ba03a6c944 spi: atmel-quadspi: fix possible MMIO window size overrun
The sama5d2 QSPI controller memory space is limited to 128MB:
0x9000_00000-0x9800_00000/0XD000_0000--0XD800_0000.

There are nor flashes that are bigger in size than the memory size
supported by the controller: Micron MT25QL02G (256 MB).

Check if the address exceeds the MMIO window size. An improvement
would be to add support for regular SPI mode and fall back to it
when the flash memories overrun the controller's memory space.

Unfortunately this restarts U-Boot multiple times which adds about a

Changing test_vboot into a class causes it not to be discovered and makes

7dbafe0634 Merge tag 'arc-last-minute-fixes-for-2020.04' of https://gitlab.denx.de/u-boot/custodians/u-boot-arc
This last minute pull-request is intended to fix some drivers
when used on ARC boards. The problem was introduced by
07906b3dad

What happened while doing one pretty simple improvement to make
U-Boot port more flexible and portable (by switching accessors from
assembly-written to plain C version) we implicitly added 2 problems:

 1. Downgraded accessors from being volatile which signalled to
    the compiler that it's now possible to do all kinds of optimizations
    which may easily include merge of subsequent byte reads/writes into
    word operations. Which is OK for accessing mormal memory but
    breaks operation of peripherals if we access its memory-mapped regs
    in such a "creative" manner.
 2. As a part of assembly-written implementation we had compiler barriers
    in form of the following construction 'asm volatile("" : : : "memory")',
    and we dropped it in C implemntation. This in its turn enabled compiler
    to mess with instruction ordering. Guess what it gives us in the end :)

So with all that we had in some corner-cases veeery funny instruction flows
generated. And in particular it broke DW SPI functionality when we were
writing large amount of data. Funny enough our tests which were writing
small amount of data still worked and only by the chance we caught that
breakage and unrolled that quite interesting loop of unexpected
problems.

The road to hell is paved with good intentions. Amen :)

45bd649511 ARC: IO: add MB for __raw_* memory accessors
We add memory barriers for __raw_readX / __raw_writeX accessors same
way as it is done for readX and writeX accessors as lots of U-boot
driver uses __raw_readX / __raw_writeX instead of proper accessor
with barrier.

It will save us from lot's of debugging in the future and it is OK
as U-Boot is not that performance oriented as real run-time
software like OS or user bare-metal app so we may afford being not
super fast as we only being executed once.

391c40048b mpc8xxx_spi: always use 8-bit characters, don't read or write garbage
There are a few problems with the current driver.

First, it unconditionally reads from dout/writes to din whether or not
those pointers are NULL. So for example a simple "sf probe" ends up
writing four bytes at address 0:

=> md.l 0x0 8
00000000: 45454545 45454545 05050505 05050505    EEEEEEEE........
00000010: 00000000 00000000 07070707 07070707    ................
=> sf probe 0
mpc8xxx_spi_xfer: slave spi@7000:0 dout 0FB53618 din 00000000 bitlen 8
mpc8xxx_spi_xfer: slave spi@7000:0 dout 00000000 din 0FB536B8 bitlen 48
SF: Detected s25sl032p with page size 256 Bytes, erase size 64 KiB, total 4 MiB
=> md.l 0x0 8
00000000: ff000000 45454545 05050505 05050505    ....EEEE........
00000010: 00000000 00000000 07070707 07070707    ................

(here I've change the first debug statement to a printf, and made it
print the din/dout pointers rather than the uints they point at).

Second, as we can also see above, it always writes a full 32 bits,
even if a smaller amount was requested. So for example

=> mw.l $loadaddr 0xaabbccdd 8
=> md.l $loadaddr 8
02000000: aabbccdd aabbccdd aabbccdd aabbccdd    ................
02000010: aabbccdd aabbccdd aabbccdd aabbccdd    ................

Fix all of that by always using a character size of 8, and reject
transfers that are not a whole number of bytes. While it ends being
more work for the CPU, we're mostly bounded by the speed of the SPI
bus, and we avoid writing to the mode register in every loop.

1a7b462dee mpc8xxx_spi: put max_cs to use
Currently, max_cs is write-only; it's just set in
mpc8xxx_spi_ofdata_to_platdata and not otherwise used.

My mpc8309 was always resetting during an "sf probe 0". It turns out
dm_gpio_set_dir_flags() was being called with garbage, since nothing
had initialized priv->gpios[0] - our device tree used "cs-gpios"
rather than "gpios", so gpio_request_list_by_name() had returned 0.

That would have been a lot easier to figure out if the chip select
index was sanity checked, so rename max_cs to cs_count, and reject a
xfer with a too large cs index.

3fb22bc2f8 gpio/mpc83xx_spisel_boot.c: gpio driver for SPISEL_BOOT signal
Some SoCs in the mpc83xx family, e.g. mpc8309, have a dedicated spi
chip select, SPISEL_BOOT, that is used by the boot code to boot from
flash.

This chip select will typically be used to select a SPI boot
flash. The SPISEL_BOOT signal is controlled by a single bit in the
SPI_CS register.

Implement a gpio driver for the spi chip select register. This allows a
spi driver capable of using gpios as chip select, to bind a chip select
to SPISEL_BOOT.

It may be a little odd to do this as a GPIO driver, since the signal
is neither GP or I, but it is quite convenient to present it to the
spi driver that way. The alternative it to teach mpc8xxx_spi to handle
the SPISEL_BOOT signal itself (that is how it's done in the linux
kernel, see commit 69b921acae8a)

dd4cf53f98 gpio: mpc8xxx: don't do RMW on gpdat register when setting value
The driver correctly handles reading back the value of an output gpio
by reading from the shadow register for output, and from gpdat for
inputs.

Unfortunately, when setting the value of some gpio, we do a RMW cycle
on the gpdat register without taking the shadow register into account,
thus accidentally setting other output gpios (at least those whose
value cannot be read back) to 0 at the same time.

When changing a gpio from input to output, we still need to make sure
it initially has the requested value. So, the procedure is

- update the shadow register
- compute the new gpdir register
- write the bitwise and of the shadow and new gpdir register to gpdat
- write the new gpdir register

1d7ad9fa05 gpio: mpc8xxx: don't modify gpdat when setting gpio as input
Since some chips don't support reading back the value of output gpios
from the gpdat register, we should not do a RMW cycle (i.e., the
clrbits_be32) on the gpdat register when setting a gpio as input, as
that might accidentally change the value of some other (still
configured as output) gpio.

The extra indirection through mpc8xxx_gpio_set_in() does not help
readability, so just fold the gpdir update into
mpc8xxx_gpio_direction_input().

When running in debugger without bootrom, r0 to r3 are random values.
So, skip save the value when r0 is not bootrom shared data address.
