* General help message cleanupWolfgang Denk2009-06-12-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many of the help messages were not really helpful; for example, many commands that take no arguments would not print a correct synopsis line, but "No additional help available." which is not exactly wrong, but not helpful either. Commit ``Make "usage" messages more helpful.'' changed this partially. But it also became clear that lots of "Usage" and "Help" messages (fields "usage" and "help" in struct cmd_tbl_s respective) were actually redundant. This patch cleans this up - for example: Before: => help dtt dtt - Digital Thermometer and Thermostat Usage: dtt - Read temperature from digital thermometer and thermostat. After: => help dtt dtt - Read temperature from Digital Thermometer and Thermostat Usage: dtt Signed-off-by: Wolfgang Denk <wd@denx.de>

* powerpc: Fix bootm to boot up again with a RamdiskHeiko Schocher2008-09-13-1/+2
| | | | | | | | | | | | | | | 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).

* bootm: Set working fdt address as part of the bootm flowKumar Gala2008-08-26-1/+13
| | | | | | | | Set the fdt working address so "fdt FOO" commands can be used as part of the bootm flow. Also set an the environment variable "fdtaddr" with the value. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* Add note on dereferencing /aliases pointersGerald Van Baren2008-08-24-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace the "must quote special characters" note with a hint on how to dereference /aliases pointers by omitting the leading "/". This feature was introduced by Kumar Gala as a libfdt enhancement in commit ed035708235332c3c117ee3bb1a426063f03cfcb. Example: => fdt print /aliases aliases { ethernet0 = "/qe@e0100000/ucc@2000"; ethernet1 = "/qe@e0100000/ucc@3000"; serial0 = "/soc8360@e0000000/serial@4500"; serial1 = "/soc8360@e0000000/serial@4600"; pci0 = "/pci@e0008500"; }; => fdt print ethernet0 ucc@2000 { device_type = "network"; compatible = "ucc_geth"; cell-index = <0x1>; reg = <0x2000 0x200>; interrupts = <0x20>; interrupt-parent = <0x2>; local-mac-address = [00 00 00 00 00 00]; rx-clock-name = "none"; tx-clock-name = "clk9"; phy-handle = <0x3>; phy-connection-type = "rgmii-id"; pio-handle = <0x4>; }; Signed-off-by: Gerald Van Baren <vanbaren@cideas.com>

* Fix printf errors.Andrew Klossner2008-07-09-4/+4
| | | | | | | | | | | | 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>
* libfdt: Move the working_fdt pointer to cmd_fdt.cGerald Van Baren2008-06-10-0/+5
| | | | | | | | 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>

* The fdt boardsetup command criteria was not uniqueGerald Van Baren2008-06-09-1/+2

* Big white-space cleanup.Wolfgang Denk2008-05-21-2/+2
| | | | | | | | | | | This commit gets rid of a huge amount of silly white-space issues. Especially, all sequences of SPACEs followed by TAB characters get removed (unless they appear in print statements). Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de>
* Fix fdt set command to conform to dts specAndy Fleming2008-04-02-70/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The fdt set command was treating properties specified as <00> and <0011> as byte streams, rather than as an array of cells. As we already have syntax for expressing the desire for a stream of bytes ([ xx xx ...]), we should use the <> syntax to describe arrays of cells, which are always 32-bits per element. If we imagine this likely (IMHO) scenario: > fdt set /ethernet-phy@1 reg <1> With the old code, this would create a bad fdt, since the reg cell would be made to be one byte in length. But the cell must be 4 bytes, so this would break mysteriously. Also, the dts spec calls for constants inside the angle brackets (<>) to conform to C constant standards as they pertain to base. Take this scenario: > fdt set /ethernet@f00 reg <0xe250000\ 0x1000> The old fdt command would complain that it couldn't parse that. Or, if you wanted to specify that a certain clock ran at 33 MHz, you'd be required to do this: > fdt set /mydev clock <1f78a40> Whereas the new code will accept decimal numbers. While I was in there, I extended the fdt command parser to handle property strings which are split across multiple arguments: > fdt set /ethernet@f00 interrupts < 33 2 34 2 36 2 > > fdt p /ethernet@f00 ethernet@f00 { interrupts = <0x21 0x2 0x22 0x2 0x24 0x2>; }; Lastly, the fdt print code was rearranged slightly to print arrays of cells if the length of the property is a multiple of 4 bytes, and to not print leading zeros.

* Remove deprecated CONFIG_OF_HAS_UBOOT_ENV and CONFIG_OF_HAS_BD_TJerry Van Baren2008-03-26-17/+0
| | | | | | | | | | | | | | 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>

* Call ft_board_setup() from the bootm command.Gerald Van Baren2007-08-10-7/+0
| | | | | | | | | | In the patch titled "Create new fdt boardsetup command..."

* Create new fdt boardsetup command, fix bug parsing [] form of set values.Gerald Van Baren2007-08-10-10/+21
| | | | | | | | | | | | 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.

The fdt command uses David Gibson's libfdt library to manipulate as well as print the flattened device tree. This patch is the new command, the second part is the modifications to the existing code.
