0914011310 command: Remove the cmd_tbl_t typedef
We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.

Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.

This requires quite a few header-file additions.

f042e47e8f efi_loader: Implement EFI variable handling via OP-TEE
In OP-TEE we can run EDK2's StandAloneMM on a secure partition.
StandAloneMM is responsible for the UEFI variable support. In
combination with OP-TEE and it's U-Boot supplicant, variables are
authenticated/validated in secure world and stored on an RPMB partition.

So let's add a new config option in U-Boot implementing the necessary
calls to OP-TEE for the variable management.

714497e327 efi_loader: round the memory area in efi_add_memory_map()
Virtually all callers of this function do the rounding on their own.
Some do it right, some don't. Instead of doing this in each caller,
do the rounding in efi_add_memory_map(). Change the size parameter
to bytes instead of pages and remove aligning and size calculation in
all callers.

There is no more need to make the original efi_add_memory_map() (which
takes pages as size) available outside the module. Thus rename it to
efi_add_memory_map_pg() and make it static to prevent further misuse
outside the module.

fdf0819afb rsa: fix alignment issue when getting public exponent
To fill the exponent field of the rsa_public_key struct, rsa_mod_exp_sw
did a cast to uint64_t of the key_prop->public_exponent field.
But that alignment is not guaranteed in all cases.

This came to light when in my spl-fit-signature the key-name exceeded
a certain length and with it the verification then started failing.
(naming it "integrity" worked fine, "integrity-uboot" failed)

key_prop.public_exponent itself is actually a void-pointer, fdt_getprop()
also just returns such a void-pointer and inside the devicetree the 64bit
exponent is represented as 2 32bit numbers, so assuming a 64bit alignment
can lead to false reads.

So just use the already existing rsa_convert_big_endian() to do the actual
conversion from the dt's big-endian to the needed uint64 value.

necessary only when CONFIG_(SPL_TPL_)_FIT_SIGNATURE is enabled.

080019b86c make env_entry::callback conditional on !CONFIG_SPL_BUILD
The callback member of struct env_entry is always NULL for an SPL
build. Removing it thus saves a bit of run-time memory in the
SPL (when CONFIG_SPL_ENV_SUPPORT=y) since struct env_entry is embedded
in struct env_entry_node - i.e. about 2KB for the normal case of
512+change hash table entries.

Two small fixups are needed for this, all other references to the
callback member are already under !CONFIG_SPL_BUILD: Don't initialize
.callback in set_flags() - hsearch_r doesn't use that value
anyway. And make env_callback_init() initialize ->callback to NULL for
a new entry instead of relying on an unused or deleted entry having
NULL in ->callback.

4540dabdca efi_loader: image_loader: support image authentication
With this commit, image validation can be enforced, as UEFI specification
section 32.5 describes, if CONFIG_EFI_SECURE_BOOT is enabled.

Currently we support
* authentication based on db and dbx,
  so dbx-validated image will always be rejected.
* following signature types:
    EFI_CERT_SHA256_GUID (SHA256 digest for unsigned images)
    EFI_CERT_X509_GUID (x509 certificate for signed images)
Timestamp-based certificate revocation is not supported here.

Internally, authentication data is stored in one of certificates tables
of PE image (See efi_image_parse()) and will be verified by
efi_image_authenticate() before loading a given image.

It seems that UEFI specification defines the verification process
in a bit ambiguous way. I tried to implement it as closely to as
EDK2 does.

In the current implementation of FIT_SIGNATURE, five parameters for

(See rsa-mod-exp.h and uImage.FIT/signature.txt)
This is a result of considering relatively limited computer power

In this patch, added is a function, rsa_gen_key_prop(), which will

Currently, if GetMemoryMap API returns EFI_BUFFER_TOO_SMALL, it doesn't
set valid values to other parameters, descriptor_size and
descriptor_version, except memory_map_size.
Some efi applications, however, may use those value; in particular,
xen uses descriptor_size to calculate a size of buffer to be allocated.

While UEFI specification is ambiguous in this point, it would be better
to address this issue proactively to maximize the compatibility with
existing efi applications.

With this patch, for example, xen.efi (and hence linux kernel) can be
started via bootefi without modification.

