[RFC PATCH v2 0/1] Current strategy is to use right/left shift to implement div/mult

[Mauro Condarelli]

this work *only* under the assumption block-size is always a power
of 2; I was unable to find where it is enforced.

Alternative strategy would be to use directly the lower-level do_div(),
or the lldiv() wrapper instead.

Please review because I did not find a place where it is enforced
that struct blk_desc blksz is a a power of 2 and thus using log2blksz
is actually correct.

Changes in v2:
- replace division with right shift (Daniel Schwierzeck).
- remove vocore2-specific change (Daniel Schwierzeck).
- add warning to Kconfig about CONFIG_SYS_MALLOC_LEN (Tom Rini).

Mauro Condarelli (1):
  Fix missing __udivdi3 in SquashFS implementation.
