Re: [U-Boot] [PATCH 14/22] x86: fsp: Mark the first 64K low memory as reserved

Mark the first 64K memory as reserved as well since U-Boot uses this memory region for things like VBIOS execution in real mode. After kernel resumes, it checks low memory range per config option CONFIG_X86_RESERVE_LOW which is 64K by default to see whether a memory corruption occurs during the suspend/resume.
