2014-12-02Replace hlt with halt()Patrick Georgi
There were instances of unneeded arch/hlt.h includes, various hlt() calls that weren't supposed to exit (but might have) and various forms of endless loops around hlt() calls. All these are sorted out now: unnecessary includes are dropped, hlt() is uniformly replaced with halt() (except in assembly, obviously).

2014-09-22Add check_member macro to allow clean and easy struct offset checkingJulius Werner
This patch adds a new static assertion macro that can be used to check the offsets in structures that overlay register sets at compile time. It uses the _Static_assert() declaration from the new ISO C11 standard, which is supported (even without -std=c11) by GCC after version 4.6. (There is supposedly also support in clang, although I haven't tried it... let's deal with compiler issues when/if they turn up.) I've added it to all structures for our current ARM SoCs for now, and I think every new register overlay we add going forward should use them (at least for the last member, but feel free to add more if you think it's useful).

2014-09-15exynos5250: Fix PMU register address mapJulius Werner
Patch 12b121f3fef61d introduced an off-by-one error in the offsets of the PMU register struct, which put both the newly added register and the PSHOLD that comes after it in the wrong place. This patch corrects the offsets (5420 had already been correct).

2014-09-09exynos: Install the BL1 and set the checksum in the Makefile.Gabe Black
Install the BL1 and set up the checksum in the Makefile instead of relying on post processing. Import the exynos checksum script, split it in two and simplify it significantly. Stop putting the CBFS header in the midst of the bootblock so that it can be checksummed before CBFS is put together. Stop saving space for it and leaving an anchor in the bootblock which nobody looks for.

2014-08-29exynos: Fix the name of the chip_operations structures.Gabe Black
The exynos directories had been moved from src/cpu to src/soc, but the name of the chip_operations structure wasn't updated properly. That meant that the SOCs never installed their memory resources and the ram stage would fail to load the payload.

2014-08-29arm: libpayload: Make cache invalidation take pointers instead of integersJulius Werner
This minor refactoring patch changes the signature of all limited cache invalidation functions in coreboot and libpayload from unsigned long to void * for the address argument, since that's really what you have in 95% of the cases and I think it's ugly to have casting boilerplate all over the place.

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.
