Hm. In the spirit of language ecumenics and comparison, I translate your
example to Ada, below. I try to use your identifiers as such, although
Ada convention would use Title_Style capitalisation.

-- The "dr" register type:
type dr_t is record
data : interfaces.unsigned_8;
fe : boolean;
pe : boolean;
be : boolean;
oe : boolean;
end record
with volatile, size => 32, bit_order => system.low_order_first;
--
-- I would not usually make the _type_ volatile, because
-- that could slow down operations on all variables of
-- the type, even if they are not mapped to control
-- registers. I would mark as volatile (or atomic) only
-- the variables mapped to registers.
-- Its structure on the bit level (I could also have said
-- just "pack", but this is safer and more explicit):
for dr_t use record
data at 0 range 0 .. 7;
fe at 0 range 8 .. 8;
pe at 0 range 9 .. 9;
be at 0 range 10 .. 10;
oe at 0 range 11 .. 11;
end record
-- The "lchr" register type(s):
type par_t is (NONE, ODD, EVEN);
for par_t use (NONE => 0, ODD => 1, EVEN => 3);
type stop_t is (S1, S2);
-- Or it could be:
-- type stop_t is range 1 .. 2;
-- for compilers that support offset encoding.
type wlen_t is (B5, B6, B7, B8);
-- Or it could be:
-- type wlen_t is range 5 .. 8;
-- for compilers that support offset encoding.
type lcrh_t is record
brk : boolean;
par : par_t;
stop : stop_t;
fen : boolean;
wlen : wlen_t;
sps : boolean;
end record
with volatile, size => 32, bit_order => system.low_order_first;
for lchr_t use record
brk at 0 range 0 .. 0;
par at 0 range 1 .. 2;
stop at 0 range 3 .. 3;
fen at 0 range 4 .. 4;
wlen at 0 range 5 .. 6;
sps at 0 range 7 .. 7;
end record;
-- The combination:
type UartRegs is record
dr : dr_t;
lchr : lchr_t;
end record
with pack;
-- The "pack" aspect corresponds to your "packed".

uart2 : constant UartRegs_ref :=
to_pointer (to_address (16#4000_2000#));

In summary, the only semantic difference is that the Ada "volatile"
aspect cannot be separated into "in" and "out" parts, as in your language.
Syntactically Ada needs more lines, because enumerations and sub-records
must be defined as types. Does your language use "structural
equivalence" for types? That is, if one register field is defined as the
enumeration (A, B, C), and another register field is also defined as the
enumeration (A, B, C), are these fields of the same type?
