Trying to clear PIO_START register when it is non-zero (which indicates
that previous PIO transfer has not finished yet) causes an External
Abort with SError 0xbf000002.
This bug is currently worked around in TF-A by handling External Aborts
in EL3 and ignoring this particular SError.
This workaround was also discussed at:
https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/commit/?id=3c7dcdac5c50https://lore.kernel.org/linux-pci/20190316161243.29517-1-repk@triplefau.lt/https://lore.kernel.org/linux-pci/971be151d24312cc533989a64bd454b4@www.loen.fr/https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/1541
Implement a proper fix to prevent this External Abort. As it is not
possible to cancel a pending PIO transfer, simply do not start a new one
if previous has not finished yet. In this case return an error to the
caller.
In most cases this SError happens when there is no PCIe card connected
or when PCIe link is down. The reason is that in these cases a PIO
transfer takes about 1.44 seconds. For this reason we also increase the
wait timeout in pcie_advk_wait_pio() to 1.5 seconds.
If PIO read transfer for PCI_VENDOR_ID register times out, or if it
isn't possible to read it yet because previous transfer is not finished,
return Completion Retry Status value instead of failing, to give the
caller a chance to send a new read request.

According to S26KL512S datasheet [1] and S29GL01GS datasheet [2],
the procedure to read out PPB lock bits is to send the PPB Entry,
PPB Read, Reset/ASO Exit. Currently, the code does send incorrect
PPB Entry, PPB Read and Reset/ASO Exit is completely missing.
The PPB Entry sent is implemented by sending flash_unlock_seq()
and flash_write_cmd(..., FLASH_CMD_READ_ID). This translates to
sequence 0x555:0xaa, 0x2aa:0x55, 0x555:0x90=FLASH_CMD_READ_ID.
However, both [1] and [2] specify the last byte of PPB Entry as
0xc0=AMD_CMD_SET_PPB_ENTRY instead of 0x90=FLASH_CMD_READ_ID,
that is 0x555:0xaa, 0x2aa:0x55, 0x555:0xc0=AMD_CMD_SET_PPB_ENTRY.
Since this does make sense, this patch fixes it and thus also
aligns the code in flash_get_size() with flash_real_protect().
The PPB Read returns 00h in case of Protected state and 01h in case
of Unprotected state, according to [1] Note 83 and [2] Note 17, so
invert the result. Moreover, align the arguments with similar code
in flash_real_protect().
Finally, Reset/ASO Exit command should be executed to exit the PPB
mode, so add the missing reset.

Having WATCHDOG_RESET() called automatically from the timer interrupt
runs counter to the idea of a watchdog device - if the board runs into
an infinite loops with interrupts still enabled, the watchdog will
never fire.
When using CONFIG_(SPL_)WDT, the watchdog_reset function is a lot more
complicated than just poking a few SOC-specific registers - it
involves accessing all kinds of global data, and if the interrupt
happens at the wrong time (say, in the middle of an WATCHDOG_RESET()
call from ordinary code), that can end up corrupting said global data.
Allow the board to opt out of calling WATCHDOG_RESET() from the timer
interrupt handler by setting CONFIG_SYS_WATCHDOG_FREQ to 0 - as that
setting is currently nonsensical (it would be compile-time
divide-by-zero), it cannot affect any existing boards.
Add documentation for both the existing and extended meaning of
CONFIG_SYS_WATCHDOG_FREQ.

Some boards don't work with the rate-limiting done in the generic
watchdog_reset() provided by wdt-uclass.
For example, on powerpc, get_timer() ceases working during bootm since
interrupts are disabled before the kernel image gets decompressed, and
when the decompression takes longer than the watchdog device
allows (or enough of the budget that the kernel doesn't get far enough
to assume responsibility for petting the watchdog), the result is a
non-booting board.
As a somewhat hacky workaround (because DT is supposed to describe
hardware), allow specifying hw_margin_ms=0 in device tree to
effectively disable the ratelimiting and actually ping the watchdog
every time watchdog_reset() is called. For that to work, the "has
enough time passed" check just needs to be tweaked a little to allow
the now==next_reset case as well.

