Subject: boot hang issue on S5PV210 with the latest kernel
Hi all,
I am testing the latest kernel on my S5PV210 ARM boards. I found I
have to add the kputc debug in __armv7_mmu_cache_on in
boot/compressed/head.S:
mov r11, r3
kputc #'x'
mov r3, r11
Without the above kputc, the kernel boot hang, there is no any output on UART
Any suggestions?
Thanks,
Yong
