[PATCH v2 00/13] bootm: prepare loadable abstraction rework

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

v1 -> v2:
  - Dropped "efi: payload: bootm: fix memory corruption on initrd load error":
    Sent out separately
  - Dropped "bootm: cache os_file for appendroot purposes"
    Preparatory patch that has been superseded for the second part of
    this rework
  - Move memory_bank_lookup_region() closer to the bootm_load()
    functions, and make sure same argument are used for both.
  - Switch over efi_loader_bootm as well by using bootm_load_os
  - In fit_open, propagate error for short reads correctly
  - add kernel-doc for open_fdt, resize_region,
    file_read_and_detect_boot_image_type
  - export file_read_and_detect_boot_image_type for future use
  - fix intermittent regression for initrd loading
  - resize_region: return error on resizing to 0 size (Sascha)
  - resize_region: check that there is no conflict with child resources
    (Sascha)

Despite previous work to move out uImage and FIT-specific parts out of
the bootm code, common/boot.c still has a number of places where code
checks if it's a FIT image, a uImage or a plain file.

This series lays the groundwork for a second series that will:
- Introduce the concept of a loadable for deferred boot component loading
- Switch all code to generate loadables once at the start and then
  extracting them later on, irrespective of their origin
- Implement a more robust and powerful override mechanim, where
  individual loadables can be switched against each other

Before we can do that, we however need to refactor the code a bit and
add some helpers that are going to be used.

Ahmad Fatoum (13):
  FIT: implement fit_count_images
  FIT: add image index argument to fit_open_image
  resource: implement gap-aware lookup_region
  bootm: give bootm_load_ functions an end address
  bootm: store separate image_type and kernel_type
  bootm: fit: move length calculation into fit_open
  libfile: factor out zero-page resistant read_file as
    __read_full_anywhere
  resource: implement resize_region
  bootm: rename image_data::os/initrd with _uimage suffix
  uimage: record original file name in uimage_handle
  bootm: factor out file detection into helper
  efi: payload: bootm: add dry run support
  efi: initrd: make efi_initrd_register initrd pointer param const
