2014-11-20AMD: Isolate AGESA and PI build environmentsKyösti Mälkki
To backport features introduced with recent Chromebooks and/or Intel boards in general, heavy work on the AMD AGESA platform infrastructure is required. With the AGESA PI available in binary form only, community members have little means to verify, debug and develop for the said platforms. Thus it makes sense to fork the existing agesawrapper interfaces, to give AMD PI platforms a clean and independent sandbox. New directory layout reflects the separation already taken place under 3rdparty/ and vendorcode/.

2014-11-14AMD (K8/fam10): Rewrite CAR migration in post_cache_as_ramKyösti Mälkki
Old routine copied all of CAR region as-is right below CONFIG_RAMTOP. Most of this region was reserved to interleave AP CPU address spaces and unused on BSP CPU. The only part of CAR region requiring a copy in RAM is the sysinfo structure. Improved routine changes this as follows: A region of size 'backup_size' below CONFIG_RAMTOP is cleared. In case of S3 resume, OS context from this region is first copied to high memory (CBMEM_ID_RESUME). At stack switch, CAR stack is discarded. Top of the stack for BSP is located at 'CONFIG_RAMTOP - car_size' for the remaining part of the romstage. This region is part of 'backup_size' and was zeroed before the switch took place. Before CAR is torn down the region of CAR_GLOBALS (and CAR_CBMEM), including the relevant sysinfo data for AP nodes memory training, is copied at 'CONFIG_RAMTOP - car_size'. NOTE: While CAR_GLOBAL variables are recovered, there are currently no means to calculate their offsets in RAM. NOTE: Boards with multiple CPU packages are likely already broken since bbc880ee amdk8/amdfam10: Use CAR_GLOBAL for sysinfo This moved the copy of sysinfo in RAM from above the stack to below the stack, but code for AP CPU's was not adjusted accordingly.

2014-09-24x86: Minimize work done with the caches disabled in mtrr functions.Gabe Black
The code in src/cpu/x86/mtrr/mtrr.c disables caching in a few places when changing mtrr settings. While I can't find anything that says that's actually required, I can believe it's necessary. With that said, other code around the wrmsr instructions which actually modify the settings should be able to run with caching enabled with no ill effects. This is particularly true for two calls to printk, one in the fixed mtrr code and one in the variable, which could result in an arbitrary amount of work being done without caching. When changing the implementation of the cbmem console, these two printks caused a significant regression in boot performance on link of about 70ms which is about 10% of total firmware boot time. When the window where the cache is disabled is minimized, both this and the new implementation were about 30ms faster than the original boot time. For the variable MTRRs, we now store what we want to set the MSRs to and then write them all at once at the end of commit_var_mtrrs(). This way we don't have some set and some not, but we still minimize the time we spend with the caches disabled.

2014-09-15arm: Remove CAR_MIGRATE Kconfig and associated cruftJulius Werner
This is essentially a revert of commit 10bd772d. The CAR_MIGRATE mechanism is only useful to migrate variables from a special region (e.g. cache as RAM) into DRAM-backed CBMEM between different parts of the romstage (it does not persist into ramstage). Since ARM devices use SRAM for which there is no reason to become inaccessible in later parts of the romstage, this mechanism isn't useful for them. Removing it makes the romstage.ld script much simpler, which has the nice side-effect of putting the BSS at the end of the memory image (so that cbfstool can actually figure out that it doesn't need to be part of the ROM image).

2014-09-08ARM: Generalize armv7 as arm.Gabe Black
There are ARM systems which are essentially heterogeneous multicores where some cores implement a different ARM architecture version than other cores. A specific example is the tegra124 which boots on an ARMv4 coprocessor while most code, including most of the firmware, runs on the main ARMv7 core. To support SOCs like this, the plan is to generalize the ARM architecture so that all versions are available, and an SOC/CPU can then select what architecture variant should be used for each component of the firmware; bootblock, romstage, and ramstage.

2014-08-25intel/gma: Clarify code and use dedicated init for Google PeppyRonald G. Minnich
Peppy had some issues with FUI. We decided it was time to create peppy-specific gma.c and i915io.c files. Using yabel and the i915tool, we generated a replay attack, then interpolated against the slippy i915io.c to get something working. Also, in preparation for moving code out of the mainboard gma.c to generic driver code, we got rid of some hardcodes in the mainboard gma.c that have no business being there. The worst were the computation of gmch_[m,n] and it turns out that we had some long-standing bugs related to confusion about 'bpp'. I've killed the word bpp everywhere I could because there are at least 3 things that correspond to bpp. We now have framebuffer, pipe, and panel bpp. The names are long because I want to avoid all the mistakes we've all been making in the last year :-) Sadly, that means a lot of changes not just peppy-related, but they are simple and in a good cause. The test pattern generation is driven by a global variable in mainboard/peppy/gma.c. I've found in the past that it's very useful to have a function like this available, as one can activate it while using a jtag debugger: halt at the right place in ramstage, set the variable to 1, continue. It's not enough code to worry about always including. The last hard-codes for M and N registers are gone, and the function to set from generic intel_dp.c code works. To avoid screen trash on a dev mode boot, which we liked but nobody else did :-), we now take the time to put a pleasing background color that sort of doubles as a power LED. Rough timing is ramstage start is at 2.2, and dev setup is done at 3.3. These new platforms are depressingly slow to boot. Rom init alone is taking 1.9 seconds. 13 years ago it was 3 seconds from power on to bash prompt. These CPUs are at least 10x faster and take much longer to get going. Future work, once we get this through, is to move more functions to the intel driver, and combine the mainboard i915io.c into the mainboard gma.c. That separation only existed because i915io.c was generated by a tool, and it had lots of ugliness. Most ugliness is gone.

2014-08-18arm/exynos: Allow releasing UART retention for resume.Hung-Te Lin
The UART / serial console is put in retention state by kernel during suspend / resume path, which caused Coreboot not able to print any messages during resume. Sending values to the padret_uart_opt inside PMU may release UART, but that may also cause unexpected output when kernel is back. However, it's still very helpful when we are debugging suspend/resume inside Coreboot. To get UART message on resume, call wakeup_enable_uart() in boot block or romstage (before console_init).

2014-08-14exynos5: Refactor crazy old U-Boot base address macros awayJulius Werner
All this samsung_get_base_address_of_device_with_a_really_long_name() boilerplate makes my eyes bleed... I think there are so much cleaner ways to do this. Unfortunately changing this ends up touching nearly every Exynos5 file, but I hope you agree that it's worth it (and the sooner we get it over with, the better... I can't bring myself to make another device fit into that ugly scheme). This also removes the redundant EXYNOS5 base address definitions from the 5420 directory when there are EXYNOS5420 ones, to avoid complete confusion. The new scheme tries to use EXYNOS5 for base addresses and exynos5 for types that are common between the two processors, and EXYNOS5420/exynos5420 for things that have changes (although I probably didn't catch all differences).
