I have been reading this thread (which has wandered all over the place) because
I'm interested in language design for embedded systems. One nice thing about
no longer being "gainfully employed" is that one has time to experiment. I
have developed my own programming language for implementing operating systems
and drivers. It is a front-end to LLVM and is pretty complete.
<shameless-plug>
Sources for the compiler (written in itself) at
https://github.com/bagel99/esl
Sources for lots of drivers and network stuff at

</shameless-plug>
Here's how I approached the device driver question: at what hardware address is
the device? First defining the device register layout:
type UartRegs:
{ dr:
{ data: _uint8; // .00-07
fe: boolean; // .08
pe: boolean; // .09
be: boolean; // .10
oe: boolean; // .11
}: packed, lsb, bits(32), in, out;
lcrh:
{ brk: boolean; // .00
par: (NONE,ODD,_,EVEN); // .01-02
stop: (S1,S2); // .03
fen: boolean; // .04
wlen: (B5,B6,B7,B8); // .05-06
sps: boolean; // .07
}: packed, lsb, bits(32), out;
...
};
// packed - squeeze all the bits into the smallest width
// lsb - the fields start at the least significant bit
// bits[32] - extend the size to 32 bits with zeros
// out - like volatile, but side effects only happen on writes
// in - like volatile, but side effects only happon on reads
Then define the hardware address one of three ways:
var uart0: UartRegs: external(0x4000_0000);
// uart0 address is 0x40000000
var uart1: UartRegs: external("UART1");
// linker supplies address constant UART1=xxx
const uart2: @UartRegs = 0x4000_2000;
// define a constant pointer to the device
And assigning device bits without using masks:
uart0.lcrh = {.brk=false, .par=NONE, .stop=S1, .wlen=B8 };
// fields not specified take the zero value
