Go one step further and also remove the srand() call. There's no reason we want non-deterministic behaviour from this script.

When ordering SROM layout entries, we now use the unique (var_id, rev_start, rev_end) tuple as the sort key; this fixes the previously non-deterministic output when sorting entries with overlapping var_ids.

* bhnd(4): NVRAM serialization support.Landon J. Fuller2016-12-191-7/+29
| | | | | | | | | | | | | | | | This adds support for: - Serializing an bhnd_nvram_plist (as exported from bhnd_nvram_store, etc) to an arbitrary NVRAM data format. - Generating a serialized representation of the current NVRAM store's state suitable for writing back to flash, or re-encoding for upload to a FullMAC device.

* bhnd(4): Unify NVRAM/SPROM parsing, implement compact SPROM layout encoding.Landon J. Fuller2016-11-261-765/+3803
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Defined an abstract NVRAM I/O API (bhnd_nvram_io), decoupling NVRAM/SPROM parsing from the actual underlying NVRAM data provider (e.g. CFE firmware devices). - Defined an abstract NVRAM data API (bhnd_nvram_data), decoupling higher-level NVRAM operations (indexed lookup, data conversion, etc) from the underlying NVRAM file format parsing/serialization. - Implemented a new high-level bhnd_nvram_store API, providing indexed variable lookup, pending write tracking, etc on top of an arbitrary bhnd_nvram_data instance. - Migrated all bhnd(4) NVRAM device drivers to the common bhnd_nvram_store API. - Implemented a common bhnd_nvram_val API for parsing/encoding NVRAM variable values, including applying format-specific behavior when converting to/from the NVRAM string representations. - Dropped the now unnecessary bhnd_nvram driver, and moved the broadcom/mips-specific CFE NVRAM driver out into sys/mips/broadcom. - Implemented a new nvram_map file format: - Variable definitions are now defined separately from the SPROM layout. This will also allow us to define CIS tuple NVRAM mappings referencing the common NVRAM variable definitions. - Variables can now be defined within arbitrary named groups. - Textual descriptions and help information can be defined inline for both variables and variable groups. - Implemented a new, compact encoding of SPROM image layout offsets. - Source-level (but not build system) support for building the NVRAM file format APIs (bhnd_nvram_io, bhnd_nvram_data, bhnd_nvram_store) as a userspace library. The new compact SPROM image layout encoding is loosely modeled on Apple dyld compressed LINKEDIT symbol binding opcodes; it provides a compact state-machine encoding of the mapping between NVRAM variables and the SPROM image offset, mask, and shift instructions necessary to decode or encode the SPROM variable data. The compact encoding reduces the size of the generated SPROM layout data from roughly 60KB to 3KB. The sequential nature SPROM layout opcode tables also simplify iteration of the SPROM variables, as it's no longer neccessary to iterate the full NVRAM variable definition table, but instead simply scan the SPROM revision's layout opcode table.

* bhnd(4): Implement NVRAM support required for PMU bring-up.Landon J. Fuller2016-08-161-19/+19
| | | | | | | | | | | | | | | | | | | | | | | | | - Added a generic bhnd_nvram_parser API, with support for the TLV format used on WGT634U devices, the standard BCM NVRAM format used on most modern devices, and the "board text file" format used on some hardware to supply external NVRAM data at runtime (e.g. via an EFI variable). - Extended the bhnd_bus_if and bhnd_nvram_if interfaces to support both string-based and primitive data type variable access, required for common behavior across both SPROM and NVRAM data sources. - Extended the existing SPROM implementation to support the new string-based NVRAM APIs. - Added an abstract bhnd_nvram driver, implementing the bhnd_nvram_if atop the bhnd_nvram_parser API. - Added a CFE-based bhnd_nvram driver to provide read-only access to NVRAM data on MIPS SoCs, pending implementation of a flash-aware bhnd_nvram driver.

| | | | | | | | | | | | | | | | | | | This adds bhnd-compatible implementations of bus_(read|write|set)_(1|2|4) APIs, and upgrades the SPROM parsing code to use bhnd_bus_read_region_stream_2().

* [bhnd] Initial bhnd(4) SPROM/NVRAM support.Adrian Chadd2016-05-083-0/+1174
| | | | | | | | | | | | | | | | | | | | | | This adds support for the NVRAM handling and the basic SPROM hardware used on siba(4) and bcma(4) devices, including: * SPROM directly attached to the PCI core, accessible via PCI configuration space. * SPROM attached to later ChipCommon cores. * SPROM variables vended from the parent SoC bus (e.g. via a directly-attached flash device). Additional improvements to the NVRAM/SPROM interface will be required, but this changeset stands alone as working checkpoint.

* Bring over the initial rewrite of the broadcom bus support found in theirAdrian Chadd2016-02-261-0/+84
SoCs and various chips (including, famously, their wifi chips.) This is "just" (all 20,000 lines of it) code to enumerate the various versions of busses inside these devices, including the PCI bridge and the direct SIBA bridge found in MIPS chips. It also includes shared code for some bus operations (suspend, resume, etc); EEPROM/SROM/etc parsing and other things that are shared between chips. Eventually this'll replace the code that bwi/bwn uses for the internal bus, as well as some apparently upcoming mips74k broadcom SoC support which uses bwn!
