2016-02-26lib/bootblock: provide SoC callback parity with mainboardAaron Durbin
There was no 'early' call into the SoC code prior to console getting initialized. Not having this enforces the mainboard to drive the setup of the console which typically just ends up calling into the SoC code. Provide a SoC early init call to handle this without having to duplicate the same code in mainboards utilizing the same SoC.

2016-02-22cbfs: Add LZ4 in-place decompression support for pre-RAM stagesJulius Werner
This patch ports the LZ4 decompression code that debuted in libpayload last year to coreboot for use in CBFS stages (upgrading the base algorithm to LZ4's dev branch to access the new in-place decompression checks). This is especially useful for pre-RAM stages in constrained SRAM-based systems, which previously could not be compressed due to the size requirements of the LZMA scratchpad and bounce buffer. The LZ4 algorithm offers a very lean decompressor function and in-place decompression support to achieve roughly the same boot speed gains (trading compression ratio for decompression time) with nearly no memory overhead. For now we only activate it for the stages that had previously not been compressed at all on non-XIP (read: non-x86) boards. In the future we may also consider replacing LZMA completely for certain boards, since which algorithm wins out on boot speed depends on board-specific parameters (architecture, processor speed, SPI transfer rate, etc.). BRANCH=None BUG=None TEST=Built and booted Oak, Jerry, Nyan and Falco. Measured boot time on Oak to be about ~20ms faster (cutting load times for affected stages almost in half).

If the timestamp table gets corrupted (separate issue), the timestamp_sync_cache_to_cbmem() function may add a large number of bogus timestamp entries. This causes a flood of "ERROR: Timestamp table full". With logs going to a serial console, this renders the system essentially unbootable. There really isn't a need to log that more than once, so log it when the last slot in the timestamp table is filled.

2015-11-11arm/arm64: Generalize bootblock C entry pointJulius Werner
When we first added ARM support to coreboot, it was clear that the bootblock would need to do vastly different tasks than on x86, so we moved its main logic under arch/. Now that we have several more architectures, it turns out (as with so many things lately) that x86 is really the odd one out, and all the others are trying to do pretty much the same thing. This has already caused maintenance issues as the ARM32 bootblock developed and less-mature architectures were left behind with old cruft. This patch tries to address that problem by centralizing that logic under lib/ for use by all architectures/SoCs that don't explicitly opt-out (with the slightly adapted existing BOOTBLOCK_CUSTOM option). This works great out of the box for ARM32 and ARM64. It could probably be easily applied to MIPS and RISCV as well, but I don't have any of those boards to test so I'll mark them as BOOTBLOCK_CUSTOM for now and leave that for later cleanup.

Also tentatively abandon use of RTC bit 385; a follow-up patch will remove said bit from all affected mainboards. The correct operation of the fallback code selector approximates that of a power line recloser, with a user option to attempt normal boot that can be cleared by firmware, but never set by firmware. Additionally, if cleared by user, the fallback path should always be used on the next reboot.

2015-10-14x86: add standalone verstage supportAaron Durbin
To support x86 verstage one needs a working buffer for vboot. That buffer resides in the cache-as-ram region which persists across verstage and romstage. The current assumption is that verstage brings cache-as-ram up and romstage tears cache-as-ram down. The timestamp, cbmem console, and the vboot work buffer are persistent through in both romstage and verstage. The vboot work buffer as well as the cbmem console are permanently destroyed once cache-as-ram is torn down. The timestamp region is migrated. When verstage is enabled the assumption is that _start is the romstage entry point. It's currently expected that the chipset provides the entry point to romstage when verstage is employed. Also, the car_var_*() APIs use direct access when in verstage since its expected verstage does not tear down cache-as-ram. Lastly, supporting files were added to verstage-y such that an x86 verstage will build and link. BUG=chrome-os-partner:44827 BRANCH=None TEST=Built and booted glados using separate verstage.

2015-09-22linking: link bootblock.elf with .data and .bss sections againAaron Durbin
Currently coreboot expects the loader to clear the bss section for all stages. i.e. stages don't clear their own bss. On ARM SoCs the BootROM would be responsible for this. To do that one needs to include the bss section data (all zeros) in the bootblock.bin file. This was previously being attempted by keeping the .bss info in the .data section because objcopy happened zero out non-file allocated data section data. Instead go back to linking bootblock with the bss section but mark the bss section as loadable allocatable data. That way it will be included in the binary properly when objcopy -O binary is emplyed. Also do the same for the data section in the case of no non-zero object values are in the data section. Without this change the trick of including .bss in .data was not working when there wasn't a non-zero value object in the data section.

2015-07-29arm, arm64, mips: Add rough static stack size checks with -Wstack-usageJulius Werner
We've seen an increasing need to reduce stack sizes more and more for space reasons, and it's always guesswork because no one has a good idea how little is too litte. We now have boards with 3K and 2K stacks, and old pieces of common code often allocate large temporary buffers that would lead to very dangerous and hard to detect bugs when someone eventually tries to use them on one of those. This patch tries improve this situation at least a bit by declaring 2K as the minimum stack size all of coreboot code should work with. It checks all function frames with -Wstack-usage=1536 to make sure we don't allocate more than 1.5K in a single buffer. This is of course not a perfect test, but it should catch the most common situation of declaring a single, large buffer in some close-to-leaf function (with the assumption that 0.5K is hopefully enough for all the "normal" functions above that). Change one example where we were a bit overzealous and put a 1K buffer into BSS back to stack allocation, since it actually conforms to this new assumption and frees up another kilobyte of that highly sought-after verstage space. Not touching x86 with any of this since it's lack of __PRE_RAM__ BSS often requires it to allocate way more on the stack than would usually be considered sane.

2015-07-10timestamps: don't drop ramstage timestamps with EARLY_CBMEM_INITAaron Durbin
While running ramstage with the EARLY_CBMEM_INIT config the timestamp cache was re-initialized and subsequently used. The result was that the ramstage timestamps would be dropped from cbmem. The reason is that the ramstage timestamps perpetually lived in ramstage BSS never getting sync'd back into cbmem. The fix is to honor the cache state in ramstage in the timestamp_init() path. Also, make cache_state a fixed bit width to allow for different architectures across the pre-ramstage stages. TEST=Used qemu-armv7 as a test harness with debugging info.

2015-07-07timestamp: add generic cache regionAaron Durbin
In order to accommodate tracking timestamps in all the __PRE_RAM__ stages (bootblock, verstage, romstage, etc) of a platform one needs to provide a way to specify a persistent region of SRAM or cache-as-ram to store the timestamps until cbmem comes online.

2015-07-06lzma: Return correct amount of decompressed bytesJulius Werner
The LZMA functions are supposed to return the decompressed size, but what they actually return is just an unaltered field from the LZMA header that is *supposed* to contain the decompressed size. Apparently some encoders just overshoot that for no good reason. This patch changes the code such that the actual amount of decompressed bytes is returned.

2015-06-30hardwaremain: Move init_timer() call to before console initDuncan Laurie
The 8250 MMIO uart driver calls udelay, and if that is the first call then it will also call printk in init_timer() which can result in a deadlock trying to acquire the console lock. There are a few options to prevent this: 1) remove the printk in init_timer which removes a useful debug message 2) change the udelay() to cpu_relax() in uart8250mem.c 3- move the init_timer() call in ramstage main() to be called earlier Since hardwaremain.c:main() already has an explicit call to init_timer() on x86 it is an easy change to move this to happen before the console is initialized.
