* FSL DDR: Rewrite the FSL mpc8xxx DDR controller setup code.Kumar Gala2008-08-27-2/+2573
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The main purpose of this rewrite it to be able to share the same initialization code on all FSL PowerPC products that have DDR controllers. (83xx, 85xx, 86xx). The code is broken up into the following steps: GET_SPD COMPUTE_DIMM_PARMS COMPUTE_COMMON_PARMS GATHER_OPTS ASSIGN_ADDRESSES COMPUTE_REGS PROGRAM_REGS This allows us to share more code an easily allow for board specific code overrides. Additionally this code base adds support for >4G of DDR and provides a foundation for supporting interleaving on processors with more than one controller.

* bootm: refactor do_reset and os boot function argsKumar Gala2008-08-26-117/+62
| | | | | | | | | | | | There is no need for each OS specific function to call do_reset() we can just do it once in bootm. This means its feasible on an error for the OS boot function to return. Also, remove passing in cmd_tbl_t as its not needed by the OS boot functions. flag isn't currently used but might be in the future so we left it alone.

* bootm: refactor image detection and os load stepsKumar Gala2008-08-26-108/+136
| | | | | | | | | | | | | | Created a bootm_start() that handles the parsing and detection of all the images that will be used by the bootm command (OS, ramdisk, fdt). As part of this we now tract all the relevant image offsets in the bootm_headers_t struct. This will allow us to have all the needed state for future sub-commands and lets us reduce a bit of arch specific code on SPARC. Created a bootm_load_os() that deals with decompression and loading the OS image. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | PCI I/O space is currently mapped 1:1 at 0xFA000000. Linux requires PCI I/O space to start at 0 on the PCI bus.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Freescale ships MPC8315E-RDB boards either with TSEC1 and USB UTMI support, or without TSEC1 but with USB ULPI PHY support in addition. With this patch user can specify desired USB PHY. Also, it seems that we can't distinguish the two boards in software, so user have to set `mpc8315erdb' environment variable to either 'tsec1' (TSEC1 enabled) or `ulpi' (board with ULPI PHY, TSEC1 disabled), so that Linux will not probe for TSEC1.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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>

* | | libfdt: Implement fdt_get_property_namelen() and fdt_getprop_namelen()David Gibson2008-08-24-7/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As well as fdt_subnode_offset(), libfdt includes an fdt_subnode_offset_namelen() function that takes the subnode name to look up not as a NUL-terminated string, but as a string with an explicit length. This can be useful when the caller has the name as part of a longer string, such as a full path. However, we don't have corresponding 'namelen' versions for fdt_get_property() and fdt_getprop(). There are less obvious use cases for these variants on property names, but there are circumstances where they can be useful e.g. looking up property names which need to be parsed from a longer string buffer such as user input or a configuration file, or looking up an alias in a path with IEEE1275 style aliases. So, since it's very easy to implement such variants, this patch does so. The original NUL-terminated variants are, of course, implemented in terms of the namelen versions.

Except... I missed one. This patch applies the same treatment to _stringlist_contains(). While we're at it, also make it static since it's only used in the same file.

Often, it won't be practical to separate the embedded libfdt's namespace from that of the surrounding project. Which means there can be namespace conflicts between even libfdt's internal/static functions and functions or macros coming from the surrounding project's headers via libfdt_env.h. This patch, therefore, renames a bunch of libfdt internal functions and macros and makes a few other chances to reduce the chances of namespace collisions with embedding projects. Specifically: - Internal functions (even static ones) are now named _fdt_*() - The type and (static) global for the error table in fdt_strerror() gain an fdt_ prefix - The unused macro PALIGN is removed - The memeq and streq macros are removed and open-coded in the users (they were only used once each) - Other macros gain an FDT_ prefix - To save some of the bulk from the previous change, an FDT_TAGALIGN() macro is introduced, where FDT_TAGALIGN(x) == FDT_ALIGN(x, FDT_TAGSIZE) Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enabling -Wcast-qual warnings in dtc shows up a number of places where we are incorrectly discarding a const qualification. There are also some places where we are intentionally discarding the 'const', and we need an ugly cast through uintptr_t to suppress the warning. However, most of these are pretty well isolated with the *_w() functions. So in the interests of maximum safety with const qualifications, this patch enables the warnings and fixes the existing complaints.
