Merge branch '2022-09-29-dm-core-support-multiple-device-trees-in-ofnode' into next
To quote the author:
At present the ofnode interface is somewhat limited, in that it cannot
access the device tree provided by the OS, only the one used by U-Boot
itself (assuming these are separate). This prevents using ofnode functions
to handle device tree fixups, i.e. ft_board_setup() and the like.
The ofnode interface was introduced to allow a consistent API to access
the device tree, whether a flat tree or a live tree (OF_LIVE) is in use.
With the flat tree, adding nodes and properties at the start of the tree
(as often happens when writing to the /chosen node) requires copying a
lot of data for each operation. With live tree, such operations are
quite a bit faster, since there is no memory copying required. This has to
be weighed against the required memory allocation with OF_LIVE, as well
as the cost of unflattening and flattening the device tree which U-Boot
is running.
This series enables support for access to multiple device trees with the
ofnode interface. This is already available to some extent with OF_LIVE,
but some of the ofnode functions need changes to allow the tree to be
specified.
The mechanism works by using the top 1-4 bits of the device tree offset.
The sign bit is not affected, since negative values must be supported.
With this implemented, it becomes possible to use the ofnode interface
to do device tree fixups. The only current user is the EVT_FT_FIXUP
event.
This has two main benefits:
- ofnode can now be used everywhere, in preference to the libfdt calls
- live tree can eventually be used everywhere, with potential speed
improvements when larger number of fixups are used
This series is only a step along the way. Firstly, while it is possible
to access the 'fix-up' tree using OF_LIVE, most of the fixup functions use
flat tree directly, rather than the ofnode interface. These need to be
updated. Also the tree must be flattened again before it is passed to the
OS. This is not currently implemented.
With OFNODE_MULTI_TREE disabled this has almost no effect on code size:
around 4 bytes if EVENT is enabled, 0 if not. With the feature enabled,
the increase is around 700 bytes, e.g. on venice2:
$ buildman -b ofn2a venice2 -sS --step 0

01: image: Drop some other #ifdefs in image-board.c
arm: w+ venice2
48: wip
arm: (for 1/1 boards) all +668.0 text +668.0
This size increase is not too bad, considering the extra functionality,
but is too large to enable everywhere. So for now this features needs to
be opt-in only, based on EVENT.

dm: core: Add the ofnode multi-tree implementation
Add the logic to redirect requests for the device tree through a function
which can look up the tree ID. This works by using the top bits of
ofnode.of_offset to encode a tree.
It is assumed that there will only be a few device trees used at runtime,
typically the control FDT (always tree ID 0) and possibly a separate FDT
to be passed the OS.
The maximum number of device trees supported at runtime is 8, with this
implementation. That would use bits 30:28 of the node-offset value,
meaning that the positive offset range is limited to bits 27:0, versus
30:1 with this feature disabled. That still allows a device tree of up
to 256MB, which should be enough for most FITs. Larger ones can be
supported by using external data with the FIT, or by enabling OF_LIVE.
Update the documentation a little and fix up the comment for
ofnode_valid().

At present, unless OF_LIVE is enabled, ofnode only supports access to one

test: Make a copy of the device tree before running a test
When the flat device tree changes it can mess up the live tree since that
uses the flat tree for its strings. This affects only a few sandbox tests

for writing improves.
While the control FDT is not intended to change while U-Boot is running,
some tests do so. For example, the ofnode interface only supports
modifying properties in the control FDT, so tests must use that.
To solve this problem, keep a copy of the FDT and restore it as needed
when the test is finished. The copy only happens on sandbox (except SPL
builds), to reduce memory usage and because these tests are not useful on
other boards. For other boards, a checksum is taken to ensure that nothing
changes.
It would be possible to always checksum the FDT on sandbox and only
restore it if needed, but this is slightly slower than restoring it every
time, at least with crc8.

