bank: add re to CSRStorage
...
being able to know when a register is updated is useful in many cases and avoid having to handle another register for that.
re is asserted when the the last CSR of the Compound is written. Software must also write Compound in the right order.

mila: add clk_domain support
...
an AsyncFIFO is inserted when clk_domain is not "sys" to enable capture from another clock domain.
sys_clk frequency need to be greater than clk_domain clock.
future possible improvement: automatic insertion of a converter when clk_domain frequency is
greater than sys_clk.

CRCEngine implements a generic and optimized CRC LFSR. It will enable generation of CRC generators and checkers.
CRC32 is an implementation of IEEE 802.3 CRC using the CRCEngine.
CRC32Inserter and CRC32Checker have been tested on an ethernet MAC.

targets: add simple design (vendor agnostic and usable on all platforms with UART pins).
...
Designing a SoC with Migen is easy, but we have to provide a very simple design that can
be used on all boards with only 1 clock and 2 UARTs pins defined. This will encourage the
newcomer to invest time in Migen/MiSoC and see its real potential.
