Ah, I think you meant "we are not always aware whether a device uses cmdline
as partition parser" and not "we are not aware of device that use cmdline as
partition parser". At least this would make more sense here.
Other question regarding the changes in 11-ath10k-caldata: You've dropped the
caldata_extract in various places which would usually copy the pre-cal (or
cal) data from the ART partition to /lib/firmware/$FIRMWARE. But I see in
various places that there are things like ath10k_patch_mac still in there.
Take for example linksys,ea8500:
- caldata_extract "art" 0x5000 0x2f20
ath10k_patch_mac $(macaddr_add $(mtd_get_mac_ascii devinfo hw_mac_addr) 2)
I thought that a "pre-calibration" nvmem-cell would then be used by ath10k to
get the (pre-)cal data . So it doesn't make a lot of sense to me that there
is now still a ath10k_patch_mac which tries to operate on
/lib/firmware/$FIRMWARE (which should not exist). The script section shouldn't
be called in the first place because the "pre-calibration" nvmem-cell has a
higher priority in ath10k, right? I can also see the changes
to qcom-ipq8064-eax500.dtsi but no mac address fix.
