According to the i.MX25, i.MX31 and i.MX35 RM, all three SoCs have ROM
at address 0x00000000 and no RAM at address 0xffff0000, so they most
certainly have the same kind of issue as i.MX27, but there is no
indication that the indirect vectors table is always the same, and it
is quite probable that it is located at a different place for each SoC.
So in order to solve the issue, we would need a dump (or better yet a
disassembly) of ROM addresses 0x00000000 to 0x0000001F for each of the
three SoCs.
