG_CPU_BIG_ENDIAN symbol is defined for this architeture.
  If it is disabled then the processor operates in LITTLE_ENDIAN mode (default),
- ARM32 - CONFIG_CPU_LITTLE_ENDIAN symbol available since kernel 5.19. This
  option should be enabled after OpenWRT moves to kernel 6.x. After refreshing
  the kernel, the symbol disappears,
- ARM64 - enabled CONFIG_CPU_LITTLE_ENDIAN,
- MIPS - enabled relevant symbols,
- POWERPC -  enabled CONFIG_CPU_BIG_ENDIAN,
- UML - Symbols are not defined for this architecture,
- X86 - always little endian. Symbols are not defined for this architecture.
