dw/mw and the sister commands take virtual address as input for display
or modify. Option "-p" to the command signifies the address input is
physical, and the address translation is handled by the command.
Newly added option is available with WITH_KERNEL_VM, usage as follows
] dw 0xffffffff05100000 4
0xffffffff05100000: 0000dead
] dw 0x5100000 4 -p
0xffffffff05100000: 0000dead

Accessing un-mapped address/address-range results in data abort. Ensure
the address and all the pages in the requested range are mapped. Mapping
is checked at page size, also adjusts the stop address to the nearest valid
address mapped.
GCC 12 seems to be much more aggressive about warnings about any
dereferences near 0. For this particular piece of code, which is
explicitly trying to force a fault by touching address 1, simply disable
the warning around the block of code.
Some of the structures, notably 'cmd', in the lib console stuff are a
little too generically named and have collided with some other code
so prefix the names a bit more cleanly with console_
The change is largely mechanical, and folks with out of tree code can
easily switch by renaming:
cmd -> console_cmd
cmd_args -> console_cmd_args
cmd_block -> console_cmd_block
console_cmd -> console_cmd_func
Apologies if this breaks you but it should be pretty easy to fix.
TL;DR most uses of lib/console.h -> lk/console_cmd.h
Move the part that lets a piece of code somewhere in the system to
define a console command from the actual lib/console api to start an
instance of the console. Move in almost every place the user of the
console command definition to the new header, lk/console_cmd.h which is
always in the include path.
Also remove most uses of testing for WITH_LIB_CONSOLE since you can
almost always just safely define it and then let the linker remove it.
Almost nothing changes here except moving braces to the same line as the
function declaration. Everything else is largely whitespace changes and
a few dangling files with tab indents.
See scripts/codestyle
Move implementation to stdio.c to sit next to the other
stdio definitions that use the debug output functions. Keep
the declaration of it, though, in printf.h to sit next to
sprintf, etc.
Don't include printf.h directly in other places, rely on stdio.h
to properly pull in these functions.

-Remove top level DEBUG=<N> define
-Rename DEBUGLEVEL to LK_DEBUGLEVEL to be clear.
-Fix the places that used DEBUGLEVEL and the few spots that #ifdef
on DEBUG.
