* lib_ppc: rework the flush_cacheDave Liu2008-12-15-19/+17
| | | | | | | | | | - It is possible to miss flush/invalidate the last cache line, we fix it at here. - add the volatile and memory clobber. They are pointed by Scott Wood. Signed-off-by: Dave Liu <daveliu@freescale.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.

* bootm: support subcommands in linux ppc bootmKumar Gala2008-10-29-96/+175
| | | | | | Add support for 'bdt', 'cmdline', 'prep' to the linux PPC bootm. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* 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>

* Adds two more ethernet interface to 83xxrichardretanubun2008-10-18-0/+30
| | | | | | | | | Added as a convenience for other platforms that uses MPC8360 (has 8 UCC). Six eth interface is chosen because the platform I am using combines UCC1&2 and UCC3&4 as 1000 Eth and the other four UCCs as 10/100 Eth.

* Do not init SATA when disabled on 8536DS.Jason Jin2008-10-14-2/+14
| | | | | | | | | | SGMII and SATA share the serdes on MPC8536 CPU, When SATA disabled and the driver still try to access the SATA registers, the cpu will hangup. This patch try to fix this by reading the serdes status before the SATA initialize. Signed-off-by: Jason Jin <Jason.jin@freescale.com> Acked-by: Andy Fleming <afleming@freescale.com>
* fdt: Overwrite /chosen node in bootm if it already exists in the dtbStefan Roese2008-10-01-1/+1
| | | | | | | | Set force parameter in fdt_chosen() call in do_bootm_linux() call. Without this, the chosen node is not overwritten if it already exists. Signed-off-by: Stefan Roese <sr@denx.de>
* 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).

* lib_ppc/interrupts.c: make board_show_activity() a weak functionWolfgang Denk2008-09-09-1/+6
| | | | | | | This allows to use show_activity() without having to define an empty board_show_activity() function. Signed-off-by: Wolfgang Denk <wd@denx.de>
* 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. Also, remove passing in cmd_tbl_t as its not needed by the OS boot functions. flag isn't currently used but might be in the future so we left it alone. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* fdt: refactor initrd related codeKumar Gala2008-08-26-26/+2
| | | | | | | | | Created a new fdt_initrd() to deal with setting the initrd properties in the device tree and fixing up the mem reserve. We can use this both in the choosen node handling and lets us remove some duplicated code when we fixup the initrd info in bootm on PPC. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* fdt: refactor fdt resize codeKumar Gala2008-08-26-28/+4

* bootm: move lmb into the bootm_headers_t structureKumar Gala2008-08-26-1/+1
| | | | | | | | To allow for persistent state between future bootm subcommands we need the lmb to exist in a global state. Moving it into the bootm_headers_t allows us to do that. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* bootm: refactor fdt locating and relocation codeKumar Gala2008-08-26-484/+8

* bootm: refactor ramdisk locating codeKumar Gala2008-08-26-11/+5
| | | | | | | | Move determing if we have a ramdisk and where its located into the common code. Keep track of the ramdisk start and end in the bootm_headers_t image struct. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* Consolidate strmhz() implementationHaavard Skinnemoen2008-08-21-13/+0
| | | | | | | | | | ARM, i386, m68k and ppc all have identical implementations of strmhz(). Other architectures don't provide this function at all. This patch moves strmhz() into lib_generic, reducing code duplication and providing a more unified API across architectures. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
* Update linux bootm to support ePAPR client interfaceKumar Gala2008-08-19-10/+23
| | | | | | | | The ePAPR spec has some subtle differences from the current device tree based boot interface to the powerpc linux kernel. The powerpc linux kernel currently ignores the differences that ePAPR specifies. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* NAND boot: MPC8313ERDB supportScott Wood2008-08-12-2/+2
| | | | | | | | | Note that with older board revisions, NAND boot may only work after a power-on reset, and not after a warm reset. I don't have a newer board to test on; if you have a board with a 33MHz crystal, please let me know if it works after a warm reset. Signed-off-by: Scott Wood <scottwood@freescale.com>
* Fix fallout from autostart revertKumar Gala2008-08-12-4/+1

* Fix printf errors.Andrew Klossner2008-07-09-4/+4
| | | | | | | | | | | | The compiler will help find mismatches between printf formats and arguments if you let it. This patch adds the necessary attributes to declarations in include/common.h, then begins to correct the resulting compiler warnings. Some of these were bugs, e.g., "$d" instead of "%d" and incorrect arguments. Others were just annoying, like int-long mismatches on a system where both are 32 bits. It's worth fixing the annoying errors to catch the real ones. Signed-off-by: Andrew Klossner <andrew@cesa.opbu.xerox.com>

* Resize device tree to allow space for board changes and the chosen nodeAndy Fleming2008-06-28-8/+58
| | | | | | | | | | | | | Current code requires that a compiled device tree have space added to the end to leave room for extra nodes added by board code (and the chosen node). This requires that device tree creators anticipate how much space U-Boot will add to the tree, which is absurd. Ideally, the code would resize and/or relocate the tree when it needed more space, but this would require a systemic change to the fdt code, which is non-trivial. Instead, we resize the tree inside boot_relocate_fdt, reserving either the remainder of the bootmap (in the case where the fdt is inside the bootmap), or adding CFG_FDT_PAD bytes to the size.

* Change lmb to use phys_size_t/phys_addr_tBecky Bruce2008-06-12-7/+9

In the future we will move to doing more "dynamic" LAW allocation since the majority of users dont really care about what LAW number they are at.
