Currently there is some limitation with mounting an
EXT4 partition to retrieve a file for booting when
the partition was not properly umounted during the
previous usage (ex. powering off an OS without
using 'poweroff' command, unplugging power, etc.).
There is no recovery support in the Ext23Lib but
as a temporary solution we can ignore the recovery
bit to avoid boot issues when the recovery bit is
flipped due to unexpected power loss.

When determining which extent node to fetch
the filesystem block address from for a file's

Current SBL does not call board ReadyToBoot & EndOfFirmware phases

This patch will add support for updating multiple firmwares
using a single capsule image.
Following modifications are made for existing firmware update flow
1) Gather and validate capsule image
2) State Machine will be set to capsule processing state.
3) Signature of the capsule image is now stored in reserved region
During each reboot until the end of firmware update, stored signature
will be compared against the capsule image signature to make sure
capsule image is not modified until the end of firmware update.
4) Process Capsule image to gather firmware images
5) Each Firmware image information will be stored in reserved region
using FW_UPDATE_COMP_STATUS. Update pending will be marked to
update pending state indicating that this image is not processed.
6) Firmware update will use the reserved region comp structures starting
with the first image with update pending state, update the comp update
pending field to processing and applies the image. After the update, pending
field will be updated to Done and updates the status of the update in the
component structure and moves on to next image found.
7) After all the component structure in the reserved region updating pending
field are set to Done. Firmware update mode is exited.