479ab6c17e efi_selftest: add selftests for loadfile2 used to load initramfs
Provide a unit test loading an initial ramdisk using the
EFI_LOAD_FILE2_PROTOCOL. The test is only executed on request.

An example usage - given a file image with a file system in partition 1
holding file initrd - is:

* Configure the sandbox with

  CONFIG_EFI_SELFTEST=y
  CONFIG_EFI_LOAD_FILE2_INITRD=y
  CONFIG_EFI_INITRD_FILESPEC="host 0:1 initrd"

* Run ./u-boot and execute

    host bind 0 image
    setenv efi_selftest load initrd
    bootefi selftest

This would provide a test output like:

    Testing EFI API implementation

    Selected test: 'load initrd'

    Setting up 'load initrd'
    Setting up 'load initrd' succeeded

    Executing 'load initrd'
    Loaded 12378613 bytes

ec80b4735a efi_loader: Implement FileLoad2 for initramfs loading
Following kernel's proposal for an arch-agnostic initrd loading
mechanism [1] let's implement the U-boot counterpart.
This new approach has a number of advantages compared to what we did up
to now. The file is loaded into memory only when requested limiting the
area of TOCTOU attacks. Users will be allowed to place the initramfs
file on any u-boot accessible partition instead of just the ESP one.
Finally this is an attempt of a generic interface across architectures
in the linux kernel so it makes sense to support that.

The file location is intentionally only supported as a config option
argument(CONFIG_EFI_INITRD_FILESPEC), in an effort to enhance security.
Although U-boot is not responsible for verifying the integrity of the
initramfs, we can enhance the offered security by only accepting a
built-in option, which will be naturally verified by UEFI Secure Boot.
This can easily change in the future if needed and configure that via ENV
or UEFI variable.

In upstream libfdt, 6dcb8ba4 "libfdt: Add helpers for accessing
unaligned words" introduced changes to support unaligned reads for ARM
platforms and 11738cf01f15 "libfdt: Don't use memcpy to handle unaligned
reads on ARM" improved the performance of these helpers.

In practice however, this only occurs when the user has forced the
device tree to be placed in memory in a non-aligned way, which in turn
violates both our rules and the Linux Kernel rules for how things must
reside in memory to function.

This "in practice" part is important as handling these other cases adds
visible (1 second or more) delay to boot in what would be considered the
fast path of the code.

When the GetInfo() method of the EFI_FILE_PROTOCOL is called to retrieve
the file system info we claim that the volume is read only and has no free
space. This leads to failures in programs that check this information
before writing to the volume like SCT's InstallSct.efi.

Currently there is no function to determine these parameters in U-Boot. So
let's return optimistic values:

Return that the volume is writable.

Return the volume size as free space.

8876e1bc88 efi_loader: imply USB_KEYBOARD_FN_KEYS
UEFI applications like GRUB and SCT assume that function keys are enabled
on the keyboard.

Let EFI_LOADER imply USB_KEYBOARD_FN_KEYS.

77dd7c6854 x86: timer: use a timer base of 0
On x86 platforms the timer is reset to 0 when the SoC is reset. Having
this as the timer base is useful since it provides an indication of how
long it takes before U-Boot is running.

When U-Boot sets the timer base to something else, time is lost and we
no-longer have an accurate account of the time since reset. This
particularly affects bootstage.

Change the default to not read the timer base, leaving it at 0. Add an
option for when U-Boot is the secondary bootloader.

d721001fd6 net: Move the checksum functions to lib/
These functions are used by code outside the network support, so move them
to lib/ to be more accessible.

Without this, the functions are only accessible in SPL/TPL only if
CONFIG_SPL/TPL_NET are defined. Many boards do not enable those option but
still want to do checksums in this format.

Fix up a few code-style nits while we are here.

3c10dc95bd binman: Add a library to access binman entries
SPL and TPL can access information about binman entries using link-time
symbols but this is not available in U-Boot proper. Of course it could be
made available, but the intention is to just read the device tree.

Add support for this, so that U-Boot can locate entries.

fb8977c5be net: Always build the string_to_enetaddr() helper
Part of the env cleanup moved this out of the environment code and into
the net code. However, this helper is sometimes needed even when the net
stack isn't included.

Move the helper to lib/net_utils.c like it's similarly-purposed
string_to_ip(). Also rename the moved function to similar naming.
