On the list.
Patch updated to Joel and Gedares comments. Gadare: Looks good to me.

> LIST 5a2482c SPARC BSPs: bsp_early_malloc() routine for startup memory allocation
On the list.
Discussion about making bsp_early_malloc() available on all BSPs, it was concluded that it is not really needed for all BSPs. Unsure of the status here.

BUG 2015
Fixed Gedares comments about global variable initialization: version 2 submitted to list and bugzilla

On list.
Gedare: Looks good.

BUG 1465.
Joris: This looks fine
Gedare: looks good
