With of-platdata we always have a dtv struct that holds the platform data
provided by the driver_info record. However, this struct can be empty if
there are no actual devicetree properties provided.
The upshot of empty platform data is that it will end up as a zero-size
member in the BSS section, which is fine. But if the driver specifies
plat_auto then it expects the correct amount of space to be allocated.
At present this does not happen, since device_bind() assumes that the
platform-data size will always be >0. As a result we end up not
allocating the space and just use the BSS region, overwriting whatever
other contents are present.
Fix this by removing the condition that platform data be non-empty, always
allocating space if requested.
This fixes a strange bug that has been lurking since of-platdata was
implemented. It has likely never been noticed since devices normally have
at least some devicetree properties, BSS is seldom used on SPL, the dtv
structs are normally at the end of bss and the overwriting only happens
if a driver changes its platform data.
It was discovered using sandbox_spl, which exercises more features than
a normal board might, and the critical global_data variable 'gd' happened
to be at the end of BSS.

Using the internal vs. external pull resistors it is possible to get
27 different combinations from 3 strapping pins. Add an implementation
of this.
This involves updating the sandbox GPIO driver to model external and
(weaker) internal pull resistors. The get_value() method now takes account
of what is driving a pin:
sandbox: GPIOD_EXT_DRIVEN - in which case GPIO_EXT_HIGH provides the
value
outside source - in which case GPIO_EXT_PULL_UP/DOWN indicates the
external state and we work the final state using those flags and
the internal GPIOD_PULL_UP/DOWN flags
Of course the outside source does not really exist in sandbox. We are just
modelling it for test purpose.

Add a new flag to keep track of whether sandbox is driving the pin, or
whether it is expecting an input signal. If it is driving, then the value
of the pin is the value being driven (0 or 1). If not driving, then we
consider the value 0, since we don't currently handle things like pull-ups
yet.

It is convenient to be able to adjust some of the flags for a GPIO while
leaving others alone. Add a function for this.
Update dm_gpio_set_dir_flags() to make use of this.
Also update dm_gpio_set_value() to use this also, since this allows the
open-drain / open-source features to be implemented directly in the
driver, rather than using the uclass workaround.
Update the sandbox tests accordingly. This involves a lot of changes to
dm_test_gpio_opendrain_opensource() since we no-longer have the direciion
being reported differently depending on the open drain/open source flags.
Also update the STM32 drivers to let the uclass handle the active low/high
logic.

At present we have the concept of a pin's external value. This is what
is used when getting the value of a pin. But we still set the
GPIOD_IS_OUT_ACTIVE flag when changing the value. This is not actually
correct, since if the pin changes from output to input, the external
value need not change. Adjust the logic for this difference.

At present with the sandbox GPIO driver it is not possible to change the
value of GPIOD_IS_OUT_ACTIVE unless the GPIO is an output. This makes it
hard to test changing the flags since we need to be aware of the internal
workings of the driver.
The feature is designed to aid testing.
Split this feature out into a separate sandbox-specific flag, so that the
flags can change unimpeded. This will make it easier to allow updating the
flags in a future patch.

These functions use devicetree and cannot work with of-platdata, which has
no runtime devicetree.
If they are used, the current linker error is confusing, since it talks
about missing functions in the bowels of driver model.
Avoid compiling these functions at all with of-platdata, so that a
straightforward link error points to the problem.

Interrupt for EP0 is indicated in intrtx register via first bit. This bit
is set for both RX and TX despite register has only TX in its name. First
bit in intrrx register is reserved, not used and never set.
So remove calling musb_peri_ep0() function at every iteration of udc_irq()
and musb_peri_rx() and call it only from musb_peri_tx() when correct
interrupt bit in initrtx it set.
Address from SET ADDRESS command must be set to faddr register only after
acknowledging SERV_RXPKTRDY followed by received EP0 interrupt. So prior
calling musb_peri_ep0_set_address() check for EP0 interrupt instead of
(incorrect) MUSB_INTR_SOF interrupt.
This patch fixes issue that host (computer) cannot register U-Boot USB
device and is failing with errors:
usb 1-1: new full-speed USB device number 86 using xhci_hcd

