* Consolidate arch-specific mem_malloc_init() implementationsPeter Tyser2009-09-041-12/+2

* Standardize mem_malloc_init() implementationPeter Tyser2009-09-041-8/+7
| | | | | | | | | | 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. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>

* stdio/device: rework function naming conventionJean-Christophe PLAGNIOL-VILLARD2009-07-181-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far the console API uses the following naming convention: ======Extract====== typedef struct device_t; int device_register (device_t * dev); int devices_init (void); int device_deregister(char *devname); struct list_head* device_get_list(void); device_t* device_get_by_name(char* name); device_t* device_clone(device_t *dev); ======= which is too generic and confusing. Instead of using device_XX and device_t we change this into stdio_XX and stdio_dev This will also allow to add later a generic device mechanism in order to have support for multiple devices and driver instances.

* lib_arch/board.c: Move malloc initialization before flash_init()Stefan Roese2009-06-121-2/+4
| | | | | | | | | | | | | | | | | | | This patch moves the malloc initialization before calling flash_init(). Upcoming changes to the NOR FLASH common CFI driver with optional MTD infrastructure and MTD concatenation support will call malloc(). And nothing really speaks against enabling malloc just a little earlier in the boot stage. Some architectures already enable malloc before calling flash_init() so they don't need any changes here.

* lib_*/board.c: do not initialize bi_enet*addr in global dataMike Frysinger2009-03-201-5/+0
| | | | | | | | | | | | | | | | | | | | | | | Since everyone is using the environment for mac address storage, there is no point in seeding the global data.

* allow ports to override go behaviorMike Frysinger2008-04-181-0/+10
| | | | | | Split the arch-specific logic out of the common go code and into a dedicated weak function called do_go_exec() that lives in cpu directories. This will need review from i386/nios people to make sure I didn't break them.
