[U-Boot] [PATCH 0/3] Clean up up malloc pool init

[U-Boot] [PATCH 0/3] Clean up up malloc pool init

[Peter Tyser]

Most architectures share nearly identical malloc initialization code.
This series factors out the common code into dlmalloc.c.

I tested on the XPedite5200, an mpc8548-based board.  Let me know if anyone
runs into any issues on other architectures.

Peter Tyser (3):
  Consolidate arch-specific sbrk() implementations
  Standardize mem_malloc_init() implementation
  Consolidate arch-specific mem_malloc_init() implementations

[U-Boot] [PATCH 2/3] Standardize mem_malloc_init() implementation

[Peter Tyser]

This lays the groundwork to allow architectures to share a common
mem_malloc_init().

Note that the x86 implementation was not modified as it did not fit the
mold of all other architectures.

That would mean you have to touch N board configurations. To me it
sounds as if this was not per-board choice, but an architecture-
specific decision. And a CONFIG_* name seems wrong (it should be
CONFIG_SYS_* at least).

> and then define it in the configs/arch.h

What is configs/arch.h?  There is no such file, and the name does not
make sense to me.

Best regards,

Wolfgang Denk

Yiour terminology is confusing. I guess what you write is not what you
mean. The closes thing to "arch config file" would be cpu/*/config.mk;
but I don;t think you mean that?

Ah. well, configs/arch.h != asm/config.h !!

I thought the cleanest fix would be to update the x86 call to 
mem_malloc_init() to match all the other architectures', but didn't want 
to delve into the x86 arch init code.

I think adding a new CONFIG_* option to handle 1 non-conforming 
architecture is dirtier than syncing up the x86 init code in any case.

Best,
Peter

I am currently undertaking a fairly significant tidy up of some x86
loose ends. One that I noticed (and have not touched just yet) is how
the x86 allocates the malloc pool. After these (Peter's) patches get
applied, I will revisit the x86 malloc and bring it into line with the
other arches

Q:  How do you tell if you're making  love  to  a  nurse,  a  school-
    teacher, or an airline stewardess?
A:  A nurse says: "This won't hurt  a  bit."  A  schoolteacher  says:
    "We're  going to have to do this over and over again until we get
    it right." An airline stewardess says: "Just hold this over  your
    mouth and nose, and breath normally."
