Hi Samuel,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on next-20200507]
[also build test ERROR on dm/for-next]
[cannot apply to v5.7-rc4]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use
Record PC value from regs[15], it should be regs[32] in REGS_ABI_32 mode,
which cause perf parser the backtrace failed.

as stm32f429's internal flash is 2Mbytes and compiled kernel
image bigger than 2Mbytes, so we have to load kernel image
to sdram on stm32f429-disco board which has 8Mbytes sdram space.
based on above context, as you knows kernel running on external
