To move 3rdparty to 3rdparty/blobs (ie. below itself from git's broken perspective), we need to work around it - since some git implementations don't like the direct approach.

2014-08-26armv7: Move Exynos from 'cpu' to 'soc'.Hung-Te Lin
The Exynos family and most ARM products are SoC, not just CPU. We used to put ARM code in src/cpu to avoid polluting the code base for what was essentially an experiment at the time. Now that it's past the experimental phase and we're going to see more SoCs (including intel/baytrail) in coreboot.

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).

2014-05-06Introduce stage-specific architecture for corebootFurquan Shaikh
Make all three coreboot stages (bootblock, romstage and ramstage) aware of the architecture specific to that stage i.e. we will have CONFIG_ARCH variables for each of the three stages. This allows us to have an SOC with any combination of architectures and thus every stage can be made to run on a completely different architecture independent of others. Thus, bootblock can have an x86 arch whereas romstage and ramstage can have arm32 and arm64 arch respectively. These stage specific CONFIG_ARCH_ variables enable us to select the proper set of toolchain and compiler flags for every stage. These options can be considered as either arch or modes eg: x86 running in different modes or ARM having different arch types (v4, v7, v8). We have got rid of the original CONFIG_ARCH option completely as every stage can have any architecture of its own. Thus, almost all the components of coreboot are identified as being part of one of the three stages (bootblock, romstage or ramstage). The components which cannot be classified as such e.g. smm, rmodules can have their own compiler toolset which is for now set to *_i386. Hence, all special classes are treated in a similar way and the compiler toolset is defined using create_class_compiler defined in Makefile. In order to meet these requirements, changes have been made to CC, LD, OBJCOPY and family to add CC_bootblock, CC_romstage, CC_ramstage and similarly others. Additionally, CC_x86_32 and CC_armv7 handle all the special classes. All the toolsets are defined using create_class_compiler. Few additional macros have been introduced to identify the class to be used at various points, e.g.: CC_$(class) derives the $(class) part from the name of the stage being compiled. We have also got rid of COREBOOT_COMPILER, COREBOOT_ASSEMBLER and COREBOOT_LINKER as they do not make any sense for coreboot as a whole. All these attributes are associated with each of the stages.

2013-07-10i2c: Change the type of the data parameter to uint8_t.Gabe Black
Data is intended to be a byte array, so it should be described by a type which has a fixed size equal to an 8 bit byte. Also, the data passed to write shouldn't be modified and can be const.
