[PATCH v4 00/19] vbe: Series part E

[PATCH v4 00/19] vbe: Series part E

[Simon Glass]

This includes various patches towards implementing the VBE abrec
bootmeth in U-Boot. It mostly focuses on SPL tweaks and adjusting what
fatures are available in VPL.

Changes in v4:
- Add an option to avoid code bloat with rcar3_salvator-x for example

Changes in v3:
- Add new patch to avoid size growth in spl_mmc_find_device() debug
- Use strlcpy() instead of strncpy()
- Rebase to master

Changes in v2:
- Add field names into the message
- Fix 'depends on SPL' to depend on TPL
- Depend on TPL/VPL as well
- Drop patch 'serial: ns16550: Allow clocks to be missing'

Simon Glass (19):
  spl: mmc: Avoid size growth in spl_mmc_find_device() debug
  image: Add a prototype for fit_image_get_phase()
  boot: Allow FIT to fall back from best-match option
  bootstd: Avoid sprintf() in SPL when creating bootdevs
  boot: Respect the load_op in fit_image_load()
  malloc: Show amount of used space when memory runs out
  malloc: Provide a simple malloc for VPL
  Support setting a maximum size for the VPL image
  spl: Report a loader failure
  spl: Allow serial to be disabled in any XPL phase
  spl: Support a relocated stack in any XPL phase
  spl: Drop use of uintptr_t
  spl: Drop a duplicate variable in boot_from_devices()
  spl: Add some more debugging to load_simple_fit()
  spl: lib: Allow for decompression in any SPL build
  boot: Allow use of FIT in TPL and VPL
  lib: Allow crc8 in TPL and VPL
  boot: Imply CRC8 with VBE
  hash: Plumb crc8 into the hash functions

[PATCH v4 01/19] spl: mmc: Avoid size growth in spl_mmc_find_device() debug

[Simon Glass]

The for() loop ends up being in the code even if the log_debug() does
nothing. Add a condition to fix this.
