* fdt: call fdt_parent_offset fewer times while translating addressesScott Wood2010-08-19-37/+21
| | | | | | | | | | | | | | | fdt_parent_offset() is an expensive operation, so we'd like to reduce unnecessary calls to it. Further, the practice of iterating up to the root if address/size cells aren't found was apparently done for Linux for compatibility with certain buggy Open Firmware implementations, and U-Boot inherited the code. The compliant behavior is to treat a missing #address-cells as 2, and a missing #size-cells as 1 -- never looking anywhere but the immediate parent of the node of interest.

* fdt: Fix bug in size calculation in fdt_resize() with initrd useFeng Wang2010-08-09-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Original bug description from Feng (fdt_resize() bug caused "WARNING: could not set linux, initrd-start FDT_ERR_NOSPACE."): What I got is an error: "WARNING: could not set linux,initrd-start FDT_ERR_NOSPACE." after loading Device Tree blob. This in turn caused linux to miss init part. After some digging, I found out the reason for this error, it is caused by fdt_resize(). FDT blob got resized after filling in all board specific information of PowerPC. (in boot_body_linux()). It reduced blob size with only extra space for two fdt_reserve_entry, one for fdt itself, and one for initrd. Then it's aligned to a 0x1000 page boundary. However, later in fdt_initrd(), it could add two more properties, initrd-start AND initrd-end, each one needs at least two fdt_reserve_entry sizes done by _fdt_add_property() (name and value). Thus, the two fdt_reserve_entry extra space is not sufficient. So for some specific fdt size which is just under the page boundary after resizing, this will cause an error of FDT_ERR_NOSPACE in fdt_initrd() when setting those two properties, and failed to pass initrd information to linux. My fix is in fdt_resize(), leave at least 4 fdt_reserve_entry for initrd. So instead of 2*sizeof(struct fdt_reserve_entry) for actual_totalsize, use 5*sizeof(struc fdt_reserve_entry). Stefan: I got this same error on katmai, when trying to boot with initrd (run flash_self). This patch fixes this issue.

* fdt: Add function to alloc phandle valuesKumar Gala2010-07-26-0/+18
| | | | | | | | | | If we are creating reference (handles) to nodes in a device tree we need to first create a new phandle in node and this needs a new phandle value. So we search through the whole dtb to find the max phandle value and return the next greater value for a new phandle allocation.

| | | | | | | | | | | Given a compatible string and physical address try and find a node that matches. This is useful when we want to find a specific device node to update (for example if we have multiple PCI nodes we can use the physical address to distinguish them when trying to update the device tree).

* fdt: Add fdt_translate_address to convert reg node to cpu phys addrKumar Gala2010-07-20-0/+264
| | | | | | | | | | | | | This code is extracted out of the Linux Kernel code from arch/powerpc/kernel/prom_parse.c. We maintain some of the same structure to support multiple bus types even though we only have one in the current code. In the future we might want to translate across a PCI bus and thus it will be easier to add that functionality back in.

| | | | | | | | | | | | | | Add sec3.1 h/w geometry for fdt node fixups. Also, technically, whilst SEC v3.3 h/w honours the tls_ssl_stream descriptor type, it lacks the ARC4 algorithm execution unit required to be able to execute anything meaningful with it.

* fdt_resize(): fix actualsize calculations with unaligned blobsPeter Korsgaard2009-01-17-1/+1
| | | | | | | | | | | | | The code in fdt_resize() to extend the fdt size to end on a page boundary is wrong for fdt's not located at an address aligned on a page boundary. What's even worse, the code would make actualsize shrink rather than grow if (blob & 0xfff) was bigger than the amount of padding added by ALIGN(), causing fdt_add_mem_rsv to fail. Fix it by aligning end address (blob + size) to a page boundary instead. For aligned fdt's this is equivalent to what we had before. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

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