Currently, ipq807x only covers Qualcomm IPQ807x SoC-s. However, Qualcomm also has IPQ60xx and IPQ50xx SoC-s under the AX WiSoC-s and they share a lot of stuff with IPQ807x, especially IPQ60xx so to avoid duplicating kernel patches and everything lets make a common target with per SoC subtargets. Start doing that by renaming ipq807x to qualcommax so that dependencies on ipq807x target can be updated. Signed-off-by: Robert Marko <robimarko@gmail.com>

Subject: [PATCH] soc: qcom: mdt_loader: Fix unconditional call to
|
|
scm_pas_mem_setup
|
|
|
|
Commit ebeb20a9cd3f ("soc: qcom: mdt_loader: Always invoke PAS
|
|
mem_setup") dropped the relocate check and made pas_mem_setup run
|
|
unconditionally. The code was later moved with commit f4e526ff7e38
|
|
("soc: qcom: mdt_loader: Extract PAS operations") to
|
|
qcom_mdt_pas_init() effectively losing track of what was actually
|
|
done.
|
|
|
|
The assumption that PAS mem_setup can be done anytime was effectively
|
|
wrong, with no good reason and this caused regression on some SoC
|
|
that use remoteproc to bringup ath11k. One example is IPQ8074 SoC that
|
|
effectively broke resulting in remoteproc silently die and ath11k not
|
|
working.
|
|
|
|
On this SoC FW relocate is not enabled and PAS mem_setup was correctly
|
|
skipped in previous kernel version resulting in correct bringup and
|
|
function of remoteproc and ath11k.
|
|
|
|
To fix the regression, reintroduce the relocate check in
|
|
qcom_mdt_pas_init() and correctly skip PAS mem_setup where relocate is
|
|
not enabled.
|
|
|
