Drop 1ms delay in fsl_esdhc command sending
Revert "mmc: sdhci: set to INT_DATA_END when there are data"
Since the beginning of this driver which was initially for the MPC8379
and MPC8536 SoCs, there is this spurious 1ms delay. According to the
comment it should actually be only 8 clock cycles. Esp. during EFI block
transfers, this 1ms add up to a significant delay and slows down EFI
boot.
I couldn't find any mention in the MPC8536 that there should be a delay
of 8 clock cycles between commands. The SD card specification mentions that
the clock has to be left enabled for 8 cycles after a command or
response. But I don't see how this delay will help with this.
Go ahead and just remove it. If there will ever be any regression we can
introduce a compile time flag, but for now I'd like to keep it simple.

While a board could have multiple SATA ports, some of the ports might
not have a disk attached to them. So while probing for disks,
sata_mv_probe() should continue probing all ports, and skip one with

If a board has 2 or more SATA ports, and there is only one disk

A rather common kind of external watchdog circuit is one that is kept
alive by toggling a gpio. Add a driver for handling such a watchdog.
The corresponding linux driver apparently has support for some
watchdog circuits which can be disabled by tri-stating the gpio, but I
have never actually encountered such a chip in the wild; the whole
point of adding an external watchdog is usually that it is not in any
way under software control. For forward-compatibility, and to make DT
describe the hardware, the current driver only supports devices that
have the always-running property. I went a little back and forth on
whether I should fail ->probe or only ->start, and ended up deciding
->start was the right place.
The compatible string is probably a little odd as it has nothing to do
with linux per se - however, I chose that to make .dts snippets
reusable between device trees used with U-Boot and linux, and this is
the (only) compatible string that linux' corresponding driver and DT
binding accepts. I have asked whether one should/could add "wdt-gpio"
to that binding, but the answer was no:
https://lore.kernel.org/lkml/CAL_JsqKEGaFpiFV_oAtE+S_bnHkg4qry+bhx2EDs=NSbVf_giA@mail.gmail.com/
If someone feels strongly about this, I can certainly remove the
"linux," part from the string - it probably wouldn't the only place where
one can't reuse a DT snippet as-is between linux and U-Boot.

A board can have and make use of more than one watchdog device, say
one built into the SOC and an external gpio-petted one. Having
wdt-uclass only handle the first is both a little arbitrary and
unexpected.
So change initr_watchdog() so we visit (probe) all DM watchdog
devices, and call the init_watchdog_dev helper for each.
Similarly let watchdog_reset() loop over the whole uclass - each
having their own ratelimiting metadata, and a separate "is this device
running" flag.
This gets rid of the watchdog_dev member of struct global_data. We
do, however, still need the GD_FLG_WDT_READY set in
initr_watchdog(). This is because watchdog_reset() can get called
before DM is ready, and I don't think we can call uclass_get() that
early.
The current code just returns 0 if "getting" the first device fails -
that can of course happen because there are no devices, but it could
also happen if its ->probe call failed. In keeping with that, continue
with the handling of the remaining devices even if one fails to
probe. This is also why we cannot use uclass_probe_all().
If desired, it's possible to later add a per-device "u-boot,autostart"
boolean property, so that one can do CONFIG_WATCHDOG_AUTOSTART
per-device.

wdt_start() does the "no ->start? return -ENOSYS" check, don't
open-code that in wdt_expire_now().
Also, wdt_start() maintains some global (and later some per-device)

that it matters much here since the board is supposed to reset very

As per SD spec when SD host controller is reset, it takes 1000msec
to detect the card state. In case, if we enable the sd bus voltage &
card detect state is not stable, then host controller will disable
the sd bus voltage.
In case of warm/subsystem reboot, due to unstable card detect state
host controller is disabling the sd bus voltage to sd card causing
sd card timeout error. So we wait for a maximum of 1000msec to get
the card detect state stable before we enable the sd bus voltage.
This current fix is workaround for now, this needs to be analysed
further. Zynqmp platform should behave the same as Versal, but we

Returning fabricated CRS value (0xFFFF0001) by PCIe Root Complex to OS is
allowed only for 4-byte PCI_VENDOR_ID config read request and only when
CRSSVE bit in Root Port PCIe device is enabled. In all other error PCIe
Root Complex must return all-ones.
So implement this logic in pci-aardvark.c driver properly.
aardvark HW does not have Root Port PCIe device and U-Boot does not
implement emulation of this device. So expect that CRSSVE bit is set as
U-Boot can already handle CRS value for PCI_VENDOR_ID config read request.
More callers of pci_bus_read_config() function in U-Boot do not check for
return value, but check readback value. Therefore always fill readback
value in pcie_advk_read_config() function. On error fill all-ones of
correct size as it is required for PCIe Root Complex.
And also correctly propagates error from failed config write request to
return value of pcie_advk_write_config() function. Most U-Boot callers
ignores this return value, but it is a good idea to return correct value
from function.
These issues about return value of failed config read requests, including
special handling of CRS were reported by Lorenzo and Bjorn for Linux kernel
driver pci-aardvark together with quotes from PCIe r4.0 spec, see details:

During cold start, with some HDDs, mv_sata_identify() does not populate
the ID words on the 1st ATA ID command. In fact, the first ATA ID
command will only power up the drive, and then the ATA ID command
processing is lost in the process.
Tests with:
- Seagate ST9250320AS 250GB HDD and Seagate ST4000DM004-2CV104 4TB HDD.
- Zyxel NSA310S (Kirkwood 88F6702), Marvell Dreamplug (Kirkwood 88F6281),
Seagate GoFlex Home (Kirkwood 88F6281), Pogoplug V4 (Kirkwood 88F6192).
Observation:
- The Seagate ST9250320AS 250GB took about 3 seconds to spin up.
- The Seagate ST4000DM004-2CV104 4TB took about 8 seconds to spin up.
- mv_sata_identify() did not populate the ID words after the call to
mv_ata_exec_ata_cmd_nondma().
- Attempt to insert a long delay of 30 seconds, ie. mdelay(30_000), after
the call to ata_wait_register() inside mv_ata_exec_ata_cmd_nondma() did
not help with the 4TB drive. The ID words were still empty after that 30s
delay.
Patch Description:
- Added a second ATA ID command in mv_sata_identify(), which will be
executed if the 1st ATA ID command did not return with valid ID words.
- Use the HDD drive capacity in the ID words as a successful indicator of
ATA ID command.
- In the scenario where a box is rebooted, the 1st ATA ID command is always
successful, so there is no extra time wasted.
- In the scenario where a box is cold started, the 1st ATA command is the
power up command. The 2nd ATA ID command alleviates the uncertainty of
how long we have to wait for the ID words to be populated by the SATA
controller.

At present it is possible to call uclass_get() before driver model is
inited. In fact this happens on x86 boards which use Intel FSPv1, since
mrccache_get_region() tries to get the SPI flash device very early
during init.
This has always been undefined behaviour. Previously it generally worked,
i.e. returned an error code without crashing, because gd->uclass_root_s
is zeroed and the uclass can be added despite driver model not being
ready, due to the way lists are implemented. With the change to use a
gd->uclass_root pointer, this no-longer works. For example, it causes a
hang on minnowmax.
Fix this by adding a check that driver model is ready when uclass_get() is
called. This function is called in the process of locating any device, so
it is a good place to add the check.
This fixes booting on minnowmax.
