mtd: rawnand: denali_dt: insert udelay() after reset deassert
When the reset signal is de-asserted, the HW-controlled bootstrap
starts running unless it is disabled in the SoC integration.
It issues some commands to detect a NAND chip, and sets up registers
automatically. Until this process finishes, software should avoid
any register access.
Without this delay function, some of UniPhier boards hangs up while
executing nand_scan_ident(). (denali_read_byte() is blocked)

mtd: rawnand: denali-spl: Add missing hardware init on SoCFPGA
On Altera SoCFPGA, upon either cold-boot or power-on reset, the
Denali NAND IP is initialized by the BootROM ; upon warm-reset,
the Denali NAND IP is NOT initialized by BootROM. In fact, upon
warm-reset, the SoCFPGA BootROM checks whether the SPL image in
on-chip RAM is valid and if so, completely skips re-loading the
SPL from the boot media.
This does sometimes lead to problems where the software left
the boot media in inconsistent state before warm-reset, and
because the BootROM does not reset the boot media, the boot
media is left in this inconsistent state, often until another
component attempts to access the boot media and fails with an
difficult to debug failure. To mitigate this problem, the SPL
on Altera SoCFPGA always resets all the IPs on the SoC early
on boot.
This results in a couple of register values, pre-programmed by
the BootROM, to be lost during this reset. To restore correct
operation of the IP on SoCFPGA, these values must be programmed
back into the controller by the driver. Note that on other SoCs
which do not use the HW-controlled bootstrap, more registers
may have to be programmed.
This also aligns the SPL behavior with the full Denali NAND
driver, which sets these values in denali_hw_init().

spi: nxp_fspi: new driver for the FlexSPI controller
This is a port of the kernel's spi-nxp-fspi driver. It uses the new
spi-mem interface and does not expose the more generic spi-xfer
interface. The source was taken from the v5.3-rc3 tag.
The port was straightforward:
- remove the interrupt handling and the completion by busy polling the
controller
- remove locks
- move the setup of the memory windows into claim_bus()
- move the setup of the speed into set_speed()
- port the device tree bindings from the original fspi_probe() to
ofdata_to_platdata()
There were only some style change fixes, no change in any logic. For
example, there are busy loops where the return code is not handled
correctly, eg. only prints a warning with WARN_ON(). This port
intentionally left most functions unchanged to ease future bugfixes.
This was tested on a custom LS1028A board. Because the LS1028A doesn't
have proper clock framework support, changing the clock speed was not
tested. This also means that it is not possible to change the SPI
speed on LS1028A for now (neither is it possible in the linux driver).
