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.

2014-08-22ARM: Overhaul the ARM Makefile.Gabe Black
The ARM Makefile was copied from x86 and then modified, and as a result it was carrying a lot of baggage. On top of that, the extra complication made it inflexible, and we need a lot of flexiblity in order to support the fact that the Tegra124 starts on an ARMv4 coprocessor instead of one of the ARMv7 main CPUs.

2013-12-21exynos5250: Implement support to boot with USB A-A firmware uploadJulius Werner
This patch implements the basic infrastructure required to use the USB A-A firmware upload feature on Exynos5 processors with Coreboot. It will require a corresponding host-side script that activates the feature and uploads the correct image parts in the correct order to harcoded target addresses, as described in the comments of alternate_cbfs.c. Also fixes a bug in the Google Snow mainboard where it would not correctly initialize the pinmux configuration for the SPI flash bus. During a normal SPI boot the IROM would already do that for you, but when booting from USB you have to do it yourself.

Add a microsecond timer, its declaration, the function to start it, and its usage. To start it, one calls timer_start(). From that point on, one can call timer_us() to find microseconds since the timer was started. We show its use in the bootblock. You want it started very early. Finally, the delay.h change having been (ironically) delayed, we create time.h and have it hold one declaration, for the timer_us() and timer_start() prototype. We feel that these two functions should become the hardware specific functions, allowing us to finally move udelay() into src/lib where it belongs.

2013-03-19armv7/exynos/snow: new cache maintenance APIDavid Hendricks
This adds a new API for cache maintenance operations. The idea is to be more explicit about operations that are going on so it's easier to manage branch predictor, cache, and TLB cleans and invalidations. Also, this adds some operations that were missing but required early on, such as branch predictor invalidation. Instruction and sync barriers were wrong earlier as well since the imported API assumed we compield with -march=armv5 (which we don't) and was missing wrappers for the native ARMv7 ISB/DSB/DMB instructions. For now, this is a start and it gives us something we can easily use in libpayload for doing things like cleaning and invalidating dcache when doing DMA transfers. TODO: - Set cache policy explicitly before re-enabling. Right now it's left at default. - Finish deprecating old cache maintenance API. - We do an extra icache/dcache flush when going from bootblock to romstage.

2013-02-20ARMV7: minor tweaks to inter-stage calling and payload handling.Ronald G. Minnich
Payloads, by design, can return. There's lots of mechanism in the payload code to support it, and the chooser payload relies on it. Hence, we should not mark the function call in exit_stage as noreturn. Not all ARM have unified caches, and it's not always easy to tell what to do. So we are very paranoid. Before we call between stages, we should carefully flush the dcache to memory and invalidate the icache. This may be more than is necessary on all architectures but it doesn't really hurt for the most part. So compile cache management code into all stages, and call the flush dcache/invalidate icache from all stages. Change-Id: Ib9cc625c4dfd2d7d4b3c69a74686cc655a9d6484 Signed-off-by: Ronald G.

Remove a function that is overly flexible, and even though it is overly flexible only actually can handle one type of RAM. Mainboards only support one type of DRAM, so create a function to explicitly initialize the type of DDR we have -- DDR3. With these changes, and the previous changes, google snow is ready to run the ramstage. Change-Id: I37e0ab0d2dbc1dd121fb175386a46bc2fb1285e5 Signed-off-by: Ronald G.

2013-01-03snow: Stuff to support building image with BL1David Hendricks
This patch does two things which will take effect in follow-up patches: 1. Add an intermediate Makefile rule for dd'ing BL1 into the coreboot.rom pre-image. This is modeled after a similar hack for the bd82x6x southbridge. 2. Add a Kconfig variable, BOOTBLOCK_OFFSET, which will be used to pass the bootblock offset into cbfstool.

2012-12-08WIP: Initial support for Samsung Exynos 5250 ARM CPUStefan Reinauer
Samsung SoC files, including Exynos5 (a Cortex-A15 implementation). Since this is an SoC we'll forego the x86-style {north,south}bridge and cpu distinction. We may try to split some stuff out before the final version if prudent.
