[U-Boot] U-Boot X86 bootstart

Hello,

I've been digging a bit in X86 bootstart asm code and found possibly wrong code, as far as I understand:

In u-boot/arch/x86/cpu/start.S, there is piece of code to disable caches:

/* Turn of cache (this might require a 486-class CPU) */ movl %cr0, %eax orl $(X86_CR0_NW | X86_CR0_CD), %eax movl %eax, %cr0 wbinvd

, which perfectly makes sense to me. What doesn't really make sense then is:

/* Turn of cache (this might require a 486-class CPU) */ movl %cr0, %eax orl $(X86_CR0_NW & X86_CR0_CD), %eax - AND HERE??? movl %eax, %cr0 wbinvd

in start16.S of the same directory.

Is is wrong or not?

Thanks a lot, Ondrej Kupka
