[PATCH v8 0/9] Add support for loading main_r5fss0_core0

[Keerthy]

This patch series enables mcu_r5fss0_core0 & main_r5fss0_core0.
Tested for firmware loading and execution on J721e.

Changes in v8:

  * Dropped patch to set_env_default in the env/nowhere driver.
    That was causing memory over run issues on sandbox defconfig
    with simple_alloc.

    Instead used env_relocate in place of env_load which does
    default environment set up to do env_set calls.

  * Fixed IMX build warning.

All the travis tests passed:

https://travis-ci.org/Keerthyj/u-boot/builds/649274826

Changes in v7:

  * Added BSD-2 SPDX on lib/elf.c file.
  * Added Tom's Reviewed-by for the relevant patches.

Changes in v6:

  * Fixed the imx build issue.

Changes in v5:

  * Moved the fs_loader node under r5-common-proc-board-u-boot.dtsi
  * Added more information on the envnowhere patch.
  * Added help LIB_ELF option and removed user configurable description.

Changes in v4:

  * Changed env variable names, config names and enhanced commit logs.

Changes in v3:

  * Removed saving env in MMC and fixed env saving in SPL when nowhere
    option is set.

Changes in v2:

  * Factored out all the generic elf handling functions under lib/elf.c
