Cover letter [U-Boot] [PATCH 0/3] Serial Flash: call spi_flash_free more coherently
Quoted 16 lines · 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

I have sent this series 4 months ago and while it is according to patchwork under review I have not received any feedback yet.

That would be nice if this goes into the next merge window since they have been floating around for 4 months now.

Thanks

Valentin
