* ppc: Loose GOT access in IRQJoakim Tjernlund2010-01-26-0/+50
| | | | | | | | Using the GOT in IRQ handlers requires r14 to be -ffixed-r14. Avoid this by relocatate transfer_to_handler too. This will allow to free up r14 later on. Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se>
* mpc512x: Add display of reset status registerDetlev Zundel2010-01-24-3/+4
| | | | | | | | Content of the RSR is put into gd early so we can output it together with the CPU info. The clearing of gd in board_init_f is redundant for this architecture as it is done in cpu_init_f so we remove it. Signed-off-by: Detlev Zundel <dzu@denx.de>

| * | Generic udelay() with watchdog supportIngo van Lil2009-12-05-13/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the PPC reference implementation the udelay() function is responsible for resetting the watchdog timer as frequently as needed. Most other architectures do not meet that requirement, so long-running operations might result in a watchdog reset. This patch adds a generic udelay() function which takes care of resetting the watchdog before calling an architecture-specific __udelay(). Signed-off-by: Ingo van Lil <inguin@gmx.de>
* | | mpc85xx, mpc86xx: Fix gd->cpu pointer after relocationPeter Tyser2009-12-15-0/+8
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* mpc85xx: Fix booting on various boardsAnton Vorontsov2009-10-16-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* ppc: Check for compilers that don't support relocationPeter Tyser2009-10-03-0/+6
| | | | | | | | | | Certain ppc compilers are known not to generate the .fixup section properly. The .fixup section is necessary to create a relocatable U-Boot image. A basic check for the existence of the .fixup section should hopefully catch the majority of broken compilers which don't support relocation. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* ppc: Enable full relocation to RAMPeter Tyser2009-10-03-0/+1
| | | | | | | | | | | | | The following changes allow U-Boot to fully relocate from flash to RAM: - Remove linker scripts' .fixup sections from the .text section - Add -mrelocatable to PLATFORM_RELFLAGS for all boards - Define CONFIG_RELOC_FIXUP_WORKS for all boards Previously, U-Boot would partially relocate, but statically initialized pointers needed to be manually relocated.

* push LOAD_ADDR out to arch mk filesMike Frysinger2009-09-04-0/+2
| | | | | | | | | | Rather than maintain/extend the current ifeq($(ARCH)) mess that exists in the standalone Makefile, push the setting up of LOAD_ADDR out to the arch config.mk (and rename to STANDALONE_LOAD_ADDR in the process).

* ppc: Unlock cache-as-ram in a consistent mannerPeter Tyser2009-07-23-12/+3
| | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Roese2009-06-12-4/+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.

* ppc: mark global bi_enet*addr as legacyMike Frysinger2009-03-20-47/+7
| | | | | | | | | | | | | | | 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>

* lib_ppc: Move trap_init to occur earlierBecky Bruce2008-11-10-5/+5
| | | | | | | | | | | 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.
