Icenowy Zheng 3993ba71f7 anlogic: fix Makefile.inc
During the addition of DRAM inferring support, the installation of
eagle_bb.v is accidentally removed.

Fix this issue.

Icenowy Zheng 7854d5ba21 anlogic: fix dbits of Anlogic Eagle DRAM16X4
The dbits of DRAM16X4 is wrong set to 2, which leads to waste of DRAM
bits.

Fix the dbits number in the RAM configuration.

Icenowy Zheng d53a2bd1d3 anlogic: add support for Eagle Distributed RAM
The MSLICEs on the Eagle series of FPGA can be configured as Distributed
RAM.

Enable to synthesis to DRAM.

As the Anlogic software suite doesn't support any 'bx to exist in the
initializtion data of DRAM, do not enable the initialization support of
the inferred DRAM.

Icenowy Zheng 634d7d1c14 Revert "Leave only real black box cells"
This reverts commit 43030db5ff.

For a synthesis tool, generating EG_LOGIC cells are a good choice, as
they can be furtherly optimized when PnR, although sometimes EG_LOGIC is
not as blackbox as EG_PHY cells (because the latter is more close to the
hardware implementation).
