Hello,

This is the second chunk of patches, there are still two open (bootstrap and IO_MANAGER) since last chunk. Since the first patches does not depend on anything in chunk B I descided to move on.

As before, PATCH means I will send them on the rtems-devel list solely, PR means I will file a bugzilla PR.

Note that GRETH-autoneg patch closes already opened PR 1465, thanks to Joris the PR was brought up again.

Thanks,
Daniel

     GRETH: added support for non-snooping GRETH 10/100 systems

     When data cache snooping is not present the cache needs
     flushing, the SPARC LEON CPUs does not have to ability
     to flush individual cache rows and flushing all cache is
     expensive. Instead the LDA instruction is used to force
     cache miss on individual loads during the IP-align copy
     operation required anyway.

     GRETH GBIT non-snooping systems are still unsupported,
     since it use zero-copy (can deal with unaligned DMA).

     Also, made the GRETH driver only built on LEON2/LEON3
     platforms.

     SMC91111: ERC32 was never supported by driver

     Moved the intelligence whether the driver is supported or not
     completely to the BSP, now that bsp.h is included (even though it
     is a driver... hmm). The ERC32 was never supported, so HAS_SMC91111
     is not added to erc32/include/bsp.h.

     LEON3: make SHM driver configurable using weak

     Since the configuration struct is always present one can let
     DATA initialize it to reduce footprint, at the same time it
     is made weak to let the user able to configure the SHM driver
     without editing the driver code.

     SPARC BSPs: bsp_early_malloc() routine for startup memory allocation

     If bsp_early_malloc() is called early during boot room will be
     allocated after BSS END. If the function is called after boot
     is will call malloc() instead. The returned memory is not freeable
     and always 8-byte aligned.

     If the bsp_early_malloc() isn't called the function is not
     dragged in and the workspace will be unmodified in size.

     SPARC: added libcpu lowlevel access and byteorder routines/definitions

     The low level routines can be used in different occasions, it will be
     required when accessing PCI.