board: ti: common: board_detect: Fix EEPROM read quirk for AM6 style data
The situation is similar to commit
bf6376642fe8 ("board: ti: common:
board_detect: Fix EEPROM read quirk"). This is seen on a variant of
eeproms seen on some BeagleBone-AI64 which now has a mix of both 1 byte
addressing and 2 byte addressing eeproms.
Unlike the am335x (ti_i2c_eeprom_am_get) and dra7
(ti_i2c_eeprom_dra7_get) which use constant data structure which allows
us to do a complete read of the data, the
am6(ti_i2c_eeprom_am6_get) eeprom parse operation is dynamic.
This removes the option of being able to read the complete eeprom data
in one single shot.
Fortunately, on the I2C bus, we do see the following behavior: In 1
byte mode, if we attempt to read the first header data yet again, the
misbehaving 2 byte addressing device acts in constant addressing mode
which results in the header not matching up and follow on attempt at 2
byte addressing scheme grabs the correct data.
This costs us an extra ~3 milliseconds, which is a minor penalty
compared to the consistent image support we need to have.

vexpress64: also consider DTB pointer in x1
Commit
c0fce929564f("vexpress64: fvp: enable OF_CONTROL") added code to
consider a potential DTB address being passed in the x0 register, or
revert to the built-in DTB otherwise.
The former case was used when using the boot-wrapper, to which we sell
U-Boot as a Linux kernel. The latter was meant for TF-A, for which we
couldn't find an easy way to use the DTB it uses itself. We have some
quirk to filter for a valid DTB, as TF-A happens to pass a pointer to
some special devicetree blob in x0 as well.
Now the TF-A case is broken, when enabling proper emulation of secure
memory (-C bp.secure_memory=1). TF-A carves out some memory at the top
of the first DRAM bank for its own purposes, and configures the
TrustZone DRAM controller to make this region secure-only. U-Boot will
then hang when it tries to relocate itself exactly to the end of DRAM.
TF-A announces this by carving out that region of the /memory node, in
the DT it passes on to BL33 in x1, but we miss that so far.
Instead of repeating this carveout in our DT copy, let's try to look for
a DTB at the address x1 points to as well. This will let U-Boot pick up
the DTB provided by TF-A, which has the correct carveout in place,
avoiding the hang.
While we are at it, make the detection more robust: the length test (is
the DT larger than 256 bytes?) is too fragile, in fact the TF-A port for
a new FVP model already exceeds this. So we test x1 first, consider 0
an invalid address, and also require a /memory node to detect a valid DTB.
And for the records:
Some asking around revealed what is really going on with TF-A and that
ominous DTB pointer in x0: TF-A expects EDK-2 as its non-secure payload
(BL33), and there apparently was some long-standing ad-hoc boot protocol
defined just between the two: x0 would carry the MPIDR register value of
the boot CPU, and the hardware DTB address would be stored in x1.
Now the MPIDR of CPU 0 is typically 0, plus bit 31 set, which is defined
as RES1 in the ARMv7 and ARMv8 architectures. This gives 0x80000000,
which is the same value as the address of the beginning of DRAM (2GB).
And coincidentally TF-A put some DTB structure exactly there, for its
own purposes (passing it between stages). So U-Boot was trying to use
this DTB, which requires the quirk to check for its validity.

WATCHDOG_RESET() in the loops where we wait for the bootdelay to
elapse.
This is done implicitly in the !AUTOBOOT_KEYED case,
i.e. abortboot_single_key(), because that loop contains a
udelay(10000), and udelay() does a WATCHDOG_RESET().
To fix this, simply add similar udelay() calls in the other loops.

watchdog: max6370: use __udelay() to avoid recursion
The udelay() function in lib/time.c contains a WATCHDOG_RESET()
call. So use __udelay() in max6370_wdt.c to prevent recursion.

watchdog: gpio_wdt: use __udelay() to avoid recursion
The udelay() function in lib/time.c contains a WATCHDOG_RESET()
call. The only reason this doesn't lead to a catastrophic infinite
recursion is due to the rate-limiting in wdt-uclass.c:
if (time_after_eq(now, priv->next_reset)) {
priv->next_reset = now + priv->reset_period;
wdt_reset(dev);
}
But this would fall apart if ->next_reset was updated after calling the
device's reset method.
This is needlessly fragile, and it's easy enough to avoid that
recursion in the first place by just using __udelay() directly.

configs: increase SYS_MALLOC_F_LEN for STM32 MCU's board
Some STM32 MCU's board need their SYS_MALLOC_F_LEN value enlarged
to avoid the "alloc space exhausted" error message during their boot
process.
Use the default SYS_MALLOC_F_LEN value which is set to 0x2000 in
Kconfig.
