078702fc47 [flash] Teach mx25l SPI flash driver to interact with fdt_slicer and geom_flashmap
This teaches the mx25l driver (sys/dev/flash/mx25l.c) to interact with
sys/dev/fdt/fdt_slicer.c and sys/geom/geom_flashmap.c.

This allows systems with SPI flash to benefit from the possibility to define
flash 'slices' via FDT, just the same way that it's currently possible for
CFI and NAND flashes.

Tested:

* Carambola 2, AR9331 + SPI NOR flash

acae2332ed Fix panic on table/table entry delete. The panic could have happened
if more than 64 distinct values had been used.

Table value code uses internal objhash API which requires unique key
  for each object. For value code, pointer to the actual value data
  is used. The actual problem arises from the fact that 'actual' e.g.
  runtime data is stored in array and that array is auto-growing. There is
  special hook (update_tvalue() function) which is used to update the pointers
  after the change. For some reason, object 'key' was not updated.
  Fix this by adding update code to the update_tvalue().

d6a31ebe03 Prevent loader.conf load failure due to unknown console entries
When processing loader.conf if console contained an entry for an unsupported
console then cons_set would return an error refusing to set any console.

This has two side effects:

1. Forth would throw a syntax error and stop processing loader.conf at that
  point.
2. The value of console is ignored.

#1 Means other important loader.conf entries may not be processed, which is
   clearly undesirable.
#2 Means the users preference for console aren't applied even if they did
   contain valid options. Now we have support for multi boot paths from a
   single image e.g. bios and efi mode the console preference needs to deal
   with the need to set preference for more than one source.

Fix this by:
* Returning CMD_OK where possible from cons_set.
* Allowing set with at least one valid console to proceed.

fb833979a5 Fix EFI UFS caching
EFI was mixing caching in two separate places causing issues when multiple

Eliminate this by removing fsstat and re-factoring fsread into fsread_size,

Also:
* Enhance some error print outs.
* Fix compilation under UFS1_ONLY and UFS2_ONLY
* Use sizeof on vars instead of structs.
* Add basic parameter validation to fsread_size.

Previously the code would just increment statistics while only holding a
