Hi, Russell and Konstantin,
Our one ARMv7 Cortex-A7 based dual core SoC with LPAE support could not boot since next-20140811 on the linux-next tree,
I notice that there is a commit 7fb00c2fca4b6c58be521?, ?ARM: 8114/1: LPAE: load upper bits of early TTBR0/TTBR1?.
Revert that commit the SoC boots successfully, do you have any suggestion on this, thanks.
related SoC hardware and kernel configurations are:
DRAM PHYS address: 0x80000000
CONFIG_VMSPLIT_2G
CONFIG_PAGE_OFFSET=0x80000000
CONFIG_ARM_LPAE
Best Regards,
Jingchang
