commit 83a1cde5c74bfb44b49cb2a940d044bb2380f4ea upstream.
With newer versions of GCC, there is a panic in da850_evm_config_emac()
when booting multi_v5_defconfig in QEMU under the palmetto-bmc machine:
Unable to handle kernel NULL pointer dereference at virtual address 00000020
pgd = (ptrval)
[00000020] *pgd=00000000
Internal error: Oops: 5 [#1] PREEMPT ARM
Modules linked in:
CPU: 0 PID: 1 Comm: swapper Not tainted 5.15.0 #1
Hardware name: Generic DT based system
PC is at da850_evm_config_emac+0x1c/0x120
LR is at do_one_initcall+0x50/0x1e0
The emac_pdata pointer in soc_info is NULL because davinci_soc_info only
gets populated on davinci machines but da850_evm_config_emac() is called
on all machines via device_initcall().
Move the rmii_en assignment below the machine check so that it is only
dereferenced when running on a supported SoC.

commit 8b2360c7157b462c4870d447d1e65d30ef31f9aa upstream.
__setup() handlers should return 1 to obsolete_checksetup() in
init/main.c to indicate that the boot option has been handled.
A return of 0 causes the boot option/value to be listed as an Unknown
kernel parameter and added to init's (limited) argument or environment
strings. Also, error return codes don't mean anything to
obsolete_checksetup() -- only non-zero (usually 1) or zero.
So return 1 from jive_mtdset().

commit 9d67412f24cc3a2c05f35f7c856addb07a2960ce upstream.
iop32x is one of the last platforms to use IRQ 0, and this has apparently
stopped working in a 2014 cleanup without anyone noticing. This interrupt
is used for the DMA engine, so most likely this has not actually worked
in the past 7 years, but it's also not essential for using this board.
I'm splitting out this change from my GENERIC_IRQ_MULTI_HANDLER
conversion so it can be backported if anyone cares.

Tweak the ftrace return paths to avoid redundant loads of SP, as well as

This also fixes the inconsistency of using MOV to perform a function

importantly, does not perform an interworking return, unlike compiler
generated function returns in Thumb2 builds.

If clocksource is back to 32k_counter, timer12 is now the clockevent
source (as before) and timer2 is not longer needed here.
This commit fixes the same issue observed with commit 23885389dbbb
("ARM: dts: Fix timer regression for beagleboard revision c") when sleep
is blocked until hitting keys over serial console.

commit 7b83299e5b9385943a857d59e15cba270df20d7e upstream.
early_param() handlers should return 0 on success.
__setup() handlers should return 1 on success, i.e., the parameter
has been handled. A return of 0 would cause the "option=value" string
to be added to init's environment strings, polluting it.

commit d920eaa4c4559f59be7b4c2d26fa0a2e1aaa3da9 upstream.
The kgdb code needs to register an undef hook for the Thumb UDF
instruction that will fault in order to be functional on Thumb2
platforms.

The correct property name is 'assigned-clock-parents', not
'assigned-clocks-parents'. Though if the platform works with the typo, one
has to wonder if the property is even needed.

The dt-bindings for the UART controller only allow the following values
for Meson8 SoCs:
- "amlogic,meson8b-uart", "amlogic,meson-ao-uart"
- "amlogic,meson8b-uart"
Use the correct fallback compatible string "amlogic,meson-ao-uart" for
AO UART. Drop the "amlogic,meson-uart" compatible string from the EE
domain UART controllers.
Also update the order of the clocks to match the order defined in the
yaml bindings.