If musb_peri_rx_ep() was called to process received HW buffer but U-Boot
cannot read it yet (e.g. because U-Boot SW buffer is full) then interrupt
was marked as processed also when HW buffer stayed unprocessed.
U-Boot tried to process this buffer again when it received interrupt again,
but it can receive it only when sender (host) sends a new data. As sender
(host) is not going to send a new data until U-Boot process current data
this issue caused a deadlock in case sender (host) is emitting data faster
than U-Boot can process it.
Reading musb intrrx register automatically clears this register and marks
interrupt as processed. So to prevent marking interrupt in U-Boot as
processed, adds a new variable pending_intrrx which would contain
unprocessed bits of intrrx register.
For a second step, every time when musb_peri_rx_ep() is called and there
are waiting data to be processed (signaled by MUSB_RXCSR_RXPKTRDY) either
acknowledge sender (via musb_peri_rx_ack()) that whole HW buffer was
processed or set corresponding bit in pending_intrrx that HW buffer was not
fully processed yet and next iteration is required after U-Boot allocates
space for reading HW buffer.

This patch fixes configuring FIFOs for one-directional endpoints which have
only one queue (either RX or TX, but noth both).
Size of FIFO buffer is 2^(idx+3) bytes and starting address is 2^(addr+3).
Moreover first 64 bytes are reserved for EP0.
Without this patch if FIFO size specified by caller was zero then idx was
incorrectly calculated (expr. ffs(0)-1) and size overflowed in fifosz
register. This register uses has only 4 bits for FIFO size. Moreover
specifying zero buffer size is not possible (with idx=0 is minimal buffer
size 8 bytes).
So even for one-directional endpoints we need to correctly specify both
(RX and TX) FIFO buffer sizes and its addresses.
This patch is fixing calculation of start address and buffer size to
minimal value and ensures that it would not overlap with buffer reserved
for EP0.
This issue caused loose of packets on USB bus in both directions and
basically usbtty was unusable.

Function next_urb() selects the last urb data buffer from linked list to
which next data from usbtty's puts function should be appended.
But to check if TX data still exists it is needed to look at the first urb
data buffer from linked list. So check for endpoint->tx_urb (first from the
linked list) instead of current_urb (the last from the linked list).
Successful call to udc_endpoint_write() may invalidate active urb and
allocate new urb in queue which invalidates pointer returned by next_urb()
function.
So call next_urb() prior putting data into urb buffer and call it every
time after using udc_endpoint_write() function to prevent sending data from
usbtty's puts function in incorrect order.
This patch fixes issue that usbtty code does not transmit data when they
are waiting in the tx queue.

Historically, the reset_cpu() function had an `addr` parameter which was
meant to pass in an address of the reset vector location, where the CPU
should reset to. This feature is no longer used anywhere in U-Boot as
all reset_cpu() implementations now ignore the passed value. Generic
code has been added which always calls reset_cpu() with `0` which means
this feature can no longer be used easily anyway.
Over time, many implementations seem to have "misunderstood" the
existence of this parameter as a way to customize/parameterize the reset
(e.g. COLD vs WARM resets). As this is not properly supported, the
code will almost always not do what it is intended to (because all
call-sites just call reset_cpu() with 0).
To avoid confusion and to clean up the codebase from unused left-overs
of the past, remove the `addr` parameter entirely. Code which intends
to support different kinds of resets should be rewritten as a sysreset
driver instead.
This transformation was done with the following coccinelle patch:

- reset_cpu(argvalue)

The relevant changes to the already existing GD5F1GQ4UExxG support has
been determined by consulting the GigaDevice product change notice
AN-0392-10, version 1.0 from November 30, 2020.
As the overlaps are huge, variable names have been generalized
accordingly.
Apart form the lowered ECC strength (4 instead of 8 bits per 512 bytes),
the new device ID, and the extra quad IO dummy byte, no changes had to
be taken into account.
New hardware features are not supported, namely:
- Power on reset
- Unique ID
- Double transfer rate (DTR)
- Parameter page
- Random data quad IO
The inverted semantic of the "driver strength" register bits, defaulting
to 100% instead of 50% for the Q5 devices, got ignored as the driver has
never touched them anyway.
The no longer supported "read from cache during block erase"
functionality is not reflected as the current SPI NAND core does not
support it anyway.
Implementation has been tested on MediaTek MT7688 based GARDENA smart
Gateways using both, GigaDevice GD5F1GQ5UEYIG and GD5F1GQ4UBYIG.
