ipq/arm: Redesign hooks for bootblock
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().

ARM: Generalize armv7 as arm.
There are ARM systems which are essentially heterogeneous multicores where some cores implement a different ARM architecture version than other cores. A specific example is the tegra124 which boots on an ARMv4 coprocessor while most code, including most of the firmware, runs on the main ARMv7 core. To support SOCs like this, the plan is to generalize the ARM architecture so that all versions are available, and an SOC/CPU can then select what architecture variant should be used for each component of the firmware; bootblock, romstage, and ramstage.

We don't always want to use ARMv7 code when building for ARM, so we should separate out the ARMv7 code so it can be excluded, and also make it possible to include code for some other version of the architecture instead, all per build component for cases where we need more than one architecture version at a time. The tegra124 bootblock will ultimately need to be ARMv4, but until we have some ARMv4 code to switch over to we can leave it set to ARMv7.
