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