2014-09-25pit: Rename pit to peach_pit.Gabe Black
The name pit goes by in many places in chromeos is peach_pit, where peach is the base name and pit is the name of this particular variant. To make it easier to work with within chromeos and to make the board names a little less ambiguous, this change renames the pit board to peach_pit, and from Pit to Peach Pit.

2014-09-13arm: Move exception_init() close to console_init()Julius Werner
This patch adds stub implementations of exception_init() to all archs so that it can be called from src/lib/hardwaremain.c. It also moves/adds all other invocations of exception_init() (which needs to be rerun in every stage) close to console_init(), in the hopes that it will be less likely overlooked when creating future boards. Also added (an ineffective) one to the armv4 bootblock implementations for consistency and in case we want to implement it later.

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.

2014-08-14exynos5: 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).

2014-08-13arm: 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.

2014-08-12exynos5420: Make USB A-A booting work with early data cacheJulius Werner
Apparently the IROM doesn't like data caches... the recently added dcache-in-bootblock makes A-A booting fail, and flushes/invalidations alone don't seem to fix it. It's pretty fast anyway, so we just disable the cache again for the duration of the IROM call. Also removes a superfluous invalidation line from the bootblock code... dcache_mmu_enable/disable already take care of that.

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.

2013-12-21pit: Add missing elements to the edid data structureGabe Black
When the edid data structure changed a while ago, it caused hangs on snow which were fixed by adding those missing members. Unfortunately we didn't realize that pit needed the same fix.

2013-07-10pit: Redo the display port bridge initialization code.Gabe Black
The display port bridge on pit is different from the one on snow and needs to be initialized differently. Instead of waiting for the chip to come up on its own and assert the hotplug detect, we need to access it over i2c and get it up and running ourselves.

2013-07-10pit: Replace the tps65090 functions and adjust the hotplug detect line.Gabe Black
The functions which manipulated the tps65090 were removed a while ago because it isn't accessible directly from the AP, it's on an I2C bus that has to be accessed by the EC on our behalf. Now that that capability has been added, we can rewrite the small portion of the the tps65090 we actually used but using the EC passthrough commands. Also, we should not be configuring the hardware display port hotplug detect line since we're using it as a GPIO for other purposes. The GPIO we're using instead defaults to being an input, but to be safe we should probably explicitly configure it as one anyway.

It was also passing around a structure which was used to calculate a single value which was already known when that structure was put together. Eliminate the extra space, and pass the single value instead of the structure.
