[U-Boot] [PATCH 0/3] Serial Flash: call spi_flash_free more coherently

[Valentin Longchamp]

Some board require spi_flash_free to be called after all the accesses,
in order, for instance, to restore the pin multiplexing configuration in
the case where the SPI pins are multiplexed.

This patch series tries to enhance this. Patch 1 adds spi_flash_free
calls to env_sf so that the SPI interface is always "cleaned up" after
the env read/writes. Patch 2 adds a 'sf release' command that implicitly
calls spi_flash_free and is thus the pendant of 'sf probe'. Patch 3 uses
the 'sf command' for the km_arm board scripts.


Valentin Longchamp (3):
  env_sf: generalize call to spi_flash_free after accesses
  cmd_sf: add 'release' command
  km_arm: call 'sf release' in the newenv and update scripts
