* minute-ia: ish software panicDenis Brockus2019-06-111-14/+4
| | | | | | | | | | | | | | | | | | | Adding functions for software panic to ISH. This includes panic_set_reason, panic_get_reason and software_panic. Added extra output when a software panic is detected. Had to touch nds32/panic.c in order to make panic_sw_reasons common. BUG=b:134502392 BRANCH=none TEST=Verified with crash assert, with CONFIG_DEBUG_ASSERT defined Change-Id: Iebfe62a7dcd59b4bbed82b450dfd44cc8eaed1da Signed-off-by: Denis Brockus <dbrockus@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/ec/+/1648958 Reviewed-by: Jack Rosenthal <jrosenth@chromium.org>

* nds32: pre-fix for the latest official toolchainDino Li2016-12-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We use the latest nde32 official toolchain to verify the bug of GP-related instruction was fixed (we can remove "-mno-gp-direct" flag to save code space), and code optimization. We got some error on official toolchain, so we fix them as well: - "break" instead of "trap". N8 CPU does not support "trap" instruction to generate an unconditional trap exception, but no error occurred while compiling by using current GCC toolchain (this will trigger a reserved instruction exception, so "ASSERT()" still work). We use "break" to generate a exception in this change. - "li" instead of "la". To fix the error: "Error: la must use with symbol". Also fix: - The "_bss_start" has to be word-aligned because we use "lwi" instruction to load a word from the memory into the general register. BRANCH=none BUG=none TEST=1. console command "crash assert". 2. check registers settings: f02030h, f0203eh, and f02044h.
