31a7688cbe tools: mkeficapsule: use pkg-config to get -luuid and -lgnutls
Instead of hardcoding -luuid -lgnutls as the flags needed to build
mkeficapsule, use pkg-config when available.

We gracefully fallback on the previous behavior of hardcoding -luuid
-lgnutls if pkg-config is not available or fails with an error.

b661c1bc92 arm: mach-k3: security: Remove certificate if detected on GP device
If the device is a GP and we detect a signing certificate then remove it.
It would fail to authenticate otherwise as the device is GP and has no
secure authentication services in SYSFW.

This shouldn't happen often as trying to boot signed images on GP devices
doesn't make much sense, but if we run into a signed image we should at
least try to ignore the certificate and boot the image anyway. This could
help with users of GP devices who only have HS images available.

If this does happen, print a nice big warning.

a0379c6fe3 arm: mach-k3: security: Bypass image signing at runtime for GP devices
We can skip the image authentication check at runtime if the device is GP.
This reduces the delta between GP and HS U-Boot builds. End goal is
to re-unify the two build types into one build that can run on all
device types.

e1ef04fb3e arm: mach-k3: security: Allow signing bypass if type is HS-FS
On HS-FS devices signing boot images is optional. To ease use
we check if we are HS-FS and if no certificate is attached
to the image we skip the authentication step with a warning
that this will fail when the device is set to security enforcing.

K3 SoCs are available in a number of device types such as
GP, HS-FS, EMU, etc. Like OMAP SoCs we can detect this at runtime
and should print this out as part of the SoC information line.

bf28d9a659 spl: mmc: Use correct MMC device when loading image
When attempting to load images from multiple MMC devices in sequence,
spl_mmc_load() chooses the wrong device from the second attempt onwards.

The reason is that MMC initialization is only done on its first call and
spl_mmc_load() will then continue using this same device for all future
calls.

Fix this by checking the devnum of the "cached" device struct against
the one which is requested.  If they match, use the cached one but if
they do not match, initialize the new device.

This fixes specifying multiple MMC devices in the SPL's boot order to
fall back when U-Boot Proper is corrupted or missing on the first
attempted MMC device.

c588ca8734 drivers: xen: events: fix build issues with disabled Xen HVC
Some setups do not use Xen hypervisor console for logging, e.g. they
use emulated PL011 hardware or shared peripherals (real UART). In such
cases Xen HVC will be disabled on a build time and will cause issues in
current driver implementation.

This commit fixes build issues in Xen event channel driver, caused
by absense of console event channel, that is not available when console
config is disabled. Now console related code will be removed when
Xen HVC is turned off.

786d9f1a82 powerpc: mpc85xx: Add support for generating QorIQ pre-PBL eSDHC boot sector
QorIQ U-Boot binary for SD card booting compiled during build process
(either u-boot.bin or u-boot-with-spl.bin) cannot be directly loaded by
QorIQ pre-PBL BootROM. Compiled U-Boot binary first needs to be processed
by Freescale boot_format tool as described in doc/README.mpc85xx-sd-spi-boot

BootROM requires that image on SD card must contain special boot sector.
Implement support for generating this special boot sector directly in
U-Boot start code. Boot sector needs to be at the beginning of the image,
so when compiling only proper U-Boot without SPL then it needs to be in
proper U-Boot. When compiling SPL with proper U-Boot then it needs to be
only in SPL.

Support can be enabled by a new config option FSL_PREPBL_ESDHC_BOOT_SECTOR.
Via other two additional options FSL_PREPBL_ESDHC_BOOT_SECTOR_START and
FSL_PREPBL_ESDHC_BOOT_SECTOR_DATA it is possible to tune how final U-Boot
image could be stored on the SD card.

pinctrl driver and set .request and .rfree callbacks in GPIO driver to
pinctrl_gpio_request / pinctrl_gpio_free functions.
