Networked file systems may wish to forego dentry caching altogether, so
every lookup goes over the network and stale data is avoided.
Provide a no_revalidate_d_ops helper object that does this.

Linux has a generic function for extracting i2c timings parameters from
device-associated firmware nodes. Port this function to barebox, but
have it only work on device tree nodes for now.

The semantic of reset_source_set_instance() required a separate call to
reset_source_set() (or reset_source_set_priority()) and checked right
usage only using the type. Make the set of functions a bit easier to use
by dropping reset_source_set_instance() and instead introduce a function
that can set all relevant parameters (source, priority and instance) in
one go.

As with platform device id (does someone still remember?) 0 might be a
valid id. So use -1 for "unknown" or "doesn't apply" instead of 0.
Also don't pass the instance to the device tree if negative. (This ends
up as 0xffffffff otherwise.)

libfdt can be useful for very early device tree parsing, so compile it
for barobox aswell. This is done the same way as done in the Kernel:
we put C files with the same name as in libfdt into lib/ and just
include the libfdt files from there.

This adds a function to the mtd peb API to write a file spanning
multiple blocks to a mtd device. Bad blocks are automatically skipped
and before anything is done we check if the image will fit into the
remaining space (honouring bad blocks).

This adds support for BCH16 ECC encoding. The support is mostly taken
from Linux-5.3-rc6. One major change is the different wrap mode used.
The Kernel uses wrapmode 1, which means "pass all data through the BCH
engine". Still the Kernel has to skip the OOB marker which is done by
reading all user data, then use NAND_CMD_RNDOUT to position right
behind the OOB marker and then read the ECC data. Instead of doing this
we use wrap mode 4 which allows us to bypass the OOB marker from the
BCH engine automatically. This explains
bch_wrapmode = 1, eccsize0 = 0, eccsize1 = 52 vs.
bch_wrapmode = 4, eccsize0 = 4, eccsize1 = 52

Similar to what is done in the Kernel. In the Kernel we have a struct
nand_device embedded into struct nand_chip and the nand_device has an
mtd_info embedded into it. Until we have struct nand_device we embed
mtd_info directly into the nand_chip.

All drivers in tree use mtd->priv for the nand_chip. Add and use a static
inline wrapper mtd_to_nand() which we already have in the kernel for
getting the nand_chip from the mtd_info struct. Next step would be to
embed a struct mtd_info into struct nand_chip.

This patch add elf64 loading support to the elf loader. Since
elf32 and elf64 uses completely different types, to avoid copying all
the code and simply replace elf32 with elf64, use a macro which will
return the appropriate field for each type of header. This macro
generates getter for elf structures according to the class of the loaded
elf.
All direct elf struct dereference are then replaced by call to generated
functions. This allows to keep a common loader code even if types are
different.

Trying to output a single character via
echo -a /dev/serial0-1
currently results in garbage output after the newline, because console.c's
fops_write discards the buffer length and passes the buffer to
(struct cdev)::puts which only handles NUL-terminated strings.
Fix this by amending (struct cdev)::puts with a new nbytes parameter,
which is correctly propagated. All this functions now return at most the
nbytes parameter they were passed in. This fixes __console_puts, which
used to count new lines twice in its return value.

Both STM32MP BootROM and TF-A first stage expect subsequent bootloader
stages to feature a specific 256-byte long STM32 file header.
Add detection of the header to file_detect_type().
While there's only one version of the header so far, identify the new
header as v1 anyway, so new versions can be unambiguously added.

Some architectures have non-contiguous GPIO ranges where some GPIOs can
have identifiers exceeding the hardcoded ARCH_NR_GPIOs of 256.
One such example is the STM32MP, whose gpioz controller has identifiers
that go up to ('Z' - 'A' + 1) * 0x10 - 1 = 415.
Instead of increasing the array size for all architectures or doing
some sort of packing, allow architecture to define their own overriding
CONFIG_ARCH_NR_GPIO like the kernel does.

The imx-bbu-nand-fcb update handler code calls into the NAND driver
to get the ecc strength and bad block marker position. Change the
API so that only a single function is necessary and not three functions.
Also in future the ecc strength will be configurable via device tree.
This means static parameters like page size / oob size are no longer
enough to calculate the ecc strength and so we store a pointer to our
mtd_info struct in a static global variable.

it rather than trying to guess from HAB failure events if this is

We can only do the selftest once per boot though, doing it a second time
yields an error:

This adds driver support for the 12 GPIO banks on the STM32MP157.
As they are accessible to both the Cortex-A cores as well as the Cortex-M
core, modifications to these are protected by a hardware spinlock
and clocks are enabled/disabled as required.
All register fiddling done by the driver is collected in <soc/stm32/gpio.h>,
so future PBL code may make use of it as well to chainload barebox proper.

Some STM32MP Linux drivers, which could be ported to barebox as part of
improved second stage barebox support, are using hardware spinlocks to
coordinate access between the three processors. While barebox only
uses one of the two Cortex-A cores, spin locks may still be necessary
because of firmware loaded unto the Cortex-M.
To ease porting these drivers, without having to import the hw spinlock
driver now, add stubs for the functions.
The stubs will we be reused when CONFIG_HWSPINLOCK is introduced,
but is disabled in config. The API is oriented after the implementation
in U-Boot.
