imx8mn-venice-u-boot: Fix broken boot

constantly reboot. Fix this by adding the spba node to the spl

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.

Currently, AUTOBOOT_KEYED and its variant AUTOBOOT_ENCRYPTION are
broken when one has an external always-running watchdog device with a
timeout shorter than the configured boot delay (in my case, I have a
gpio-wdt one with a timeout of 1 second), because we fail to call
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: 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.

cmd: fdt: Add support for reading stringlist property values
The fdt command currently handles stringlists as strings in 'fdt get value'
subcommand. Since strings in FDT stringlists are separated by '\0', only
the first value gets inserted into the environment variable passed to the
'fdt get value' command.
Example, consider the following DT snippet:
/ { compatible = "foo", "bar" };
The following command only reports the first string in stringlist:
=> fdt get value var / compatible ; print var
foo
It is not possible to assign list of null-terminated strings into U-Boot
environment variable. Add optional 'index' parameter to the subcommand
'fdt get value <var> <path> <prop> [<index>]' which lets user specify which
string within the stringlist should be assigned into the 'var' variable.
The default value of 'index' is 0 in case it is not present. This way the
'fdt' command API does not change and existing scripts are not broken.

from zero:
=> fdt get value var / compatible 1 ; print var

produced non-standard output file. And also updated documentation.

Makefile: Fix dependency for u-boot-with-dtb.bin
Makefile uses binman to produce u-boot-with-dtb.bin target. As its input it
takes DTB file and u-boot binary without DTB, which is stored in file
u-boot-nodtb.bin. So fix target dependency.

i2c: stm32: do not set the STOP condition on error
Current function stm32_i2c_message_xfer is sending a STOP
whatever the result of the transaction is. This can cause issues
such as making the bus busy since the controller itself is already
sending automatically a STOP when a NACK is generated.
Thanks to Jorge Ramirez-Ortiz for diagnosing and proposing a first
fix for this. [1]
Functions stm32_i2c_message_start and stm32_i2c_handle_reload
both get a stop boolean indicating if the transfer should end with
a STOP or not. However no specific handling is needed in those
functions hence remove the parameter.
i2c: stm32: fix comment and remove unused AUTOEND bit
Comment within stm32_i2c_message_start is misleading, indicating
that AUTOEND bit is setted while it is actually cleared.
Moreover, the bit is actually never setted so there is no need
to clear it hence get rid of this bit clear and the bit macro
as well.

Commit 5bb2c550b11e ("arm: mvebu: Move internal registers in
arch_very_early_init() function") moved code from file cpu.c to lowlevel.c,
which moves Marvell internal registers from address INTREG_BASE_ADDR_REG to
SOC_REGS_PHY_BASE.
But the steps describing how to do it correctly were documented only in
older U-Boot versions and commit cefd764222ee ("arm: mvebu: Fix internal
register config on A38x") probably unintentionally removed important
details about MMU from code comments around.
Commit 5bb2c550b11e ("arm: mvebu: Move internal registers in
arch_very_early_init() function") implemented code movement according to
(now incomplete) comments which resulted in semi-broken code.
The result is that I-cache is currently disabled for all Armada 38x boards
and maybe there are some other (unreported / undetected) issues.
Reimplement it correctly. First flush all caches, then disable MMU and L2
cache and then move Marvell internal registers. There is no need to
explicitly disable I-cache.
After this change lzmadec command with lzma image of 0x7000000 bytes is
doing decompression just 5 seconds. Before this change it was 30 seconds.
To make lowlevel.S code more readable, extend asm/pl310.h header file to be
compatible with assembler and use macros from this file.

For some unknown reason when L2 cache is disabled on Armada 385 then loadb,
loadx and loady commands do not work with higher baudrates than 115200
(they just abort transfer) and lzmadec command with lzma image of size
0x7000000 (maybe even smaller, we tested this one) is doing decompression
for more than 2 minutes. After enabling L2 cache decompression takes only
30s and loadb, loadx and loady are stable and working fine.
git bisect identified problematic commit 3308933d2fe9 ("arm: mvebu: Avoid
reading MVEBU_REG_PCIE_DEVID register too many times"). Before this commit
above issues were not present.
But investigation showed that above issue was possible to reproduce also by
reverting that commit and forcing compiler to do inline optimization of
mvebu_soc_family() function. Which seems that the root of this issue is in
caches and position of instruction of segments. So currently it is unknown
what is or was broken, but code movement, code inlining or other compiler
optimization triggered it.
Commit 3e5ce7ceeb94 ("arm: mvebu: Enable L2 cache on Armada XP") mentioned
that enabling L2 cache on Armada XP improved performance and that Armada
38x has L2 disabled (which is default state) and if needed it has to be
enabled in separate patch. As enabling L2 cache also improve performance
on Armada 38x, enable it.
Note that Aurora cache in no outer mode is available only on Armada XP,
hence it is not touched for Armada 38x code.
