048c6e8956 spl: lz4: Allow use of lz4 compression in SPL
In some cases U-Boot is compressed and it is useful to be able to
decompress it in SPL. Add a Kconfig and Makefile change to allow this.
Note that this does not actually implement decompression.

410d9b6446 fdt: Fix uncompress_blob() for U-Boot proper
When U-Boot proper is compiled with CONFIG_MULTI_DTB_FIT and tries
to call uncompress_blob(), it fails with -ENOTSUPP. This is because
the full implementation of this function which includes compression
is available only in SPL. In U-Boot proper or if the compression is
not enabled, the blob is not compressed and thus can be passed to
locate_dtb_in_fit() in fdtdec_setup() without any changes. Pass the
blob without any changes if compression is not enabled instead of
failing.

21ebf2adde fdt_region: Ensure that depth never goes below -1
A specially crafted FIT image makes it possible to overflow the stack
with controlled values when using the verified boot feature. Depending
on the memory layout, this could be used to overwrite configuration
variables on the heap and setting them to 0, e.g. disable signature
verification, thus bypassing it.

This change fixes a bug in fdt_find_regions where the fdt structure is
parsed. A lower value than -1 of depth can lead to a buffer underflow
write on the stack.

ef329a6a73 sysreset: Remove DM_FLAG_PRE_RELOC flag in various drivers
When a driver declares DM_FLAG_PRE_RELOC flag, it wishes to be
bound before relocation. However due to a bug in the DM core,
the flag only takes effect when devices are statically declared
via U_BOOT_DEVICE(). This bug has been fixed recently by commit
"dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in
lists_bind_fdt()", but with the fix, it has a side effect that
all existing drivers that declared DM_FLAG_PRE_RELOC flag will
be bound before relocation now. This may expose potential boot
failure on some boards due to insufficient memory during the
pre-relocation stage.

To mitigate this potential impact, the following changes are
implemented:

- Remove DM_FLAG_PRE_RELOC flag in the driver, if the driver
  only supports configuration from device tree (OF_CONTROL)
- Keep DM_FLAG_PRE_RELOC flag in the driver only if the device
  is statically declared via U_BOOT_DEVICE()
- Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for
  drivers that support both statically declared devices and
  configuration from device tree

f26ce03b44 efi_driver: blk: Switch to use platdata_auto_alloc_size for the driver data
Currently the efi block driver uses priv_auto_alloc_size for the
driver data, however that's only available after the device probe
phase. In order to make it accessible in an earlier phase, switch
to use platdata_auto_alloc_size instead.

This patch is the prerequisite for the follow up patch of DM BLK
driver changes to work with EFI loader.

c7b3a7ee53 optee: adjust dependencies and default values for dram
We may have, the not yet considered, scenario where OPTEE is loaded before
u-boot and *not* by u-boot, e.g, the boot flow using the ARM Trusted
Firmware (ATF), where in the 32bit flow is:
BootRom->ATF(BL2)->Optee(BL32)->u-boot(BL33)

In this case we need still to reserve the memory used by optee, to avoid
for example to realocate ourself to the same address at the end of DRAM.
So, we change here the dependencies on the OPTEE lib and we set the default
size and base of TZRAM to zero.

Rather than change how we unwind the function it makes the most sense to

EFI_FILE_MODE_CREATE is set in open_mode.

The SCT tries to read a directory with EFI_FILE_DIRECTORY.

As EDK2 allows this we should not be more strict.
