dm: Don't allow U_BOOT_DEVICE() when of-platdata is used
With of-platdata, the devicetree is supposed to specify all the devices
in the system. So far this hasn't really mattered since of-platdata still
works correctly.
However, new of-platdata features rely on numbering the devices in a
particular order so that they can be referenced by a single integer. It is
tricky to implement this efficiently when other devices are present in the
build.
To address this, disable use of U_BOOT_DEVICE() when of-platdata is
enabled. This seems acceptable as it is not supposed to be used at all,
except in SPL/TPL, where of-platdata is the recommended approach.

Since we don't know the struct udevice pointer until it is allocated in

annoying since it requires that SPL's data is writable and adds a small

cmd: Add a mux command

introduced with the mux framework on the fly. It has 3 subcommands:
list, select, and deselect.
List: Lists all the mux present on the system. The muxes are listed for
each chip. The chip is identified by its device name. Each chip can have
a number of mux controllers. Each is listed in sequence and is assigned
a sequential ID based on its position in the mux chip. It lists details
like ID, whether the mux is currently selected or not, the current
state, the idle state, and the number of states.
A sample output would look something like:
=> mux list
a-mux-controller:
ID Selected Current State Idle State Num States
0 no unknown as-is 0x4
1 no 0x2 0x2 0x10
2 no 0x73 0x73 0x100
another-mux-controller:
ID Selected Current State Idle State Num States
0 no 0x1 0x1 0x4
1 no 0x2 0x2 0x4
Select: Selects a given mux and puts it in the specified state. This
subcommand takes 3 arguments: mux chip, mux ID, state to set
the mux in. The arguments mux chip and mux ID are used to identify which
mux needs to be selected, and then it is selected to the given state.
The mux needs to be deselected before it can be selected again in
another state. The state should be a hexadecimal number.
For example:
=> mux list
a-mux-controller:
ID Selected Current State Idle State Num States
0 no 0x1 0x1 0x4
1 no 0x1 0x1 0x4
=> mux select a-mux-controller 0 0x3
=> mux list
a-mux-controller:
ID Selected Current State Idle State Num States
0 yes 0x3 0x1 0x4
1 no 0x1 0x1 0x4
Deselect: Deselects a given mux and puts it in its idle state. This
subcommand takes 2 arguments: the mux chip and mux ID to identify which
mux needs to be deselected. So in the above example, we can deselect mux
0 using:
=> mux deselect a-mux-controller 0
=> mux list
a-mux-controller:
ID Selected Current State Idle State Num States
0 no 0x1 0x1 0x4
1 no 0x1 0x1 0x4

efi_loader: Disable devices before handing over control
U-Boot Driver Model is supposed to remove devices with either
DM_REMOVE_ACTIVE_DMA or DM_REMOVE_OS_PREPARE flags set, before exiting.
Our bootm command does that by explicitly calling calling
"dm_remove_devices_flags(DM_REMOVE_ACTIVE_ALL);" and we also disable any
USB devices.
The EFI equivalent is doing none of those at the moment. As a result
probing an fTPM driver now renders it unusable in Linux. During our
(*probe) callback we open a session with OP-TEE, which is supposed to
close with our (*remove) callback. Since the (*remove) is never called,
once we boot into Linux and try to probe the device again we are getting
a busy error response. Moreover all uclass (*preremove) functions won't
run.
So let's fix this by mimicking what bootm does and disconnect devices
when efi_exit_boot_services() is called.
