* fdt: Pass the device serial number through devicetreePaul Kocialkowski2015-06-05-0/+25
| | | | | | | | | | | | | | | | Before device-tree, the device serial number used to be passed to the kernel using ATAGs (on ARM). This is now deprecated and all the handover to the kernel should now be done using device-tree. Thus, this passes the serial-number property to the kernel using the serial-number property of the root node, as expected by the kernel. The serial number is a string that somewhat represents the device's serial number. It might come from some form of storage (e.g. an eeprom) and be programmed at factory-time by the manufacturer or come from identification bits available in e.g. the SoC.

* | fdt: Fix regression in fdt_pack_reg()Hans de Goede2014-12-01-6/+6
|/ | | | | | | | | | | | | | | | | After commit 933cdbb479: "fdt: Try to use fdt_address_cells()/fdt_size_cells()" I noticed that allwinner boards would no longer boot. Switching to fdt_address_cells / fdt_size_cells changes the result from bytes to 32 bit words, so when we increment pointers into the blob, we must do so by 32 bit words now. This commit makes allwinner boards boot again.

The first user of this will be the sunxi display code. lcd_dt_simplefb_configure_node is also a good candidate to be converted to use this, but that requires someone to run some tests first, as lcd_dt_simplefb_configure_node does not honor #address-cells and #size-cells, but simply assumes 1 and 1 for both.

| | | | | | | | | | | | | | | | | | | 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: Add new fdt_create_phandle helperKumar Gala2011-09-29-0/+20
| | | | | | | | Add a helper function that will return a phandle value for the given node. If the node doesn't have a phandle already one will be created. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: Gerald Van Baren <vanbaren@cideas.com>
* fdt: Rename fdt_create_phandle to fdt_set_phandleKumar Gala2011-09-29-3/+3
| | | | | | | | The old fdt_create_phandle didn't actually create a phandle it just set one. We'll introduce a new helper that actually does creation. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: Gerald Van Baren <vanbaren@cideas.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
| | | | | | | | | | | | | Introduce two functions, fdt_verify_alias_address() and fdt_get_base_address(), which can be used to verify the physical address of a device in a device tree. fdt_get_base_address() returns the base address of an SOC or PCI node. fdt_verify_alias_address() prints a message if the address of a node specified by an alias does not match the given physical address.
