2015-02-23cpu/amd/agesa: Use alloc_cbmem() only in ramstageDave Frodin
This copies a change made in commit 1cc3338 that allows alloc_cbmem() to be called only in ramstage. This will allow the */cpu/amd/agesa/* field to be removed from the list of illegal_globals EXCLUDE_FILEs. TEST: Booted the amd/parmer board.

2015-02-21cpu/amd/pi: Use alloc_cbmem() only in ramstageDave Frodin
Without this change the builder would fail with the complaint that there was a global static variable in romstage. alloc_cbmem() is only called in ramstage. The alternative was to add */cpu/amd/pi/*.romstage.o to the list of illegal_globals EXCLUDE_FILEs in arch/x86/init/romstage.ld. TEST: Booted the amd/lamar board.

The default linking behavior of ramstage was changed in commit * 8f99378 ARMv7/Exynos: Fix memory location assumptions However, that commit failed to address the issue of maintaining linking behavior on non-Exynos chips. As a result we ended up linking ramstage at address 0, which is outside of SDRAM. Explicitly link ramstage at SDRAM base for A10. This patch does not address the issue on other chips that were broken by commit 8f99378.

2015-02-06FSP & CBMEM: Fix broken cbmem CAR transition.Martin Roth
1) Save the pointer to the FSP HOB list to low memory at address 0x614. This is the same location as CBMEM_RESUME_BACKUP - the two aren't used in the same platform, so overlapping should be OK. I didn't see any documentation that actually said that this location was free to use, and didn't need to be restored after use in S3 resume, but it looks like the DOS boot vector gets loaded juat above this location, so it SHOULD be ok. The alternative is to copy the memory out and store it in cbmem until we're ready to restore it. 2) When a request for the pointer to a CAR variable comes in, pass back the location inside the FSP hob structure. 3) Skip the memcopy of the CAR Data. The CAR variables do not get transitioned back into cbmem, but used out of the HOB structure. 4) Remove the BROKEN_CAR_MIGRATE Kconfig option from the FSP platform.

It's a stage in the sense that it has its own set of toolchains, compiler flags, and includes. This allows us to easily add object files as needed. But it's directly linked to bootblock. This allows us to avoid code duplication for stage loading and jumping (e.g. cbfs driver) for the boards where bootblock has to run in a different architecture (e.g. Tegra124). To avoid name space conflict, verstage symbols are prefixed with verstage_. TEST=Built with VBOOT2_VERIFY_FIRMWARE on/off. Booted Nyan Blaze.

2014-12-30i2c: Add software_i2c driver for I2C debugging and emulationJulius Werner
This patch adds I2C emulation in software through raw toggling of the SDA/SCL lines. Platforms need to provide bindings to toggle their respective I2C busses for this to work (e.g. by pinmuxing them as GPIOs, currently only enabled for Tegra). This is mostly useful as a debugging feature, to drive unusual states on a bus and closely monitor the device output without the need of a bus analyzer. It provides a few functions to "wedge" an I2C bus by aborting a transaction at certain points, which can be used to test if a system can correctly recover from an ill-timed reboot. However, it can also dynamically replace the existing I2C transfer functions and drive some/all I2C transfers on the system, which might be useful if a driver for the actual I2C controller hardware is not (yet) available. Based on original code by Doug Anderson <dianders@chromium.org> and Hung-ying Tyan <tyanh@chromium.org> for the ChromeOS embedded controller project. BRANCH=None BUG=chrome-os-partner:28323 TEST=Spread tegra_software_i2c_init()/tegra_software_i2c_disable() through the code and see that everything still works.

2014-12-30ipq/arm: Redesign hooks for bootblockVadim Bendebury
The following patches had to be squashed to properly build all the different ARM boards. ipq8064: storm: re-arrange bootblock initialization The recent addition of the storm bootblock initialization broke compilation of Exynos platforms. The SOC specific code needs to be kept in the respective source files, not in the common CPU code. As of now coreboot does not provide a separate SOC initialization API. In general it makes sense to invoke SOC initialization from the board initialization code, as the board knows what SOC it is running on. Presently all what's need initialization on 8064 is the timer. This patch adds the SOC initialization framework for 8064 and moves there the related code. BUG=chrome-os-partner:27784 TEST=manual . nyan_big, peach_pit, and storm targets build fine now.

Experience has shown that nearly every board needs either one or both of these hooks, so having explicit Kconfigs for them has become unwieldy. Instead, this patch implements them as a weak symbol that can be overridden by mainboard/SoC code, as the more recent arm64_soc_init() is also doing. Since the whole concept of a single "CPU" on ARM systems has kinda died out, rename bootblock_cpu_init() to bootblock_soc_init(). (This had already been done on Storm/ipq806x, which is now adjusted to directly use the generic hook.) Also add a proper license header to bootblock_common.h that was somehow missing. Leaving non-ARM32 architectures out for now, since they are still using the really old and weird x86 model of directly including a file. These architectures should also eventually be aligned with the cleaner ARM32 model as they mature. BRANCH=None BUG=chrome-os-partner:32123 TEST=Booted on Pinky. Compiled for Storm and confirmed in the disassembly that bootblock_soc_init() is still compiled in and called right before the (now no-op) bootblock_mainboard_init().

When using fixed MTRRs for CAR setup, CONFIG_DCACHE_RAM_BASE is ignored and was not correctly set on affected sockets and boards. It was still referenced in romstage linker script. This was discovered by clang builds failing for cases where DCACHE_RAM_BASE = 0, while gcc builds passed. The actual DCACHE_RAM_BASE programming is base = 0xd0000 - size, as taken from intel/cpu/cache_as_ram.inc.
