test: log: Convert log_test from python to C
When rebasing this series I had to renumber all my log tests because
someone made another log test in the meantime. This involved updaing a
number in several places (C and python), and it wasn't checked by the
compiler. So I though "how hard could it be to just rewrite in C?" And
though it wasn't hard, it *was* tedious. Tests are numbered the same as
before to allow for easier review.
A note that if a test fails, everything after it will probably also fail.
This is because that test won't clean up its filters. There's no easy way
to do the cleanup, except perhaps removing all filters in a wrapper

log: Add filter flag to deny on match
Without this flag, log filters can only explicitly accept messages.
Allowing denial makes it easier to filter certain subsystems. Unlike
allow-ing filters, deny-ing filters are added to the beginning of the
filter list. This should do the Right Thing most of the time, but it's
less-universal than allowing filters to be inserted anywhere. If this
becomes a problem, then perhaps log_filter_add* should take a filter number

cmd: Add a mux command
This command lets the user list, select, and deselect mux controllers
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

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.

arm64: zynqmp: Add support for saving sha3 key to different address
By default 48B sha3 hash value is written to srcaddr which is not the best
solution in case of that you want to use data for other operations. That's
why add key_addr optional parameters which enables to write 48B sha3 hash
value to specified address.

arm64: zynqmp: Add support for encryption and decryption on data blob
This patch adds support for encryption and decryption on a given data
blob using different key sources such as userkey(KUP), device key and
PUF key. Inorder to support this a new zynqmp command(zynqmp aes) has
been introduced.
Command:
zynqmp aes srcaddr ivaddr len aesop keysrc dstaddr [keyaddr]\n"
Encrypts or decrypts blob of data at src address and puts it\n"
back to dstaddr using key and iv at keyaddr and ivaddr\n"
respectively. keysrc values specifies from which source key\n"
has to be used, it can be User/Device/PUF key. A value of 0\n"
for KUP(user key),1 for DeviceKey and 2 for PUF key. The\n"
aesop value would specify the operationwhich can be 0 for\n"
decrypt and 1 for encrypt(1) operation\n";

arm64: zynqmp: Get rid of iommus/power-domains properties for SPL DT
SPL DT contains only nodes which are contain u-boot,dm-pre-reloc property.
iommu node is not this case that's why when DT is read DTC reports some
warnings.
$ dtc -I dtb -O dts dts/dt-spl.dtb >/dev/null
<stdout>: Warning (iommus_property): /amba/spi@ff0f0000:iommus: Could not get phandle node for (cell 0)
<stdout>: Warning (iommus_property): /amba/mmc@ff160000:iommus: Could not get phandle node for (cell 0)
<stdout>: Warning (iommus_property): /amba/mmc@ff170000:iommus: Could not get phandle node for (cell 0)
SPL also has an option to remove some DT properties which are useless for
SPL to make DT even smaller.
Default DT properties are pinctrl-0 pinctrl-names interrupt-parent
interrupts which are already removed.
The patch extends this list with iommus to get rid of above warnings.
Also power-domains unused properties can be removed.

arm64: zynqmp: Enable FPGA loading from SPL
fpga bitstream needs to be listed in config node in FIT image. Only tested
option is bitstream in BIN format.
Enabling this feature increase code size by almost 4k.

arm64: zynqmp: Get rid of simple_itoa and replace it by snprintf
simple_itoa() is implemented only for !CONFIG_USE_TINY_PRINTF. Tiny printf
is normally used by SPL that's code which uses simple_itoa() has missing
reference. That's why refactor code by using on snprintf() instead of
strncpy()/strncat() combination. This change also descrease code size by
saving 24B based on buildman.

firmware: zynqmp: Swap addr_hi/low when PM_FPGA_LOAD is called
Don't know reason but in regular flow addr_hi/low are swapped in ATF. It
means when fpga load is done from EL3 there is a need to swap it for PMUFW
to load bitstream.
