This new initialization code supports the 57711 HW. It also supports the emulation and FPGA for the 57711 and 57710 initializations values (very small amount of code which is very helpful in the lab - less than 30 lines). The initialization is done via DMAE after the DMAE block is ready - before it is ready, some of the initialization is done via PCI configuration transactions (referred to as indirect write). A mutex to protect the DMAE from being overlapped was added. There are few new registers which needs to be initialized by SW - the full comment for those registers is added to the register file. A place holder for the 57711 (referred to as E1H) microcode was added- the microcode itself is too big and it is split over the following 4 patches Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
