This does not seem right, since if the log level is high enough then
there should be some sort of message. So in that case, this series

This mimics the behaviour for the log_...() macros like log_debug() and

To quote the series author, Patrick Delaunay:
On STM32MP15x platform we can use OP-TEE, loaded in DDR in a region
protected by a firewall. This region is reserved in the device with
the "no-map" property as defined in the binding file
doc/device-tree-bindings/reserved-memory/reserved-memory.txt.
Sometime the platform boot failed in U-Boot on a Cortex A7 access to
this region (depending of the binary and the issue can change with compiler
version or with code alignment), then the firewall raise an error,
for example:
After investigation, the forbidden access is a speculative request performed
by the Cortex A7 because all the DDR is mapped as MEMORY with CACHEABLE
property.
The issue is solved only when the region reserved by OP-TEE is no more
mapped in U-Boot as it is already done in Linux kernel.
Tested on DK2 board with OP-TEE 3.12 / TF-A 2.4:
With hard-coded address for OP-TEE reserved memory,
the error doesn't occur.
void dram_bank_mmu_setup(int bank)
{
....
for (i = start >> MMU_SECTION_SHIFT;
i < (start >> MMU_SECTION_SHIFT) + (size >> MMU_SECTION_SHIFT);
i++) {
option = DCACHE_DEFAULT_OPTION;
if (i >= 0xde0)
option = INVALID_ENTRY;
set_section_dcache(i, option);
}
}
Just by modifying the test on 0xde0 to 0xdf0, the OP-TEE memory protected
by firewall is mapped cacheable and the error occurs.
I think that it can be a general issue for ARM architecture: the "no-map" tag
of reserved memory in device should be respected by U-Boot if firewall
is configured before U-Boot execution.
But I don't propose a generic solution in
arm/lib/cache-cp15.c:dram_bank_mmu_setup()
because the device tree parsing done in lmb_init_and_reserve() takes a
long time when it is executed without data cache.
stm32mp: don't map the reserved region with no-map property
No more map the reserved region with "no-map" property by marking
the corresponding TLB entries with invalid entry (=0) to avoid
speculative access.
The device tree parsing done in lmb_init_and_reserve() takes a
long time when it is executed without data cache, so it is called in
enable_caches() before to disable it.
This patch fixes an issue where predictive read access on secure DDR
OP-TEE reserved area are caught by firewall.
image-fdt: save no-map parameter of reserve-memory
Save the 'no-map' information present in 'reserved-memory' node to allow

Additional properties:
...
no-map (optional) - empty property
- Indicates the operating system must not create a virtual mapping

nor permit speculative access to it under any circumstances other
than under the control of the device driver using the region.

These drivers are sunxi platform-specific, and so are of interest to the
sunxi maintainers.
In fact, as there is no PHY driver maintainer, drivers/phy/allwinner had
no maintainer at all.

sunxi: Bring back SD card as MMC device 0
Commit 2243d19e5618 ("mmc: mmc-uclass: Use dev_seq() to read aliases
node's index") now actually enforces U-Boot's device enumeration policy,
where explicitly named devices come first, then any other non-named
devices follow, without filling gaps.
For quite a while we have had an "mmc1 = &mmc2;" alias in our
sunxi-u-boot.dtsi, which now leads to the problem that the SD card
(which was always mmc device 0) now gets to be number 2.
This breaks quite some boot scripts, including our own distro boot
commands, and some other features looking at $mmc_bootdev, also
fastboot.
Just add an explicit mmc0 alias in the very same file to fix this and
restore the old behaviour.

Replace CONFIG_HASH_CALCULATE by CONFIG_HASH

efi_loader: Work-around build issue due to missing hash_calculate()
The hash_calculate() symbol is provided by hash-checksum.c. It depends
on hash_progressive_lookup_algo(), provided when CONFIG_HASH=y.
The issue is that hash_calculate() is used by the efi_loader,
irregardless of CONFIG_FIT_SIGNATURE. As pointed out in
commit 87316da05f2f ("lib: introduce HASH_CALCULATE option"),
enabling hash_calculate() based on CONFIG_FIT_SIGNATURE is incorrect.
To resolve this, use CONFIG_HASH as the compile switch for
hash-checksum.c. This ensures that all dependencies are compiled, and
is the most natural Kconfig to use.
There is the issue of having to 'select HASH' in a couple of places
that already 'select SHA256'. This is a deeper problem with how hashes
are organized, and fixing it is beyonf the scope of this change.

When we think of Kconfig, we usually think of features that we like
to enable or not. Ideally, we wouldn't use Kconfig to fix a build
issue, although sometimes it might make sense. With Kconfig it's hard
to guarantee that the fix is universal. We can only say that it works
for the set of tested configurations. In the majority of cases, it's
preferable to let the linker figure things out for us.
The reverted commit attempted to fix a build issue by adding an
invisible Kconfig option. This is wrong in several ways:
It invents a new Kconfig variable when CONFIG_HASH already
exists for the same purpose.
Second, hash-checksum.c makes use of the hash_progressive_lookup_algo()
symbol, which is only provided with CONFIG_HASH, but this dependency
was not expressed in the reverted patch.
It feels like Kconfig is turning into a listing of all available
source files, and a buffet to 'select' which ones to compile. The
purpose of this revert is to enable the next change to make use of
CONFIG_HASH instead of adding to Kconfig.

efi_loader: Fix coverity warnings for efi tcg2 protocol
Coverity reported 3 warnings on the current code.
CID 331856, 331855, 331854 on the latest scan.
Fix the rest of the warnings by initializing the variables before
passing them to tpm2_get_pcr_info().
In order to avoid future warnings and errors initialize them to 0 within
the function as well, since the values are always OR'ed after querying the
hardware.
