2015-11-21hexdump: Fix output if length is not a multiple of 16Ben Gardner
hexdump currently rounds up length to a multiple of 16. So, hexdump(ptr, 12) prints 16 hex digits, including 4 garbage bytes. That isn't desirable and is easy to fix.

2015-11-19vendorcode/google/chromeos: Cache VPD data into CBMEMHung-Te Lin
There are few drawbacks reading VPD from SPI flash in user land, including "lack of firmware level authority" and "slow reading speed". Since for many platforms we are already reading VPD in firmware (for example MAC and serial number), caching the VPD data in CBMEM should will speed up and simplify user land VPD processing without adding performance cost. A new CBMEM ID is added: CBMEM_ID_VPD, referring to a structure containing raw Google VPD 2.0 structure and can be found by the new LB_TAG_VPD in Coreboot tables.

2015-11-19edid: Don't half parse (and wrongly print) more detailed timingsDouglas Anderson
The EDID parsing code continued to update _some_ fields of the output edid but not others if "did_detailed_timing" was already set. It also then went on to print out this halfway mix of modes each time, despite the fact that it didn't really update everything. Let's fix that. We'll reduce code changes by using a temporary copy of data in detailed_block() and then we'll copy it back if we decide we should update.

2015-11-19edid: Use a better mode for 640x480Douglas Anderson
The hardcoded clock value for 640x480 was 25.175 MHz. That's a valid clock to use, but is quite hard to make a non-jittery clock from PLLs. It's much easier to make 25.200 MHz, so let's do that. The difference between the two modes is 59.9 Hz vs. 60 Hz and it seems better to make a non-jittery 60 Hz rather than a very jittery 59.9 Hz.

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.

Per IRC and Gerrit discussion, the normal / fallback selector code is a rather weak spot in coreboot, and did not function correctly for certain use cases. Rework the selector to more clearly indicate proper operation, and also remove dead code. 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. BUG=None BRANCH=None TEST=Built emulation/qemu-armv7 and noted bootblock.bin contains the cleared bss.

Patch b2a62622b (linking: move romstage and bootblock to use program.ld) unified the linker scripts between different stages.

This patch expands program.ld to once again merge the .BSS into the program image for bootblocks (ensuring correct initialization by the external loader).

The reasoning is that Chrome OS doesn't always do display initialization during startup. It's runtime dependent.

Instead provide one function, display_init_required(), that provides the policy for determining display initialization action. For Chrome OS devices this function honors vboot_skip_display_init() and all other configurations default to initializing display.

All other non-x86 systems use the monotonic timer which has a 1us granularity or 1MHz. One of the main reasons is that Linux is reporting /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq as the true turbo frequency on turbo enables machines. This change also fixes the p-state values honored in cpufreq for turbo machines in that turbo p-pstates were reported as 100MHz greater than nominal.

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. BRANCH=veyron BUG=None TEST=Compiled Cosmos, Daisy, Falco, Blaze, Pit, Storm, Urara and Pinky, made sure they still build as well as before and don't show any stack usage warnings.
