2008-10-18Added arch_lmb_reserve to allow arch specific memory regions protectionKumar Gala
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>

2008-10-18Adds two more ethernet interface to 83xxrichardretanubun
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.

2008-10-14Do not init SATA when disabled on 8536DS.Jason Jin
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>
2008-10-01fdt: Overwrite /chosen node in bootm if it already exists in the dtbStefan Roese
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>
2008-09-13powerpc: Fix bootm to boot up again with a RamdiskHeiko Schocher
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).

2008-08-26bootm: refactor do_reset and os boot function argsKumar Gala
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.

2008-08-26fdt: refactor initrd related codeKumar Gala
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>
2008-08-26fdt: refactor fdt resize codeKumar Gala

2008-08-26bootm: move lmb into the bootm_headers_t structureKumar Gala
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>
2008-08-26bootm: refactor fdt locating and relocation codeKumar Gala

2008-08-21Consolidate strmhz() implementationHaavard Skinnemoen
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>
2008-08-19Update linux bootm to support ePAPR client interfaceKumar Gala
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>
2008-08-12NAND boot: MPC8313ERDB supportScott Wood
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>

2008-07-09Fix printf errors.Andrew Klossner
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>

2008-06-28Resize device tree to allow space for board changes and the chosen nodeAndy Fleming
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.

2008-06-12Change lmb to use phys_size_t/phys_addr_tBecky Bruce

2008-06-11FSL LAW: Keep track of LAW allocationsKumar Gala
Make it so we keep track of which LAWs have allocated and provide a function (set_next_law) which can allocate a LAW for us if one is free. 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. Also, add CONFIG_MPC8540 or CONFIG_MPC8560 to those boards which needed them Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Signed-off-by: Andy Fleming <afleming@freescale.com>

2008-06-03PPC: Change lib_ppc/bat_rw.c to use high batsBecky Bruce

2008-04-29ppc flush_cache: add watch-dog triggering into the loops.Yuri Tikhonov
Some boards (e.g. lwmon5) need rather a frequent watch-dog kicking. Since the time it takes for the flush_cache() function to complete its job depends on the size of data being flushed, one may encounter watch-dog resets on such boards when, for example, download big files over ethernet.

2008-04-17Restore the ability to continue booting after legacy image overwriteMarian Balakowicz
Before new uImage code was merged, bootm code allowed for the kernel image to get overwritten during decompresion. new uImage introduced a check for image overwrites and refused to boot the image that got overwritten. This patch restores the old behavior. It also adds a warning when the image overwriten is a multi-image file, because in such case accessing componentes other than the first one will fail.
