Kernel has added the different variants of the Rock Pi 4 in commit
b5edb0467370 ("arm64: dts: rockchip: Mark rock-pi-4 as rock-pi-4a
dts"). The former Rock Pi 4 is now Rock Pi 4A.
For compatibility with kernel 5.4, this rename has been held back
so far. Having switched to kernel 5.10 now, we can finally apply
it in our tree as well.

The rockchip platform supports squashfs SD card images. However, the
resulting image is not padded to completely fill the rootfs partition.
Because of that, the f2fs overlay might not be erased, resulting in
uci-defaults not bing executed or the configuration not being erased,
even though drop config was selected.
Modify the image generation process so the image is padded to cover the
entire root filesystem partition.

The default value for CONFIG_RCU_CPU_STALL_TIMEOUT was changed from 60
seconds to 21 seconds in 2012 in the upstream kernel. Some targets
already use 21 seconds.
This patch changes the default value in the generic configuration to 21
seconds and removes the target specific configuration options.

CONFIG_RCU_{NEED_SEGCBLIST,STALL_COMMON} are set basically everywhere. Move them
to the generic kconfigs. And resort the generic kconfigs while at it.

Based on the existing documentation [1][2], I dare anyone to demonstrate that
we need to fine-tune these RCU parameters. The (performance) breakage potential
for doing so is immense, so let's just please put down this loaded footgun.
Disable CONFIG_RCU_EXPERT and its dependent symbols. Additionally, remove the
CONFIG_RCU_EXPERT symbol from the target kconfigs which contain it.

Do not deactivate the kernel configuration symbol CONFIG_STAGING in the
target configurations any more. This prevented the build of the exfat.ko
for example.

On the NanoPI R4S it takes an average of 3..5 seconds for the network devices
to appear in '/proc/interrupts'.
Wait up to 10 seconds to ensure that the distribution of the interrupts
really happens.
