7c21795304e6ec79ed8c35873c4419a6342eb1e3 mem: Add a helper function to get a word of variable length
There are many devices that need to handle reads/writes of different
word sizes. A common pattern is a switch statement that check for the
size of a packet and then calls the corresponding
Packet::(get|set)<uintXX_t> methods. Simplify this by implementing
Packet::(get|set)UintX helper functions.
The getter reads a word of the size specified in the packet and the
specified endianness. The word is then zero-extended to 64
bits. Conversely, the setter truncates the word down to the size
required in the packet and then byte-swaps it to the desired
endianness.
