Masahiro Yamada e856bdcfb4 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

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.

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.

help
This enables access to Altera EPCQ/EPCS flash chips using the
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.
