Tom RiniandFabio Estevam d4a9ce26cb nxp: Move FSL_SEC_MON related options to arch/Kconfig.nxp
The options related to FSL_SEC_MON are part of the chain of trust
related options and should be under that menu, so move it there.
Furthermore we don't need to prompt for the driver itself but do need to
allow for configuration of the monitor endianess.

Sam ProtsenkoandTom Rini 89911825a2 dfu: Fix dfu_config_interfaces() for single interface DFU syntax
As stated in DFU documentation [1], the device interface part might be
missing in dfu_alt_info:

    dfu_alt_info
        The DFU setting for the USB download gadget with a semicolon
        separated string of information on each alternate:
            dfu_alt_info="<alt1>;<alt2>;....;<altN>"
        When several devices are used, the format is:
            - <interface> <dev>'='alternate list (';' separated)

So in first case dfu_alt_info might look like something like this:

    dfu_alt_info="mmc 0=rawemmc raw 0 0x747c000 mmcpart 1;"

And in second case (when the interface is missing):

    dfu_alt_info="rawemmc raw 0 0x747c000 mmcpart 1;"

When the interface is not specified the 'dfu' command crashes when
called using 'dfu 0' or 'dfu list' syntax:

    => dfu list
    "Synchronous Abort" handler, esr 0x96000006, far 0x0

That's happening due to incorrect string handling in
dfu_config_interfaces(). In case when the interface is not specified in
dfu_alt_info it triggers this corner case:

    d = strsep(&s, "=");  // now d contains s, and s is NULL
    if (!d)
        break;
    a = strsep(&s, "&");  // s is already NULL, so a is NULL too
    if (!a)               // corner case
        a = s;            // a is NULL now

which causes NULL pointer dereference later in this call, due to 'a'
being NULL:

    part = skip_spaces(part);

That's because as per strsep() behavior, when delimiter ("&") is not
found, the token (a) becomes the entire string (s), and string (s)
becomes NULL. To fix that issue assign "a = d" instead of "a = s",
because at that point variable d actually contains previous s, which
should be used in this case.

Transmission of short packets does not work good for XFI (GDM2) and

 - setting of PAD_EN bit in the corresponding REG_GDM_FWD_CFG(n)

The issue should present for the lan switch (GDM1) as well, but it does

Mikhail KshevetskiyandTom Rini 997786bbf4 drivers/net/airoha_eth: fix stalling in package receiving
ARCH_DMA_MINALIGN is 64 for ARMv7a/ARMv8a architectures, but RX/TX
descriptors are 32 bytes long. So they may not be aligned on an
ARCH_DMA_MINALIGN boundary. In case of RX path, this may cause the
following problem

1) Assume that a packet has arrived and the EVEN rx descriptor has been
   updated with the incoming data. The driver will invalidate and check
   the corresponding rx descriptor.

2) Now suppose the next descriptor (ODD) has not yet completed.

   Please note that all even descriptors starts on 64-byte boundary,
   and the odd ones are NOT aligned on 64-byte boundary.

   Inspecting even descriptor, we will read the entire CPU cache line
   (64 bytes). So we read and sore in CPU cache also the next (odd)
   descriptor.

3) Now suppose the next packet (for the odd rx descriptor) arrived
   while the first packet was being processed. So we have new data
   in memory but old data in cache.

4) After packet processing (in arht_eth_free_pkt() function) we will
   cleanup the descriptor and put it back to rx queue.

   This will call flush_dcache_range() function for the even descriptor,
   so the odd one will be flushed as well (it is in the same cache line).
   So the old data will be written to the next rx descriptor.

5) We get a freeze. The next descriptor is empty (so the driver is
   waiting for packets), but the hardware will continue to receive
   packets on other available descriptors. This will continue until
   the last available rx descriptor is full. Then the hardware will
   also freeze.

The problem will be solved if the previous descriptor will be put back
to the queue instead of the current one.

If the current descriptor is even (starts on a 64-byte boundary),
then putting the previous descriptor to the rx queue will affect
the previous cache line. To be 100% ok, we must make sure that the
previous and the one before the previous descriptor cannot be used
for receiving at this moment.

If the current descriptor is odd, then the previous descriptor is on
the same cache line. Both (current and previous) descriptors are not
currently in use, so issue will not arrise.

WARNING: The following restrictions on PKTBUFSRX must be held:
  * PKTBUFSRX is even,
  * PKTBUFSRX >= 4.

The bug appears on 32-bit airoha platform, but should be present on
64-bit as well.

The code was tested both on 32-bit and 64-bit airoha boards.

