Changeset 289 for soft/giet_vm/giet_drivers/spi_driver.c

Modifications on GIET-VM IOC driver:

• Introducing new layer on the IOC driver. Every call to ioc_read, ioc_write, ioc_get_block_size or ioc_init

functions will call the specific driver of the used IOC
controller. Supported IOC controllers are (for now) :

1. BDV (Soclib Block Device)
2. HBA
3. SPI (SDCARD - SPI controller)

• All functions of IOC controllers drivers respect the same interface.

• To specify the used IOC controller of the platform, a subtype field has been introduced on the map.xml file. This subtype field must be declared on the IOC periph instantiation. Available subtypes (for now) : BDV, HBA or SPI.