Replace the pure SUN8I_H3 symbol with the joint SUNXI_H3_H5 one, which is

changes necessary to support MIPS Octeon via DT based probing are, to
add the compatible DT property and the use of dev_remap_addr() so that
the correct mapped address is used in the Octeon case (phys != virt).
Please note that this driver supports the usage of the "scsi" command
and not the "sata" command, since it does not provide an own "scan"
function, which is needed for the "sata" cmd support.

This fixes an issue getting resets index 1 and 3+, the spurius "> 0"

catches it and this fixes the regression.

Having WATCHDOG_RESET() called automatically from the timer interrupt
runs counter to the idea of a watchdog device - if the board runs into
an infinite loops with interrupts still enabled, the watchdog will
never fire.
When using CONFIG_(SPL_)WDT, the watchdog_reset function is a lot more
complicated than just poking a few SOC-specific registers - it
involves accessing all kinds of global data, and if the interrupt
happens at the wrong time (say, in the middle of an WATCHDOG_RESET()
call from ordinary code), that can end up corrupting said global data.
Allow the board to opt out of calling WATCHDOG_RESET() from the timer
interrupt handler by setting CONFIG_SYS_WATCHDOG_FREQ to 0 - as that
setting is currently nonsensical (it would be compile-time
divide-by-zero), it cannot affect any existing boards.
Add documentation for both the existing and extended meaning of
CONFIG_SYS_WATCHDOG_FREQ.

Some boards don't work with the rate-limiting done in the generic
watchdog_reset() provided by wdt-uclass.
For example, on powerpc, get_timer() ceases working during bootm since
interrupts are disabled before the kernel image gets decompressed, and
when the decompression takes longer than the watchdog device
allows (or enough of the budget that the kernel doesn't get far enough
to assume responsibility for petting the watchdog), the result is a
non-booting board.
As a somewhat hacky workaround (because DT is supposed to describe
hardware), allow specifying hw_margin_ms=0 in device tree to
effectively disable the ratelimiting and actually ping the watchdog
every time watchdog_reset() is called. For that to work, the "has
enough time passed" check just needs to be tweaked a little to allow
the now==next_reset case as well.

Commit eb5a2b6710 ("net: sun8i-emac: Determine pinmux based on SoC,
not EMAC type") switched the pinmux setup over to look at
CONFIG_MACH_SUN* symbols, to find the appropriate mux value.
Unfortunately this patch missed to check for the H5, which is
pin-compatible to the H3, but uses a different Kconfig symbol (because
it has ARMv8 vs. ARMv7 cores).
Replace the pure SUN8I_H3 symbol with the joint SUNXI_H3_H5 one, which is
there to cover the peripherals common to both SoCs.
Also explicitly list each supported SoC, and have an error message in the
fallback case, to avoid those problems in the future.
This fixes Ethernet support on all H5 boards.

According to EHCI spec, software needs to do handshake with HC for
safely removing QH from async list. This handshake is implemented by
setting IAAD (Interrupt on Async Advance Doorbell) bit in USB_USBCMD
register and poll the IAA (Interrupt on Async Advance bit) in the
USB_USBSTS to ensure the HC has released all on-chip state that may
potentially reference one of the data structures just removed.
Current codes only check active status of the last QTD, but this can't
ensure the QH is released from HC. We can meet unrecoverable
"EHCI timed out on TD" errors when running UEFI SCT tests on USB disk.
The USB_ASYNCLISTADDR register is changed to a invalid address when the
issue happens. It is fixed after adding the IAA handshake.
Steps to reproduce the issue:
1. Build the UEFI SCT from https://github.com/tianocore/edk2-test
2. Build the EDK2 UEFI Shell from https://github.com/tianocore/edk2
3. Copy SCT files and Shell.efi to USB disk FAT partition
4. Load the Shell.efi from USB FAT, and run bootefi to execute it
5. After booting into Shell, enter the SCT directory and run "sct -a"
to execute all tests.
6. Tests run about 1 hour and stop with many EHCI timeout errors like

To squash that nasty warning message and make better use of the newly
gained OF_CONTROL feature, let's convert the calxedagmac driver to the
"new" driver model.
The conversion is pretty straight forward, mostly just adjusting the
use of the involved data structures.
The only actual change is the required split of the receive routine into
a receive and free_pkt part.
Also this allows us to get rid of the hardcoded platform information and
explicit init calls.
This also uses the opportunity to wrap the code decoding the MMIO
register base address, to make it safe for using PHYS_64BIT later.
