Re: [U-Boot] [PATCH v2 4/8] x86: quark: Lock HMBOUND register before jumping to kernel

When Linux kernel boots, it hangs at:

[ 0.829408] Intel Quark side-band driver registered

This happens when Quark kernel Isolated Memory Region (IMR) driver tries to lock an IMR register to protect kernel's text and rodata sections. However in order to have IMR function correctly, HMBOUND register must be locked otherwise the system just hangs.
