dm: core: Fix allocation of empty of-platdata
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.

reset: Remove addr parameter from reset_cpu()
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:
The parameter passed to reset_cpu() no longer holds a meaning as all
call-sites now pass the value 0. Thus, branching on it is essentially
dead code and will just confuse future readers.

board: ns3: Remove superfluous reset logic
The current implementation of reset_cpu() in the ns3 board code does not
archieve what it is supposed to (according to the comments), due to
a number of reasons:
1. The argument to reset_cpu() is _not_ actually passed from the
`reset` command, but is set to 0 in all call-sites (in this
specific case, see arch/arm/lib/reset.c). Thus, performing
different kinds of resets based on its value will not work as
expected.
2. Contrary to its documentation, the passed argument is not
interpreted, but a static `L3_RESET` define is used. The other
comment properly notes that this will always perform a L3 reset,
though.
3. The "parsing" of the static `L3_RESET` value is not even using the
upper and lower nibble as stated in the comment, but uses the last
two decimal digits of the value.
This is currently one of the only implementations left in U-Boot, which
make "use" of the value passed to reset_cpu(). As this is done under
false assumption (the value does not have any meaning anymore), it makes
sense to bring it into line with the rest and start ignoring the
parameter.

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.

mtd: nand: spi: Only one dummy byte in QUADIO
The datasheet only lists one dummy byte in the 0xEB operation for the
following chips:
* GD5F1GQ4xExxG
* GD5F1GQ4xFxxG
* GD5F1GQ4UAYIG
* GD5F4GQ4UAYIG
Reto Schneider:
- Linux patch ported to U-Boot
- Checked for compatibility with GD5F1GQ4xBxxG
- Fixed operation code in original commit message (0xEH -> 0xEB)

If there is an error while erasing SPI flash, no errno is displayed. This
makes it difficult to determine the cause of the error. This change mirrors
the logic for write errors above.

spi: nxp_fspi: Fix error reporting
On the i.MX8M Mini, ret = clk_set_rate() sets ret to the value of the

checks that it is not NULL. Since positive numbers are not errors,
only check for negative numbers when handling errors.

ddr: marvell: a38x: fix comment in conditional macro
The code was processed with unifdef utility to omit portions not
relevant to A38x and DDR3. This removes usage of many macros, including
A70X0, A80X0 and A3900. It seems that the unifdef utility did not remove
the macros from #else comment.
