RK3128 SoCs have two i2s controllers. i2s_8ch has 8 tx and 2 rx channels
and is internally hard-wired to the hdmi-controller respectivly the SoC's
analog codec. i2s_2ch has 2 tx and 2 rx channels and can also be used
externally as it's pins are exposed though pinctrl.

In the combined DT of rk3066a/rk3188 the emac node uses as place holder
the compatible string "snps,arc-emac". The last real user nSIM_700
of the "snps,arc-emac" compatible string in a driver was removed in 2019.
Rockchip emac nodes don't make use of this common fall back string.
In order to removed unused driver code replace this string with
"rockchip,rk3066-emac".
As we are there remove the blank lines and sort.

EFI runtime services are remapped into the lower 1 GiB of virtual
address space at boot, so they are guaranteed to be able to co-exist
with the kernel virtual mappings without the need to allocate space for
them in the kernel's vmalloc region, which is rather small.
This means those mappings are covered by TTBR0 when LPAE PAN is enabled,
and so 'user' access must be enabled while such calls are in progress.

The current arm32 architecture does not yet support the
HAVE_LD_DEAD_CODE_DATA_ELIMINATION feature. arm32 is widely used in
embedded scenarios, and enabling this feature would be beneficial for
reducing the size of the kernel image.
In order to make this work, we keep the necessary tables by annotating
them with KEEP, also it requires further changes to linker script to KEEP
some tables and wildcard compiler generated sections into the right place.
When using ld.lld for linking, KEEP is not recognized within the OVERLAY
command, and Ard proposed a concise method to solve this problem.
It boots normally with defconfig, vexpress_defconfig and tinyconfig.
The size comparison of zImage is as follows:
defconfig vexpress_defconfig tinyconfig
5137712 5138024 424192 no dce
5032560 4997824 298384 dce
2.0% 2.7% 29.7% shrink
When using smaller config file, there is a significant reduction in the
size of the zImage.
We also tested this patch on a commercially available single-board
computer, and the comparison is as follows:
a15eb_config
2161384 no dce
2092240 dce
3.2% shrink
The zImage size has been reduced by approximately 3.2%, which is 70KB on
2.1M.

The frame pointer unwinder relies on a standard layout of the stack
frame, consisting of (in downward order)
Calling frame:
PC <---------+
LR |
SP |
FP |
.. locals .. |
Callee frame: |
PC |
LR |
SP |
FP ----------+
where after storing its previous value on the stack, FP is made to point
at the location of PC in the callee stack frame, using the canonical
prologue:
mov ip, sp
stmdb sp!, {fp, ip, lr, pc}
sub fp, ip, #4
The ftrace code assumes that this activation record is pushed first, and
that any stack space for locals is allocated below this. Strict
adherence to this would imply that the caller's value of SP at the time
of the function call can always be obtained by adding 4 to FP (which
points to PC in the callee frame).
However, recent versions of GCC appear to deviate from this rule, and so
the only reliable way to obtain the caller's value of SP is to read it
from the activation record. Since this involves a read from memory
rather than simple arithmetic, we need to use the uaccess API here which
protects against inadvertent data aborts resulting from attempts to
dereference bogus FP values.
The plain uaccess API is ftrace instrumented itself, so to avoid
unbounded recursion, use the __get_kernel_nofault() primitive directly.
