Thanks, Peng. Move patch 3 in v2 to 1st patch in v3 and add Fixes tag Per Daniel IMX_RPROC_ANY in patch 3 Per Mathieu Update comment and commit log in patch 5, 6. NXP SDK provides ".interrupts" section, but I am not sure how others build the firmware. So I still keep patch 6 as v2, return bootaddr if there is no ".interrupts" section. V2: patch 4 is introduced for sparse check warning fix This pachset is to support i.MX8M and i.MX93 Cortex-M core firmware could be in DDR, not just the default TCM. i.MX8M needs stack/pc value be stored in TCML entry address[0,4], the initial value could be got from firmware first section ".interrupts". i.MX93 is a bit different, it just needs the address of .interrupts section. NXP SDK always has .interrupts section. So first we need find the .interrupts section from firmware, so patch 1 is to reuse the code of find_table to introduce a new API rproc_elf_find_shdr to find shdr, the it could reused by i.MX driver. Patch 2 is introduce devtype for i.MX8M/93 Although patch 3 is correct the mapping, but this area was never used by NXP SW team, we directly use the DDR region, not the alias region. Since this patchset is first to support firmware in DDR, mark this patch as a fix does not make much sense. patch 4 and 5 is support i.MX8M/93 firmware in DDR with parsing .interrupts section. Detailed information in each patch commit message. Patches were tested on i.MX8MQ-EVK i.MX8MP-EVK i.MX93-11x11-EVK Peng Fan (6): remoteproc: imx_rproc: correct i.MX8MQ DDR Code alias mapping remoteproc: elf_loader: introduce rproc_elf_find_shdr remoteproc: imx_rproc: add devtype remoteproc: imx_rproc: force pointer type remoteproc: imx_rproc: set Cortex-M stack/pc to TCML remoteproc: imx_rproc: set address of .interrupts section as bootaddr drivers/remoteproc/imx_rproc.c | 57 +++++++++++-- drivers/remoteproc/imx_rproc.h | 7 ++ drivers/remoteproc/remoteproc_elf_loader.c | 93 +++++++++++++--------- drivers/remoteproc/remoteproc_internal.h | 2 + 4 files changed, 114 insertions(+), 45 deletions(-) -- 2.37.1 _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
