I saw on IRC than Russell managed to have a more coherent date with this series on his 8040 based board. For the record, as the U-Boot on this board didn't provide a "date reset" command for the RTC located on CP slave, then Russell needed to do the following: =20 devmem2 0xf428401c w 0 devmem2 0xf4284018 w 0x2000 followed by: date 021612342017; ntpdate ...; hwclock -uw =20 But this issue was related to the bootloader not to the kernel. The other potential issue seen by Russell was about the GIC mapping for the interrupt, but here again this mapping was done by the 1st stage bootloader. =20 Given this information would it be OK to applied this series?No it is not. As I already pointed out, the interrupt for the 8040 is GIC_SPI 71 _not_ GIC_SPI 77 as you have it in this series. Both CP110's on Armada 8040 have a default mapping of ICU 77 to GIC 71.
OK so I am sending a v2 with this fix. Thanks, Gregory
