dm: implement a MTD uclass Implement a Memory Technology Device (MTD) uclass. It should include most flash drivers in the future. Though no uclass ops are defined yet, the MTD ops could be used. The NAND flash driver is based on MTD. The CFI flash and SPI flash support MTD, too. It should make sense to convert them to MTD uclass. Signed-off-by: Thomas Chou <thomas@wytron.com.tw>

help
Enable driver model for Memory Technology Devices (MTD), such as
flash, RAM and similar chips, often used for solid state file
systems on embedded devices.
flash: complete CONFIG_SYS_NO_FLASH move with renaming We repeated partial moves for CONFIG_SYS_NO_FLASH, but this is not completed. Finish this work by the tool. During this move, let's rename it to CONFIG_MTD_NOR_FLASH. Actually, we have more instances of "#ifndef CONFIG_SYS_NO_FLASH" than those of "#ifdef CONFIG_SYS_NO_FLASH". Flipping the logic will make the code more readable. Besides, negative meaning symbols do not fit in obj-$(CONFIG_...) style Makefiles. This commit was created as follows: [1] Edit "default n" to "default y" in the config entry in common/Kconfig. [2] Run "tools/moveconfig.py -y -r HEAD SYS_NO_FLASH" [3] Rename the instances in defconfigs by the following: find . -path './configs/*_defconfig' | xargs sed -i \ -e '/CONFIG_SYS_NO_FLASH=y/d' \ -e 's/# CONFIG_SYS_NO_FLASH is not set/CONFIG_MTD_NOR_FLASH=y/' [4] Change the conditionals by the following: find . -name '*.[ch]' | xargs sed -i \ -e 's/ifndef CONFIG_SYS_NO_FLASH/ifdef CONFIG_MTD_NOR_FLASH/' \ -e 's/ifdef CONFIG_SYS_NO_FLASH/ifndef CONFIG_MTD_NOR_FLASH/' \ -e 's/!defined(CONFIG_SYS_NO_FLASH)/defined(CONFIG_MTD_NOR_FLASH)/' \ -e 's/defined(CONFIG_SYS_NO_FLASH)/!defined(CONFIG_MTD_NOR_FLASH)/' [5] Modify the following manually - Rename the rest of instances - Remove the description from README - Create the new Kconfig entry in drivers/mtd/Kconfig - Remove the old Kconfig entry from common/Kconfig - Remove the garbage comments from include/configs/*.h Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

bool "Enable Driver Model for CFI Flash driver"
depends on MTD
help
The Common Flash Interface specification was developed by Intel,
AMD and other flash manufactures. It provides a universal method
for probing the capabilities of flash devices. If you wish to
support any device that is CFI-compliant, you need to enable this
option. Visit <http://www.amd.com/products/nvd/overview/cfi.html>
for more information on CFI.
mtd: add altera quadspi driver Add Altera Generic Quad SPI Controller support. The controller converts SPI NOR flash to parallel flash interface. So it is not like other SPI flash, but rather like CFI flash. Signed-off-by: Thomas Chou <thomas@wytron.com.tw>

Altera Generic Quad SPI Controller. The controller converts SPI
NOR flash to parallel flash interface. Please find details on the
"Embedded Peripherals IP User Guide" of Altera.
drivers: mtd: add Microchip PIC32 internal non-CFI flash driver. PIC32 internal flash devices are parallel NOR flash divided into number of banks to allow erase-programming in one while fetch and execution continues on other. As the flash banks are memory mapped stored code can be executed directly from flash (XIP), also there is additional hardware logic to prefetch and cache contents to improve execution performance. These flash can also be used to store user data (like environment). Flash erase and programming are handled by on-chip NVM controller. Driver implemented driver model but MTD is not really support.
