* Fix constness of the fdt void pointer in fdt_getprop_u32_defaultGabe Black2011-11-13-2/+2
| | | | | | | The function fdt_getprop_u32_default doesn't modify the fdt, so it can use a const void * for its fdt argument. Signed-off-by: Gabe Black <gabeblack@chromium.org>
* Add some missing endian conversions in fdt_support.cGabe Black2011-11-13-2/+2
| | | | | | | | | | Some functions in fdt_support.c use fdt_getprop to read 32 bit values out of the device tree, but then use them directly without doing any endian conversion. Because they check for a value that doesn't actually appear in practice, the functions continued to work even though they're incorrect. This change adds the missing conversions.

* fdt: Add new fdt_set_node_status & fdt_set_status_by_alias helpersShengzhou Liu2011-10-18-1/+59
| | | | | | | | | | | | | | | | | | | | | | | | Add common function fdt_set_node_status() to assist in various locations that we set a nodes status. This function utilizes the status values that are part of the EPAPR spec (on power.org). fdt_set_status_by_alias() is based on fdt_set_node_status() but uses an alias string to identify the node to update. 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.

* fdt: check for fdt errors in fdt_create_phandleTimur Tabi2011-10-15-2/+9
| | | | | | | | | fdt_create_phandle() was ignoring errors from fdt_set_phandle(). If an error occurs, print an error message and return 0, which is an invalid phandle. We also need to change the return type for fdt_create_phandle() to indicate that it cannot return an error code. Signed-off-by: Timur Tabi <timur@freescale.com>

* fdt: introduce fdt_create_phandle()Gerald Van Baren2011-07-14-0/+40
| | | | | | | | | | | The ePAPR specification says that phandle properties should be called "phandle", and not "linux,phandle". 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>
* fdt: introduce fdt_verify_alias_address() and fdt_get_base_address()Timur Tabi2011-07-14-0/+67

| | | | | | | | | | | | This patch fixes a bug in fdt_fixup_nor_flash_node() when the reg property has multiple reg tuples, like: reg = <0 0x00000000 0x04000000 0 0x04000000 0x04000000>; In this case this function did not update the reg property correctly. Signed-off-by: Stefan Roese <sr@denx.de>
* 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.
