mtd: nand: build MXS driver for MX7 as well

2017-02-19T15:20:28+00:00

The i.MX7 has the same GPMI controller as i.MX6 and is covered by the MXS
driver. Tell Kconfig that we can use this driver on the MX7 platform (the MXS
driver already has the few i.MX7-specific changes needed for basic operation
and the board itself sets the pinmux correctly).

Tested on i.MX7D with the Sabre board and a NAND Flash soldered to U12.

flash: complete CONFIG_SYS_NO_FLASH move with renaming

2017-02-12T19:30:25+00:00

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

dm: core: Replace of_offset with accessor

2017-02-08T13:12:14+00:00

At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

mtd: nand: mxs_nand_spl: Fix to remove twise 'NAND' print

2017-01-04T15:56:44+00:00

SPL from nand will print 'NAND' in boot_from_devices based on
the image_loader name, remove the extra 'NAND ' in mxs_nand_spl driver.

Original behaviour:

Revert "sf: Fix quad bit set for micron devices"

2016-12-15T17:33:16+00:00

This reverts commit c56ae7519f141523ba1248b22b5b5169b21772fe.

Once the 'Quad Enable' bit is cleared in their Enhanced Volatile
Configuration Register (EVCR), Micron memories expect ALL commands to use
the SPI 4-4-4 protocol. Commands using SPI 1-y-z protocols are no longer
accepted.

Within the reverted commit, the write_evcr() function is implemented using
the spi_flash_write_common(), which is a shortcut for the
[ spi_flash_cmd_write_enable(), spi_flash_cmd_write(),
spi_flash_cmd_wait_ready() ] sequence.

Since the internal state of the Micron memory has been changed when the
spi_flash_cmd_write() function completes, the later call of the
spi_flash_cmd_wait_ready() function fails.

Indeed the SPI controller driver is not aware of the SPI protocol switch.

Further patches will fix the support of Micron QSPI memories.

sf: Do not force the DT memory map size to exactly match the device

2016-12-15T15:57:28+00:00

As long as the memory mapped size specifeid in the DT is the same or
bigger than the device size, it will work. So do not force the sizes
to be identical.

mtd: spi: don't return -1 when scan succeed

2016-12-15T15:57:28+00:00

In spi_flash_scan, 'ret' is initialled to -1, but 'ret' is not always
used to store a return value, in that case, even when the function
succeed, an error (-1) will be returned.
Lets just return 0 if we hit the end of the function.
