2008-06-10libfdt: Move the working_fdt pointer to cmd_fdt.cGerald Van Baren
The working_fdt pointer was declared in common/fdt_support.c but was not used there. Move it to common/cmd_fdt.c where it is used (it is also used in lib_ppc/bootm.c). Signed-off-by: Gerald Van Baren <vanbaren@cideas.com>
2008-06-10fdt: unshadow global working fdt variableKim Phillips
differentiate with local variables of the same name by renaming the global 'fdt' variable 'working_fdt'. Signed-off-by: Kim Phillips <kim.phillips@freescale.com>
2008-03-2583xx/fdt_support: let user specifiy FSL USB Dual-Role controller roleAnton Vorontsov
Linux understands "host" (default), "peripheral" and "otg" (broken). Though, U-Boot doesn't restrict dr_mode variable to these values (think of renames in future). Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Kim Phillips <kim.phillips@freescale.com>
2008-03-26Remove deprecated CONFIG_OF_HAS_UBOOT_ENV and CONFIG_OF_HAS_BD_TJerry Van Baren
These defines embedded the u-boot env variables and/or the bd_t structure in the fdt blob. The conclusion of discussion on the u-boot email list was that embedding these in the fdt blob is not useful: there are better ways of passing the data (in fact, the fdt blob itself replaces the bd_t struct). The only board that enables these is the stxxtc and they don't appear to be used by linux. Signed-off-by: Gerald Van Baren <vanbaren@cideas.com> Acked-by: Kim Phillips <kim.phillips@freescale.com>

2008-02-12QE: Move FDT support into a common fileKumar Gala
Move the flat device tree setup for QE related devices into a common file shared between 83xx & 85xx platforms that have QE's. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2008-01-0985xx: add ability to upload QE firmwareTimur Tabi
Define the layout of a binary blob that contains a QE firmware and instructions on how to upload it. Add function qe_upload_firmware() to parse the blob and perform the actual upload. Add command-line command "qe fw" to take a firmware blob in memory and upload it. Update ft_cpu_setup() on 85xx to create the 'firmware' device tree node if U-Boot has uploaded a firmware. Fully define 'struct rsp' in immap_qe.h to include the actual RISC Special Registers. Signed-off-by: Timur Tabi <timur@freescale.com>
2008-01-08Fine grained per property /chosen updating.Gerald Van Baren
Implement a suggestion by Scott Wood to make the /chosen handling fine grained. Don't overwrite pre-existing properties on a per-property basis, so if /chosen exists but a necessary /chosen/property doesn't, it gets created. If a /chosen property exists, it is NOT overwritten unless the "force" flag is true. Signed-off-by: Gerald Van Baren <vanbaren@cideas.com>
2007-12-07Conditionally compile fdt_fixup_ethernet()Gerald Van Baren
Fix compiler warnings: On boards that don't have ethernets defined, don't compile fdt_fixup_ethernet().
2007-12-07Added fdt_fixup_stdout that uses aliases to set linux,stdout-pathKumar Gala
We use a combination of the serialN alias and CONFIG_CONS_INDEX to determine which serial alias we should set linux,stdout-path to. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-12-07Add common memory fixup functionKumar Gala
Add the function fdt_fixup_memory() to fixup the /memory node of the fdt Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-12-07Conditionally compile fdt_support.cKumar Gala
Modify common/Makefile to conditionally compile fdt_support.c based on CONFIG_OF_LIBFDT. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-11-21Add additional fdt fixup helper functionsKumar Gala
Added the following fdt fixup helpers: * do_fixup_by_prop{_u32} - Find matching nodes by property name/value * do_fixup_by_compat{_u32} - Find matching nodes by compat The _u32 variants work the same only the property they are setting is know to be a 32-bit integer instead of a byte buffer. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-11-21Add fdt_fixup_ethernet helper to set mac addressesKumar Gala
Added a fixup helper that uses aliases to set mac addresses in the device tree based on the bd_t Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-11-21Update libfdt from device tree compiler (dtc)Kumar Gala
Update libfdt to commit 8eaf5e358366017aa2e846c5038d1aa19958314e from the device tree compiler (dtc) project. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-11-21Move do_fixup* for libfdt into common codeKumar Gala
Moved the generic fixup handling code out of cpu/mpc5xxx and cpu/mpc8260 into common/fdt_support.c and renamed: do_fixup() -> do_fixup_by_path() do_fixup_u32() -> do_fixup_by_path_u32() Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-11-21Removed some nonused fdt functions and moved fdt_find_and_setprop out of libfdtKumar Gala
Removed: fdt_node_is_compatible fdt_find_node_by_type fdt_find_compatible_node To ease merge of newer libfdt as we aren't using them anywhere at this time. Also moved fdt_find_and_setprop out of libfdt into fdt_support.c for the same reason. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2007-08-10Create new fdt boardsetup command, fix bug parsing [] form of set values.Gerald Van Baren
Previously ft_board_setup() was called by fdt_chosen() which was not really correctly structured. This splits ft_board_setup() out by creating a new fdt boardsetup command. Fix a bug when parsing fdt set command values which have the square bracket form [00 11 22 33] - the length was updated incorrectly in when parsing that form.

2007-08-10Fix fdt_chosen() to call ft_board_setup(), clean up long lines.Gerald Van Baren
The fdt_chosen() function was adding/seting some properties ad-hoc improperly and duplicated (poorly) what was done in ft_board_setup() Clean up long lines (setting properties, printing errors). Signed-off-by: Gerald Van Baren <vanbaren@cideas.com>
2007-08-10Replace fdt_node_offset() with fdt_find_node_by_path().Gerald Van Baren
The new name matches more closely the kernel's name, which is also a much better description. Signed-off-by: Wolfgang Grandegger <wg@grandegger.com> Acked-by: Gerald Van Baren <vanbaren@cideas.com>
2007-08-10Minor code clean up.Gerald Van Baren
Declare the variable fdt properly as extern. Call the "set_fn" function pointer the "short way" without the full dereferencing syntax. Signed-off-by: Gerald Van Baren <vanbaren@cideas.com>
2007-08-10Improve error messages, more informative.Gerald Van Baren
Print more than the raw libfdt error message strings. This is especially useful for cluing in the user when the bootm command aborts due to blob problems. Signed-off-by: Gerald Van Baren <vanbaren@cideas.com>
2007-04-19Fix serious pointer bug with bootm and reserve map.Gerald Van Baren
What was suppose to be a stack variable was declared as a pointer, overwriting random memory. Also moved the libfdt.a requirement into the main Makefile. That is The U-Boot Way.
2007-04-14Improve the bootm command for CONFIG_OF_LIBFDTGerald Van Baren
In bootm, create the "/chosen" node only if it doesn't already exist (better matches the previous behavior). Update for proper reserved memory map handling for initrd.
2007-04-06Moved fdt command support code to fdt_support.cGerald Van Baren
...in preparation for improving the bootm command's handling of fdt blobs. Also cleaned up some coding sloppiness.
