LEON: added new drivers to the LEON2/LEON3 BSPs

Most drivers use the Driver Manager for device probing, they
work on AMBA-over-PCI systems if PCI is big-endian.

New APIs:

  • GPIO Library, interfaced to GRGPIO
  • GENIRQ, Generic interrupt service implementation helper

New GRLIB Drivers:

  • ACTEL 1553 RT, user interface is similar to 1553 BRM driver
  • GR1553 (1553 BC, RT and BM core)
  • AHBSTAT (AHB error status core)
  • GRADCDAC (Core interfacing to ADC/DAC hardware)
  • GRGPIO (GPIO port accessed from GPIO Library)
  • MCTRL (Memory controller settings configuration)
  • GRETH (10/100/1000 Ethernet driver using Driver manager)
  • GRPWM (Pulse Width Modulation core)
  • SPICTRL (SPI master interface)
  • GRSPW_ROUTER (SpaceWire? Router AMBA configuration interface)
  • GRCTM (SpaceCraft? on-board Time Management core)
  • SPWCUC (Time distribution over SpaceWire?)
  • GRTC (SpaceCraft? up-link Tele core)
  • GRTM (SpaceCraft? down-link Tele Metry core)

GR712RC ASIC specific interfaces:

  • GRASCS
  • CANMUX (select between OCCAN and SATCAN)
  • SATCAN
  • SLINK
  • Property mode set to 100644

Line 
1A non Driver Manager GRETH driver is located in libchip/network/greth.c. This
2version requires the driver manager.
3
4network_interface_add is used to assign IP/NETMASK and MAC address to
5GRETH interfaces dynamically according to in which order devices are
6registered. The function takes the settings from the user defined
7interface_configs[] array, defined in the project configuration.
