meta-intel: Reorganize the layout to remove common

Remove the concept of the common directory and move all the recipes-* dirs
to the top level as a normal layer would be. layer.conf is updated appropriately

+Subject: [PATCH] sd-boot: stub: check LoadOptions contains data
+
+With some UEFI shells LoadOptionsSize is reported being > 0
+but the corresponding LoadOptions does not contain any data
+(the first element has value 0).
+
+When that happens, the stub feature that allows .cmdline to be
+replaced by what's in LoadOptions ends up copying nothing/random
+data to the kernel cmdline resulting in different kinds of boot
+problems.
+
+To fix this, add a check to see if LoadOptions contains data
+before replacing the .cmdline.
+
+Upstream-Status: Accepted [https://github.com/systemd/systemd/pull/5467]
+
+Fixes [YOCTO #11078].

+Subject: [PATCH 2/3] sd-boot: Load board-specific boot entries from RMC
+ database
+
+RMC provides a centralized database file on ESP. The DB contains
+fingerprints and any file blobs associated to physical boards.
+Callers can fetch board-specific data with fingerprint info
+collected from board at runtime if there is any record matched
+board's fingerprint.
+
+To let bootloader know which file blob in RMC should be queried,
+a special config file BOOTENTRY.CONFIG is defined as:
+
+boot.conf
+install.conf
+
+Bootloader calls RMC APIs and other functions to perform these
+tasks before it shows boot menu to user:
+
+(1) Load RMC database file from ESP
+(2) Collect fingerprint data from board
+(3) Query BOOTENTRY.CONFIG from RMC DB with fingerprint
+(4) Parse BOOTENTRY.CONFIG to know names of boot entry files
+(5) Query boot entry files one by one from RMC DB, and add
+    them into sd-boot config data.
+
+The final effect is that bootloader will show board-specific
+boot entries in boot menu to user. User then can choose one
+of them to boot system with the selected configuration.
+
+If any of these steps fails, bootloader simply skips loading
+RMC configs or any entry file not successfully fetched from
+RMC DB. Once any entry is loaded successfully from RMC DB,
+bootloader skips loading any boot entries from ESP.

+Subject: [PATCH] sd-boot: support global kernel command line in EFI stub
+
+This change integrates rmc into EFI stub and supports a
+global fragment (RMC KBOOTPARAM) that is appended to the
+cmdline at boot.
+
+The fragment is board-specific and read from the database.
+
+Implements [YOCTO #10924].