Mikhail KshevetskiyandTom Rini 5d49fa9e56 drivers/net/airoha_eth: fix packet transmission errors
The dma_map_single() function calls one of the functions
  * invalidate_dcache_range(),
  * flush_dcache_range().
Both of them expect that 'vaddr' is aligned to the ARCH_DMA_MINALIGN
boundary. Unfortunately, RX/TX descriptors are 32-byte long. Thus they
might not be aligned to the ARCH_DMA_MINALIGN boundary. Data flushing
(or invalidating) might do nothing in this case.

The same applies to dma_unmap_single() function.

In the TX path case the issue might prevent package transmission (filled
TX descriptor was not flushed).

To fix an issue a special wrappers for
  * dma_map_single(),
  * dma_unmap_single()
functions were created. The patch fix flushing/invalidatiog for the
RX path as well.

The bug appears on 32-bit airoha platform, but should be present on
64-bit as well.

The code was tested both on 32-bit and 64-bit airoha boards.

In the Fixes commit, I initialized size_inc from the return value of
the new fit_estimate_hash_sig_size() helper. That helper may fail and
report that by returning a negative value, but I overlooked that
size_inc had type size_t, and hence the error check doesn't work.

Change size_inc to have type int so the error check works.  Inside the
loop, it is passed to another function as a size_t parameter, but
that's fine, because we know it is non-negative, and its value may be
incremented in steps of 1024 and is capped at ~64K, so it will
certainly never overflow an int.

- Standard C types, char, short, ...
- Kernel-style fixed-width types s8, u64, ...
- POSIX/C99 fixed-width types int16_t, uint32_t, ...

Please note that a naive approach like spelling out the full decimal
value for the constants doesn't really work, as there is no such thing
as a "negative integer constant". That is, doing

#define LLONG_MIN -9223372036854775808LL

would lead to the compiler complaining

  warning: integer constant is so large that it is unsigned

and the type of that LLONG_MIN would actually be "unsigned long long", so e.g.

#if LLONG_MIN >= 0
#warning "LLONG_MIN is not negative?"
#endif

would fire.

Rasmus VillemoesandTom Rini dd260d95fd limits.h: provide all limit macros for standard [u]intNN_t types
Currently, we only have UINT32_MAX and UINT64_MAX in limits.h, and
then stdint.h and kernel.h somewhat randomly define UINT8_MAX and
INT32_MAX, respectively.

Provide a full set of definitions in terms of the min/max macros for
the types that [u]intNN_t are defined in terms of, namely the {s,u}NN
ones.

Try to avoid breaking whatever depended on getting UINT8_MAX from our
compat stdint.h by replacing it with an include of limits.h.

Rasmus VillemoesandTom Rini 0604595c16 move limits for sNN/uNN types from kernel.h to limits.h
Since we define the {s,u}{8,16,32,64} types the same way on all
architectures, i.e. everybody uses asm-generic/int-ll64.h, we can just
define the associated limit macros in terms of those for the
corresponding types. This eliminates another set of limit macros that
are not usable in #if conditionals.

These type names and macros are not C or POSIX, so there's no language
violation, but certainly a violation of developers' reasonable
expectations.

Rasmus VillemoesandTom Rini dc323f3bee move more limits from kernel.h to limits.h and standardize their definitions
In a customer project that was building a stand-alone application, I
hit a problem related to the fact that our LONG_MAX and friends are
not standards-compliant, in that they are not "suitable for use in #if
preprocessing directives"

... /toolchain_none/arm-cortexa8-eabi/sys-include/machine/_default_types.h:25:31: error: missing binary operator before token "long"
   25 |   || ( defined(LLONG_MAX) && (LLONG_MAX > 0x7fffffff) )
      |                               ^~~~~~~~~

So following up on commit 13de848338 ("mbedtls: add mbedtls into the
build system"), move the rest of the macros associated to the standard
C types {signed,unsigned} {char, short, int, long, long long} (and of
course bare 'char') to limits.h.

Make use of the fact that both gcc and clang provide suitable
predefined __FOO_MAX__ macros for the signed types, and use a standard
scheme for defining the FOO_MIN and UFOO_MAX macros in terms of
FOO_MAX.

Note that suffixes like L and ULL are allowed for preprocessor
integers; it is (casts) which are not. And using appropriate suffixes,
we can arrange for the type of e.g. UINT_MAX to be "unsigned int" due
to integer promotion rules.

Balaji SelvanathanandCasey Connolly 9cd3118e4a watchdog: qcom-wdt: Drop read check on write-only WDT_EN register
On some Qualcomm platforms, such as Dragonwing boards, the WDT_EN
register is write-only. Reading it back after enabling the watchdog
can return invalid data or cause unexpected behavior.

In particular, the check:
  if (readl(wdt_addr(wdt, WDT_EN)) != 1)
may fail even though the watchdog is correctly enabled and running.
This leads to misleading error messages and unnecessary failures.

Removing the read check ensures compatibility and avoids false
negatives on platforms where WDT_EN is not readable.

This work builds upon this previous submission:
