utils: Remove tinyfdt.c

2019-06-19T04:25:13Z

tinyfdt.c was originally added to provide a minimal implementation of fdt parsing. However, we have already included libfdt in OpenSBI for more complicated operations. Remove tinfdt and replace its functiolity using libfdt. Signed-off-by: Atish Patra Acked-by: Anup Patel

lib: Rename string.x to sbi_string.x

2019-06-19T04:18:59Z

All string functions are part of libsbi. It makes more sense to rename them to sbi_string.x as the libsbi can be linked with external libraries that can have similar implementation. Signed-off-by: Atish Patra Acked-by: Anup Patel

platform: Move platform common to lib/utils.

2019-06-19T04:18:56Z

Currently, platform/common contains platform/non-platform specific common minimal drivers and libraries. This is helpful is all platforms are built within opensbi framework. Move them to lib/utils so that any external platform code also can reuse the minimalistic drivers or other common libraries. This patch doesn't introduce any functional changes.

lib: Include helper libc functions directly in libsbi.

2019-06-19T04:18:54Z

libsbi needs some of the custom libc functions. It should be directly included in libsbi instead of platform specific libraries. Signed-off-by: Atish Patra Acked-by: Anup Patel

lib: Handle page/access fault caused by unpriv load/store

2019-05-24T02:52:47Z

The unpriv load/store instruction from M-mode can cause page/access fault to M-mode if S-mode page table did not have mappings OR it did not have PMP access permission. To tackle this, we redirect trap back to S-mode if unpriv load/store instruction traps in M-mode. Signed-off-by: Anup Patel Reviewed-by: Atish Patra
