The BSP backend - provides the glue to the specific bus for the target hardware. It has - been tested with Coldfire processors, and the PC. These targets have - completely different bus, byte order and interrupt structures. - - An example BSP backend is provided in the pci386 BSP. - - The BSP provides the following functions: - - cs8900_io_set_reg - cs8900_io_get_reg - cs8900_mem_set_reg - cs8900_mem_get_reg - cs8900_put_data_block - cs8900_get_data_block - cs8900_tx_load - cs8900_attach_interrupt - cs8900_detach_interrupt - - The header file provides documentation for these functions. There - are four types of functions. - - The I/O set/get functions access the CS8900 I/O registers via the - I/O Mode. For example on a PC with an ISA bus you would use the - IA32 in/out port instructions. The cs8900_device structure passed - to these functions provide these functions with the I/O base - address. The BSP must provide these functions. - - The Memory set/get functions access the CS8900 internal registers - and frame buffers directly from a 4K byte block of host memory. - Memory mode provides a faster access to the CS8900. The cs8900_device - structure passed to these functions provides the memory base - address. The BSP needs to provide these functions but they do not - need to be implemented if the mem_base field is set to 0. The - driver will use I/O mode only. - - The Block transfer functions are used to read or write a block - of memory from the CS8900. This saves the driver making a number - of small calls. The BSP driver must know if I/O or Memory mode - can be used. - - The final group of functions is to handle interrupts. The BSP - must take care of save and restoring any interrupt state - information. - - The BSP declares a 'cs8900_device' structure for each device being - attached to the networking stack. It also creates a - 'struct rtems_bsdnet_ifconfig' which is used to attach the interface - to the networking stack. The following code declares the BSD config: - - static cs8900_device cs8900; - - static struct rtems_bsdnet_ifconfig cs8900_ifconfig = - { - "cs0", - cs8900_driver_attach, - NULL, - NULL, - NULL, - NULL, - 0, - 0, - 0, - 0, - 0, - 0, - 0, - 0 - }; - - The device linked to the BSD config structure with: - - cs8900_ifconfig.drv_ctrl = &cs8900; - - If you have a specific hardware address you should point the BSD - config structure to that address. If you do not the driver will read - the MAC address from the CS8900. This assumes the CS8900 has read - the address from an external EEPROM or has been setup by a BIOS or - boot monitor. For EEPROM less you need to supply the MAC address. - - Set the I/O and Memory base addresses. If the Memory base address - is 0 the driver will use I/O mode only. A typical initialisation - looks like: - - printf ("RTEMS BSD Network initialisation.