[U-Boot] [PATCH v4 00/21] sf: Tunning spi-flash layer

[Jagan Teki]

Previous version link:

spi-flash layer need to tune a lot for better code handling and
to sync with Linux spi-nor. So below areas got updated in this series.
- BAR handling
- spi_flash_cmd_wait_ready updates.
- Separate core spi-flash handling and spi-flash interface
  (interface between spi drivers vs spi-flash layer)

Currently I'm working on spi-nor framework for u-boot which
is slighly same as Linux spi-nor core with addition of
u-boot driver model to it.

This series will be starting point to add spi-nor functionalities.

TODO:
- MTD core addition to spi-flash layer.
- spi-nor core addition.

Testing:
$ git clone git://git.denx.de/u-boot-spi.git
$ cd u-boot-spi
$ git checkout -b spi-nor-tune origin/next-spi-nor-tune

thanks!
