* Ethernet status, per interface.
|
|
*
|
|
* hardware addresses/sizes to know (all KVA):
|
|
* sc_iobase = base of chip's 24 bit address space
|
|
* sc_maddr = base address of chip RAM as stored in ie_base of iscp
|
|
* sc_msize = size of chip's RAM
|
|
* sc_reg = address of card dependent registers
|
|
*
|
|
* the chip uses two types of pointers: 16 bit and 24 bit
|
|
* 16 bit pointers are offsets from sc_maddr/ie_base
|
|
* KVA(16 bit offset) = offset + sc_maddr
|
|
* 24 bit pointers are offset from sc_iobase in KVA
|
|
* KVA(24 bit address) = address + sc_iobase
|
|
*
|
|
* on the vme/multibus we have the page map to control where ram appears
|
|
* in the address space. we choose to have RAM start at 0 in the
|
|
* 24 bit address space. this means that sc_iobase == sc_maddr!
|
|
* to get the phyiscal address of the board's RAM you must take the
|
|
* top 12 bits of the physical address of the register address
|
|
* and or in the 4 bits from the status word as bits 17-20 (remember that
|
|
* the board ignores the chip's top 4 address lines).
|
|
* For example:
|
|
* if the register is @ 0xffe88000, then the top 12 bits are 0xffe00000.
|
|
* to get the 4 bits from the the status word just do status & IEVME_HADDR.
|
|
* suppose the value is "4". Then just shift it left 16 bits to get
|
|
* it into bits 17-20 (e.g. 0x40000). Then or it to get the
|
|
* address of RAM (in our example: 0xffe40000). see the attach routine!
|
|
*
|
|
* on the onboard ie interface the 24 bit address space is hardwired
|
|
* to be 0xff000000 -> 0xffffffff of KVA. this means that sc_iobase
|
|
* will be 0xff000000. sc_maddr will be where ever we allocate RAM
|
|
* in KVA. note that since the SCP is at a fixed address it means
|
|
* that we have to allocate a fixed KVA for the SCP.
