* fdt_support.c: Correct linux,initrd-start/end settingTom Rini2014-01-20-2/+2
| | | | | | | | | | | The change to add 64bit initrd support broke 32bit initrd support as it always set 64bits worth of data into the properties, even on 32bit systems. The fix is to use addr_cell_len (which already says how much data is in 'tmp') to set the property, rather than always setting 8. Thanks to Stephen Warren for pointing out the fix here.

* fdt: remove unaligned access in fdt_fixup_ethernet()Stephen Warren2013-06-07-1/+2
| | | | | | | | | | | | | | | Some ARM compilers may emit code that makes unaligned accesses when faced with constructs such as: char mac[16] = "ethaddr"; Replace this with a strcpy() call instead to avoid this. strcpy() is used here, rather than replacing all usage of the mac variable with the string itself, since the loop itself sprintf()s to the variable each iteration, so strcpy() is doing basically the same thing.

* fdt_support: Use CONFIG_NR_DRAM_BANKS if definedDoug Anderson2013-05-17-0/+4
| | | | | | | | | It appears that there are some cases where we have more than 4 banks of memory. Use CONFIG_NR_DRAM_BANKS if it's defined to handle this.

We also add some shortcut functions to help the common cases of setting "okay" and "disabled": fdt_status_okay() fdt_status_disabled() fdt_status_okay_by_alias() fdt_status_disabled_by_alias() Finally, we fixup the corenet_ds ethernet code which previously had a function by the same name that can be replaced with the new helpers.

* fdt: update fdt_alloc_phandle to use fdt_get_phandleTimur Tabi2011-10-15-5/+2
| | | | | | | | | | | | | | | | | | | The device tree compiler, dtc, can use "phandle" and/or "linux,phandle" properties to specify the phandle for any node. By default, it uses both, but "linux,phandle" is deprecated. One day, we'd like to stop using "linux,phandle", but U-boot needs to support both properties equally first. fdt_alloc_phandle() generates a unique phandle, but it was only checking the "linux,phandle" properties. Instead, we use fdt_get_phandle(), which checks both properties automatically. This ensures that we support dtbs that only use "phandle". The side-effect is that fdt_alloc_phandle() now takes twice as long, since it has to check for two properties instead of one in each node that it searches.

To facilitate the migration from "linux,phandle" to "phandle", introduce function fdt_create_phandle(), which creates a phandle in a given node. For now, we create both the "phandle" and "linux,phandle" properties. A later version of this function will remove support for "linux,phandle". Signed-off-by: Timur Tabi <timur@freescale.com>

* ppc4xx/fdt/flash: Change fdt_fixup_nor_flash_node() to not rely on cs sizeStefan Roese2010-09-23-10/+41
| | | | | | | | | | | | | | | | | | | | | | This patch changes the behaviour of the fdt_fixup_nor_flash_node() function. Now it doesn't patch the size of the "reg" property with the chip-select size, but with the size returned from the new function flash_get_bank_size(). This function will return per weak default the flash size of the bank (bank = chip-select numer) detected by the flash driver. If this does not fit your needs, this function may be overridden by a board specific one. For this the parameters needed to be changed. So I intentionally squashed the PPC4xx stuff using this routine into this patch. Otherwise it would not be git-bisectable anymore. The board specific function for the AMCC/APM Ebony eval board is now included in this patch version.

* fdt: call fdt_parent_offset fewer times while translating addressesScott Wood2010-08-19-37/+21
| | | | | | | | | | | | | | | fdt_parent_offset() is an expensive operation, so we'd like to reduce unnecessary calls to it. Further, the practice of iterating up to the root if address/size cells aren't found was apparently done for Linux for compatibility with certain buggy Open Firmware implementations, and U-Boot inherited the code. The compliant behavior is to treat a missing #address-cells as 2, and a missing #size-cells as 1 -- never looking anywhere but the immediate parent of the node of interest.

