* powerpc: Fix bootm to boot up again with a RamdiskHeiko Schocher2008-09-13-3/+1
| | | | | | | | | | | | | | | 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).

* fdt: refactor initrd related codeKumar Gala2008-08-26-42/+67
| | | | | | | | | Created a new fdt_initrd() to deal with setting the initrd properties in the device tree and fixing up the mem reserve. We can use this both in the choosen node handling and lets us remove some duplicated code when we fixup the initrd info in bootm on PPC. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| * fdt_support: fdt_fixup_dr_usb: add support for phy_type fixupsAnton Vorontsov2008-07-16-7/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently U-Boot can only fixup the usb dr_mode, but some boards (namely MPC8315E-RDB) can use two PHY types: ULPI (stand-alone OTG port) or UTMI (connected to the four-ports hub, usb host only). This patch implements support for passing Dual-Role USB controller's device tree property phy_type through the usb_phy_type environment variable.

* | fdt: rework fdt_fixup_ethernet() to use env instead of bd_tKumar Gala2008-08-21-41/+27
|/ | | | | | | | | | Move to using the environment variables 'ethaddr', 'eth1addr', etc.. instead of bd->bi_enetaddr, bi_enet1addr, etc. This makes the code a bit more flexible to the number of ethernet interfaces. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* fdt: add crypto node handling for MPC8{3, 5}xxE processorsKim Phillips2008-07-14-0/+87
| | | | | | | | Delete the crypto node if not on an E-processor. If on 8360 or 834x family, check rev and up-rev crypto node (to SEC rev. 2.4 property values) if on an 'EA' processor, e.g. MPC8349EA. Signed-off-by: Kim Phillips <kim.phillips@freescale.com>

| | | | | | | | 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>

* 83xx/fdt_support: let user specifiy FSL USB Dual-Role controller roleAnton Vorontsov2008-03-25-0/+25
| | | | | | | | | 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>
* Remove deprecated CONFIG_OF_HAS_UBOOT_ENV and CONFIG_OF_HAS_BD_TJerry Van Baren2008-03-26-193/+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>

* 85xx: add ability to upload QE firmwareTimur Tabi2008-01-09-0/+48
| | | | | | | | | | | 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.

* Fine grained per property /chosen updating.Gerald Van Baren2008-01-08-33/+40
| | | | | | | | | | 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>

| | | | | | 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.
* Moved fdt command support code to fdt_support.cGerald Van Baren2007-04-06-0/+323
...in preparation for improving the bootm command's handling of fdt blobs. Also cleaned up some coding sloppiness.
