2020-03-18soc: Remove copyright noticesPatrick Georgi
They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

2019-07-12arch, include, soc: Use common stdint.hJacob Garber
There are only minimal differences between the architecture specific stdint.h implementations, so let's tidy them up and merge them together into a single file. In particular, - Use 'unsigned long' for uintptr_t. This was already the case for x86 and riscv, while arm and mips used 'unsigned int', and arm64 and ppc64 used 'unsigned long long'. This change allows using a single integer type for uintptr_t across all architectures, and brings it into consistency with the rest of the code base, which generally uses 'unsigned long' for memory addresses anyway. This change required fixing several assumptions about integer types in the arm code. - Use _Bool as the boolean type. This is a specialized boolean type that was introduced in C99, and is preferrable over hacking booleans using integers. romcc sadly does not support _Bool, so for that we stick with the old uint8_t. - Drop the least and fast integer types. They aren't used anywhere in the code base and are an unnecessary maintenance burden. Using the standard fixed width types is essentially always better anyway. - Drop the UINT64_C() macro. It also isn't used anywhere and doesn't provide anything that a (uint64_t) cast doesn't. - Implement the rest of the MIN and MAX numerical limits. - Use static assertions to check that the integer widths are correct.

2019-02-22symbols.h: Add macro to define memlayout region symbolsJulius Werner
When <symbols.h> was first introduced, it only declared a handful of regions and we didn't expect that too many architectures and platforms would need to add their own later. However, our amount of platforms has greatly expanded since, and with them the need for more special memory regions. The amount of code duplication is starting to get unsightly, and platforms keep defining their own <soc/symbols.h> files that need this as well. This patch adds another macro to cut down the definition boilerplate. Unfortunately, macros cannot define other macros when they're called, so referring to region sizes as _name_size doesn't work anymore. This patch replaces the scheme with REGION_SIZE(name). Not touching the regions in the x86-specific <arch/symbols.h> yet since they don't follow the standard _region/_eregion naming scheme. They can be converted later if desired.

2015-11-11arm64: mmu: Make page table manipulation work across stagesJulius Werner
In order to have a proper runtime-modifyable page table API (e.g. to remap DRAM after it was intialized), we need to remove any external bookkeeping kept in global variables (which do not persist across stages) from the MMU code. This patch implements this in a similar way as it has recently been done for ARM32 (marking free table slots with a special sentinel value in the first PTE that cannot occur as part of a normal page table). Since this requires the page table buffer to be known at compile-time, we have to remove the option of passing it to mmu_init() at runtime (which I already kinda deprecated before). The existing Tegra chipsets that still used it are switched to instead define it in memlayout in a minimally invasive change. This might not be the best way to design this overall (I think we should probably just throw the tables into SRAM like on all other platforms), but I don't have a Tegra system to test so I'd rather keep this change low impact and leave the major redesign for later. Also inlined some single-use one-liner functions in mmu.c that I felt confused things more than they cleared up, and fixed an (apparently harmless?) issue with forgetting to mask out the XN page attribute bit when casting a table descriptor to a pointer. BRANCH=None BUG=None TEST=Compiled Ryu and Smaug. Booted Oak.

It encourages users from writing to the FSF without giving an address. Linux also prefers to drop that and their checkpatch.pl (that we imported) looks out for that.

2015-08-28t210: Move page tables to end of TZDRAMFurquan Shaikh
BL31 makes an assumption that TZDRAM always starts at its base. This was not true in our case since coreboot page tables were located towards the start of TZDRAM. Instead move page tables to the end, thus satisfying the assumption that BL31 base is the base of TZDRAM as well.
