From reading the S34ML02G1 and the SAM9X60 datasheets again, it seems
like we have to wait tREA after rising RE# before sampling the data.
Thus pulse time must be at least tREA.

Without this fix we got PMECC errors when reading, after switching to
ONFI timing mode 3 on SAM9X60 SoC with S34ML02G1 raw NAND flash chip.

The approach to set timings used before worked on sam9g20 and sama5d2
with the same flash (S34ML02G1), probably because those have a slower
mck clock rate and thus the resolution of the timings setup is not as
tight as with sam9x60.

The approach to fix the issue was carried over from at91bootstrap, and
has been successfully tested in at91bootstrap, U-Boot and Linux.

In Linux DT,the pinctrl node acts as parent nodes with all other
gpio banks as child nodes and a single driver in Linux handles both
pinctrl settings and gpio requests.Current U-Boot DT maintains both
pinctrl and gpio nodes as separate nodes and offers two different class
of U-Boot drivers: UCLASS_PINCTRL which handles pin functions and
UCLASS_GPIO which handles gpio requests. In order to align the DT
of U-Boot with the DT of Linux, a hook is been added in the pinctrl
driver to bind the gpio driver with the pinctrl driver so that
when adding gpio nodes as subnodes to pinctrl node (as per the Linux ABI),
the corresponding APIs will be redirected and handled by valid
drivers attached to the pinctrl driver.

The qspi controller on sama5d2 and sam9x60 supports "classic" SPI mode
without spi-mem enhancements and accelerations, very similar to the old
SPI controller on sam9g20 or the modern flexcom controllers of the same
SoC family.

Register interface differs somewhat, especially because only one
hardware controlled CS line is supported.  Some fields are missing, some
are in different registers, but in principal it works similar.  So code
is very much inspired by the old atmel-spi driver.

Tested on sam9x60 with a non-mainline driver to configure an FPGA.

Switching between Serial Memory Mode (SMM) and (classic) SPI mode is a
preparation for implementing .xfer() in the future.

Signed-off-by: Alexander Dahl <ada@thorsis.com>

The Serial Memory Mode (SMM) is enabled with atmel_qspi_set_cfg() on
each invocation of atmel_qspi_exec_op().  Setting SMM through
atmel_qspi_init() at probe time is redundant.

Removing the SMM setting at probe time should therefore 1) be safe to do
and 2) allows for setting it to a different value in a future
implementation of .xfer() which needs to disable SMM.

Report of the static analyzer:
1. NULL_AFTER_DEREF Pointer 'str', which is dereferenced at
   image-host.c:688 by calling function 'strdup', is compared to a NULL
   value at image-host.c:691.
2. NULL_AFTER_DEREF Pointer 'list', which is dereferenced at
   image-host.c:689, is compared to a NULL value at image-host.c:691.

Corrections explained:
1. Checking for NULL before using pointers: The if (!list || !str) check
   is now performed before calling strdup and realloc, which prevents
   null pointer dereferences.
2. Checking the result of strdup: strdup can return NULL if memory
   allocation fails. This also needs to be checked.
3. Checking the result of realloc: If realloc returns NULL, then memory
   has not been allocated and dup must be freed to avoid memory leaks.
