 * GEnesis registers. The GEnesis chip has a 256-byte I/O window

 * divided into 128-byte blocks. The first 128 bytes of the I/O
 * window represent the first block, which is permanently mapped
 * at the start of the window. The other 127 blocks can be mapped
 * to the second 128 bytes of the I/O window by setting the desired

 * blocks are actually used. Most registers are 32 bits wide, but

 * Compute offset of port-specific register. Since there are two
 * ports, there are two of some GEnesis modules (e.g. two sets of
 * DMA queues, two sets of FIFO control registers, etc...). Normally,
 * the block for port 0 is at offset 0x0 and the block for port 1 is
 * at offset 0x80 (i.e. the next page over). However for the transmit
 * BMUs and RAMbuffers, there are two blocks for each port: one for
 * the sync transmit queue and one for the async queue (which we don't
 * use). However instead of ordering them like this:
 * TX sync 1 / TX sync 2 / TX async 1 / TX async 2
 * SysKonnect has instead ordered them like this:
 * TX sync 1 / TX async 1 / TX sync 2 / TX async 2
 * This means that when referencing the TX BMU and RAMbuffer registers,
 * we have to double the block offset (0x80 * 2) in order to reach the
 * second queue. This prevents us from using the same formula
 * (sk_port * 0x80) to compute the offsets for all of the port-specific
 * blocks: we need an extra offset for the BMU and RAMbuffer registers.
 * The simplest thing is to provide an extra argument to these macros:
 * the 'skip' parameter. The 'skip' value is the number of extra pages
 * for skip when computing the port0/port1 offsets. For most registers,
 * the skip value is 0; for the BMU and RAMbuffer registers, it's 1.
