mtd: spi-nor: enable protection ops for SST26 flash series

2019-09-16T02:39:22+00:00

Commit c4e8862308d4 (mtd: spi: Switch to new SPI NOR framework)
performs switch from previous 'spi_flash' infrastructure without
proper testing/investigations which results in a regressions for
SST26 flash series.

Enable protection ops for SST26 flash series which were
previously enabled by
Commit 3d4fed87a5fa (mtd: sf: Add support of sst26wf* flash ICs
protection ops)

mtd: spi: Drop sf.c

2019-09-16T02:39:22+00:00

spi_write_then_read, will manage to do the respective
spi_xfer based on the tx_buf, rx_buf so drop the
legacy spi_flash_read/write/cm code.

mtd: spi_dataflash: Use spi read then write

2019-09-16T02:39:22+00:00

Now, we have spi_write_then_read routine that would handle
spi_xfer handling based on the tx_buf and rx_buf parameters.

So, replace individual flash read/write/cmd transfer call
with spi_write_then_read.

mtd: nand: raw: Move CONFIG_SYS_NAND_USE_FLASH_BBT to Kconfig

2019-08-26T00:58:37+00:00

Convert CONFIG_SYS_NAND_USE_FLASH_BBT to Kconfig, update defconfigs,
headers and whitelist.

Please note that this symbol already was used in Kconfig
(imply in CONFIG_NAND_ATMEL) which did not work, since this symbol was
not available in Kconfig. This changes now with this patch and all
boards with CONFIG_NAND_ATMEL will have BBT enabled. Which is what
I also need on my GARDENA AT91SAM based board.

env: Rename environment.h to env_internal.h

2019-08-11T23:27:31+00:00

This file contains lots of internal details about the environment. Most
code can include env.h instead, calling the functions there as needed.

Rename this file and add a comment at the top to indicate its internal
nature.

nand: davinci: add support for driver model

2019-07-29T21:58:52+00:00

Extend the davinci NAND driver to support the driver model. For now this
doesn't add any device-tree parsing due to the fact that we can't access
the actual nand node on the device-tree - it's a subnode of the aemif
device and we don't have an aemif driver on davinci at the moment.
