R-b added to first patch and all rebased on top of master. The Shippable CI should run and (hopefully) pass. |

For "scripts/symbolize.py: print ELF sections after MMU region information" |
Signed-off-by: Jerome Forissier <[email protected]> Reviewed-by: Jens Wiklander <[email protected]>
When processing a user TA abort dump, list the ELF sections that are
mapped in each MMU region. For example (the lines modified by this
patch are prefixed with >>):
User TA undef-abort at address 0x10574e

Shippable fails due to a checkpatch warning (line too long in commit message). Let's ignore that since it is a copy/paste of the tool output. |
