[U-Boot] [PATCH v4 18/36] sf: ramtron: Add support for separate flash driver
by Jagannadha Sutradharudu Teki 24 Sep '13

24 Sep '13

Compared to other spi flashes, ramtron has a different probing and implementation on flash ops, hence moved ramtron probe code into ramtron driver.

[U-Boot] [PATCH v4 13/36] sf: probe: Add support to clear flash BP# bits
by Jagannadha Sutradharudu Teki 24 Sep '13

24 Sep '13

Few of the flashes(Atmel, Macronix and SST) require to clear BP# bits in flash power ups. So clear these BP# bits at probe time, so-that the flash is ready for user operations.

[U-Boot] [PATCH v4 12/36] sf: probe: Add support for SST_WP
by Jagannadha Sutradharudu Teki 24 Sep '13

24 Sep '13

Most of the SST flashes needs to write up using SST_WP, AAI Word Program, so added a flag param on spi_flash_params table. SST flashes, which supports SST_WP need to use a WP write sst_write_wp instead of common flash write.
