[U-Boot] [PATCH 1/1] mtd/spi: Support of non-jedec MRAM devices
Matt Weber
matthew.weber at rockwellcollins.com
Mon Jul 10 16:31:32 UTC 2017
This patch adds support of non-jedec MRAM devices mr25hx from Everspin.
This flash devices do not have jedec device ID and hence support for
name matching is also added as part of this series.
This patch streamlined the update of SPI flash probing function API
changes and included the following updates:
1) Updated "spi_flash_probe" (old method) and
"spi_flash_probe_bus_cs" (new method) APIs
2) Added ifdefs for CONFIG_ENV_SPI_NAME and CONFIG_SF_DEFAULT_NAME so
that addition of flash name in case of non-jedec device becomes
streamlined.
3) Used CONFIG_ENV_SPI_NAME and CONFIG_SF_DEFAULT_NAME at all possible
places except board/ files which has custom or hard coded arguments in
"spi_flash_probe" functions. In such cases, passed NULL as flash name.
