2019-10-24mtd: Add TI HyperBus Memory Controller driverVignesh Raghavendra1-0/+7
AM654/J721e has HyperBus Memory Controller that supports HyperFlash and HyperRAM devices. It provides a memory mapped interface to interact with these devices. Add a driver to support the same. Driver calibrates the controller, setups up for MMIO access and probes HyperFlash child node. Signed-off-by: Vignesh Raghavendra <vigneshr@ti.com> Reviewed-by: Stefan Roese <sr@denx.de>
2018-11-13mtd: Drop duplicate MTD_PARTITIONS Kconfig optionBoris Brezillon1-6/+0
Commit 9c5b00973bce ("Convert CONFIG_MTD_PARTITIONS et al to Kconfig") introduced a publicly visible Kconfig entry for the CONFIG_MTD_PARTITIONS option, while the rework on MTD partitioning was in progress, and we somehow did not notice that the same Kconfig entry was added by commit 4048a5c519a8 ("mtd: declare MTD_PARTITIONS symbol in Kconfig"), but this time as an invisible entry (this can only be selected by other options). Keep the non-visible version of this symbol, since MTD_PARTITIONS is not something the user should be able to enable/disable directly.

2018-09-20mtd: declare MTD_PARTITIONS symbol in KconfigMiquel Raynal1-0/+3
UBI selects MTD_PARTITIONS which is the symbol to compile drivers/mtd/mtdpart.c. Unfortunately, the symbol was not defined in Kconfig and this worked only with board files defining it. Fix this by adding a boolean in Kconfig so boards defined by defconfig files only will work as expected.

2017-02-12flash: complete CONFIG_SYS_NO_FLASH move with renamingMasahiro Yamada1-0/+5
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>

2016-05-21drivers: mtd: add Microchip PIC32 internal non-CFI flash driver.Purna Chandra Mandal1-0/+7
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.

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>
