2015-03-17rmodules: Make rmodules inclusion for vboot dependent on romstage_archFurquan Shaikh
Currently, the rmodules inclusion for vboot is dependent on ramstage_arch. This change adds dependency on romstage_arch, since vboot is associated with romstage. Inclusion based on ramstage_arch is left as is in case someone needs it in ramstage.

2015-03-17coreboot classes: Add dynamic classes to corebootFurquan Shaikh
Provide functionality to create dynamic classes based on program name and the architecture for which the program needs to be compiled/linked. define_class takes program_name and arch as its arguments and adds the program_name to classes-y to create dynamic class and compiler toolset is created for the specified arch. All the files for this program can then be added to program_name-y += .. Ensure that define_class is called before any files are added to the class. Check subdirs-y for order of directory inclusion. One such example of dynamic class is rmodules. Multiple rmodules can be used which need to be compiled for different architectures. With dynamic classes, this is possible.

Ramstage needs an assembly entry point for setting up the initial state of the CPU.

Currently the entry point after initialization is 'main', however it can be changed/extended to do more work such as seeding the stack contents with tombstones, etc. It should be noted that romstage and bootblock weren't tested.

Because we had no stack on romcc boards, we had a separate, not as powerful clone of printk: print_*. Back in the day, like more than half a decade ago, we migrated a lot of boards to printk, but we never cleaned up the existing code to be consistent. Instead, we worked around the problem with a very messy console.h (nowadays the mess is hidden in romstage_console.c and early_print.h) This patch cleans up the generic code pieces to use printk() on all non-ROMCC boards. Our two remaining ROMCC boards are fixed up in this commit: bifferos/bifferboard and dmp/vortex86ex.

2015-01-03arm: Fix stored PC value when handling exceptionsJulius Werner
ARM processors save the PC value in the Link Register when they handle and exception, but they store it with an added offset (depending on the exception type). In order to make crashes easier to read and correctly support more complicated handlers in libpayload, this patch adjusts the saved PC value on exception entry to correct for that offset. (Note: The value that we now store is what ARM calls the "preferred return address". For most exceptions this is the faulting instruction, but for software interrupts (SWI) it is the instruction after that. This is the way most programs like GDB expect the stored PC address to work, so let's leave it at that.) Numbers taken from the Architecture Reference Manual at the end of section B1.8.3. BRANCH=none BUG=chrome-os-partner:18390 TEST=Provoked a data abort and an undefined instruction in both coreboot and depthcharge, confirmed that the PC address was spot on.

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.

2014-12-09libpayload: arm: Pass the coreboot table location to the payload.Gabe Black
To find the coreboot tables, the payload has historically searched for their signature in a predefined region of memory. This is a little clumsy on x86, but it works because you can assume certain regions are RAM. Also, there are areas which are set aside for the firmware by convention. On x86 there's a forwarding entry which goes in one of those fairly small conventional areas and which points to the CBMEM area at the end of memory. On ARM there aren't areas like that, so we've left out the forwarding entry and gone directly to CBMEM. RAM may not start at the beginning of the address space or go to its end, and that means there isn't really anywhere fixed you can put the coreboot tables. That's meant that libpayload has to be configured on a per board basis to know where to look for CBMEM. Now that we have boards that don't have fixed amounts of memory, the location of the end of RAM isn't fixed even on a per board level which means even that workaround will no longer cut it. This change makes coreboot pass the location of the coreboot tables to libpayload using r0, the first argument register. That means we'll be able to find them no matter where CBMEM is, and we can get rid of the per board search ranges. We can extend this mechanism to x86 as well, but there may be more complications and it's less necessary there. It would be a good thing to do eventually though. BUG=None TEST=Built and booted on nyan. Changed the size of memory and saw that the payload could still find the coreboot tables where before it couldn't. Built for pit, snow, and big.

2014-11-13arm: Put assembly functions into separate sectionsJulius Werner
This patch changes the ENTRY() macro in asm.h to create a new section for every assembler function, thus providing dcache_clean/invalidate_all and friends with the same --gc-sections goodness that our C functions have. This requires a few minor changes of moving around data (to make sure it ends up in the right section) and changing some libgcc functions (which apparently need to have two names?), but nothing serious. (You may note that some of our assembly functions have data, sometimes even writable, within the same .text section. This has been this way before and I'm not looking to change it for now, although it's not totally clean. Since we don't enforce read-only sections through paging, it doesn't really hurt.) BUG=None TEST=Nyan and Snow still boot. Confirm dcache_invalidate_all is not output into any binary anymore since no one actually uses it.

2014-11-10arm: Redesign, clarify and clean up cache related codeJulius Werner
This patch changes several cache-related pieces to be cleaner, faster or more correct. The largest point is removing the old arm_invalidate_caches() function and surrounding bootblock code to initialize SCTLR and replace it with an all-assembly function that takes care of cache and SCTLR initialization to bring the system to a known state. It runs without stack and before coreboot makes any write accesses to be as compatible as possible with whatever state the system was left in by preceeding code. This also finally fixes the dreaded icache bug that wasted hundreds of milliseconds during boot.

2014-11-09arm: Thumb ALL the things!Julius Werner
This patch switches every last part of Coreboot on ARM over to Thumb mode: libpayload, the internal libgcc, and assorted assembly files. In combination with the respective depthcharge patch, this will switch to Thumb mode right after the entry point of the bootblock and not switch back to ARM until the final assembly stub that jumps to the kernel. The required changes to make this work include some new headers and Makefile flags to handle assembly files (using the unified syntax and the same helper macros as Linux), modifying our custom-written libgcc code for 64-bit division to support Thumb (removing some stale old files that were never really used for clarity), and flipping the general CFLAGS to Thumb (some more cleanup there as well while I'm at it).

2014-11-05ARM: Use local versions of libgcc functions instead of linking against libgcc.Gabe Black
The flags used to compile libgcc may make it incompatible with the code it's linked against, and/or the hardware it's going to run on. Rather than try to tease the right libgcc from the compiler, lets just leave it out and use our own implementations of the necessary functions. Most of these implementations were taken from the Linux kernel, except for uldivmod.S which was taken from a CL originally written for U-Boot by Che-Liang Chiou in December of 2010. It was modified to not use the CLZ instruction on machines that don't have it, anything earlier than ARMv5. The top block was taken from an earlier version of the same CL which didn't use CLZ in that spot. The later block was written from scratch. BUG=None TEST=Built and booted into the bootblock on nyan. Ran a series of tests which divided and modded a 64 bit value by various 32 bit values which were powers of 2. Confirmed that this function was used and that the returned value was correct. Printed decimal and hex versions of some values and verified that they equaled each other. Built and booted on pit with serial enabled.
