Hi Bryan,

> v3:
> - Reword commit message of patch #16 - Breno
>
> - This patchset now relies on five in-flight patch-sets the first four of
>   which should be applied first
>
> 1. [PATCH v3 0/3] NXP WaARP7 set serial# from OTP fuses for USB iSerial
>    Already has a Reviewed-by from Fabio
>
> 2. [PATCH v3 0/2] imx: hab: Add helper functions for scripted HAB auth
>    Has a Reviewed-by: from Breno
>
> 3. [PATCH v3 0/2] WaRP7 unify secure and non-secure defconfigs
>
> 4. Pierre-Jean's generic load patches
>
>    [U-Boot] [PATCH v3 1/2] warp7: include/configs: use generic fs commands
>    in CONFIG_EXTRA_ENV_SETTINGS
>
>    [U-Boot] [PATCH v3 2/2] warp7: configs: enable CONFIG_CMD_FS_GENERIC
>
> 5. [PATCH] bootm: Align cache flush begin address
>    This last patch can be applied in any order
>
> v2:
> - Ensure warp7_defconfig boots existing yocto with this change plus the
>   automated HAB layer being added here following on from "[PATCH v3 0/2]
>   WaRP7 unify secure and non-secure defconfigs"
>
> - Fix reference to partition #1 versus partition #2 in select uuidpart
>   patch
>
> - Rebase on top of Pierre-Jean Texier generic load patches
>
> - Drop my patch which did the same thing as Pierre-Jean's patch via
>   ${loadcmd}
>
> - Update example boot.scr from v1 to reflect use of generic 'load' command
>
> - This patchset now relies on four in-flight patch-sets which all have the
>   relevant Reviewed-by tags from the board Maintainer Fabio.