\n"); - rtems_bsdnet_initialize_network (); - - #define ETHERNET_IO_BASE 0x300 - #define ETHERNET_MEM_BASE 0 - #define ETHERNET_IRQ_LEVEL 0 - - cs8900_device *cs = &cs8900; - - memset (cs, 0, sizeof (cs8900_device)); - - cs->dev = 0; - cs->io_base = ETHERNET_IO_BASE; - cs->mem_base = ETHERNET_MEM_BASE; - cs->irq_level = ETHERNET_IRQ_LEVEL; - cs->rx_queue_size = 30; - - cs8900_ifconfig.drv_ctrl = &cs8900; - - printf ("CS8900 initialisation\n"); - - rtems_bsdnet_attach (&cs8900_ifconfig); - - flags = IFF_UP; - if (rtems_bsdnet_ifconfig (cs8900_ifconfig.name, - SIOCSIFFLAGS, - &flags) < 0) - { - printf ("error: can't bring up %s: %s\n", - cs8900_ifconfig.name, strerror (errno)); - return; - } - - rtems_bsdnet_do_bootp_and_rootfs (); - - The IRQ level is the one documented in the CS8900 datasheet and below - in the CS8900 device structure. You need to map your target IRQ to the - CS8900 in the BSP driver. - - */ - -#if !defined(_CS8900_H_) -#define _CS8900_H_ - -#include <rtems.h> -#include <rtems/error.h> -#include <rtems/rtems_bsdnet.h> - -#include <sys/param.h> -#include <sys/mbuf.h> -#include <sys/socket.h> -#include <sys/sockio.h> - -#include <net/if.h> - -#include <netinet/in.h> -#include <netinet/if_ether.h> - -/* #include <target.h> what does this provide? joel to chris */ - -#define ET_MINLEN 60 - -/* - * CS8900 device register definitions - */ - -/* - * Crystal ESIA product id. - */ - -#define CS8900_ESIA_ID (0x630e) - -/* - * IO Registers. - */ - -#define CS8900_IO_RX_TX_DATA_PORT0 (0x0000) -#define CS8900_IO_TX_TX_DATA_PORT1 (0x0002) -#define CS8900_IO_TxCMD (0x0004) -#define CS8900_IO_TxLength (0x0006) -#define CS8900_IO_ISQ (0x0008) -#define CS8900_IO_PACKET_PAGE_PTR (0x000a) -#define CS8900_IO_PP_DATA_PORT0 (0x000c) -#define CS8900_IO_PP_DATA_PORT1 (0x000e) - -/* - * Packet Page Registers. - */ - -/* - * Bus Interface Registers. - */ - -#define CS8900_PP_PROD_ID (0x0000) -#define CS8900_PP_IO_BASE (0x0020) -#define CS8900_PP_INT (0x0022) -#define CS8900_PP_DMA_CHANNEL (0x0024) -#define CS8900_PP_DMA_SOF (0x0026) -#define CS8900_PP_DMA_FRM_CNT (0x0028) -#define CS8900_PP_DMA_RX_BCNT (0x002a) -#define CS8900_PP_MEM_BASE (0x002c) -#define CS8900_PP_BPROM_BASE (0x0030) -#define CS8900_PP_BPROM_AMASK (0x0034) -#define CS8900_PP_EEPROM_CMD (0x0040) -#define CS8900_PP_EEPROM_DATA (0x0042) -#define CS8900_PP_RX_FRAME_BCNT (0x0050) - -/* - * Configuration and Control Registers. - */ - -#define CS8900_PP_RxCFG (0x0102) -#define CS8900_PP_RxCTL (0x0104) -#define CS8900_PP_TxCFG (0x0106) -#define CS8900_PP_TxCMD_READ (0x0108) -#define CS8900_PP_BufCFG (0x010a) -#define CS8900_PP_LineCFG (0x0112) -#define CS8900_PP_SelfCTL (0x0114) -#define CS8900_PP_BusCTL (0x0116) -#define CS8900_PP_TestCTL (0x0118) - -/* - * Status and Event Registers. - */ - -#define CS8900_PP_ISQ (0x0120) -#define CS8900_PP_RxEvent (0x0124) -#define CS8900_PP_TxEvent (0x0128) -#define CS8900_PP_BufEvent (0x012c) -#define CS8900_PP_RxMISS (0x0130) -#define CS8900_PP_TxCol (0x0132) -#define CS8900_PP_LineST (0x0134) -#define CS8900_PP_SelfST (0x0136) -#define CS8900_PP_BusST (0x0138) -#define CS8900_PP_TDR (0x013c) - -/* - * Initiate Transmit Registers. - */ - -#define CS8900_PP_TxCMD (0x0144) -#define CS8900_PP_TxLength (0x0146) - -/* - * Address Filter Registers. - */ - -#define CS8900_PP_LAF (0x0150) -#define CS8900_PP_IA (0x0158) - -/* - * Frame Location. - */ - -#define CS8900_PP_RxStatus (0x0400) -#define CS8900_PP_RxLength (0x0402) -#define CS8900_PP_RxFrameLoc (0x0404) -#define CS8900_PP_TxFrameLoc (0x0a00) - -/* - * Bit Definitions of Registers. - */ - -/* - * IO Packet Page Pointer. - */ - -#define CS8900_PPP_AUTO_INCREMENT (0x8000) - -/* - * Reg 3.
