2009-12-15mpc85xx, mpc86xx: Fix gd->cpu pointer after relocationPeter Tyser
The gd->cpu pointer is set to an address located in flash when the probecpu() function is called while U-Boot is executing from flash. This pointer needs to be updated to point to an address in RAM after relocation has occurred otherwise Linux may not be able to boot due to "fdt board" crashing if flash has been erased or changed. This bug was introduced in commit a0e2066f392782730f0398095e583c87812d97f2.

2009-10-16mpc85xx: Fix booting on various boardsAnton Vorontsov
commit 0e870980a64584a591af775bb9c9fe9450124df9 ("8xxx: Removed CONFIG_NUM_CPUS from 85xx/86xx") breaks U-Boot on various boards, namely the ones that call get_sys_info() from board_early_init_f(). get_sys_info() calls cpu_numcores(), which depends on probecpu() being called before. But probecpu() is called after board_early_init_f(), and so cpu_numcores() returns random values, which in turn crashes get_sys_info(). To fix the issue we place probecpu() before board_early_init_f() in an initialization sequence. Booting on the following boards should be revived now: mpc8540ads mpc8541cds mpc8548cds mpc8555cds mpc8560ads mpc8568mds mpc8569mds and maybe more.

The number of CPUs are getting detected dynamically by checking the processor SVR value. Also removed CONFIG_NUM_CPUS references from all the platforms with 85xx/86xx processors. This can help to use the same u-boot image across the platforms. Also revamped and corrected few Freescale Copyright messages.

2009-07-23ppc: Unlock cache-as-ram in a consistent mannerPeter Tyser
Previously, non-e500 architectures only unlocked their data cache which was used as early RAM when booting to Linux using the "bootm" command. This change causes all PPC boards with CONFIG_SYS_INIT_RAM_LOCK defined to unlock their data cache during U-Boot's initialization. This improves U-Boot performance and provides a common cache state when booting to different OSes. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
2009-07-18stdio/device: rework function naming conventionJean-Christophe PLAGNIOL-VILLARD
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.

2009-06-12lib_arch/board.c: Move malloc initialization before flash_init()Stefan Roese
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.

2009-03-20ppc: mark global bi_enet*addr as legacyMike Frysinger
The environment is the canonical storage location of the mac address, so we're killing off the global data location and moving everything to querying the env directly. In the ppc case, these things are part of the legacy ABI, so keep them around but mark them as legacy so no new code will touch them. Also stop calling load_sernum_ethaddr() since all boards now implement this as a stub. Signed-off-by: Mike Frysinger <vapier@gentoo.org> CC: Ben Warren <biggerbadderben@gmail.com>
2009-03-20boards: get mac address from env and move load_sernum_ethaddr() to board initMike Frysinger
The environment is the canonical storage location of the mac address, so we're killing off the global data location and moving everything to querying the env directly. Rather than have common ppc code call a board-specific function like load_sernum_ethaddr(), have each board call it in its own board-specific misc_init_r() function.

2009-01-27SATA: do not auto-initialize during bootMike Frysinger
Rather than have the board code initialize SATA automatically during boot, make the user manually run "sata init". This brings the SATA subsystem in line with common U-Boot policy. Rather than having a dedicated weak function "is_sata_supported", people can override sata_initialize() to do their weird board stuff. Then they can call the actual __sata_initialize().

2008-11-10lib_ppc: Move trap_init to occur earlierBecky Bruce
Doing trap_init immediately once we're running from RAM means we're no longer dependent on the physical location of the flash on non-BookE platforms. Before trap_init, those platforms switch to real mode and go to 0xfff00100 on exception. After the switch, they go to 0x00000100 This makes it easier to move the flash location.
