* libfdt: Implement property iteration functionsDavid Gibson2011-07-14-36/+200
| | | | | | | | | | | | | | | | | | | | | | | | | | | For ages, we've been talking about adding functions to libfdt to allow iteration through properties. So, finally, here are some. I got bogged down on this for a long time because I didn't want to expose offsets directly to properties to the callers. But without that, attempting to make reasonable iteration functions just became horrible. So eventually, I settled on an interface which does now expose property offsets. fdt_first_property_offset() and fdt_next_property_offset() are used to step through the offsets of the properties starting from a particularly node offset. The details of the property at each offset can then be retrieved with either fdt_get_property_by_offset() or fdt_getprop_by_offset() which have interfaces similar to fdt_get_property() and fdt_getprop() respectively. No explicit testcases are included, but we do use the new functions to reimplement the existing fdt_get_property() function.

* Support ePAPR compliant phandle propertiesDavid Gibson2011-07-14-6/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the Linux kernel, libfdt and dtc, when using flattened device trees encode a node's phandle into a property named "linux,phandle". The ePAPR specification, however - aiming as it is to not be a Linux specific spec - requires that phandles be encoded in a property named simply "phandle". This patch adds support for this newer approach to dtc and libfdt. Specifically: - fdt_get_phandle() will now return the correct phandle if it is supplied in either of these properties - fdt_node_offset_by_phandle() will correctly find a node with the given phandle encoded in either property. - By default, when auto-generating phandles, dtc will encode it into both properties for maximum compatibility. A new -H option allows either only old-style or only new-style properties to be generated. - If phandle properties are explicitly supplied in the dts file, dtc will not auto-generate ones in the alternate format. - If both properties are supplied, dtc will check that they have the same value. - Some existing testcases are updated to use a mix of old and new-style phandles, partially testing the changes. - A new phandle_format test further tests the libfdt support, and the -H option.

* powerpc/85xx: remove SERDES4 soft-reset work-aroundTimur Tabi2011-07-11-22/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some P4080 rev1 errata work-arounds, notably erratum SERDES4, required a bank soft-reset after the bank was configured and enabled, even though enabling a bank causes it to reset. Because the reset was required for multiple errata, it was not properly enclosed in an #ifdef, and so was not removed with all the other rev1 errata work-arounds. Erratum SERDES-8 says that the clocks for bank 3 needs to be enabled if bank 2 is enabled, but this was not being done for SERDES protocols 0xF and 0x10. The bank reset also happened to enable bank 3 (apparently an undocumented feature). Simply removing the reset breaks these two protocols. It turns out that every time we call enable_bank(), we do want at least one lane of the bank enabled, either because the bank is supposed to be enabled, or because we need the clock from that bank enabled. For erratum SERDES-A001, we don't want to modify srds_lpd_b[] when we call enable_bank(), because that array is used elsewhere to determine if the bank is available. Note that the side effect of these changes is that the work-arounds for these two errata are now linked. Specifically, if SERDES-A001 is enabled, then we need SERDES-8 enabled as well. Because this was the only SERDES bank soft-reset, there is no need to implement a work-around for erratum SERDES-A003. Also fix an off-by-one error in a printf().
