Subject: [PATCH 10/12] spi_flash: disable functions not required or not
|
|
supported
|
|
|
|
Various cache utility functions are neither required nor can they be supported by the means of RIOT. For example, it is not possible to change the priority of a thread. They have to be therefore disabled in RIOT.
