2017-02-12flash: compile common/flash.c iif CONFIG_MTD_NO_FLASH is enabledMasahiro Yamada
The whole of common/flash.c is guarded by #if defined() ... #endif. Move the conditional to common/Makefile. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2017-02-12flash: complete CONFIG_SYS_NO_FLASH move with renamingMasahiro Yamada
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>

2013-04-22flash: Add optional verify-after-write featureStefan Roese
Sometimes it might make sense to verify the written data to NOR flash. This patch adds this feature. To enable this verify-after-write, you need to define CONFIG_FLASH_VERIFY in your board config header. Please note that this option is useless in nearly all cases, since such flash programming errors usually are detected earlier while unprotecting/erasing/programming. Please only enable this option if you really know what you are doing. Signed-off-by: Stefan Roese <sr@denx.de>
2012-09-03cfi: Make the flash erase and write operations abortableJoe Hershberger
Check for ctrlc() in operations that take time and loop over the flash addresses. In netconsole, tstc() is expensive. Only check once in a while to not slow down the operation significantly. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Signed-off-by: Stefan Roese <sr@denx.de>
2010-09-20cfi_flash: Simplify dynamic flash bank number detectionStefan Roese
This patch simplifies the use of CONFIG_SYS_MAX_FLASH_BANKS_DETECT. By moving these optional variables and defines into the common code, board specific code is minimized. Currently only the following board use this feature: APC405, IDS8247, TQM834x And IDS8247 doesn't seem to really need this feature, since its not updating the bank number variable at all. So this patch removes the definition of CONFIG_SYS_MAX_FLASH_BANKS_DETECT from this board port. This new framework will be used by the upcoming lwmon5 update as well.

2010-08-09flash_protect: check for NULL flash infoMike Frysinger
If a flash is unable to be detected, and then someone calls flash_protect on it (like the common code does in flash_init), the flash_protect logic will dereference a NULL pointer. Since flash_protect already does sanity checking on the info structs, add a NULL pointer check in there. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
