aed6480fad drivers: clk: Adjust temp var data type to properly match that of struct clk_ops
In commit 5c5992cb90 ("clk: Add debugging for return values"), a
temporary storage variable was added around the ops->get_rate() call
inside clk_get_rate(), so that the result could be passed through
log_ret.

This temporary variable was declared as an int, yet when we look in
struct clk_ops, we can see this needs to be a ulong:
ulong (*get_rate)(struct clk *clk);

This was resulting in a signed to unsigned casting error on our
builds, where a clock value of 0xABCDABCD was being incorrectly cast
to 0xFFFFFFFFABCDABCD.

21c84bb111 mmc: sdhci: Rework SDHCI_QUIRK_BROKEN_R1B
As noted in commit 3a6383207b ("mmc: sdhci: add the quirk for broken
r1b response"), some MMC controllers don't always set the transfer
complete bit with R1b responses.

According to the SD Host Controller Simplified Specification v4.20,

> In the case of a command pairing with response-with-busy[, Transfer
> Complete] is set when busy is de-asserted. Refer to DAT Line Active
> and Command Inhibit (DAT) in the Present State register.

By polling the DAT Line Active bit in the present state register, we can
detect when we are no longer busy, without waiting for a long timeout.
This results in much faster reads/writes on buggy controllers.

5ed1c55fb4 misc: i2c_eeprom: consider pagesize when writing to eeprom
Calculate the maximum length of the buffer when writing
across the page boundary. If the buffer length (len)
exceeds the page boundary (pagesize), split it. Use this
length instead of comparing the length with the pagesize,
because if the write start address (offset) is not at the
beginning of a page and the page_offset + len is greater
than the page boundary (pagesize), the write operation
would overflow the current page and the behaviour can be
undefined (e.g. at24).

33e8020fd1 board: siemens: iot2050: Fix M.2 detection
The "simpler" the logic, the higher the probability to not test and get
things wrong, again: The absence of a "-PG2" suffix is not sufficient to
derive that we are on PG1. There is also "IOT2050-ADVANCED-M2".

Finally fix that by exactly matching against the two PG1 device names.

While changing this, we can also drop the not really needed check for
!board_is_sr1 in board_is_m2 and call the boards by their names
("board_is_pg1").

Enable USB device and fastboot support which may be used to load the
Toradex Easy Installer FIT image.

While at it also enable USB mass storage aka UMS support.

Note that the i.MX 8M Plus recovery mode support is based on the USB
boot stage of the BOOTROM and does NOT require USB SDP SPL aka serial
downloader support.

bootX measurements and measurement API moved to u-boot core:

Up to now, U-Boot could perform measurements and EventLog creation as
described by the TCG spec when booting via EFI.

The EFI code was residing in lib/efi_loader/efi_tcg2.c and contained
both EFI specific code + the API needed to access the TPM, extend PCRs
and create an EventLog. The non-EFI part proved modular enough and
moving it around to the TPM subsystem was straightforward.

With that in place we can have a common API for measuring binaries
regardless of the boot command, EFI or boot(m|i|z), and contructing an
EventLog.

I've tested all of the EFI cases -- booting with an empty EventLog and
booting with a previous stage loader providing one and found no
regressions.  Eddie tested the bootX part.

Eddie also fixed the sandbox TPM which couldn't be used for the EFI code
and it now supports all the required capabilities. This had a slight
sideeffect in our testing since the EFI subsystem initializes the TPM
early and 'tpm2 init' failed during some python tests. That code only
opens the device though, so we can replace it with 'tpm2 autostart'
which doesn't error out and still allows you to perfom the rest of the
tests but doesn't report an error if the device is already opened.

There's a few minor issues with this PR as well but since testing and
verifying the changes takes a considerable amount of time, I prefer
merging it now.

Heinrich has already sent a PR for -master containing "efi_loader: fix
EFI_ENTRY point on get_active_pcr_banks" and I am not sure if that will
cause any conflicts, but in any case they should be trivial to resolve.

Both the EFI and non-EFI code have a Kconfig for measuring the loaded
Device Tree.  The reason this is optional is that we can't reason
when/if devices add random info like kaslr-seed, mac addresses etc in
the DT. In that case measurements are random, board specific and
eventually useless.  The reason it was difficult to fix it prior to this
patchset is because the EFI subsystem and thus measurements was brought
up late and DT fixups might have already been applied. With this
patchset we can measure the DT really early in the future.

Heinrich also pointed out that the two Kconfigs for the DTB measurements
can be squashed in a single one and that the documentation only explains
the non-EFI case.  I agree on both but as I said this is a sane working
version, so let's pull this first it's aleady big enough and painful to
test.
