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.

2014-08-13arm: libpayload: Add cache coherent DMA memory definition and managementJulius Werner
This patch adds a mechanism to set aside a region of cache-coherent (i.e. usually uncached) virtual memory, which can be used to communicate with DMA devices without automatic cache snooping (common on ARM) without the need of explicit flush/invalidation instructions in the driver code. This works by setting aside said region in the (board-specific) page table setup, as exemplary done in this patch for the Snow and Pit boards. It uses a new mechanism for adding board-specific Coreboot table entries to describe this region in an entry with the LB_DMA tag. Libpayload's memory allocator is enhanced to be able to operate on distinct types/regions of memory. It provides dma_malloc() and dma_memalign() functions for use in drivers, which by default just operate on the same heap as their traditional counterparts. However, if the Coreboot table parsing code finds a CB_DMA section, further requests through the dma_xxx() functions will return memory from the region described therein instead.

2014-08-11coreboot classes: Add dynamic classes to corebootFurquan Shaikh
Provide functionality to create dynamic classes based on program name and architecture for which the program needs to be compiled/linked. define_class takes program_name and arch as its arguments and adds the program_name to classes-y to create dynamic class. Also, compiler toolset is created for the specified arch. All the files for this program can then be added to program_name-y += .. Ensure that define_class is called before any files are added to the class. Check subdirs-y for order of directory inclusion. One such example of dynamic class is rmodules. Multiple rmodules can be used which need to be compiled for different architectures. With dynamic classes, this is possible.

2014-08-10cbfs: Check return value of map() for errorJulius Werner
The CBFS core checks the result of a media->map() operation in multiple places for CBFS_MEDIA_INVALID_MAP_ADDRESS, suggesting that this is a valid response. However, it ironically fails to do so when actually mapping the CBFS file itself, which can fail on buffer-constrained systems since the size is much larger than when mapping metadata. This patch adds a check with an error message and a NULL pointer return for that case to make it easier to understand this condition.

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.

Follow-up patches will re-enable all the consoles removed here, in a more flexible fashion, and with less lines-of-code and copy-paste.

Since the header is not compiled and linked together with an rmodule there needs to be a way of marking which symbol is the entry point. __rmodule_entry is the symbol used for knowing the entry point. There was a little churn in SMM modules to ensure an rmodule entry point symbol takes a single argument.

CACHE_ROM requires the user to sanity check their boot output because the feature is brittle. The working configuration is dependent on I/O hole size, ram size, and chipset.

This includes the new dp code, which is better, and the fimd code, which is changed and improved. We took the chance to remove un-needed files, and also to remove some foolish u-boot habits, but not all of them. That will take time. With these changes we get graphics. Since the only mainboards we have with 16 bit graphics are 5:6:5, adjust edid.c to just use that format. If at some future time we need 4:4:4, which seems unlikely, we'll need to add a function to adjust the lb_framebuffer. Note that you can't just divine this from the EDID, as the graphics pipe format need not match the actual final format used. The EDID reading works. We've been requested to support hard-coded EDIDs and that will come in the next revision. Currently the hard-coded EDID is ignored for testing.
