Use the generic UART driver-private data pointer, rather than
embedding the generic UART within the 16550 UART structure.

[uart] Allow for the existence of non-16550 UARTs2025-06-20T11:52:04+00:00Michael Brown2025-06-17T13:28:18+00:00urn:sha1:6c8fb4b89d49c40339fe61b7ec549d90f1ce9480
Remove the assumption that all platforms use a fixed number of 16550
UARTs identifiable by a simple numeric index. Create an abstraction
allowing for dynamic instantiation and registration of any number of
arbitrary UART models.
The common case of the serial console on x86 uses a single fixed UART
specified at compile time. Avoid unnecessarily dragging in the
dynamic instantiation code in this use case by allowing COMCONSOLE to
refer to a single static UART object representing the relevant port.
When selecting a UART by command-line argument (as used in the
"gdbstub serial <port>" command), allow the UART to be specified as
either a numeric index (to retain backwards compatiblity) or a
case-insensitive port name such as "COM2".

[build] Constrain PHYS_CODE() and REAL_CODE() to use i386 registers2025-05-07T22:03:02+00:00Michael Brown2025-05-07T21:57:40+00:00urn:sha1:e8a6c2657163af1255d1b1ccff3d19c45b0a6182
Inline assembly using PHYS_CODE() or REAL_CODE() must use the "R"
constraint rather than the "r" constraint to ensure that the compiler
chooses registers that will be valid for the 32-bit or 16-bit assembly
code fragment.

Remove the intermediate concept of a user pointer from real address
conversion, leaving real_to_virt() as the directly implemented
function.

[uaccess] Remove redundant memcpy_user() and related string functions2025-04-20T22:00:13+00:00Michael Brown2025-04-20T17:29:48+00:00urn:sha1:89fe7886897be76ed902317e311d60ae654057aa
The memcpy_user(), memmove_user(), memcmp_user(), memset_user(), and
strlen_user() functions are now just straightforward wrappers around
the corresponding standard library functions.
Remove these redundant wrappers.
