* 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>
* Move architecture specific config.mk files into subdirsPeter Tyser2009-07-21-0/+41
| | | | | | | | This cleans up U-Boot's toplevel directory a bit and makes the architecture 'config.mk' file naming and location similar to board and cpu 'config.mk' files Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* stdio/device: rework function naming conventionJean-Christophe PLAGNIOL-VILLARD2009-07-18-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* 85xx/86xx: Ensure MP boot page is not usedKumar Gala2009-04-01-0/+15
| | | | | | | | | | | We had a bug on 86xx in which the boot page used to bring up secondary cores was being overwritten and used for the malloc region in u-boot. We need to reserve the region of memory that the boot page is going to be put at so nothing uses it.

* 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>
* boards: get mac address from env and move load_sernum_ethaddr() to board initMike Frysinger2009-03-20-6/+0
| | | | | | | | | | | | | | | | | | | 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. The boards that get converted here are: - kup4k/kup4x - pcs440ep - tqm8xx Signed-off-by: Mike Frysinger <vapier@gentoo.org> CC: Ben Warren <biggerbadderben@gmail.com> CC: Stefan Roese <sr@denx.de>

| | | | | | | | | | | | 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 the common ppc code have board-specific hooks, move the board_get_enetaddr() function into the board-specific init functions.

* nx823: get mac address from environmentMike Frysinger2009-03-20-4/+0
| | | | | | | | | | | | | 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. For the nx823, the serial number is moved out of load_sernum_ethaddr() and into misc_init_r() as is the env setup. This lets us kill off the former function in the process.

* Add MMC FrameworkAndy Fleming2009-02-16-0/+9
| | | | | | | | | | | | | | Here's a new framework (based roughly off the linux one) for managing MMC controllers. It handles all of the standard SD/MMC transactions, leaving the host drivers to implement only what is necessary to deal with their specific hardware. This also hooks the infrastructure into the PowerPC board code (similar to how the ethernet infrastructure now hooks in) Some of this code was contributed by Dave Liu <daveliu@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
* ppc: Fix roll over bug in flush_cache()Kumar Gala2009-02-10-2/+4
| | | | | | | | If we call flush_cache(0xfffff000, 0x1000) it would never terminate the loop since end = 0xffffffff and we'd roll over our counter from 0xfffffe0 to 0 (assuming a 32-byte cache line) Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* ppc: Move CONFIG_MAX_MEM_MAPPED to common config.hKumar Gala2009-02-10-3/+0

* SATA: do not auto-initialize during bootMike Frysinger2009-01-27-20/+0
| | | | | | | | | | | | 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().

* 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.

* bootm: Add subcommandsKumar Gala2008-10-29-0/+3
| | | | | | | | | | | | | | Add the ability to break the steps of the bootm command into several subcommands: start, loados, ramdisk, fdt, bdt, cmdline, prep, go. This allows us to do things like manipulate device trees before they are passed to a booting kernel or setup memory for a secondary core in multicore situations. Not all OS types support all subcommands (currently only start, loados, ramdisk, fdt, and go are supported). Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* Added arch_lmb_reserve to allow arch specific memory regions protectionKumar Gala2008-10-18-22/+28
| | | | | | | | | Each architecture has different ways of determine what regions of memory might not be valid to get overwritten when we boot. This provides a hook to allow them to reserve any regions they care about. Currently only ppc, m68k and sparc need/use this. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* powerpc: Fix bootm to boot up again with a RamdiskHeiko Schocher2008-09-13-2/+3
| | | | | | | | | | | | | | | Commit 2a1a2cb6 didnt remove the dummy mem reservation in fdt_chosen, and this stopped Linux from booting with a Ramdisk. This patch fixes this, by deleting the useless dummy mem reservation. When booting with a Ramdisk, a fix offset FDT_RAMDISK_OVERHEAD is now added to of_size, so we dont need anymore a dummy mem reservation. I measured the value of FDT_RAMDISK_OVERHEAD on a MPC8270 based system (=0x44 bytes) and rounded it up to 0x80).

* bootm: refactor do_reset and os boot function argsKumar Gala2008-08-26-7/+4
| | | | | | | | | | | | There is no need for each OS specific function to call do_reset() we can just do it once in bootm. This means its feasible on an error for the OS boot function to return.
