This was include in commits from lnls-bpm/bpm-gw@09f35bd8f7 to
lnls-bpm/bpm-gw@3c537b769f

Now, almost all (with the exception of the dev_io.c which
will be fixed soon) specific code to a board is
located inside include/board/<board_name> and
src/board/<board_name>

As LLIO is build as a library, we use
the new header file location

This is needed as we use a custom mapping between
board/bpm and the bpm_id used to spawn EPICS IOC
processes.

This is a first setp into modularizing the source code into
independent components. We would like to move as much as
possible functionality into independent libraries (src/libs).

We've changed the base address name and did not reflect these
changes for the ML605 platform.

It's more flexible to use a structure for these addresses.
So, we can use different addresses for different
SMIO instances.

We don't use BAR4 specifier for all MACROS. Just for the
ones that are the base address of the SMIOs.

As we are going to use a new SMIO specifier, we update the
old ML605 macro definitions here.

As of now, we don't have a way of checking which
channel is tha valid one. So, we hardcode this limit
in software, for now.

This is a quick fix for github issue #21.

As we need to switch between BARs, we fake our real
addresses by concatenating the BAR number in the 4 MSB.
In this way, the PCIe LLIO can differentiate between BARs
ans select the correct one

New boards can be added by creating a new
file under hal/boards/ and referencing its
memory layout in hal/include/mem_layout/