* fdt: Fix bug in size calculation in fdt_resize() with initrd useFeng Wang2010-08-09-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Original bug description from Feng (fdt_resize() bug caused "WARNING: could not set linux, initrd-start FDT_ERR_NOSPACE."): What I got is an error: "WARNING: could not set linux,initrd-start FDT_ERR_NOSPACE." after loading Device Tree blob. This in turn caused linux to miss init part. After some digging, I found out the reason for this error, it is caused by fdt_resize(). FDT blob got resized after filling in all board specific information of PowerPC. (in boot_body_linux()). It reduced blob size with only extra space for two fdt_reserve_entry, one for fdt itself, and one for initrd. Then it's aligned to a 0x1000 page boundary. However, later in fdt_initrd(), it could add two more properties, initrd-start AND initrd-end, each one needs at least two fdt_reserve_entry sizes done by _fdt_add_property() (name and value). Thus, the two fdt_reserve_entry extra space is not sufficient. So for some specific fdt size which is just under the page boundary after resizing, this will cause an error of FDT_ERR_NOSPACE in fdt_initrd() when setting those two properties, and failed to pass initrd information to linux. My fix is in fdt_resize(), leave at least 4 fdt_reserve_entry for initrd. So instead of 2*sizeof(struct fdt_reserve_entry) for actual_totalsize, use 5*sizeof(struc fdt_reserve_entry). Stefan: I got this same error on katmai, when trying to boot with initrd (run flash_self). This patch fixes this issue.

| | | | | | | | | Allow overwriting defined partitions in the device tree blob using partition info defined in the 'mtdparts' environment variable. Signed-off-by: Anatolij Gustschin <agust@denx.de> Cc: Gerald Van Baren <vanbaren@cideas.com>
* fdt_support: Add multi-serial support for stdout fixupAnton Vorontsov2009-10-26-1/+21
| | | | | | | | | | | | Currently fdt_fixup_stdout() is using hard-coded CONFIG_CONS_INDEX constant. With multi-serial support, the CONS_INDEX may no longer represent actual console, so we should try to extract port number from the current stdio device name instead of always hard-coding the constant value.

* fdt: Fix fdt padding issue for initrd mem_rsvKumar Gala2009-10-24-2/+3
| | | | | | | | | | | | | Its possible that we end up with a device tree that happens to be a particular size that after we call fdt_resize() we don't have any space left for the initrd mem_rsv. Fix this be adding a second mem_rsv into the size calculation. We had one to cover the fdt itself and we have the potential of adding a second for the initrd.

* fdt: Add fdt_fixup_nor_flash_size() to fixup NOR FLASH size in dtbStefan Roese2009-10-23-0/+44
| | | | | | | | | | This function can be used to update the size in the "reg" property of the NOR FLASH device nodes. This is necessary for boards with non-fixed NOR FLASH sizes.

* fdt: Fix fdt_pci_dma_ranges handling of 64-bit rangesKumar Gala2009-08-09-2/+2
| | | | | | | | | | If the size of a region equal to 4G it can't be represnted in a 32-bit BAR so we should have marked that case as MEM64. Additionally bump the number of inbound windows up to 4 to handle the fact that Freescale PPCs that have an implicit window for CCSRBAR. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* 83xx: Replace CONFIG_MPC83XX with CONFIG_MPC83xxPeter Tyser2009-06-12-2/+2
| | | | | | | | Use the standard lowercase "xx" capitalization that other Freescale architectures use for CPU defines to prevent confusion and errors Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Kim Phillips <kim.phillips@freescale.com>
* pci: Rename PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY for clarityKumar Gala2009-02-07-2/+2
| | | | | | | | | | The PCI_REGION_MEMORY and PCI_REGION_MEM are a bit to similar and can be confusing when reading the code. Rename PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY to clarify its used for system memory mapping purposes. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* fdt_resize(): fix actualsize calculations with unaligned blobsPeter Korsgaard2009-01-17-1/+1
| | | | | | | | | | | | | The code in fdt_resize() to extend the fdt size to end on a page boundary is wrong for fdt's not located at an address aligned on a page boundary. What's even worse, the code would make actualsize shrink rather than grow if (blob & 0xfff) was bigger than the amount of padding added by ALIGN(), causing fdt_add_mem_rsv to fail. Fix it by aligning end address (blob + size) to a page boundary instead. For aligned fdt's this is equivalent to what we had before. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
* fdt_resize(): ensure minimum paddingPeter Korsgaard2008-10-30-2/+5
| | | | | | | | | fdt_add_mem_rsv() requires space for a struct fdt_reserve_entry (16 bytes), so make sure that fdt_resize at least adds that much padding, no matter what the location or size of the fdt is.

* fdt: Added helper to set PCI dma-ranges propertyKumar Gala2008-10-24-0/+69
| | | | | | | | | | | Added fdt_pci_dma_ranges() that parses the pci_region info from the struct pci_controller and populates the dma-ranges based on it. The max # of windws/dma-ranges we support is 3 since on embedded PowerPC based systems this is the max number of windows.
