include: Make unprivilege load/store functions as non-inline functions

2019-05-24T02:52:47Z

Currently, the unprivilege load/store functions are inline functions. We will be extending these functions to track whether a page/access fault occurs when we execute unprivilege load/store instruction. To make things simpler and debugable, we reduce number of places which can potentially generate a page/access fault by making all unprivilege load/store functions as regular (non-inline) functions.

lib: Add a simple brain-dead allocator to manage extra scratch space

2019-05-24T02:52:47Z

We have extra space above scratch space (sbi_scratch) which we are currently using to manage per-HART IPI data and TLB request management. In future, more parts of OpenSBI will use the extra scratch space so it will become difficult to manage extra scratch space using just defines and macros. This patch adds a simple brain-dead allocator to manage extra scratch space. This allocator never expects anything to be free-ed hence it keeps incrementing to next allocation offset until it runs-out of space. In future, we can have more sophisticated allocator which will allow us to re-claim free-ed space and also allows us to track owner of allocated space.

lib: Add misaligned load/store trap handling

2018-12-26T05:44:22Z

We generally don't get misaligned load/store traps from Linux/U-Boot compiled using GCC 8.2 or higher but this is not true with older GCC toolchains. To tackle this we add misaligned load/store trap handling adopted from BBL sources but much more simpler. (Note: BBL sources can be found at https://github.com/riscv/riscv-pk.git) Signed-off-by: Anup Patel
