The driver adds the support for the STMicroelectronics FMC2 NAND
Controller found on STM32MP SOCs.
This patch adds the polling mode, a basic mode that do not need
any DMA channels.
Only NAND_ECC_HW mode is actually supported.
The driver supports a maximum 8k page size.
The following ECC strength and step size are currently supported:
- nand-ecc-strength = <8>, nand-ecc-step-size = <512> (BCH8)
- nand-ecc-strength = <4>, nand-ecc-step-size = <512> (BCH4)
- nand-ecc-strength = <1>, nand-ecc-step-size = <512> (Extended ECC
based on Hamming)
This patch has been tested on Micron MT29F8G08ABACAH4.

We are facing issues in the driver since SPI NOR framework has moved
on SPI MEM framework, and SPI NAND framework is not running properly
with the current driver.
To be able to solve issues met on SPI NOR Flashes and to be able to
support SPI NAND Flashes, the driver has been reworked. We are now using
exec_op ops instead of using xfer ops.
Thanks to this rework, the driver has been successfully tested with:
- mx66l51235l SPI NOR Flash on stm32f746 SOC
- n25q128a SPI NOR Flash on stm32f769 SOC
- mx66l51235l SPI NOR Flash on stm32mp1 SOC

Update the memory layout to be aligned with other platform and avoid
overlap with 32MB Linux kernel (multiv7 image).
+ Kernel => 32MiB offset = 0xC2000000
and increase the bootm size to 32MiB
+ FDT => 64MiB offset = 0xc4000000
+ SCRIPT => 65Mib offset = 0xc4100000
+ PXESCRIPT => 66Mib offset = 0xc4200000
+ SPLASHIMAGE => 67Mib offset = 0xc4300000
+ RAMDISK => 68Mib offset = 0xc4400000
(not limited size)
In sources/boot/u-boot/doc/README.distro
+ kernel_addr_r: A size of 16MB for the kernel is likely adequate.
+ pxefile_addr_r: A size of 1MB for extlinux.conf is more than adequate.
+ fdt_addr_r: A size of 1MB for the FDT/DTB seems reasonable.
+ ramdisk_addr_r: It is recommended that this location be highest in RAM
out of fdt_addr_, kernel_addr_r, and ramdisk_addr_r,
so that the RAM disk can vary in size and use any
available RAM.
+ pxefile_addr_r: A size of 1MB for extlinux.conf is more than adequate.
+ scriptaddr: A size of 1MB for extlinux.conf is more than adequate.
For suggestions on memory locations for ARM systems, you must follow
the guidelines specified in Documentation/arm/Booting
in the Linux kernel tree.
And in sources/linux-stm32mp/Documentation/arm/Booting
The zImage may also be placed in system RAM and called there. The
kernel should be placed in the first 128MiB of RAM. It is recommended
that it is loaded above 32MiB in order to avoid the need to relocate
prior to decompression, which will make the boot process slightly
faster.
