This patch adds the basic machine file for the MesonX SoCs. Only Meson6
is populated.
Signed-off-by: Carlo Caione <carlo@caione.org>
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
The Meson6 SoC is produced by Amlogic inc. and it is based on 2 Cortex
A9 and an ARM Mali-400 GPU.
This patch adds two basic DTSI for the preliminary support of Meson and
Meson6 SoCs. Another DTS is also added for supporting the atv1200 board,
produced by Geniatech inc.

The alignment fixup incorrectly decodes faulting ARM VLDn/VSTn
instructions (where the optional alignment hint is given but incorrect)
as LDR/STR, leading to register corruption. Detect these and correctly
treat them as unhandled, so that userspace gets the fault it expects.

SCTLR.HA (hardware access flag) is deprecated and not actually
implemented by any CPUs. Furthermore, it can confuse cr_alignment checks
where the whole value of SCTLR is compared against the value sitting in
the hardware, since the bit is actually RAZ/WI and will not match the
saved cr_alignment value.

With the introduction of DT based idle states, CPUidle drivers for ARM
can now initialize idle states data through properties in the device tree.
This patch adds code to the big.LITTLE CPUidle driver to dynamically
initialize idle states data through the updated device tree source file.

As discovered on a custom board similar to at91sam9263ek and basing
its devicetree on that one apparently the pin muxing doesn't get
set up properly. This was discovered since the custom boards u-boot
does funky stuff with the pin muxing and leaved it set to SPI
which made the MMC driver not work under Linux.
The fix is simply to define the given configuration as the default.
This probably worked by pure luck before, but it's better to
make the muxing explicitly set.

1. We were calling clear_flush_young_notify in unmap_one, but we are
within an mmu notifier invalidate range scope. The spte exists no more
(due to range_start) and the accessed bit info has already been
propagated (due to kvm_pfn_set_accessed). Simply call
clear_flush_young.
2. We clear_flush_young on a primary MMU PMD, but this may be mapped
as a collection of PTEs by the secondary MMU (e.g. during log-dirty).
This required expanding the interface of the clear_flush_young mmu
notifier, so a lot of code has been trivially touched.
3. In the absence of shadow_accessed_mask (e.g. EPT A bit), we emulate
the access bit by blowing the spte. This requires proper synchronizing
with MMU notifier consumers, like every other removal of spte's does.

The Exynos System-on-Chips have ~7 distinctive I2C IO ports (exact
number depends on chip). However some integrated circuits on board, also
using I2C protocol for communication, can be connected to the SoC by
other GPIO. Enabling the I2C GPIO driver allows using such additional
integrated circuits.
An example of such chip using I2C and connected over GPIO to SoC is
Maxim 77693 MUIC on Trats2 board. The regulator driver of Maxim
77693 offers charger and safeout LDO (necessary for USB OTG).

Will Deacon pointed out, that the currently used opcode for filling holes,
that is 0xe7ffffff, seems not robust enough ...
$ echo 0xffffffe7 | xxd -r > test.bin
$ arm-linux-gnueabihf-objdump -m arm -D -b binary test.bin
...
0: e7ffffff udf #65535 ; 0xffff
... while for Thumb, it ends up as ...
0: ffff e7ff vqshl.u64 q15, <illegal reg q15.5>, #63
... which is a bit fragile. The ARM specification defines some *permanently*
guaranteed undefined instruction (UDF) space, for example for ARM in ARMv7-AR,
section A5.4 and for Thumb in ARMv7-M, section A5.2.6.
Similarly, ptrace, kprobes, kgdb, bug and uprobes make use of such instruction
as well to trap. Given mentioned section from the specification, we can find
such a universe as (where 'x' denotes 'don't care'):
ARM: xxxx 0111 1111 xxxx xxxx xxxx 1111 xxxx
Thumb: 1101 1110 xxxx xxxx
We therefore should use a more robust opcode that fits both. Russell King
suggested that we can even reuse a single 32-bit word, that is, 0xe7fddef1
which will fault if executed in ARM *or* Thumb mode as done in f928d4f2a86f
("ARM: poison the vectors page"). That will still hold our requirements:
$ echo 0xf1defde7 | xxd -r > test.bin
$ arm-unknown-linux-gnueabi-objdump -m arm -D -b binary test.bin
...
0: e7fddef1 udf #56801 ; 0xdde1
$ echo 0xf1defde7f1defde7f1defde7 | xxd -r > test.bin
$ arm-unknown-linux-gnueabi-objdump -marm -Mforce-thumb -D -b binary test.bin
...
0: def1 udf #241 ; 0xf1
2: e7fd b.n 0x0
4: def1 udf #241 ; 0xf1
6: e7fd b.n 0x4
8: def1 udf #241 ; 0xf1
a: e7fd b.n 0x8
So on ARM 0xe7fddef1 conforms to the above UDF pattern, and the low 16 bit
likewise correspond to UDF in Thumb case. The 0xe7fd part is an unconditional
branch back to the UDF instruction.
